Welcome to Bogleheads on Investing, podcast number 17. My guest this month is Joe Davis, Vanguard's global chief economist, and our topic is Vanguard's Economic and Market Outlook for 2020, the New Age of Uncertainty. My name is Rick Ferry and I'm the host of Bogleheads on Investing. This podcast, as with all podcasts, is brought to you by the John C. Bogle Center for Financial Literacy, a 501C3 Corporation. In this podcast, we have Dr. Joe Davis, Vanguard's global chief economist and head of Vanguard's Investment Strategy Group, whose research team is responsible for helping to oversee the firm's investment methodologies and asset allocation strategies for both institutional and individual investors. In addition, Joe is a member of the Senior Portfolio Management Team for Vanguard's Fixed Income Group. Today we're going to be discussing a new report, Vanguard Global and Economic Market Outlook for 2020, the New Age of Uncertainty. The report is available online at vanguard.com. With no further ado, let's bring in Dr. Joe Davis. Welcome, Dr. Thanks, Rick. You can call me Joe, and really, thanks for having me. Well, thank you so much for being on our show today, Joe. We're really fans of your work, and you've given some fantastic presentations to the Bogleheads over the years. What I wanted to do today was get your team's outlook on 2020. But before we start there, who is Joe Davis?  Sure. I actually grew up 10 minutes from the Vanguard building I work in outside of here outside of Philadelphia. I was attracted to Vanguard because I was an early investor in the early 90s, and that thanks to my dad, he had the wisdom to show me how to start investing. I came out of graduate school with a PhD in economics. I was actually thinking I would end up in up on Wall Street in New York. But again, my dad said, why don't you apply to Vanguard? So I did. My resume found its hands into a group that they were just starting, a group that I now have the great pleasure of leading. I thought leadership group, effectively a research group. And that was 17 years ago, Rick, and so it's amazing. I count myself very lucky and fortunate to work with such a great company. And our group has grown from in those early days in 2002, 2003, from fewer than ten crew members to now we're over 65 and growing and we're in multiple countries, including Europe and Asia. So it's an exciting group to be a part of, and I count myself fortunate. One of the Bogleheads did ask, who is the audience for the work that you're doing? Because, you know, as Bogleheads, we're basically following by-hold strategies. You do a lot of work and you make a lot of predictions about GDP growth, earnings growth. And we've actually put out marked forecasts. And so, you know, how does a typical individual investor take that? Is it supposed to be actionable, or who's it for, and how should it be taken? Yeah, I see three primary users or use cases for our annual publication. First is just, I think for many, is just to orient or to help provide investors with what are reasonable expected returns for the portfolios or investment that they are already in. Right, this is not and has never been and never will be supposed to be used as market timing calls and short-term prognostications, which I quite frankly, I see from many in the industry. This is to help inform, you know, what is a reasonable expect to return on a portfolio to help want to achieve one's goals. And before I came to Vanguard, we did not have forward-looking expectations. And so that's been a big step forward for many, including internally at Vanguard. Secondly, this is an input into the active managed process. So for those investors that are perhaps in our actively managed bond funds, whether they're taxable or they're municipal, our economic outlook is an important ingredient because in those funds we are taking modest active risk, meaning trying to outperform a benchmark in a very risk-controlled way. And to try to do that, one of the many levers that the portfolio management team will pull will be a risk assessment of what the markets are pricing in from an interest rate or say an economic growth outlook. And then how do we view the risk skewed relative to that sort of view in the marketplace? Again, all in the interest and the objective to try to modestly and incrementally add value for the shareholder in the funds. Many times we view that as just as much not taking excessive risk as it would be for trying to take more risk. And a great example is even right now where I can feel and can sense in the market is becoming increasingly overly optimistic on growth. We see pockets of the financial markets where I would view is frothy risk taking. And so for a long-term investor that are in these funds, we are managing based upon our outlook to not be as aggressive as other funds may be, which we believe in the long run will reward our investors in those funds. And then the third would be for those that would retain Vanguard from a device perspective, because again, for certain investors who may have either a fixed spending goal, maybe an institution that has to generate a certain spending flow from their portfolio or others, the variations and expected returns in the marketplace, again, not in the one year, but in the next five or 10 years, can then have implications for the asset allocation strategies that they would pursue. For some that have a very, very long horizon, I would tell those investors that they should ignore all outlooks, including our own, if they have a very long horizon, because the buy and hold, stay of the course is very much appropriate. But for years when I came to Vanguard, I think what a common refrain would be would be, hey, does Vanguard have an opinion on X or Y? And I think many investors want to stay of the course, but sometimes they also struggle with the headlines. And so one of the other primary objectives of this piece is to say, yes, these are the probabilities that may occur in the future, whether it's economic risk or financial market volatility, that we have thought about it and it's reflected in our thinking and in the advice that we give clients. So basically three ideas. Number one, your individual investors already have their portfolio set and their asset allocation. And so it's just sort of long-term estimates of expected return from bonds and equities so that they can do some planning. And the number two, it's for your active funds so that they can maybe do some tailoring and potentially pick up some excess return or some alpha. And last, you're saying there are large institutional investors who actually buy your research or pay you to give this assessment. And those are the three areas where you find people use your report. Yeah, and some will just use it as an input into assessing the risk. Because then in the day, all of us as investors are making decisions on their uncertainty in terms of our asset allocation. Even if we haven't changed our asset allocation, it's still a decision, whether implicit or explicit. And so the value that we hope to bring is to convey the range of ultimate outcomes, particularly with respect to returns. And respectfully, I think we do it in a very rigorous way. I mean, we take some of the best techniques in academia, but we do it in a way where we convey, I believe, the market outlook as it should be, which is a range of outcomes. We're not offering short-term point forecasts. You know, Vanguard doesn't have an S&P 500 target for the end of 2020. I actually kind of laugh at those sort of outlooks. And so I think if we can convey the range of outcomes and the rationale for why it is today versus perhaps what it would have been 10 years ago, you know, I think that can be a value. I'll give you an example where it helps some investors, Rick, like 10 years ago, you know, our first annual outlook publication came out in the 2009 period, which you can recall. It was not a fun time in the markets. And we had a great deal of clients wondering, should they even be in equities at all? And this publication helped some in the sense that we said, listen, the economic environment for the next several years is going to be where I have elevated unemployment. It's going to be fairly tepid growth. Yet the outlook for the financial markets, as best we can assess over the next five or 10 years, believe it or not, are actually the odds are tilted towards higher than average expected returns. And if anything, we turned it out to be a little too low in our projections, our range. It came in a little bit higher than expected. But I think that was helpful because behaviorally and emotionally at that time, it felt as if, you know, I would even have friends and colleagues in my family that said, listen, I feel like I really should get out of the market. And so even having that conversation and the rationale for why the expected returns were even higher, you could show that for some that are really mathematically inclined, you could show them statistical rigor why historically, there's a reason to believe this. I think that had a service to investors. This publication is not in any way intended to pick market tops and bottoms. We are really trying to inform investors that this is the range of expected returns that you could see in your portfolio. I think that your estimate of a globally diversified 60% stock, 40% bond portfolio, you have a range of four to six. So call it the midpoint about five. It seems to me to be very realistic and a good planning point. We have to have something to plan with. We have to have some number to use. And I think that your numbers are as good as anything anybody could come up with. But the way you get to them, though, in reading through your report, you start out by looking at, it seems, the business cycle. Could you explain about the business cycle and what do you think we are? Well, we're at one of the later stages of the business cycle in the sense of how long this global expansion, which is going on more than 11 years. And we expect it to continue in the 2020. And why that matters, assess where you are in the cycle. It has implications for two things. One is, historically, at least, when you're in the late stages of any expansion, two things tend to emerge. One is you tend to have the financial markets not only performing very well, which is good, but you tend to have financial markets outperforming the fundamentals. And so in that environment, investors can feel very good, but precisely because of how we approach the forward-looking return, expect the future returns become more modest. And so it's important to identify where you are in that cycle at a high level, because that does inform how one should be thinking about everything from rebalancing to the return estimates that they assume. We estimate that the global economy will, more likely than not, continue to expand. But growth will not accelerate, at least to the extent that at least parts of the stock market increasingly already anticipate. And so it will be one of these somewhat of a paradox in 2020 is that we could have economic growth, not be negative, the expansion continue, and yet you could have the financial markets underperformed for a time. And just to be prepared for that, we do not see strong evidence of financial market bubbles which occurred late in the business cycle, say in 1998, 1999, you could call the NASDAQ, right, and the .com. We don't see the imbalances in other parts of the economy, much like we saw in housing, certainly in late 2006 and early 2007. There are, though, imbalances, I think, at the high level of corporate debt, high level of sovereign debt in some countries. And we've had extended period of very loose monetary conditions generated by central banks. So that's what keeps us up at night a little bit, but I think at the end of the day, it's not the worst outlook. It's just one I think we're just trying to set lower, but I still think reasonable and they're not bearish. It's not a bearish outlook on either the world economy or the financial market. I find it interesting that a year ago, after the Fed had increased rates three times last year, but then the forecast was for three more rate increases in 2019. But in fact, what we had was three rate decreases rather rapidly. And in addition, around the world, monetary policy makers just been decreasing. Is that a warning sign? I mean, yeah, I mean, one of our outlook last year, the theme of it was down but not out and it was a boxing analogy, meaning the global economy was gonna weaken significantly based upon the leading indicators which we track very closely internally at Vanguard, again used in the portfolio management process and they weakened in China in early 2018, they weakened in the US in 2018. And so that's foretold, at some point in 2019, roughly around the summer that we were gonna have what we called growth scares. And we published that in early 2019 that we were more likely than not gonna see a slowdown growth which many did not at least anticipate a severity. Now, in part because of that slowdown, our probability of recession almost approached 50% which unnerved us a little bit because obviously if you have a recession, the equity market historically has been down at least 20%. The irony of it is that I think the Federal Reserve and some other central banks were observing and have similar models as we do, Rick. And so I think that ultimately they reacted much more aggressively and so cut rates, I think which stabilized the situation. Why frankly, they reacted more strongly than I would have anticipated. I could have perhaps seen one cut because it was really just in the bond market, particularly the shape of the yield curve that was given the most ominous sign of potential recession but other indicators in the, both in the economy, outside of manufacturing as well as the equity market were not displaying the same signals which is why our probability's never got above 50%. So it did surprise me how aggressively they reacted but then that was one of the reasons why the second half of the year, the financial markets performed as well as they did. Not the only reason but that certainly was a primary catalyst. Yeah, we went from an inverted yield curve to now it's getting to look almost more like a normal yield curve as longer term rates continue to creep up here and short term rates come down so there's no longer an inverted yield curve. Now some people will say, well, that's good. That means no recession is coming. You know, our probability of recession uses all the signals in the marketplace but we combine them in a way that's actually more accurate in general than just the bond market alone or the stock market alone. It's actually the power of a diversified set of signals.  We use a diversified portfolio of signals over a hundred in all that you can use to assess what the risks are in the economy and it's improved although we're not completely out of the wood yet. One of the reasons why, although we don't see a recession in 2020, there's gonna be uneven growth next year. And so I think the bond market's starting to come to the realization of that. The equity market, quite frankly, has priced in a much better economic outcome than I even think is reasonable. And so that's why I still think in the near term we just have to be prepared for some volatility. I've been reading a lot about manufacturing declines in manufacturing activity. In fact, the Kansas City Fed recently announced that their district has had, I think it's several months in a row now, manufacturing decline. And globally they're curious to continue to be this manufacturing decline. And how is that impacting into your GDP growth estimates? It's been a primary factor. It's been a factor of why we foresaw significant global slowdown this year, relative to 2018, which occurred in almost every market. One of the reasons I fed into the central bank switching course in various markets around the world. And one of the reasons why we're less bullish show to speak than I think many increasingly are for 2020. There's three reasons why the manufacturing sector in particular have been underperforming or in many parts of the world, including in the United States, contracting, meaning in recession. One was set in motion two or three years ago and that was a high level of inventories in the manufacturing sector. And so there's generally been in the past 10 years and three years sort of expansionary sort of tailwind to manufacturing and then it slows down for a time. And you could see that clearly in our signals and we're not completely done that but we're still working through it. And that's why we've seen weakness across the manufacturing front. Secondly has been in motion for 10 years and that is the structural slowdown intentionally in China. As they continue to try to rebalance and escape what many call the middle income trap, meaning become more developed, become more consumer based. And they've been successful to date but the past days of even 6% growth I think are over and that has particularly impacted parts of the manufacturing sector. But the third one and clearly the most cyclical one has been the trade tension between the US and China. We model that as best we can and it's the high level of uncertainty. In fact, that's the title of our publication this year, the new age of uncertainty that why we call it that we believe that this recent significant rise in uncertainty is unlikely to unravel quickly. That has led to slower than expected business investment and that primarily hits or certainly hits the manufacturing sector. So one of the byproducts of this slowdown in manufacturing and global manufacturing are corporate profits. Now, S&P earnings have been increasing in part because of tax cuts, in part because of buybacks. So we have this divergence between S&P earnings that are increasing and national profits based on GDP, national accounts that has actually been declining. And a Wall Street Journal article recently brought this to light I think a couple of weeks ago. Can you comment on that? Profit margins are still fairly robust when you look at the aggregate data. I mean, they have weakened in a growth rate perspective but I would say there's two things going on. One is just the high level of profitability. It's particularly impressive in the United States. It's one of the reasons why I think the US has been among the stronger or at least the more stable economic performers and equity market performers over the past several years is just the high level of profitability. Now that the rate of increase has clearly slowed. Part of that is just due to the economic environment. The weakness, particularly we've seen overseas, there was a point in time this year which we estimate China was growing well below 5%, perhaps as low as three or four, which wasn't reported in the statistics. We saw significant weakness in other emerging markets and in Europe, Germany and others, which again, part of them are exposed to weakness in China. And so we've seen a deceleration in that. And then of course the equity market has continued to perform well. I think in part because corporate profitability didn't go significantly negative when recession odds were being discussed. But I think for just other just sentimental reasons and so you've had this valuation, the P ratios have just widened further because earnings haven't been keeping up to the same level of appreciation as prices. And then as you noted, there's been a more of a longer term, four or five years, the M&A activity, the buyback activity, more so than the rate of natural investment in companies own growth prospects. Something I would call sometimes financial engineering has been significant pace. And then another reason which is not often discussed and it won't change quarter to quarter, but another reason are contributed to the high level of corporate profitability. It is a little modestly concentrated in a handful of firms. And part of that is I think the nature of the digital economy, what I would call network effects. And so very large companies may be able to maintain high profit margins or high profit levels. This weather growth is accelerating or decelerating. There's longer term issues and behaviors. I think that can help explain the high level corporate profitability. But then there's also the business cycle effect which tends to get most of the press attention. Let's move into the labor markets because I have a real question about this. You know, I'm a baby boomer. I'll be 62 next year. And I see all of my compadres from high school and college getting ready to leave the labor force in over the next year or two or three. And if we get a lot of people leaving the labor force because they're retiring, how is that gonna affect things like inflation, demand, so forth? Yeah, I mean, it's an important issue. It's, you know, I would put the aging of the workforce. Along is just the slower rate of population growth we have in the US and in other countries versus say 10 or 20 years ago that slower demographic forces have already had I think a clear imprint on a number of things. One is just what are the expectations for growth? What's the natural run rate, right? So called the average speed limit for any economy. You know, we used to talk in the United States that a reasonable growth rate for say real GDP was 3% on the 90s. For the good old days. Yeah, good old days. No, of course that was propped up by leverage which we ended up paying the price for in terms of the housing market and in the global financial crisis. But yeah, the natural run rate for the US economy right now is slightly below 2%. One of the reasons for that is the aging of the workforce and just the retirement population growth is not negative but it has clearly slowed. And so the potential growth rate of the economy is lower. Now that does have an implication for inflation. You would say then if you have slower potential let's call it one and a half GDP growth. And we've been growing in the United States roughly 2%, the past four or five years, right? You would then expect inflation to rear its head sooner because even though you're growing slower than historical averages you're going above the speed limit, right? So inflation is like a speeding ticket, right? You only get that speeding ticket if you're going above the speed limit. If I will compliment our team, we put our finger on this four or five years ago that there's been other forces that have been more than offsetting the inflationary pressures that you would think from a less slack in the economy which is really one way of saying regardless of your growth rate if you have fewer available workers eventually you're going to see wage pressures and everything, right? But one of those forces is digital technology which has been a suppressant keeping prices down. It's everything from online sales to just cheaper costs of manufacturing certain products and services. And we were one of the first firms to actually quantify what that drag is. So what this means, I think the demographic imprint going forward is it's one of the reasons, not the only one, one of the reasons why interest rates are lower today in the United States and in Europe and in other parts of the world is because of slower population growth. And again, it's tied to lower expected economic growth which has led to the lower interest rates. There's a point with which it'll reverse when the global economy, it's roughly five years from now and again, this is very slow moving, moving it won't happen in one month in any one year but with an aging population over time that'll mean that there will actually be a little bit less demand for very safe assets. And so, which has been a significant boost to fixed income markets as well as the lower rate of inflation. We had a research report on what are the investment implications of an aging world and a world with slower demographic patterns. And what we did conclude was that it is modestly inflationary but those sort of headwinds don't really come into play until roughly 10 years from now. Demographics is there's competing forces through some things that can be positive to the financial markets, bonds or stocks from demographics. There's other things that can be potentially negative but these are slow moving effects and so it's important to say over what horizon may they matter and also to appreciate the other forces because demographics are far from the only one that are affecting an economy and financial market at any period of time. I'm gonna lump these next three questions into one. It has to do with your forecast for Fed cuts, number one. And secondly, do we get to a point where rates are so low that we're pushing on a string, another old saying on Wall Street. Has the Fed's hammer been taken away because interest rates get so low? And then finally, what are the prospects for the U.S. to hit negative interest rates like we see in a lot of the other developed markets? Yeah, let me take the last one first Rick. I think the odds of us seeing negative interest rates in the United States are very low and much lower than other countries. I wouldn't assign a probability, any outcome zero. That would be foolish but I think there's a number of reasons why we won't see negative in the United States. I think one of the reasons is the importance of short-term funding markets, including money market funds, which is really a strength and diversified source of funding for corporations and lending for short-term collateral. And so there's both technical as well as fundamental reasons why I think the Federal Reserve will be reluctant to test negative interest rates. And I am not a fan of negative interest rates. I'm more in the minority in my profession. I can't prove this but I think history will show that the modest negative interest rates we see in both Japan and in Europe are a mistake. And then we have not seen significant lift from either of those economies with negative interest rates. Now again, I'm not expecting a move from zero interest rate to negative .25% is gonna lead to fundamental growth, right? That would be an unfair criticism but I think the risk that negative interest rates play and why I think we won't ultimately see them in the US is that there is a risk that when a country sets negative interest rates that you can actually lead some investors to start to believe that we'll have deflation meaning falling prices or to lower their inflation expectations which is precisely the opposite outcome of the rationale for taking interest rates below zero to begin with. Yeah, unintended consequences. Unintended consequences. So I don't have proof in that but I think there is now at least some doubt in some central bankers mind and so I don't think we'll see it. I think in the next recession what we will very likely see though is the Federal Reserve cut interest rates to zero much more quickly than they may have done in the past in large part because they don't have as much room to cut. And then secondly, although again, it may only be modest effects but I think we will see potentially expansion of the balance sheet. And then thirdly, what will gain much more discussion will be the pairing of monetary policy with fiscal policy in terms of stimulus. This will ultimately become a politically charged issue and my job is to assess the economic ramifications of this. I do believe central bankers generally speaking are already pushing on a string. I don't think the Federal Reserve should be pushing on the string. They are trying to at the end of the day maintain full employment and to get inflation actually higher than where it is. So the risk is in our outlook and one of the reasons why we think the next move by the Fed will likely be a cut and not a hike even though I personally wouldn't do it if I was on the Fed is likely because they want to make sure that investors still believe there'll be positive inflation in the future and they want to continue the expansion as long as possible. And again, those points are part of their mandate and charge. But we can all I think disagree about whether or not they should be cutting or not. We've debated that internally here at Vanguard but I've sat in the middle of debates and I've actually argued from both sides what surprises an economist, I use both hands but at the end of the day also my job is to assess certainly for the portfolio management teams not what they should do but what ultimately the Federal Reserve and others will do because that has the bearing on the financial markets. And so I think the bar is high for the Federal Reserve to cut the rates in 2020 but I think they're more likely to cut them than they are to raise them if our assessment of where the economy may unfold and inflation may unfold this year is right. It seems as though everyone hangs on every word the Fed says. You know, I think the central banks get too much attention in the financial markets because they don't control long-term interest rates and the stock market as much as I think people think they do. It seems like that the day of an announcement but they really don't influence it as much as they think. But I think the risk is they focus so much on preserving the expansion for so long that they may underappreciate some of the financial fraud that is building in the system. And so that's what I worry about and that's what I think one of the unintended consequences could be. Let's talk a little more about inflation. And if we define inflation by the prices we pay for all the goods or services we purchase as consumers, you know, in fact, one of the most perplexing questions in economics and hence in the financial markets, Rick, is actually why inflation has been stubbornly so low for so long. You know, almost any central bank without exception in the world aims to have inflation average roughly 2% and then they try to calibrate their short-term interest rates which they clearly control to try to hit that target, right? Knowing that it's a moving target and they're trying to hit it. For all the golfers out there, they're 100 yards from the hole, right? That's where they want inflation to be on the green, knowing that they'll never get a hole in one but put close enough. Could you explain why do central bankers want inflation? Yeah, it's actually a really good question that why any inflation at all? The reason why, generally speaking, most economists would argue that you want a stable inflation rate that's modest but positive is for two things. One is the belief that if you have a stable unexpected inflation rate that it makes it easier for planning purposes and so you're more likely to have modestly higher investment, hiring, and then consumption and there's some truth to that, right? Because if you can have better foresight on the increases in prices and so forth that reduces uncertainty, we all know the higher uncertainty, the lower say investment or spending all is equal. But the big reason why is because in any economy you have debt holders, right? So if you're a consumer and many of the listeners out there, myself included, well, my highest debt right now is the mortgage payment, which has a fixed term and it's in $6 amount. Why central banks want a positive inflation rate is if you had a consistently negative inflation rate, say negative three, negative 4% and you have a fixed debt level that makes paying back that much harder because your income is falling by 3% or 4%, right? But I think what economists do a poor job in saying is when they say it's bad to have deflation, what they should say and what I should say is that it's bad to have wage deflation because if we see sales at the store and that TV one's buying is 20% off and so that's not necessarily alarming. It's alarming when you have all prices going down including the prices for our labor, meaning our wages or our income and our salaries going down. That's what happened in the early 1930s which led to massive defaults, particularly among farmers and many companies. It froze consumer spending because I don't think anyone's gonna maintain their same level of consumption if their own income is not only falling but expected to fall further and we've seen glimpses of how pernicious this can be on and off in Japan for the past 20 years, right? Because the bond market today even in Japan and surveys, very few Japanese consumers expect inflation to be positive in the next five or 10 years and their wages don't go up by a significant amount and so that's where at the end of the day, so behind when you hear the Federal Reserve targeting 2% and everyone talks about the consumer price index, where that 2% came from, all the way back from Milton Friedman who won the Nobel Prize and even before that, it's really around this fear of avoiding wage deflation, particularly that we saw during the Great Depression. I recall when we had a negative inflation rate, just a very minor negative inflation rate a few years ago after the financial crisis, there was a big question on the minds of social security recipients where are they gonna cut my social security benefits which I think would have created riots in Washington, D.C. But imagine that in an environment, that's a great point, imagine that then not just for those that are social security beneficiaries, imagine if everyone had the concern that their paycheck was going to fall. Yeah, we actually had this in the United States on and off in almost every economic crisis in the 19th century. Many workers' wages were set by the day and so you had a lot of recessions. This is be long before the Federal Reserve was created. This is the 19th century where you had financial panics and so forth and you would have unemployment rates go up by 10 or 20% in a very short time and you'd have very deep, even if they were short, you'd have very deep downturns, very volatile period. One of the reasons for that is you would have wages that were falling significantly for periods of time in many cities in the United States on the Eastern seaboard and I know that because that's why I did my dissertation on it and so that is in grain and central bank theory, which I think could be, hopefully we don't experience too much but actually could be the irony of negative interest rates going forward is that at the margin, if that pushes down inflation expectations, that's the very outcome that they're trying to so hard to avoid. Let's get back to the global economy and talking about how this glut of manufacturing capacity overseas is affecting growth probably worldwide and also here in the United States and what is going on in Germany, what is going on in Japan, what's going on in China, what's going on in the UK and talk about Brexit and this whole global package that I'm asking you to talk about. The broader stroke is that the global economy is still expanding but growth is uneven and it's fragile right now. One of the underappreciated reasons we believe and we talk about in the outlook is the high level of policy uncertainty. Now, again, for those that are listeners, there's always uncertainty in the world and in life but there's times when policy uncertainty, you just mentioned one with Brexit. It's Brexit. It's US, China, trade tensions. It is other trade tensions with other countries between two countries all across the world and then there's actually increased political disagreement between and among political parties in almost every country around the world. There is strong statistical evidence including what we have done that when you have those high levels of uncertainty, you will tend to see a lower investment than you would otherwise which I think makes intuitive sense and that's one of the things that I think we see going on that we saw a drastic increase in policy uncertainty. Not just in the United States but we clearly saw it in China and one of the reasons for this cyclical slowdown that we're still working through this year, Rick and so that's still working through the system and Germany has a very high exposure through manufacturing particularly to the China consumer and it was the slowdown in the deterioration in private sector confidence in China sometimes which is not widely reported which led to a significant slowdown there which I think also increased the odds more recently that we saw a phase one trade deal because I think Chinese policy makers were battling on several fronts and so they were increasingly concerned that they were gonna have growth much weaker than expected and so they were I think a little bit more willing to at least have a phase one deal than what it would have been otherwise the case a few months prior. So I'd hang some of it, not all of it on uncertainty because it's by these measures that we track which are based upon news reports and other statistical measures to measure and quantify uncertainty which can seem ephemeral and tough to put your hands on. They're the highest that they've been in over 30 years. It's not surprising that it is at least stunting or hampering some investment. It isn't hampering the US consumer because he or she is still chugging along fairly well but it has been a reason why we've been mixed signals on the global economic front. So let me just go over quickly your forecast for US equities, non US equities and fixed income. So we all have a general framework to work from before I get to the questions from the Bogleheads. Your expectations or your forecast is over the next 10 years for US equities to give nominally that means with inflation included 3.5 to 5.5 annualized. Non US you're a little bit more optimistic 6.5 to 8.5 and I wanna get back to that in a minute and then fixed income two to 3% which means that a balanced portfolio of stocks and bonds 60, 40 somewhere between four and six and call the midpoint about five. But let's get back to the non US 6.5 to 8.5. Is that because valuations are lower? Is this by the way dollar adjusted meaning is this in US dollars so the dollar is going to contract? Yeah, okay. It's in US dollars, there is a currency effect but the primary reason why the expected range of returns are better than the US is it's your point record is valuation based which is again another great reason. You don't need this reason for a globally diversified portfolio but certainly the US markets have just outperformed every other part of the world. In fact the S&P 500 indexes arguably outperformed any investment public or private any part of the world. It's been that strong which has been great but it's also why the expected returns are among the lowest. So I'd say three broad points on our outlook for the financial markets. One is the principles of asset allocation will stand even in the lower return environment because over the next five to 10 years it is much more likely than not that a diversified stock portfolio will outperform bonds and a diversified bond portfolio will outperform a money market which is good to hear. Rarely would you see those expectations not be that it would have to be in a bubble like environment where you could actually reasonably generate other expectations but we don't have them. Secondly is that a globally diversified portfolio should outperform the US over the next five or 10 years. Finance theory tells us almost by definition that a globally diversified portfolio is quote unquote more optimal than a US only portfolio because you use diversified company risk across multiple markets, right? And you at least double the number of securities. So the global portfolio is always the most efficient one on the frontier. Over the next five or 10 years that's where evaluation comes in and that should be a little bit more of a tailwind for the European, you know, other developed markets and even parts of the emerging market. So now again, the US has outperformed the non-US over the past double years. It's more likely than not where valuations are that that will happen. And so we use valuations and how we model that's the sort of simulation engines behind the scene that we then show those results in the paper. We are the first to acknowledge we project ranges of returns because our models are good, but they're far from infallible and they have an era in them. But I can tell you our framework, we've published it in the academic community, our framework is generally twice as more accurate for long range forecasting, twice more accurate than either the historical average, which is what I think that most investors generally use if you don't have any other method, you just use the historical average. It's twice more accurate than that and twice more accurate than some of the popular ones that Bob Schiller made famous at Yale, part of the reason why he won the Nobel Prize. So we use those valuation approaches to inform the investors of what those expected returns are. So they're lower than historical average, you know, we compare those returns versus say the average returns since 1980. Well, I don't think we need any mathematical framework to tell us that the future returns will be lower than they were since 1980 because since 1980, you know, we've had, I think the best financial market performance in the United States that has ever been seen and could very well ever be seen at least for the next 100 years. Certainly in our lifetime. I mean, it's been a great run. Sometimes I don't wish I would be back in 1980 and 1982, but it was a great time. It didn't feel like it at the time, but we had double digit interest rates and we had PE ratios, you know, of below 10. I mean, I think the 10 year treasure was even higher than the PE ratio. And since that time, we all know interest rates have come down, the economy has expanded in valuation, multiples have actually increased. And so what a great starting point that has effectively run its course, which has led to double digit average returns for not just all equity portfolios, but even 80, 20 portfolios and at times 60, 40 portfolios. Yeah. So that doesn't mean the outlook is somber. It's just more of like going forward. It's a little bit, it's certainly below the recent, it's clearly below the recent starable average. And that's almost regardless of the, whether we have stronger or weaker economic growth this year coming. Yeah, I always look at the Dupont formula if you recall from your days of study you had. I mean, what are the three levers of return on equity? It is your operating leverage, it's your financial leverage, and it's your taxes. What that basically means is operating leverage is how much you actually get as a rate of return on the product that you're selling. But financial leverage is lowering of interest rates. As interest rates come down, you get a bump in return on equity because your finance and costs are low.  Well, we can't get too much lower on interest rates. We can't get too much lower on corporate tax rates. I mean, the only thing we have left is the operating leverage, which is productivity through technology. And as we talked about before, population growth, and that's at least the population growth side is beginning to decline. So I look forward and I say, well, where can the earnings growth come from over the next 10 or 15 years? It's not gonna come from your lowering of interest rates, it's not gonna come from lowering tax rates and baby boom is a retiring and we have slower population growth. So where does it come from? The one area that it could come from is the area that's actually arguably the most important for long-term growth and that's innovation. Economists call productivity, but think of the rate of innovation, how much more efficient, new product services, business lines, right? It's new technologies like the internet coming in. That's what I call pure oxygen. I mean, that's why innovation can be beautiful in that sense is that you get higher operating leverage, meaning ROI, natural, right? That's generally non-inflationary. So it's market friendly that can lead to higher real rates, inflation adjusted rates. So that's good for bond investors, right? Because generally adds to the risk-free rate for all asset expected returns and then clearly that can be positive for equities and companies. So that's one of the reasons why we have low growth. Yes, it's demographics, but the bigger disappointment has been productivity growth and that's worldwide, which is why some have argued this notion of stagnation. Ultimately, innovation I strongly believe will return and we have a report coming out in the next few weeks talking about the future of innovation and based upon a lot of deep research we've done. So that's encouraging. It probably won't show up in 2020, but longer term I'm less pessimistic when I look out 10 years than some, knowing that the world has challenges to be sure. You know, I think of our more muted return outlook. So ironically, there's two broad things for this because I talked to financial market reporters and they're thinking about it from the active management side or they'll say then, okay, well what's the best asset class to invest in if it's low returns? Which is not really the, I think the right way to think about it. I think what this is is all the more reason for this say the course and staying fully invested because if it's a low return environment that means that we have to have our money at work in our portfolio every day of the week, right? Because returns are lumpy and it's tough to know when the stock market will go up any day, week or month. And then secondly, that's where the planning and focusing on the cost and just the diversification I call those free lunches of the portfolio they're gonna be that much more important. Now I know that your listeners appreciate this but I think we're gonna have to, I think to be a service to others that are not, I would ask at least we turn up our volume on this a little bit because I think it may not be as important to someone of lower cost or diversification when you get a almost any portfolio it gives you 10% return. I think it matters much more to our friends and family if we're talking about expected returns of four or 5%. Because the margin for error is just lower. Much lower. So it doesn't mean we can't overcome it. It's the bond arithmetic that's really gonna, I think hurt equity markets not as shiny as it was too but that just means I think we should have to grit our teeth a little bit and focus on those fundamentals. When you talk to some, not on this podcast Rick but we talked to some, right? It doesn't sound as exciting, right?  They look at you as like, really? There's not a secret panacea on this. When you don't like the forecast you just go find a new economist. Yeah, well there's no silver bullet on that, right? There is no silver bullet. Do you have a recommended international stock allocation for your typical Boglehead investor? I mean, I would personally start any investor at 40% on non-US equity exposure. And this is something that we actually do in our advice units. It's also the default non-US equity exposure in our target date funds. That is consistent across Vanguard. And so that's where I would start. It's not a fully market cap. The non-US market is a little bit higher percentage but I think how I generally approach it is by following that 40%. You start there and then if you have less comfort or more comfort deviating from that but I think if you can start there that's that important. And because that really reduces the volatility of the portfolio. That's the so-called quote unquote if there's a sweet spot quote unquote. You have the lowest standard deviation in returns when you have that mix. The returns differentials between the US and non-US will bounce around any year they have and they will continue to. But the volatility of that portfolio is generally lowest when you're at that point. An area that you're negative on is less quality or lower quality corporate bonds. I know that your research does influence some of the more active Vanguard funds. Are they going to be taking this and shifting? I know you can't say they will do it but will they use this data to possibly shift out of an area where you're not really hot on which is the amount of triple B rated bonds that are in the corporate bond side. Yeah, well you know for those investors that have some of our actively managed bond funds and again our bond funds almost all of them are managed internally by our fixed income groups. So I have the great pleasure of sitting on the what we call the hub but it's a senior investment committee for all the actively managed bond funds. I don't chair that committee that's the head of the global head of fixed income John Hollier and several there's several of us on that committee and we take these sort of discussions that you and I are having today Rick and we take that into consideration of building the most viable and what we think is appropriate bond strategy for the investor in that fund. Now again those funds have hundreds of funds that's supported by a deep team of credit analysts and portfolio managers. Over time they add a lot of value by picking the right bond over another bond what you would call idiosyncratic risk or alpha, right? What we're primarily trying to do is just make sure that the portfolio is optimally structured so that if we like corporate bonds generally speaking because the economy doesn't look like it'll fall in recession. We're trying to pair that with interest rate diversification should we get weakness and so we would generally be say long duration you'd actually be overweight treasuries as your overweight corporate bonds and so yes this is reflected but it's not just solely like okay we think growth is higher we'll take more risks. We do this in terms of how we assess the distribution of say economic growth or inflation we always do it relative to what we assess the market is already anticipating and that's what I think is often lost by at least when you watch certain shows you read certain press reports because I think there's this assumption that I don't know higher growth or higher inflation means a direct well one should do directly something to the portfolio but I think it was lost sometimes is that the financial markets may be already pricing in a weaker or stronger than that stronger than that scenario and a great example right now is the stock market which by our calculus is already assuming GDP for 2020 will be 3% let alone two and so if one says oh we're bullish on the US economy we're two two and a half percent that may not mean that in some of these active strategies that we would modestly take more risk it's all relative to what the market is already pricing in so hopefully that's helpful it is thank you one last question because this is seems to be an emerging issue when it has to do with climate change ESG this type of a strategy are you seeing that having any effect on the market's valuations where people are putting their money I've seen clearly interest from advisors from individual investors some some institutions in particular just on environmentally you know sensitive investing you know ESG type strategies or SNRI strategies social responsible investing there's clearly more interest right now I'd say more the interest is on what is it what their fizzlers different types of those approaches right you can either screen and not own certain securities versus maybe be more proactive and owns certain companies outright so we're seeing more interest in that and we've obviously launched certain products that are consistent with those approaches time will tell how widespread they become in terms of you know investment dollars so I have heard the interest I think the academic research community starting to focus on it more in the economic space but so I'd say more to come on that something I could see us doing a little bit more deeper research going forward Joe it's been a real pleasure to have you on the Bogleheads on Investing podcast I hope we could maybe make this an annual event if Joe- That would be great, that would be great if you'll have me yeah Oh definitely Oh and I say for everyone happy new year and best of luck in 2020 This concludes the 17th episode of Bogleheads on Investing I'm your host Rick Ferry join us each month to hear a new special guest in the meantime visit Bogleheads.org and the Bogleheads Wiki participate in the forum and help others find the forum Thanks for listening


The CMOS industry in St. Lucia is riding a wave of optimism as the government continues to lend its unwavering support to its development. With an iron economic growth and sustainability, the recent donation of equipment to the Opikos CMOS Farmers Association and CMOS Farmers in Savins Bay is a tangible demonstration of the government's commitment to this burgeoning industry. Through export St. Lucia, these local farmers have received a significant boost in the form of drawing tables and flotation devices, essential tools that will help them maintain proper standards and elevate their CMOS farming operations to new heights. President of the Opikos CMOS Farmers Association, Cohen Samuel, expressed his gratitude for the donation and highlighted the importance of maintaining high standards in CMOS farming. He explains that this will not only enhance the competitiveness of St. Lucia's CMOS in the international market, but also promote sustainable farming practices among local farmers. I believe and have been pleading for the CMOS farmers in St. Lucia and for this industry, we believe that it can grow, but we need to reach the standard which we have to reach, so that our CMOS will not just be the best in the world. We know it's the best already, but anyone who comes to St. Lucia will be proud of what we have achieved through this agriculture, especially CMOS. According to Minister for Agriculture, Hon. Alfred Prosper, this recent donation is part of ongoing efforts to empower local CMOS farmers with the necessary tools and equipment to improve their farming practices and meet industry standards. He also expressed optimism about the tremendous opportunities for livelihoods through diversification in the CMOS industry. It has always been a concern to me that we need to be able to impact the livelihoods of people in rural areas and the CMOS sector is well-placed to do so. I know we all are aware of the value of our CMOS. We have been told that it's one of the best in the world. And obviously if something is one of the best in the world, we have to cherish it and be able to ensure that St. Lucia maintain that status. And that status cannot only be maintained by the government giving us a significant amount of money to boost the sector, but the stakeholders like you who are involved in the growing of the CMOS, in the processing of the CMOS also have a very significant role to play. Another role is to ensure that we produce CMOS of high quality at a consistent level. The recent donation of CMOS farming equipment to the OPCOR CMOS Farmers Association underscores the government of St. Lucia's commitment to the growth and sustainability of the CMOS industry. This support will enable local farmers to adhere to proper standards and contribute to the industry's success.

What's up everybody on the mangoos, you were awesome and today I'm bringing you my first game of paragon the overprime in the final beta test. I was playing with jelly knees and jedi and I picked my girl the fey for mid lane, however the rest of my team locked in giddy and embellica so I just swapped over to the support. Kinda. You'll see. While I did fairly well during the match, there is of course room for improvement so before we jump into it, let's take a quick look at some of the good things I did as well as some of the bad. The bad. I did a horrible job of using her Q, forest, wind, as the line of brambles as a movement speed boost. This is new to the fey and I didn't take enough advantage of it. And poor offensive placement of a right click AOE ability that's called forest will. It's hard to say that.  Wards as always. I didn't pick up the support item for warding because I thought I was going mid lane, but that's no excuse for not warding more often. Now the good things. I was flexible with my role. Remember, no matter how angry it makes you, you can't change the way your team plays. You can only change the way you play. So swapping from mid lane to support was the most helpful thing I could do. Good defensive placement of my right click. I did a pretty good job of just placing this down in front of me and then running melee characters through it and dealing damage to them while I circled around them and hitting them with the basic attacks. And here's an odd one for me. Kept my head during battles and made pretty good split second decisions on the fly. Not always, of course, but there were a few times I was kind of like, well, damn, I actually made a good decision there. With all that in mind, let's watch the game. I stopped here to let my team know that I was going to go ahead and support just so that there was no confusion over the lanes. And we're going to go ahead and provide a leash for jelly. This thing goes down pretty quick though. So I just kind of pieced out. I am playing with jelly knees. Jelly knees is our jungler, but he is down with the sickness right now. So he was unable to speak during the game. And that's what I'm talking about with poor usage of my Q. I'm treating it like it's a slow. It's not a slow anymore. It's a movement speed boost for allies. So yeah, you're going to see me do that a lot during this game. It still deals damage. So it was not completely useless. And it did give Jedi a bit of a speed boost there. So it's OK. I just did not use it all that great. I should have leveled up my right click first. That's what gives it the slow. That's the more supporting ability for the fade. I am so low. I'm backing. Actually, my pot is doing well. Jelly's coming in, I think. That's more like it. I used the flower to prevent steal from escaping and to slow sparrow. And jelly ended up rooting sparrow inside the flower. And I got first blood. I wouldn't really mean into. Wanted jelly to get that kill.  So it's all good. It's all good. You're good. Didn't know you were back. There still kept wanting to hide in the bushes. So I was throwing my whatever you call it, her R&B into the bushes to kind of dissuade him from doing that. Looking back, I probably should have thrown it into the back half of the bush. That way, Jedi could have pinged him with grenades in the front of the half of the bush. We could have that would have been a little bit more effective. So I'm going to have to remember that later on. To throw that. If I end up supporting with Faye again, to use that user R&B on the back half of the bushes when somebody's trying to hide in there. He's going into the bush on left. I don't get how harvest nettles work yet. This fall, leveled up. The skill can be in hat. He's still sitting in there.  Let's go, dude. Yeah, I didn't expect Argydian to go in like that. Or I would have moved forward a lot sooner. Argydian was actually pretty good. The Argydian and Bellica were both were pretty good. They just didn't select lanes at the beginning. I think Bellica selected jungle or something. But anyway, their skills were pretty good. They just didn't quite understand the game quite yet. We're taking the Prime Spirit, which is a very important buff to take.  I absorbed the energy of the spirits. Maybe? There we go. I got to turn this sound.  Yep, it's OK. All life steal. The enemy tower is under attack. In this situation, we've got a big minion push onto our tower. But I don't want to take the ADC's last hit. So I'm just going to start getting the siege minion low for him so that he can take it. She's up there on the right. So he's in that bush, I think, on the left. There, there, left. The enemy tower is under attack. There's probably a little greedy. But I just want to push that. I'm going to leave. All right, I'm leaving. Slight delay on when you press B. Now that my ADC went back, there's no use in letting these last hits go to waste. So I'm not going to speed farm it. I'm not just going to pelt into this minion wave over and over again. But I am going to take the last hits when they present themselves. I'm not level my ultimate. Don't know. Yeah, steal, steal over there. OK, I see it moving around in the bush. Got my ultimate. OK, let me know if you want to use it. I think that's a lock one. That's insane if that is a lock one. On the right, on the right. Oh, what? OK, whew. I barely got out. I'm leaving. We survived the jungle gank. Good job, gank. Yeah, I don't know how low they are for you, Jelly, but did you get another one? Yeah, still might be in that bush, Jelly. There he is. Let's go. Let's go. Nice, nice, nice. Going berserk, huh? All right. He is going berserk, that jelly knees. I'm old. This skill can be enhanced. Take this buff. Let me finish pushing this, and then I'll take it. Or if you get it before we move on. I'm on line. Oh, you got it. All right. I needed the mana anyway. That's fair.  That was a horrible use of my ultimate. Not only did I steal a kill, but I also didn't have it up to save Jedi from the rampage right there. Nice job, boys. I'm just cleaning minions. I'm low. Watch out. Up above, on the right. He's in that bush, Jelly. I'm on my way. He bucked it up. Let's go, boys. Nice, nice, nice. Woo. Let's go. I didn't even know you took that. He's focusing me. Got him. Now, that situation, I don't feel so bad about stealing that kill. Jedi was really low. I had no idea when Steel's bull rush was going to come off cooldown, so I just wanted to make sure that Jedi didn't die.  I absorbed the energy of his spirits. I'm coming. I'm rotating behind him. I'm trying to come. Oh, yeah, I've got sprint mode. Fuck, I forgot about sprinting. Let's go. Nice. Now, I'm going to back. Oh, that looks sick, Jelly.   Mm-hmm. Ha, ha, ha. You got that, Jelly? Been defeated by an ally. Sorry, Jelly. I'm going to drop this thing once we get up here. I decided to right there to drop the prime guardian mid fight because I figured it's more important that they don't get it, that I live. Fortunately, Sparrow ends up, well, unfortunately, for Jedi. But fortunately for me, Sparrow ended up focusing Jedi instead of me, so I didn't die. Well, now while I'm fighting this quang, it's a good example of how to use your R&B. Poor example of how to use your Q. I could have been using my Q to speed boost myself out of there. I was trying to use it to slow him. It doesn't freaking slow. I can't get that through my head. Get out, let's go.  Dude, Econ feels really good, too. Like the amount of money that I'm making? Yeah.  My screen went black in the middle of that for some reason. Oh, did you accidentally hold tab or anything? No, my screen does that sometimes. I need a new monitor.  Their Sparrow is actually decent, at least strong. I thought for sure I could 1v1 her. I was wrong.  Rampage somewhere. I think I chose the long way around, no matter. That rampage is fucked, yeah. All right, mid lane. I won it. OK, me and Jelliers fighting this.  There we go. We're on our way. The ally absorbed the energy of his spirit. Oh, Gideon's still going in. The ally towers.   I couldn't use my, oh, fucking, I was using the wrong button. I was trying to blink, and I couldn't. Either way, we struggled to get it to go past the point. I'm also coming. I think everybody's coming. Wait, where did I end up? Oh, I'm so far away. Still going, though. Might be coming from behind him. Back up, maybe there's a barrier. I'm here. He used his blink. He went up in lane. Yep, you got him. Nice job, dude. OK, get away from this. Seemed like it gets frozen in the same spot that it used to, like just outside of the turret, which makes me think that you can't set up a freeze or set up a slow push. They're, like, off the lane. Sparrow's coming, Jelly. I'm coming in behind. Howitzer's coming in, too. Oh, they engaged prime. I thought I was going to get that re-page. God, dude, I get just chunked out there. You want to go on? OK. Worried about my health, but. Everything I got. Defeated by it. Backing. Yes, I'm here. One more way to get, Jelly.  Nice. Nice job, guys. Behind, behind. Two, pushing the lane, Jelly. Very clever use of the bellica drone to absorb inhibitor shots so that the minions can deal more damage to the inhib. Much respect to the bellica. Inhibitor, destroy. The LR Super Tier is spawning in the lane. OK, I'm going to see a big problem I have with the game.  I can see, like, on the sides up next to the inhibitors.  Oh, I can't get through this wall. Ha, ha, ha. Ha, ha, ha, that was my dumbass mistake. I thought I could run through that wall and I couldn't. You know, it's not kitty cuddle time right now, sweetie. Oh, I just ran into that everybody. We just won. OK, cool. I was over there fighting in the jungle. Gee, geez, boys.  I played support and still mash you and kills Jelly. Ha, ha, ha, ha. Nowhere near you on damage dealt. Jungle tea on the side of the cherry. And that's it for today, guys. I hope you enjoyed it.  So there's going to be plenty more videos to come with plenty more different characters. So I like the video if you enjoyed it. Sub for more third person mobile content.

In this paper, the effects of nonlinear thermal radiation and chemical reaction on MHD-Casin nanofluid flow over a porous stretching slash shrinking surface were studied. The governing equations were transformed using similarity transformations and then solved numerically using Chebyshev spectral collocation methods. The results showed that the velocity, temperature, concentration, entropy profiles, and local Nusselt and Sherwood numbers all depended on the various parameters of interest. Additionally, the results were compared to those obtained in previous studies. This article was authored by Jiaqin, Muhammad Mubashir Bhatti, Minawar Ali Abbas, and others.
