Eh, this is kind of a thing of the past as far as most people are concerned. 

Like yeah 8/10 of the worst days in stock market history are March or October, but 7/10 are specifically October and I'm pretty sure 6 are just part of either 2008 or the Great Depression which are ~70 years apart. 2 events make up ~60% of these days and are drawn out events. 

zThe October Effect is an anomaly at best in my opinion.

Not saying you’re wrong here, but one interesting counter point to this was the government knowing they were going to shut down the economy for Covid three weeks before they actually pulled to the trigger to get past the March Options cycle. 

To your point, there are soooo many different “investment vehicles” these days and FTD’s don’t seem to mean shit anymore….so I could also agree with you at the same time.
