Why would you even look back 4 years? That data is not relevant today. But, there are many metrics that go into a volatility index. Mostly, Stock go up, volatility goes down. Stocks go down, volatility goes up. What have stocks done the last four years?

That is true, stocks have perpetually increased since. However volatility should be measuring the amount that the stocks can go up or down in a given time period, so why does it increase when stocks decrease? Doesn't that imply a correlation between stock price and volatility, when volatility is meant to be a measure of the potential of the amount that a stock could change?
