### Comment:
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?

### REPLY:
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?
