Is the VIX predictable?

1 170
I read an article the other day claiming "The VIX is Very Predictable"

It claimed the method to buy/sell "the VIX" (which itself can't be bought or sold) is to take the 11 day ema and sma, plot them and buy when the ema goes under the sma, and sell when the ema goes above the sma.

Here is a chart of the vix and a little indicator that I coded up using the method described. The red line is the ema and the white is the sma. I colored the background "green = buy" and "red = sell".

Seems there needs to be a bit of refinement for this method to work ... but it's a start. Would welcome other ideas in the comments.
