Stock price when the opinion was issued
It's another indicator that tells us about nervousness by sensing volatility. If you own the VIX, this is probably a really good time to sell. It's right at the peak that we saw last August.
It's a background thing, not a way to perfect timing. Tells you the neighbourhood you're in, but doesn't tell you what to do. You can look at these moves in terms of standard deviations, and how far away from the average we are. Moves of 2 or 3 don't sound big, but they're actually quite big in terms of deviation from the average.
How do you trade it? You have to get it perfect or you don’t make a lot of money on these things.
