In other words, a surprising increase in realized volatility may not be too far away. Below is a chart showing the current SKEW/VIX...
Always checking the the Joe Sixpack risk indicator VIX vs the Pro's SKEW....especially when SKEW is >140 and VIX diverging lower its an indication to be very cautious....all looks good now
Similar to VIX, the price of S&P 500 tail risk is calculated from the prices of S&P 500 out-of-the-money options. SKEW typically ranges from 100 to 150. A SKEW value of 100 means that the perceived distribution of S&P 500 log-returns is normal, and the probability of outlier returns is therefore negligible. As SKEW rises above 100, the left tail of the S&P 500...
