How is skew measured for the stock markets? Since skew is used to measure the expectations around the market direction, it is calculated as the difference between implied volatilities of OTM put options and OTM call options of Nifty Kostenlose Lieferung möglic In fact, even your VIX dynamics are not exact, since you can only obtain dynamics for an approximation of the actual VIX calculation (I presume you are just running the variance variable through a square root using Ito's rule). SKEW is even less tractable here since its calculation roughly goes as the third moment of the return distribution SKEW Calculation. SKEW is derived from the price of S&P 500 skewness.
