## Cboe skew index methodology

A Theory of the CBOE SKEW Abstract The CBOE SKEW is a new index launched by the Chicago Board Options Ex-change (CBOE) in February 2011. Its term structure tracks risk-neutral skewness of the S&P 500 (SPX) index for diﬀerent maturities. In this paper, we develop a theory for the CBOE SKEW by modelling SPX using a jump-diﬀusion process with stochas- The metric about which we hear most often within the financial media is the “Volatility Index” – quite often referred to as a “Fear Index”. It is in this context that, with all due respect to the financial media, I suggest that the CBOE SKEW Index is a more effective and helpful metric through which to track either risk or fear. The CBOE Skew IndexSM or "SKEW" – is an option-based indicator that measures the perceived tail risk of the distribution of S&P 500 log returns at a 30- day horizon. CBOE Skew Interpretation The CBOE Skew Index works as a measure of panic, in the Equity Markets. The CBOE SKEW Index (SKEW) is essentially the relationship between the implied volatility of S&P 500 Index (SPX) out-of-the-money (OOTM) puts to comparable OOTM calls. The higher the number, the higher the SKEW -- that is to say, the higher relative premium investors/traders are willing to pay to hedge against tail risk.

The observable public information of the SKEW could be useful in forecasting future stock returns, even market crashes. When the Skew index rises its an indicator of fear within the stock markets. Usually when the Skew hits $150 or higher investors should be very leary on what is to come. I fear a steep decline is coming very soon. Skew Index is a must in anyones watchlist right next to the VIX. Hope this finds you well.

## The VVIX measures the volatility of the VIX, or the volatility of volatility; the ratio of the CBOE VVIX Index to the VIX Index can be considered a useful measure to gauge a change in volatility regimes whenever historical highs or lows are reached.

It is calculated and disseminated on a real-time basis by the Chicago Board Options Exchange (CBOE), and is commonly referred to as the fear index or the fear gauge. Cboe Global Markets revolutionized investing with the creation of the Cboe Volatility Index® (VIX® Index), the first benchmark index to measure the market’s expectation of future volatility. The VIX Index is based on options of the S&P 500® Index, considered the leading indicator of the broad U.S. stock market. The VVIX measures the volatility of the VIX, or the volatility of volatility; the ratio of the CBOE VVIX Index to the VIX Index can be considered a useful measure to gauge a change in volatility regimes whenever historical highs or lows are reached.
