Forget The VIX: SKEW Tells The True Story About Hedging Market Risk

Once again retail is getting duped into believing that all is well in the market by daily blasts of just how low the VIX has plunged. And it has: it is down to levels not seen in years. But as everyone who has done even a little work in option vol, the only index that matters these days, at least for equities now that precious metals and certain currencies (CHF) are the true flight to safety, is the SKEW. As we have disclosed many times in the past, SKEW is how the pros play vol, while VIX is what is left for the peasantry and CNBC. Basically, VIX shows riskiness as implied by ATM options, while SKEW demonstrates the difference between ATM and OTM options. And as the chart below shows, there is a rather dramatic difference when looking between the VIX and SKEW indices. In essence what is happening is that everyone is selling ATM short-dated vol and buying mid-term Out of the Money vol as expressed by the SKEW, in a confirmation that the protection cost in the wings is actually much higher than one would assume.




The CS Fear Barometer measures investor sentiment for 3-month investment horizons by pricing a zero-cost collar. The collar is implemented by the selling of a 10% OTM SPX call option and using the proceeds to buy an OTM put. The CSFB level represents how far out-of-the-money that SPX put is. The higher the level, the greater the fear."
