What causes IV to spike?
IV typically gets high when the company has news or some event impending that could move the stock – I call it the event horizon – and I refer to this kind of volatility as event volatility. These stocks sometimes are called “situation” stocks.
Why is IV higher for OTM options?
The closer an option is to expiring, the more volatility is needed to reach OTM strike prices. That means the IV increases because the underlying stock would need to move farther and faster to hit the OTM strike price before the expiration.
Is VIX same as implied volatility?
Specifically, VIX measures the implied volatility of the S&P 500® (SPX) for the next 30 days. When implied volatility is high, the VIX level is high and the range of likely values is broad. When implied volatility is low, the VIX level is low and the range is narrow.
How do you profit from volatility skew?
Now, Use A Ratio Spread To Profit From Skew
Start buying options with lower implied volatility while selling options with higher implied volatility. If you then offset the sales of options by 2:1 to the purchases you will exploit the negative skew in the IWM put options.
How do you buy skew?
Traders who “trade the skew” generally use a spread-buying the cheaper (lower implied volatility) options and selling the expensive (higher implied volatility) ones. They are looking for the implied volatilities of the options involved in the spread to converge at or before expiration.
Why are OTM options more volatile?
