Option skew trading strategies
Skew looks at the difference between the IV for in-the-money, out-of-the-money, and at-the-money options. Implied volatility can be explained as the uncertainty related to an option's underlying stock, and the changes triggered at different options' trading prices. IV is the prevalent market view of the chance that the underlying asset will reach a given price. In-, at, and out-of-the-money refers to the strike price of an options contract as it relates to the going market price for that asset. Volatility skew is important to watch if you buy and sell options because the implied volatility rises as the uncertainty around its underlying stock increases. When options first traded on an exchange, volatility skew was very different.
A Volatility Skew Based Trading Strategy

In other words, the implied volatility for both puts and calls increased as the strike price moved away from the current stock price—leading to a " volatility smile " that can be witnessed when charting the price data.
However, after the stock market crash in October , something unusual happened to option prices. There is no need to conduct extensive research to understand the reason for this phenomenon. Because there were fewer sellers than buyers for both OTM puts and calls, they traded at higher than "normal" prices—as is true in all aspects of trading i. In addition, these puts became attractive as portfolio insurance against the next market debacle.
As a result, the "volatility smile" has been replaced with the "volatility skew". This remains true, even as the market climbs to all-time highs. That plot of strike vs. IV illustrates a volatility skew. IV is the same for a paired put and call. When the strike price and expiration are identical, then the call and put options share a common IV. That results in continued demand for puts. The following relationship exists: IV rises when markets decline; IV falls when markets rally.

The theory behind "trading the skew" is that you are getting a theoretical advantage by essentially buying and selling options on the same entity the underlying , yet these options have different volatility projections for that single underlying.
Options are heavily priced off the expected volatility of the underlying asset. Options of the same maturity would normally be expected to have the same implied volatility irrespective of the strike price.
