The research presented on the show leveraged internal tastytrade backtests that utilized historical data in SPY and the Skew Index. Basically, the analysis sought to better understand whether a short put in SPY performed better when sold in "all environments" or when the Skew Index was elevated. According to that research, trade performance improved when the Skew Index was above 135. For the sake of reference, the Skew Index typically ranges between roughly 100 and 150, as shown below: The mathematical calculation of SKEW can be found here: SKEW Index calculation The SKEW Index typically ranges from 100 to 150, with a historical average of approximately 115. The higher the SKEW index rating, the higher the perceived tail risk and chance of a significant move.

Delta skew data is used to generate the skew index metrics: for example, SKEW90 represents the (IV of 25 delta put – IV of 25 delta call)/ (50 delta call IV) for virtual options expiring in 90 days. In probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can be positive, zero, negative, or undefined. For a unimodal distribution, negative skew commonly indicates that the tail is on the left side of the distribution, and positive skew indicates that the tail is on the right.
