Strategy in a nutshell

The strategy applies dispersion trading on the S&P 500 by dynamically combining straddles. It selectively goes long on cheap single-name options and shorts index options, exploiting volatility mispricing for profit.

Economic rationale

The approach relies on the frequent overpricing of index options relative to individual stock options. By targeting volatility differences between implied and realized levels, the strategy captures excess returns while remaining market neutral.
