About this listen
Gamma is one of the most misunderstood yet powerful forces driving options markets. In this episode, Kirk sits down with Lex from Tradier to break down gamma exposure (GEX) — what it is, why it matters, and how it quietly shapes market movement.
Together, they unpack how professional traders use gamma to stay delta-neutral, manage risk, and interpret shifting liquidity, while retail traders can use it to better understand price behavior and volatility.
Lex explains the difference between long and short gamma, how “sticky strikes” form, and why SPX tends to act very differently from fast-moving names like GME. You’ll also learn how changes in open interest and volume can trigger sharp accelerations or reversals — and how to read these setups without getting buried in formulas. It’s a practical, eye-opening conversation about the hidden dynamics of gamma exposure and the edge it can give you in any options market.
