SPX'S GEX is printing high numbers !

Gamma exposure (GEX); refers to the sensitivity of existing option contracts to changes in the underlying price. Like with DPI, substantial imbalances can occur between market-makers' call- and put-option exposures, and when those imbalances occur, the effect of their hedges can either accelerate price swings (like a squeeze) or stifle movement entirely.
