SPX (S&P 500 Index) Options Market Gamma Model Output
How Does Stock Market Options Gamma Work?
Gamma is an options measurement which estimates the amount of hedging required for a given move in the underlying stock or index. SpotGamma downloads all of the open interest for the S&P500 (SPX, SPY) and uses an algorithm to estimate how much options dealers (market makers, banks, dealers, etc) will have to hedge for a given move in the SPX. More importantly, the gamma market model output helps forecast how the dealers are currently positioned and might react to a given move in the SPX. See here for an example. Having an idea of the size and direction options dealers hedge is a powerful metric to use for your own trading. Here’s why.
