What is option GAMMA?
If Delta is viewed as the ‘speed’ of price movement of option relative to underlying then option Gamma can be viewed as the acceleration. Basically, Gamma measures the amount by which delta changes for a 1 point change in the stock price. For example, if Gamma of an option is 0.5, that means theoretically that with 1 point price movement of underlying the delta will move 0.5. Long calls and long puts have positive gamma whereas short calls and short puts have negative gamma.
