### 8.1 – Gamma of an Option

The Gamma of an option measures this change in delta for the given change in the underlying. In other words, the Gamma of an option helps us answer this question – “For a given change in the underlying, what will be the corresponding change in the delta of the option?”

### Key takeaways from this chapter

1. Financial derivatives are called Financial derivatives because of their dependence on calculus and differential equations (generally called Derivatives)
2. Delta of an option is a variable and changes for every change in the underlying and premium

4. Delta is the 1st order derivative of premium
5. Gamma is the 2nd order derivative of premium
6. Gamma measures the rate of change of delta.
