- Delta. Delta measures how much an option's price can be expected to move for every $1 change in the price of the underlying security or index. For example, a Delta of 0.40 means the option's price will theoretically move $0.40 for every $1 change in the price of the underlying stock or index.
- Gamma. Where Delta is a snapshot in time, Gamma measures the rate of change in an option's Delta over time. If you remember high school physics class, you can think of Delta as speed and Gamma as acceleration.
- Theta. Theta tells you how much the price of an option should decrease each day as the option nears expiration, if all other factors remain the same. This kind of price erosion over time is known as time decay.

- Vega. Vega measures how much an option’s price should change when the underlying stock’s volatility changes. It can be used to gauge an option’s sensitivity to volatility.
