Definition§
Delta (Δ) is a financial metric that measures the sensitivity of the price of a derivative, such as an options contract, to a change in the price of its underlying asset. Specifically, it estimates the change in the derivative’s price given a $1 change in the price of the underlying asset. Delta values range from 0 to 1 for call options and from -1 to 0 for put options.
