Delta in derivatives trading measures how much an option or derivative price changes when the underlying price changes.
Delta (\(\Delta\)) is a fundamental concept in the realm of financial derivatives. It is a ratio that measures the sensitivity of a derivative’s price to the changes in the price of its underlying asset. Specifically, Delta quantifies the change in the price of an option (or other derivative) for a one-unit change in the price of the underlying asset.
Mathematically, Delta (\(\Delta\)) is represented as:
Consider a call option with a delta of 0.5. If the price of the underlying stock increases by $1, the price of the call option is expected to increase by $0.50.
Call options generally have a positive delta, meaning their value increases as the underlying asset’s price increases.
Put options usually possess a negative delta, indicating their value increases as the underlying asset’s price decreases.
Delta is utilized in various trading strategies, such as:
