Options Greeks

Delta

Delta measures the sensitivity of an option’s price to changes in the underlying asset’s price, representing the directional exposure of the option position. A Delta of 0.5 indicates that the option price will move approximately 50 cents for every dollar change in the underlying asset. For quantitative traders, Delta is crucial for calculating the hedge ratio required to maintain a market-neutral position. In cryptocurrency options, Delta changes rapidly as the underlying asset moves, requiring dynamic rebalancing.
