Delta Hedging Mechanics
Delta hedging is a strategy used by option traders to reduce or eliminate the risk associated with price movements of the underlying asset. The delta of an option measures how much the option price is expected to change for a one-unit change in the underlying asset price.
By holding a position in the underlying asset that offsets the option's delta, the trader becomes delta-neutral, meaning the portfolio value is no longer sensitive to small price changes. In the volatile world of crypto options, market makers must constantly rebalance their hedges as the delta changes with price and time.
This constant buying and selling of the underlying asset to maintain neutrality is a major source of market volatility. It is a core quantitative finance concept that bridges the gap between derivative pricing and spot market dynamics.
