## Delta Decay Risk

Delta decay risk refers to the potential for an option's delta to change unexpectedly due to factors like time decay, volatility shifts, or large underlying price movements. As an option approaches expiration, its delta becomes more sensitive to changes in the underlying price, a phenomenon known as gamma risk.

If a trader does not account for this, their hedge can quickly become ineffective, leading to significant losses. Delta decay risk is particularly acute for market makers who hold large portfolios of options and must constantly rebalance their hedges.

Effective risk management requires monitoring these Greeks and adjusting positions proactively. It is a constant challenge in maintaining a delta-neutral portfolio.

Understanding how delta evolves over time is essential for successful options trading.
