## Theta Decay Impact

Theta decay, or time decay, represents the erosion of an option's value as it approaches its expiration date. Since options have a finite lifespan, the extrinsic value of the contract decreases daily, all else being equal.

This decay is non-linear, accelerating significantly as the expiration date draws closer, particularly for at-the-money options. For traders holding long options, theta decay is a cost that must be offset by favorable price movements.

For sellers, it is a source of revenue. Managing this impact is vital for hedgers, as they must balance the cost of holding options against the risk-mitigation benefits they provide over time.
