Derivatives & Options Beginner

Time decay

The steady loss of an option's extrinsic value as expiration approaches, measured by theta. It works against buyers and for sellers, and it accelerates non-linearly in the final weeks. Choosing the right expiry is fundamentally a decision about how much time decay you are willing to pay for or collect.
