Theta tells you how much the price of an option should decrease each day as the option nears expiration, if all other factors remain the same. This kind of price erosion over time is known as time decay. Time-value erosion is not linear, meaning the price erosion of at-the-money (ATM)...
How Time Decay Works Time decay is the reduction in the value of an option as the time to the expiration date approaches. An option's time value is how much time plays into the value—or the premium—for the option. The time value declines or time decay accelerates as the expiration ...

Time spreads are used to profit from the difference in time decay between options with different expiry dates. Traders buy a longer-dated option and sell a shorter-dated option at the same strike price. This form of arbitrage enables traders to benefit from faster time decay of shorter-dated ...
Theta quantifies how much value is lost on the option due to the passing of time, known as time decay. Theta is typically negative for purchased calls and puts, and positive for sold calls and puts. If XYZ were trading at $50, and a 50 strike call with 150 days until expiration had...
Social interactions between hosts and the area of transmission \(A_x\) will influence \(\rho (x,s)\). Using equation 2, we can now ask: how much does the term \(\sigma _i(x) \sigma _j(x) \int _{0}^{\infty } \rho (x, s) \Theta (s) ds\) contribute to FOI for ...
In options, Thetameasures the time decay of the trading contract.Options contracts lose time value as they come close to the expiry time — and Theta provides a means for traders to understand just how much value is being lost as this occurs. In most cases, Theta is shown with negative nu...
