Nov 17, 2019 · I would like to understand why the Black and Scholes greek letter theta for european call option behave in the following way: as time to maturity is far away (right part of the x-axis in the the graph) theta is small for all the call options (ATM, ITM e OTM). Therefore this means that the call value decrease by a small amount as time passes when time to maturity is far away.

17.11.2019 · Hence, every day matters a lot for the value of options with short time to maturity. You have a lot of time value decay and hence, a large theta. Note that the Black Scholes model assumes continuous sample paths, so you can't argue with the possibility of sudden news occurring days before the expiration.

Black-Scholes model were correct then we should have a at implied volatility surface. The volatility surface is a function of strike, K, and time-to-maturity, T, and is de ned implicitly C(S;K;T) := BS(S;T;r;q;K;˙(K;T))(14) where C(S;K;T) denotes the current market price of a call option with time-to-maturity Tand strike K, and
