How a long call works

A long call gives its holder the right to buy the underlying at the strike price through expiration. Its potential gain increases as the stock rises, while the premium paid is the maximum loss if the call expires worthless.

Price, volatility, and time

A higher underlying price or implied-volatility assumption generally increases a call's theoretical value. Time decay works in the opposite direction, reducing remaining time value as expiration approaches.
