How this works
P/L at expiration = (intrinsic value − premium) × 100 × contracts for a long position; the sign flips for a short. Intrinsic value is max(0, price − strike) for a call and max(0, strike − price) for a put.
A long call's upside is unbounded; a short (naked) call's loss is unbounded. Everything here is the value at expiration only - before expiration, time value and implied volatility change the price.
