Options may be sold and resold many different times before their expiry, as most traders don’t actually exercise them. Many options traders buy options at one premium with the hope of reselling them for a higher premium later on based on price changes in the underlying asset. An example is portrayed below, indicating the potential payoff for a call option on RBC stock, with an option premium of $10 and a strike price of $100.
