An investor purchases a put option on a stock that is currently priced at $50 per share. The put option allows the investor to sell 100 shares at $45 per share anytime within the next three months. If the market price of the stock falls below $45, the investor can exercise the put option to sell the shares at the higher strike price of $45, thereby potentially mitigating losses or even realizing a gain.
