What happens to a put option if the stock price falls?

If the stock declines below the strike price, the put option is considered to be “in the money.” An in-the-money put option has "intrinsic value" because the market price of the stock is lower than the strike price. The buyer has two choices: First, if the buyer owns the stock, the put option contract can be exercised, putting the stock to the put seller at the strike price. This illustrates the "protective" put because even if the stock's market price falls, the put buyer can still sell the shares at the higher strike price instead of the lower market price. Second, the buyer can sell the put before expiration in order to capture the value, without having to sell any underlying stock.
