A long put is another simple option strategy, and involves buying (going long) a put option. Long puts are generally used by traders speculatively who believe that the underlying asset will decrease in value.
Remember: Owning a put option gives you the right to sell 100 shares of the underlying investment at the strike price, anytime before the end of the expiration date. After the expiration date, an out of the money put expires worthless.
Many traders who buy puts and use this strategy, especially in registered accounts, will never exercise their rights to sell. Because you cannot short sell shares in a registered account, if you do not own the corresponding 100 shares per put contract, you cannot exercise your contract.
Traders who own the corresponding shares of the underlying asset are said to be using a Married Put strategy, which is explained in more detail below.
Most traders using long puts speculatively in registered accounts do not exercise their option, but rather sell the option contract back into the open market.
For example: If you own a put option with a strike price of $20 with a few days until expiration, and the stock is trading at $15, you could choose to sell the option back into the market for the intrinsic value of $5 (20-15) plus any minimal time value left.
