What is Put Option?

Definition

A put option gives the buyer the right to sell the underlying asset at the strike price before expiration. Puts are used when an investor expects the price to fall or wants to protect against downside risk in existing holdings.

Detailed Explanation

Put options gain value as the underlying stock declines. A $100 strike put purchased for $5 breaks even at $95. Below $95, every dollar of decline is profit, up to a maximum of $95 (if the stock goes to $0).

Puts serve two primary purposes: speculation on downside moves and portfolio insurance. Buying puts as protection (protective puts) sets a price floor for owned shares, functioning like insurance. The premium is the cost of that insurance.

Put options can be used instead of short selling. Buying a put gives bearish exposure with a known maximum loss (the premium), unlike short selling where losses are theoretically unlimited. This defined-risk characteristic makes puts attractive for bearish bets.

Selling puts is a strategy used by investors willing to buy a stock at a lower price. By selling a put at a strike below the current price, you collect premium income. If the stock declines below the strike, you are obligated to buy at that price, which you were willing to do anyway.

Frequently Asked Questions

How do puts protect my portfolio?

Buying puts on stocks you own (protective puts) guarantees you can sell at the strike price regardless of how far the stock falls. It creates a price floor, limiting your maximum loss to the difference between your cost and the strike price, plus the premium.

What is a cash-secured put?

Selling a put while holding enough cash to buy the shares if assigned. You earn the premium and are obligated to buy the stock at the strike price if it falls below that level. It is used to potentially buy stocks at a discount.

When does buying puts make sense?

When you are bearish and want defined-risk exposure, when you want to hedge existing positions, or when you believe a stock will decline significantly before the option expires. Consider time decay and implied volatility costs.
