If you do not sell (or "close") a put option you own before expiration, its value will depend on whether it is in-the-money (stock price is below the strike price). In-the-money puts are typically exercised automatically, allowing you to sell the underlying stock at the strike price, while out-of-the-money puts expire worthless.

What happens if you don't sell your put option?

An option's expiration date is the last day you can exercise your right to buy or sell the underlying stock at the agreed-upon strike price. If you hold your contract until expiration, and it is either out-of-the-money or in-the-money but you choose to not exercise it, the option will expire worthless.

Are you obligated to sell a put option?

What happens if a put option is not sold before expiry?

What is the 7% sell rule?

The 7% sell rule is a stock trading guideline to cut losses quickly, advising you to sell a stock if it drops 7-8% below your purchase price to protect capital, remove emotion, and prevent small losses from becoming catastrophic, a strategy popularized by William O'Neil's CAN SLIM method for growth investing. It assumes that truly strong stocks typically don't fall much below their buy point, so a dip signals something is wrong, requiring you to exit the trade to preserve funds for better opportunities.

What is the 60/40 rule for options?

The "60/40 tax rule" (IRS Section 1256) is a favorable tax treatment for certain derivatives, meaning 60% of profits/losses are taxed as long-term capital gains (lower rates) and 40% as short-term (higher rates), regardless of holding period, applying to futures, non-equity options (like index options), and certain other contracts, offering significant tax savings compared to standard equity options. Options for traders include using this treatment on broad-based index options or futures, potentially electing Section 475 for Mark-to-Market (MTM) treatment on securities (while retaining 1256 for futures), and consulting a tax specialist to align strategies with tax efficiency.
