What Is a Protective Put Strategy?
A protective put (also known as a married put) is an options strategy where an investor who owns shares of a stock purchases a put option on the same stock to limit downside risk. The put option acts as an insurance policy — if the stock price falls below the put's strike price, the put increases in value, offsetting losses on the stock position. The cost of this protection is the premium paid for the put option.
This strategy is ideal for investors who are bullish on a stock but want to protect against unexpected downside moves. The maximum loss is limited to the difference between the current stock price and the strike price, plus the premium paid. Meanwhile, the upside potential remains unlimited (minus the premium cost). Our free Protective Put Optimizer helps you analyze every available put option to find the best balance between cost and protection.

Important Considerations
- Cost of Protection: Protective puts require paying a premium, which reduces your overall return if the stock price stays flat or rises. Think of it as paying for insurance — the premium is the cost of peace of mind.
- Time Decay (Theta): Put options lose value over time due to theta decay. The closer to expiration, the faster the time value erodes. Consider this when choosing your protection period — longer-dated puts decay more slowly.
- Strike Selection: Out-of-the-money (OTM) puts are cheaper but only protect against larger declines. At-the-money (ATM) puts provide immediate protection but cost more. In-the-money (ITM) puts offer the most protection but at the highest premium.
- Implied Volatility: Higher IV means more expensive puts. If you expect volatility to decrease, the put's value may decline even if the stock drops slightly. Monitor IV levels relative to historical norms before purchasing protection.
