What is a protective put?

Direct answer

A protective put combines owned shares with a purchased put. The put gives its holder the right to sell the shares at the strike price through expiration, creating a defined floor for the stock position before the put's cost. The shares can still rise, but the option premium is paid upfront and its time value can decline as expiration approaches

The put supplies a right to sell

The shares remain exposed to price changes, while the purchased put gives the holder a right to sell at its strike price. At expiration, a lower stock price can increase the put's value and offset part of the decline in the shares

Protection has a cost and an end date

The premium paid for the put reduces the position's result whether or not the stock falls. The protection applies only through the option's expiration, so the remaining time and chosen strike are essential parts of the position rather than implementation details

The stock's upside remains open

Unlike a covered call, a protective put does not set an upper cap on the shares' value. But a rising stock does not guarantee the put premium is recovered; the combined outcome depends on the stock move, the option price paid, and the time remaining

What to remember

  1. The long put can limit the stock position's downside through expiration
  2. The option premium is a known cost, even if the put finishes without value
  3. The strike and expiration define the protection rather than a permanent floor
