Protective Puts: How to Put a Floor Under a Stock Position and What It Costs in 2026
October 24, 2026
14 min read
A protective put is a put option bought to protect shares you already own. If the stock falls below the put's strike price, the put gains value and sets a floor under the position. If the stock rises, you keep the upside, minus what the put cost. That is the whole idea, and it is why traders compare a protective put to insurance: you pay a known premium up front so that a bad outcome has a known limit.
The trouble is that insurance is never free, and it is easy to buy the wrong policy. Traders pick a strike without working out where the floor really sits, pay for protection that expires before the risk they were worried about, or treat a protective put as a hedge that removes all loss. It does not. It limits loss to a number you can calculate before you buy, and that number includes the premium.
In this guide we'll cover what a protective put is and how its payoff works, how to calculate the floor, the breakeven and the cost, how to choose a strike and an expiration, how a protective put compares with a stop order and other ways of limiting risk, and what all of this means inside a simulated funded options account, where you trade calls and puts but do not hold shares.
Key Takeaways
- Calculate the floor before you buy. Your maximum loss is the stock price minus the strike price, plus the premium you paid. Write that dollar figure down first.
- Treat the premium as a cost, not a deposit. If the stock never falls, the put can expire worthless, and the premium raises the price the stock must reach before you profit.
- Match the expiration to the risk. Protection that expires before the event you are worried about is not protection.
- Choose the strike by the loss you can accept. A strike near the stock price costs more and protects sooner. A lower strike is cheaper and leaves a bigger gap before it starts working.
- Learn the logic even where you cannot build the position. TradeFundrr options accounts trade calls and puts, not shares, so the classic protective put lives on as the long leg of a defined-risk spread.

What is a protective put?
A protective put is a long put option held alongside a long stock position, usually one put for every 100 shares. The put gives you the right to sell the shares at the strike price until the option expires, so it caps how much the position can lose while leaving the upside open.
The two parts of the position
The first part is the stock. You own it because you expect it to rise or because you want to keep holding it. The second part is the put. A put option gives its buyer the right, but not the obligation, to sell the underlying at a fixed price, the strike, before a set date. The SEC's Investor Bulletin on options explains that an option contract generally represents 100 shares and that the premium is paid up front to the seller of the contract and is not refundable.
Put the two together and you have a position that behaves differently from stock alone. Above the strike, it moves with the stock, a little behind because of the premium. Below the strike, the put gains roughly what the stock loses, so the combined position stops falling.
If you want a refresher on how puts work on their own before adding shares, our guide to calls vs puts covers rights, obligations and payoff shapes from the beginning.
Why traders call it insurance
The Options Industry Council, the education arm of the Options Clearing Corporation, describes the protective put as a hedge against a temporary dip in a stock's value, and compares it to homeowner's insurance. You pay a premium for protection you hope you never use. If the stock rises, the put may expire worthless, just as a year without a house fire means the insurance premium bought nothing you can point to.
Protective put vs married put
The OIC notes that the married put and the protective put are the same structure. The only difference is timing. A protective put is bought to hedge shares you already hold. A married put is bought at the same time as the shares. The payoff at expiration is identical either way.
The OIC's strategy page also describes the outlook behind the trade: the investor is bullish overall but worried about a sharp temporary decline. That outlook matters. A trader who is bearish on the stock for the long term usually has better choices than paying for insurance on shares they do not really want to own.
How to calculate a protective put's floor, breakeven and cost
Three numbers describe any protective put: the maximum loss, the breakeven and the cost. The maximum loss is the stock purchase price minus the strike price, plus the premium. The breakeven at expiration is the stock purchase price plus the premium. The cost is the premium times 100 for each contract.
A worked example
Illustrative example: a trader owns 100 shares bought at $50. Worried about a drop over the next month, they buy one 48-strike put for $1.20 per share. The put costs $120, because one contract covers 100 shares.
- Maximum loss: ($50 minus $48) plus $1.20 equals $3.20 per share, or $320 for the position. It does not matter how far the stock falls below $48. The put covers everything under the strike.
- Breakeven at expiration: $50 plus $1.20 equals $51.20. The stock has to climb above $51.20 for the combined position to show a profit at expiration.
- Upside: open. If the stock reaches $60, the shares are up $1,000, the put expires worthless, and the position is up $880.
Compare that with the shares alone. At $40 the unprotected position is down $1,000. The protected position is down $320. That $680 difference is what the $120 premium bought. At $60 the unprotected position is up $1,000 and the protected one is up $880. That $120 difference is what the protection cost in a month when it was not needed.

Before you buy
- 1Name the risk and the date. An earnings report, a product decision, a market event. The put has to outlast it.
- 2Pick the loss you can accept. That sets the strike. A lower strike is cheaper and protects later.
- 3Price the protection. Compare the premium with what a stop order or a smaller position would give you.
- 4Plan the exit. Sell the put back, hold it to expiration, or use it. Decide which before you need to.

What the premium really does
The premium works in two directions. It is the price of the floor, and it is also a drag on every profitable outcome. In the example, the stock has to rise $1.20 just to get back to even on the combined position. If you buy protection every month on the same shares, that drag adds up month after month.
The OIC is direct about this. It calls cost the major drawback of the strategy, because it raises the bar on netting upside profits. That is a damaging admission worth taking seriously. A protective put is a good tool when a specific risk is worth paying to remove. It is an expensive habit when it becomes routine.
What happens at expiration
At expiration, one of two things is true. If the stock is above the strike, the put expires worthless and you keep the shares. If the stock is below the strike, the put is in the money, and its value covers the drop below the strike. The holder can sell the put for that value, or exercise it and sell the shares at the strike.
How to choose the strike and expiration for a protective put
Choose the strike by deciding how much loss you can accept before the protection starts working, and choose the expiration by when the risk you are worried about will have passed. A strike close to the stock price protects sooner and costs more. A later expiration covers more time and also costs more.
Strike: how big a gap you can live with
The gap between the stock price and the strike is a deductible. With a $50 stock and a $48 put, you absorb the first $2 of any drop yourself. The put only pays for the part below $48. A $45 put leaves a $5 deductible. An at-the-money $50 put leaves almost none.
The infographic above shows the trade-off on the same 100 shares. Illustrative premiums: the $50 put costs $210 and caps the loss at $210. The $48 put costs $120 and caps it at $320. The $45 put costs only $45 but caps the loss at $545. Cheaper protection means a lower floor. There is no strike that gives you a high floor at a low price.
A practical way to choose: start from the dollar loss you are willing to take on the position, then find the strike where stock price minus strike plus premium comes closest to that number without going over it.
Expiration: the protection has to outlast the risk
A put protects only until it expires. If you are worried about an earnings report three weeks out, a put that expires in two weeks does nothing for the moment you care about. The usual approach is to choose an expiration safely after the event, accepting that a longer-dated put costs more.
Time works against the put buyer. The OIC notes that the passage of time has a negative impact on the strategy, because an option loses time value as expiration approaches. Every day the feared drop does not arrive, the put is worth a little less. That is the cost of carrying insurance.
Implied volatility sets the price
Option premiums rise when the market expects bigger moves. That means protection tends to be most expensive exactly when people want it most, such as before an earnings report or after a sharp drop. The SEC's bulletin lists volatility among the factors that determine an option's premium. The same strike on the same stock can cost far more in a nervous week than in a quiet one.
Protective puts vs stop orders and other ways to limit risk
A protective put guarantees an exit price at the strike until expiration, for a premium paid up front. A stop order costs nothing to place but does not guarantee its price, and it can be triggered by a brief dip. Which one fits depends on whether gaps, cost or upside matter most to the position.
The stop order problem a put solves
A stop order becomes a market order when the stop price is reached. The SEC's Investor Bulletin on stop, stop-limit and trailing stop orders points out that the stop price is not a guaranteed execution price, and that the price you actually receive can deviate significantly from it. If a stock closes at $50 and opens the next morning at $42 after bad news, a stop at $48 fills somewhere near $42, not $48.
A put does not have that problem. A 48-strike put gives you the right to sell at $48 regardless of where the stock opens, as long as the put has not expired. That certainty is what you pay the premium for. It is especially valuable around scheduled events where overnight gaps are common. Our guide to managing risk around news events covers the wider question of whether to hold through a catalyst at all.
How the main choices compare
| Approach | Up-front cost | Protects against a gap? | Upside kept | Main drawback |
|---|---|---|---|---|
| Shares with a stop order | None | No. The fill can be far below the stop | All of it, until stopped out | Can be triggered by a brief dip, then the stock recovers |
| Protective put | The premium | Yes, at the strike until expiration | All of it, minus the premium | Cost, plus time decay while nothing happens |
| Collar (protective put plus a short call) | Low, the call premium offsets the put | Yes, at the put strike | Only up to the call strike | Gives up gains above the call strike |
| Smaller position, no hedge | None | No, but the loss is smaller | All of it, on fewer shares | Less exposure to the move you expect |
| Long put alone (no shares) | The premium | Not a hedge. It is a bearish trade | Profits only if the stock falls | The whole premium is at risk |
Every way of limiting risk costs something. A protective put pays in premium, a stop order pays in gap risk, a collar pays in capped upside and a smaller position pays in exposure.
When a protective put makes sense, and when it does not
The OIC lists situations where investors consider protective puts: before a news announcement that could hit a favorite stock, when the value of a holding must be protected for a set period, when one stock is a large share of a portfolio, when the holder cannot sell for a time, or when a stockholder wants to protect a large unrealized gain. What these have in common is a specific risk over a specific window.
A protective put makes less sense as a permanent overlay on everything you own. Paying premium every month on every position is a reliable way to give back a large part of your returns. It also makes less sense when you are bearish on the stock for the long term. In that case, selling the shares is usually cheaper than insuring them.
- Name the specific risk you are protecting against and the date it arrives.
- Write down the maximum loss you will accept on the position, in dollars.
- Find the strike where stock price minus strike plus premium fits inside that number.
- Choose an expiration that falls safely after the event you are worried about.
- Calculate the breakeven: purchase price plus premium.
- Compare the premium with a stop order, a collar and a smaller position.
- Check implied volatility. Protection bought in a calm week usually costs less.
- Decide in advance whether you will sell the put back, hold it or use it.
Protective puts and a simulated funded options account
A classic protective put cannot be built in a TradeFundrr options account, because the accounts trade calls and puts, not shares. They are also intraday only, so nothing is held overnight. The protective logic still applies, though: in a defined-risk spread, the long option does the same job a protective put does for shares.
What the account pages say
TradeFundrr's options Pre-Prop and Prop pages list calls and puts on hundreds of liquid US underlyings, including index options such as SPX and ETF options on SPY, QQQ and IWM. Outright long calls and puts, spreads, iron condors and butterflies are supported, and credit-based positions are allowed up to account buying power. Trading is manual and intraday only, with no swing positions, Monday through Friday from 9:30 AM to 3:55 PM ET, and each trade must be held for at least 15 seconds.
Both accounts start with $25,000 in simulated buying power. Each carries a $1,000 daily loss limit that pauses trading for the rest of the session when it is reached, and a $3,000 maximum drawdown that trails the highest end-of-day balance and closes the account if it is reached. Contract limits per leg differ between Pre-Prop and Prop, and buying-power and risk limits apply, so confirm the current figures in your own account terms. Pre-Prop is a simulated evaluation account. Prop is a simulated funded account with no evaluation.
Exercise is a live-market event
In a live brokerage account, a protective put can end with exercise: the holder uses the put to sell their shares at the strike, and the trade settles through the clearing system. That does not happen in a simulated account. No real trade is executed, no shares are held, and positions are closed within the session. You will never exercise a put to deliver shares in a TradeFundrr account.
It is still worth knowing how exercise works, because it is a live-ready skill. If you ever run protective puts on shares you own in a personal brokerage account with your own money, you need to know the difference between selling an in-the-money put and exercising it, and what happens to your shares when you do. The simulated account is where you can practice the decisions that come before that point.
Where the protective idea lives on: the long leg
Look closely at a bull put spread and you will find a protective put inside it. A bull put spread sells a put and buys a lower-strike put. The bought put sets a floor under the sold one, exactly as a protective put sets a floor under shares. It turns an open-ended loss into a number you know before you enter.
That is why the logic matters in an account with a daily loss limit and a trailing drawdown. A position whose worst case is known in advance can be sized against those limits. If a spread's maximum loss is $300, you know how many of them fit inside a $1,000 daily loss limit before you place the first one. Our guide to debit spreads vs credit spreads covers how those structures are built and how the long leg defines the risk.
Frequently Asked Questions
What is a protective put?
A protective put is a put option bought to protect shares you already own. It gives you the right to sell the shares at the strike price until expiration, so it caps the position's loss while keeping the upside, minus the premium paid.
How do you calculate the maximum loss on a protective put?
Subtract the strike price from the stock purchase price and add the premium paid, then multiply by 100 for each contract. Shares bought at $50 with a 48-strike put bought for $1.20 have a maximum loss of $3.20 per share, or $320.
What is the breakeven on a protective put?
The breakeven at expiration is the stock purchase price plus the premium paid for the put. For shares bought at $50 with a $1.20 put, the stock must be above $51.20 at expiration for the combined position to show a profit.
Is a protective put better than a stop-loss order?
Neither is better in every case. A put guarantees the strike as an exit price until expiration, including through overnight gaps, but costs a premium. A stop order costs nothing to place, but its fill price is not guaranteed and a brief dip can trigger it.
What is the difference between a protective put and a married put?
Only the timing. A protective put is bought to hedge shares you already own. A married put is bought at the same time as the shares. The payoff at expiration is the same.
Can I buy protective puts in a TradeFundrr options account?
Not in the classic form. TradeFundrr options accounts trade calls and puts, not shares, so there are no shares to protect. Long puts and spreads are supported, and the long leg of a spread does the same floor-setting job.
Can my put be exercised in a funded account?
No. Exercise is a live-market event that settles through the clearing system. TradeFundrr accounts are simulated, no real trade is executed, and positions are closed within the session, so puts are never exercised to sell shares.
How do I limit risk on an options trade in a funded account?
Use structures with a known maximum loss, such as long options or spreads, and size them against the account's $1,000 daily loss limit and $3,000 trailing drawdown. Contract limits also apply, so confirm the current figures in your account terms.
A protective put is one of the clearest trades in options. You pay a known price for a known floor, and you can calculate both before you buy. That clarity is the point. The trader who knows their maximum loss in dollars before entering is making a different kind of decision from the trader who is hoping the stock holds up.
In a simulated, intraday options account you will not hold shares to protect, but you will hold positions whose worst case you need to know. Build that habit on every trade. Name the risk, set the floor, count the cost and decide whether it is worth paying.
Know your floor before you trade
TradeFundrr's simulated options accounts support long calls and puts, spreads, iron condors and butterflies, with a daily loss limit and a trailing drawdown written down before your first trade.
