Options Collar: How to Put a Floor and a Ceiling Around a Stock Position in 2026
October 26, 2026
14 min read
An options collar is a three-part position: you own 100 shares of a stock, you buy a put below the current price, and you sell a call above it. The put sets a floor under the shares. The call sets a ceiling on them, and the premium you collect for selling it pays for some or all of the put. Between the two strikes, the shares move as they normally would. Outside them, the result is locked.
Traders like the options collar because it turns open-ended risk into a known range for a known cost, often close to zero. The catch is that the cost does not disappear. It moves. Instead of paying a large premium for protection, you pay by giving away any gain above the call strike, and if the stock rallies hard, that can be the most expensive thing you ever gave away.
In this guide we'll cover what an options collar is and how its three parts work together, how to calculate the floor, the ceiling and the breakeven, how to choose strikes and an expiration, how the collar compares with a protective put, a covered call and a stop order, and what all of this means in a simulated funded options account, where you trade calls and puts but do not hold shares.
Key Takeaways
- Calculate both edges before you trade. The floor is the stock price minus the put strike, adjusted for the net premium. The ceiling is the call strike minus the stock price, adjusted the same way. Write both numbers down first.
- Treat the short call as the price of the floor. A collar that costs nothing up front still has a cost: every dollar the stock rises above the call strike belongs to someone else.
- Choose the strikes by the range you can live with. A tighter collar protects sooner and caps gains sooner. A wider one leaves more room in both directions.
- Know the live-account risks. In a brokerage account, the short call can be assigned, which means your shares are sold at the call strike, sometimes early and often just before an ex-dividend date.
- Carry the logic, not the structure, into a funded account. TradeFundrr options accounts trade calls and puts, not shares, so the collar's trade-off lives on in vertical spreads, where a short option pays for a long one.

What is an options collar?
An options collar is a hedge for a stock you already own: one long put below the current price and one short call above it, usually with the same expiration, for every 100 shares. The put gives you a minimum sale price. The call obligates you to sell at a maximum price if the buyer exercises. The shares are "collared" between the two strikes.
The three parts of the position
The first part is the stock. You own it, and you want to keep owning it, but you are worried about a decline over a specific period. The second part is a long put. It gives you the right, but not the obligation, to sell the shares at the put strike until expiration. That is the same piece our guide to protective puts covers in detail.
The third part is a short call. When you sell a call, you collect a premium and take on an obligation. The SEC's Investor Bulletin on an introduction to options explains it directly: the seller of a call option is obligated to sell the shares to the buyer who exercises the option on or before expiration. In a collar, the shares you already own cover that obligation, which is the same structure as a covered call.
Why it is called a collar
The Options Industry Council, the education arm of the Options Clearing Corporation, describes the collar, or protective collar, as a combination of two hedging strategies: protective puts and covered call writing. The OIC refers to the two strikes as the floor and the ceiling of the position. The put strike establishes a minimum exit price. The call strike sets an upper limit on gains.
The OIC also describes who the strategy is for: a stockholder who is neutral to moderately bullish, looking for a slight rise, but worried about a decline. It calls the collar a temporary, slightly less-than-complete hedge. Temporary, because the options expire and the protection ends with them. Less than complete, because you still absorb the drop from today's price down to the put strike.
How to calculate a collar's floor, ceiling and breakeven
Three numbers describe any collar. The maximum loss is the stock purchase price minus the put strike, plus any net premium paid or minus any net credit received. The maximum gain is the call strike minus the stock purchase price, minus a net debit or plus a net credit. The breakeven is the stock purchase price plus a net debit, or minus a net credit.
A worked example
Illustrative example: a trader owns 100 shares bought at $100. They buy one 95-strike put for $2.10 and sell one 105-strike call for $1.90, both expiring in about six weeks. The put costs $210. The call brings in $190. The net cost of the collar is $0.20 per share, or $20 for the position.
Maximum loss: ($100 minus $95) plus $0.20 equals $5.20 per share, or $520. It does not matter how far the stock falls below $95. The put covers everything under the strike.
Maximum gain: ($105 minus $100) minus $0.20 equals $4.80 per share, or $480. It does not matter how far the stock rises above $105. Everything above the call strike is given up.
Breakeven at expiration: $100 plus $0.20 equals $100.20.
Now compare the collared position with the shares alone. At $85, the bare shares are down $1,500 and the collared position is down $520. At $110, the bare shares are up $1,000 and the collared position is up $480. That trade, roughly $980 of protection on the downside for $520 of give-up on the upside in this example, is the whole decision.

The collar as a price band
100 shares bought at $100, plus a long 95 put and a short 105 call with the same expiration. Inside the band the shares move normally. Outside it, the result is fixed.
Who pays for the floor
At expiration, three prices
Three shapes of the same collar
- 1Name the risk window. Both options must outlast it.
- 2Set the floor. Pick the loss you accept first.
- 3Price the ceiling. See what the call pays at each strike.
- 4Plan for assignment. Know what happens if the call is exercised.
tradefundrr.comIllustrative example. Option premiums are hypothetical and chosen to show the arithmetic, not quoted from any market. Results are at expiration for 100 shares and ignore commissions.
What happens at expiration
At expiration, the stock is in one of three places. Below the put strike, the put is in the money and its value offsets the drop below $95; the call expires worthless. Between the strikes, both options expire worthless and you keep the shares at whatever they are worth. Above the call strike, the call is in the money, and in a live brokerage account you will most likely be assigned and sell the shares at $105.
That last case surprises people. A collar can end your ownership of the shares. To keep the stock no matter what, you need a plan to buy the call back before expiration, which costs more the further the stock has run.
Why time and volatility matter less here
The OIC notes that time decay and changes in implied volatility are usually not major factors for a collar, because you are long one option and short another with the same expiration, often at a similar distance from the stock price. What the long put loses to time, the short call tends to give back, an advantage over a protective put on its own.
How to choose collar strikes and expiration
Choose the put strike by the loss you can accept, the call strike by the gain you are willing to give up, and the expiration by when the risk you are worried about will have passed. The distance between the two strikes sets the width of the band. The prices of the two options set whether the collar costs you money, costs nothing or pays you.
The put strike: how low is too low
The gap between the stock price and the put strike works like a deductible. With shares at $100 and a $95 put, you absorb the first $5 of any drop yourself. A $97 put leaves a smaller deductible but costs more. A $90 put is cheaper but leaves a $10 hole before protection starts.
Start from a dollar number and work backward from the loss, not forward from the price that looks cheapest.
The call strike: what you are willing to give away
The call strike is the other half of the deal. A call closer to the stock price brings in more premium, which pays for more of the put, and it caps your gains sooner. A call further away pays less and leaves more room to run.
In the infographic above, all three collars use the same $95 put. Moving the call from $105 to $104 makes the collar free up front and lowers the ceiling from $480 to $400. Moving it to $102 turns the collar into a credit and lowers the ceiling to $290. There is no strike that gives you a high floor, a high ceiling and a low cost at once.
Zero-cost collars and what "free" means
A zero-cost collar uses a call whose premium roughly matches the put's, so no money changes hands at the start. It feels like free insurance. It is not. You pay in a different currency: any gain above the call strike, which in a sharp rally can cost more than any premium would have.
Expiration: outlast the risk
Both options protect only until they expire. If the risk is an earnings report in four weeks, a collar that expires in three weeks protects you through nothing that matters. Choose an expiration after the event. The OIC notes that collars lend themselves to longer-dated options, where premiums are higher and the period of protection is longer.
Collars vs protective puts, covered calls and stop orders
A collar costs less up front than a protective put and protects more than a covered call, because it combines the two. A stop order costs nothing to place but does not guarantee its price. Which one fits depends on whether you care most about cost, gap protection or keeping your upside.
Collar vs protective put
A protective put keeps all of your upside and charges you a premium for the floor. A collar keeps the floor and replaces most or all of that premium with a cap. If you expect the stock to stay roughly where it is, the collar is cheaper. If you expect a big move up after the risk passes, the protective put leaves that move to you.
Collar vs covered call
A covered call pays you a premium and caps your upside, but it does nothing about a large drop beyond the premium you collected. Our guide to covered calls and cash-secured puts walks through that trade-off. Adding the put turns a yield trade into a hedge. You give up some of the call income to buy a floor.
Collar vs stop order
A stop order becomes a market order once the stop price is reached. The SEC's Investor Bulletin on stop, stop-limit and trailing stop orders warns that the price you actually receive can deviate significantly from the stop price. If a stock closes at $100 and opens at $88 after bad news, a stop at $95 fills near $88. A $95 put still lets you sell at $95.
| Approach | Up-front cost | Protects against a gap? | Upside kept | Main drawback |
|---|---|---|---|---|
| Collar | Small, zero or a credit | Yes, at the put strike until expiration | Only up to the call strike | Gains above the call strike are given up, and the shares can be called away |
| Protective put | The full put premium | Yes, at the put strike until expiration | All of it, minus the premium | Cost, plus time decay while nothing happens |
| Covered call | None, you collect a premium | No. Only the premium cushions a drop | Only up to the call strike | Full downside below the premium received |
| Stop order on the shares | 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 |
| Smaller position, no hedge | None | No, but the loss is smaller | All of it, on fewer shares | Less exposure to the move you expect |
How common ways of limiting risk on a stock position compare. Every one of them costs something: premium, upside, gap risk or exposure.
When a collar makes sense, and when it does not
A collar fits a specific situation: you want to keep the shares, you are worried about a decline over a known window, and you can live with a capped gain during that window. A large unrealized gain you do not want to give back, or a single stock that has grown into too much of your account, are classic cases.
It fits less well when you are strongly bullish, because the call takes the move you are hoping for, or strongly bearish, because selling the shares is simpler. Rolled month after month on everything you own, a collar stops being a hedge and becomes a cap on your returns.
- Name the specific risk you are hedging and the date it passes.
- Write down the largest loss you will accept on the shares, in dollars.
- Pick the put strike that keeps the loss, including net premium, inside that number.
- Write down the gain you are willing to give up, and pick the call strike from it.
- Calculate the maximum loss, maximum gain and breakeven before you place the order.
- Choose an expiration safely after the event, and use the same expiration for both legs.
- Check the ex-dividend date. Early assignment risk on the short call rises just before it.
- Decide in advance what you will do if the stock runs through the call strike.
Options collars and a simulated funded options account
A classic collar 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 and a six-week hedge has no place to live. The collar's core idea does carry over, though: selling one option to pay for another, and accepting a cap in return.
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. A position limit applies per leg, and it differs by account, so confirm the current figure in your own account terms.
The collar's logic inside a vertical spread
Look at what a collar really does: it buys one option and sells another at a different strike so the sale pays for the purchase, and it accepts a capped result in exchange. A vertical spread does exactly that with no shares involved. In a call debit spread, you buy a call and sell a higher-strike call; the short call lowers your cost and caps your gain at the higher strike. In a put debit spread, the same trade-off applies on the downside.
The maximum loss on a debit spread is the net premium you paid, which you know before you enter. Our guide to vertical spreads for defined risk covers how to size one, and the same questions from the collar checklist apply: what loss you accept, what gain you give up, and what the trade-off costs.
Why a collar without shares is a different trade
It can be tempting to build "a collar" in an options-only account by buying a put and selling a call with no stock underneath. That is not a hedge. Without the shares, the short call is uncovered, and its risk grows as the underlying rises. The position behaves like a bearish bet, not like protection. If you are unsure how the platform treats an uncovered short option, ask support before you place one, and keep your risk defined.
Assignment is a live-account event
In a live brokerage account, the short call in a collar can be assigned, which means the call buyer exercises and your shares are sold at the call strike. The OIC notes that early assignment of the short call is possible at any time but generally happens just before the stock goes ex-dividend. In a simulated account, no real trade is executed, so no counterparty can exercise against you. And because TradeFundrr options accounts are intraday only, your plan should have every position closed before the 3:55 PM ET cutoff, so expiration and assignment are not part of the day. If you ever leave something open by mistake, ask support how the platform handles it rather than guessing.
Learning assignment anyway is a live-ready skill. Traders who later run collars on shares in a brokerage account of their own will face it, and knowing why a call gets exercised early prevents an expensive surprise.
Frequently Asked Questions
What is an options collar?
An options collar is a hedge on a stock you own: you buy a put below the current price and sell a call above it, usually with the same expiration. The put sets a minimum sale price, and the call premium pays for some or all of the put in exchange for capping your gains.
Is a zero-cost collar really free?
No. A zero-cost collar costs nothing up front because the call premium matches the put premium, but you pay by giving up every dollar of gain above the call strike. If the stock rallies hard while the collar is in place, that give-up can exceed any premium you would have paid.
What is the maximum loss on a collar?
The maximum loss is the stock purchase price minus the put strike, plus any net premium paid or minus any net credit received. In the illustrative example in this guide, shares bought at $100 with a $95 put and a $0.20 net debit can lose at most $5.20 per share, or $520.
What happens if the stock goes above the call strike?
Your gain is capped at the call strike. In a live brokerage account, the call will probably be exercised at expiration and your shares sold at that strike. To keep the shares, you would need to buy the call back before then, which costs more the further the stock has risen.
Can I trade a collar in a TradeFundrr funded account?
Not in its classic form. TradeFundrr options accounts trade calls and puts, not shares, and are intraday only, so there are no shares to collar. The same trade-off, selling one option to pay for another and accepting a cap, is available through defined-risk vertical spreads.
Can my short call be assigned in a TradeFundrr options account?
Assignment is a live-market event. In a simulated account, no real trade is executed, so no counterparty can exercise against you. The accounts are also intraday only, so positions should be closed before the 3:55 PM ET cutoff. Ask support how the platform handles anything left open.
What is the difference between a collar and a vertical spread?
A collar combines two options with shares you own, so the long put protects the stock and the short call caps it. A vertical spread uses two options of the same type on the same underlying with no shares. Both use a short option to pay for a long one and accept a capped result.
A collar shows the cost of protection plainly. You get a floor. You pay for it with a ceiling. The only mistake is pretending that exchange is not there.
Whether you collar shares in a brokerage account of your own or trade spreads in a simulated funded account, the habit is the same: decide the loss you accept, decide the gain you give up, and write both down before you click.
Practice defined-risk options with the limits known up front
TradeFundrr's simulated options accounts publish the buying power, daily loss limit and trailing drawdown before you start, so every spread you build is sized against rules you already know.
