The Options Collar: A Cheap Hedge

The collar bounds a stock position between a floor and a ceiling for close to nothing. You already own the shares. You buy a protective put below the current price to set the floor, and you sell a covered call above it to set the cap. The premium the call brings in pays for the put. The stock can no longer fall past the floor or rise past the cap, and the whole hedge often costs near zero.

This is the position a founder or long-tenured employee reaches for when a single stock has grown into most of their net worth and selling would hand a large slice to the tax collector. The shares stay put. The dividends keep arriving. The downside gets a hard floor, paid for by renting out the upside above the cap.

What a collar is made of

A collar has three pieces held together at once:

1. The stock, already owned, 100 shares for every one option contract.
2. A long put struck below today's price. This is the floor. It gives you the right to sell at that strike no matter how far the stock drops. A put on its own is covered in what put options are.
3. A short call struck above today's price. This is the cap. A buyer pays you for the right to take your shares at that strike, and in return any gain above it belongs to them. Selling a call you can back with stock is a covered call.

The put costs money. The call brings money in. Pick the two strikes so the call premium roughly covers the put, and the insurance is nearly free. Sometimes the call brings in more than the put costs, and you are paid to hedge.

A real collar: SPY, June 2026

On June 4, 2026, SPY closed at $754.56. A collar built around that price used the June 18 contracts:

• Buy the $740 put for $2.75. That is the floor.
• Sell the $760 call for $5.65. That is the cap.

The call brought in $5.65 and the put cost $2.75, a net credit of about $2.90 for the pair. The hedge was free, and then some. From that moment the position could not settle below $740 or above $760 at the June 18 expiry, whatever SPY did in between.

Here are the two legs traced side by side through the following two weeks:

SELECT p.date AS date,
       round(avg(p.option_close), 2) AS put_740,
       round(avg(c.option_close), 2) AS call_760
FROM global_markets.options_greeks p
INNER JOIN global_markets.options_greeks c ON p.date = c.date
WHERE p.ticker = 'O:SPY260618P00740000' AND c.ticker = 'O:SPY260618C00760000'
  AND p.date BETWEEN '2026-06-04' AND '2026-06-15'
  AND p.implied_volatility > 0.02 AND c.implied_volatility > 0.02
GROUP BY p.date ORDER BY p.date

The lines pull apart the instant the stock moves. Watch them against SPY itself, with the floor and cap drawn in:

SELECT date,
       round(avg(underlying_close), 2) AS spy,
       740 AS floor,
       760 AS cap
FROM global_markets.options_greeks
WHERE ticker = 'O:SPY260618P00740000' AND date BETWEEN '2026-06-04' AND '2026-06-15' AND implied_volatility > 0.02
GROUP BY date ORDER BY date

SPY dropped from $754.56 on June 4 to $722.88 on June 10, more than $30 a share in four sessions. Unhedged, 100 shares lost over $3,000 of paper value. Inside the collar the story was different. The $740 put climbed from $2.75 to $18.7 as the stock fell toward and then through its strike. Every dollar the put gained offset a dollar the stock lost below $740. The $760 call, meanwhile, faded from $5.65 to $0.28, nearly worthless. As the call writer, you keep that premium.

How the floor takes over

A put does not protect all at once. Its grip tightens as the stock falls toward the strike, and the greek that measures that grip is delta. Here is the $740 put's delta across the same two weeks:

SELECT date,
       round(avg(delta), 3) AS put_delta
FROM global_markets.options_greeks
WHERE ticker = 'O:SPY260618P00740000' AND date BETWEEN '2026-06-04' AND '2026-06-15' AND implied_volatility > 0.02
GROUP BY date ORDER BY date

On June 4, with SPY well above the strike, the put's delta was $-0.223: it moved only lightly against the stock. By June 10, with SPY at $722.88, the delta reached $-0.796, close to moving one-for-one opposite the shares. The floor was fully engaged, the put now offsetting almost the entire drop dollar for dollar. As SPY recovered into $753.91 by June 15, the delta faded back toward zero and the floor loosened its grip. How each greek shifts over a contract's life is the subject of how the greeks change over time.

What the collar bounded

Add the pieces up from the June 4 setup. The worst case at the floor: the stock can fall to $740 and no further in effect, a loss of about $14.56 a share from the $754.56 entry, softened by the $2.90 credit to roughly $11.66. The best case at the cap: the stock can rise to $760, a gain of about $5.44 a share, plus the credit. Between $740 and $760 the position simply tracks the stock. A wide, cheap box around a holding you did not want to sell.

The trade-off is the ceiling. When SPY recovered to $753.91 the collar holder participated up to $760 and no further; a big rally above the cap would have been rented away. A collar buys a floor with the upside above the cap. For a concentrated holder who mainly wants to avoid getting hurt, that is often a trade worth making. When to unwind it turns on the calendar, covered in when options expire.

FAQ

What is an options collar in simple terms?

A collar is a three-part position: you own a stock, you buy a put below its price to cap your losses, and you sell a call above its price to pay for that put. It boxes the stock between a floor and a ceiling until the options expire.

Does a collar cost money?

Usually very little, and sometimes nothing. The call you sell brings in premium that offsets the put you buy. In the SPY example above the call actually brought in more than the put cost, a net credit of about $2.90 per share.

What is the downside of a collar?

The cap. In exchange for the floor, you give up any gain above the call's strike. If the stock rallies hard past the ceiling, those gains belong to the call buyer, not you. A collar suits an investor who values protection over another leg of upside.

Why do business owners use collars?

A collar hedges a concentrated stock position without selling it, which avoids a taxable sale and keeps the dividends and voting rights intact. It is a common tool for founders and executives sitting on a single large holding.

How is a collar different from just buying a put?

A lone put is pure insurance you pay for out of pocket, covered in buying and selling puts. A collar funds that insurance by selling a call, which trades away your upside above the call strike in return. One costs money and keeps all the upside; the other is nearly free and caps it.
