Explained Simply
A collar wraps a stock position in two options: you buy an out-of-the-money put below the current price (the floor) and sell an out-of-the-money call above it (the ceiling). The premium received from selling the call offsets part or all of the put cost, often creating a zero-cost or near-zero-cost hedge. Example: you own 100 shares of AAPL at $190. You buy a $180 put for $3.00 and sell a $200 call for $3.00. Your downside is limited to $180 (a $10 loss) and your upside is capped at $200 (a $10 gain), but the hedge costs nothing. Collars are used by investors who want to protect unrealized gains without selling the stock, especially heading into earnings, macro uncertainty, or tax-sensitive periods.
How a Collar Works Step by Step
A collar requires three components held simultaneously:
1. Long stock: You must own at least 100 shares of the underlying stock (per contract).
2. Long put (protective put): Buy an out-of-the-money put at a strike price below the current stock price. This establishes the floor — your maximum loss is the difference between the stock price and the put strike, minus any net credit received.
3. Short call (covered call): Sell an out-of-the-money call at a strike price above the current stock price. This caps your upside but generates premium that offsets the put cost.
Example: You own 100 shares of MSFT at $420. You buy a 30-day $400 put for $5.50 and sell a 30-day $440 call for $5.50. Net cost: $0 (zero-cost collar). Your outcomes: if MSFT drops to $350, your shares lose $70 but the put is worth $50, so your net loss is $20 (capped at $400 floor). If MSFT rises to $460, your shares gain $40 but the call caps you at $440, so your net gain is $20. If MSFT stays between $400 and $440, both options expire worthless and you keep the shares.
When to Use a Collar
Protecting concentrated stock positions: Employees with large company stock holdings use collars to lock in gains without triggering a taxable sale event.
Earnings hedging: If you want to hold through earnings but limit downside, a collar provides protection without exiting the position.
Market uncertainty: When macro events (Fed decisions, geopolitical risk) create elevated short-term risk, collars protect against a sharp drop while keeping the position open.
Tax planning: Collars allow investors to defer capital gains to the next tax year while maintaining downside protection today.
When NOT to use: Collars limit upside, so avoid them when you have strong conviction the stock will rally significantly. If the stock regularly moves more than the collar width (distance between put and call strikes), you are giving up too much upside relative to the protection gained.
Collar vs Protective Put vs Covered Call
A collar combines a covered call and a protective put into a single strategy. Understanding each component clarifies when the collar is the right choice:
Protective put only: Buying a put protects downside but costs premium. No upside cap. Best when you are very bullish but want insurance against a tail event.
Covered call only: Selling a call generates income but provides no downside protection. Best when you expect modest upside and want to enhance yield.
Collar (both): The put premium is funded by the call premium. You accept capped upside in exchange for reduced or zero-cost downside protection. Best when you are neutral to moderately bullish but want to sleep at night.
Cost comparison: A 30-day protective put on a $100 stock might cost $2.50. A collar using that same put plus a covered call might net $0.25 or even generate a small credit. The collar is far more capital-efficient for hedging.
How to Use Collar (Options)
- 1
Own the Underlying Shares
A collar protects an existing stock position. You need to already own 100 shares. Collars are typically used on positions with large unrealized gains that you want to protect without selling (for tax reasons or because you want to maintain the position).
- 2
Buy a Protective Put
Buy an OTM put with a strike 5-10% below the current price. This sets your downside floor — the most you can lose is the difference between the current price and the put strike. For a stock at $100, a $90 put limits your loss to $10 per share.
- 3
Sell a Covered Call to Finance the Put
Sell an OTM call with a strike 5-10% above the current price. The premium received offsets (partially or fully) the cost of the protective put. For a stock at $100: buy $90 put for $3, sell $110 call for $3 = zero-cost collar.
- 4
Understand the Tradeoff
You've capped both your downside (at the put strike) and your upside (at the call strike). In our example: max loss = $10/share, max gain = $10/share. The collar gives peace of mind during uncertain periods in exchange for limited upside.

Choose When to Use a Collar
Use collars before earnings, ahead of market uncertainty, or to lock in gains without selling. Remove the collar when conditions improve by buying back the call and selling the put. Don't collar permanently — the capped upside reduces long-term returns.
Frequently Asked Questions
What is a collar strategy in options trading?
A collar strategy involves owning stock, buying a protective put below the current price, and selling a covered call above it. The call premium offsets the put cost, often creating a zero-cost or near-zero-cost hedge. The result is a defined range: your losses are floored at the put strike and your gains are capped at the call strike.
Is a collar a good strategy for beginners?
Yes, collars are one of the most conservative options strategies available. They require no margin beyond owning the stock, have clearly defined risk parameters, and are easy to understand. The main limitation is capped upside, which makes them less suitable when you expect a large rally. For investors who want to protect gains on a stock position without selling, a collar is an excellent starting strategy.
Can you lose money on a collar?
Yes, but losses are limited. Your maximum loss is the difference between the stock price and the put strike price, minus any net credit received from the options. For a zero-cost collar on a $100 stock with a $90 put and $110 call, the worst-case loss is $10 per share regardless of how far the stock drops.
How Tradewink Uses Collar (Options)
When the risk management engine detects elevated downside risk on a position with large unrealized gains, it evaluates collar structures. The system selects put strikes near key support levels and call strikes above near-term resistance to maximize the protective range while minimizing net cost.
