Collar Strategy: Protect Your Stock Without Selling

You own 500 shares of a stock that has run up 40% this year. You do not want to sell — maybe there are tax reasons, maybe you believe in the long-term thesis, maybe you are restricted from selling.

But you also cannot stomach watching those gains evaporate in a pullback.

The collar strategy lets you protect your position without selling a single share. And in many cases, it costs you nothing.

What Is a Collar?

A collar combines two options around a stock you already own:

1. Buy a protective put below the current price (sets your floor)
2. Sell a covered call above the current price (caps your upside, pays for the put)

You are wrapping a collar around your stock position — protection on the downside, a ceiling on the upside. The covered call premium offsets part or all of the put cost.

Here is a concrete example. You own 100 shares of XYZ at $100:

• Buy the $95 put for $2.50 (protection below $95)
• Sell the $110 call for $2.50 (cap above $110)
• Net cost: $0.00

This is a zero-cost collar. The call premium exactly pays for the put. Your stock can move freely between $95 and $110. Below $95, the put protects you. Above $110, your shares get called away at $110.

Zero-Cost vs Net-Debit Collar

Not every collar is free. The relationship between the put cost and the call premium depends on how far out-of-the-money you place each strike.

Zero-Cost Collar

The call premium equals the put cost. You give up more upside to pay for more protection. In the example above, capping gains at $110 (10% above current price) paid for protection at $95 (5% below).

This is the most common setup for investors who primarily want protection and are comfortable limiting upside.

Net-Debit Collar

The put costs more than the call generates. This happens when you want tighter protection (put strike closer to current price) or want to keep more upside (call strike further out).

Example:

• Buy the $97 put for $3.50
• Sell the $115 call for $1.50
• Net cost: $2.00

You pay $200 per contract for the collar, but your protection starts at $97 (only 3% below) and your upside extends to $115 (15% above). This might be worth it if you expect the stock to keep climbing but want a tighter safety net.

Net-Credit Collar

Occasionally, you can set up a collar that actually pays you. This requires selling a call closer to the money than the put you buy:

• Buy the $90 put for $1.50
• Sell the $105 call for $2.50
• Net credit: $1.00

You collect $100 per contract but accept a wider gap before protection kicks in (stock must drop 10% before the put helps) and a lower ceiling (gains capped at 5%).

Step-by-Step Setup

Step 1: Determine Your Protection Level

How much drawdown can you tolerate? This sets your put strike.

• Tight protection (3-5% OTM put): More expensive, but you limit losses to a small percentage. Best for concentrated positions or nervous markets.
• Moderate protection (5-10% OTM put): The standard range. Gives the stock room to breathe while preventing significant damage.
• Wide protection (10-15% OTM put): Cheap, but only protects against a major crash. More of a catastrophe hedge than everyday protection.

Step 2: Select Your Call Strike

How much upside are you willing to give up? This sets your call strike and determines how much of the put cost you offset.

• Aggressive call (5-10% OTM): Generates more premium, pays for a tighter put, but caps your gains sooner.
• Conservative call (15-20% OTM): Less premium, so the collar costs more (net debit), but you keep significant upside potential.

Step 3: Match Expirations

Both the put and call should have the same expiration date. Standard collar durations:

• 30-60 days: For short-term protection around a specific event (earnings, FDA decision, macro uncertainty).
• 90-180 days: For broader portfolio protection. Fewer rolls, lower transaction costs per month.
• LEAPS (6-12 months): For long-term holders who want set-it-and-forget-it protection. Higher premiums but less management.

Step 4: Check the Net Cost

Add up the put cost and call credit. If the result is near zero, you have a zero-cost collar. If you are paying a debit, decide whether the protection is worth the cost.

Compare the collar cost against simply buying a protective put without the call. The call premium typically reduces your hedging cost by 40-70%.

When to Use a Collar

Collars shine in specific situations:

Before Earnings on a Winning Position

You hold a stock that reports next week. You are up 30% and do not want to sell before the announcement. A collar lets you participate in further upside (up to the call strike) while putting a floor under your gains.

Concentrated Stock Positions

Employees and founders often hold large positions in a single stock. A collar provides protection without triggering a taxable sale. But read the tax section below carefully.

Lockup Expiry

Pre-IPO shareholders facing a lockup expiry know a flood of selling may hit the stock. A collar protects against that wave while keeping the position intact.

General Market Uncertainty

If you hold a portfolio of individual stocks and implied volatility is spiking across the market, collars on your largest positions can reduce portfolio risk at a reasonable cost. When IV is high, the call premium you collect is richer, making zero-cost collars easier to achieve.

Tax Considerations: The Constructive Sale Trap

This is critical. If your collar is too tight — meaning the put and call strikes are very close to the current stock price — the IRS may treat it as a constructive sale. This means you could owe capital gains taxes as if you sold the stock, even though you still own it.

There is no bright-line rule for what "too tight" means, but the general guidance:

• A zero-cost collar with the put and call both within 5% of the current price is risky from a tax perspective.
• Wider collars (put 10% below, call 10-15% above) are generally safe.
• LEAPS collars have more scrutiny than short-term collars.
• Consult a tax advisor before collaring a position with large unrealized gains. This is not optional — it is the most common collar mistake.

Real Example: Protecting a Winner

You bought 200 shares of ABC at $75. The stock is now at $120 — a 60% gain. Earnings are in three weeks and you are nervous.

Setup (45 DTE):

• Stock: ABC at $120
• Buy 2x $112 puts at $3.00 each = $600 total cost
• Sell 2x $130 calls at $3.00 each = $600 total credit
• Net cost: $0

Outcomes at expiration:

• ABC drops to $100: Your puts are worth $12 each. Your stock loss is $20 per share, but the puts recover $12. Net loss from current price: $8 per share instead of $20. The collar saved you $2,400.
• ABC stays at $120: Both options expire worthless. Zero cost, zero benefit. You still own your shares.
• ABC rallies to $140: Your shares get called away at $130. You capture $10 of upside per share ($2,000 total) but miss the last $10 of the move. The collar cost you $2,000 in upside you would have otherwise captured.
• ABC rallies to $125: You keep all the gains. The call expires worthless, the put expires worthless. This is the sweet spot.

Collar vs Protective Put Alone

Why not just buy the put and skip the call?

Factor	Collar	Protective Put Only
Cost	Zero or near-zero	Full put premium
Downside Protection	Same	Same
Upside Potential	Capped at call strike	Unlimited
Best For	Protection-focused investors	Investors expecting large rally
IV Impact	Partially neutralized	Fully exposed to IV changes

The collar wins when your primary goal is protection and you are willing to trade upside for lower cost. The protective put alone wins when you think the stock could make a big move higher but you want catastrophe insurance.

For most investors protecting winning positions, the collar is the better choice. Giving up some upside to hedge for free is a trade most professionals happily make.

Management and Rolling

If the Stock Approaches Your Call Strike

Your shares may get called away. If you want to keep them:

• Buy back the call (at a loss) before expiration
• Roll the call to a higher strike and/or later expiration for a credit or small debit

If the Stock Drops Toward Your Put Strike

Your protection is working. At expiration, you can:

• Exercise the put to sell shares at the strike price
• Sell the put for its intrinsic value and keep the shares
• Roll the put to a lower strike and later expiration if you want continued protection

At Expiration

If both options expire worthless (stock between the strikes), the collar cost you nothing and you still own your shares. You can put on a new collar for the next period.
