Collar

What Is a Collar?

A collar involves owning 100 shares of stock, buying a protective put below the current price, and selling a call above the current price. The call premium pays for (or partially pays for) the put, creating low-cost or "costless" downside protection while capping your upside. This is portfolio insurance for stock you want to hold long-term.

Quick Stats:

• Max Loss: Limited to put strike (minus net cost/credit)
• Max Profit: Limited to call strike (plus net cost/credit)
• Breakeven: Stock purchase price ± net cost or credit
• Best For: Protecting unrealized gains, hedging long positions, defensive strategy

When to Use a Collar

✅ Ideal Conditions

• Own stock with large unrealized gains you want to protect
• Uncertain market conditions ahead (recession fears, volatility)
• Want to hold stock long-term but reduce short-term risk
• Earnings or major catalyst approaching
• Need to lock in gains without selling (tax reasons)
• Stock overextended, expecting pullback
• Portfolio hedging during market uncertainty

❌ Avoid When

• Expecting strong continued upside (collar caps gains)
• Don't own the underlying stock (not a collar, different strategy)
• Stock in strong uptrend with no concerns
• Want unlimited upside potential
• Cost of put exceeds call premium significantly (expensive collar)
• Holding period is very short-term (just sell the stock instead)

How Collars Work

The Three Components

A collar consists of three positions:

Long Stock:

• Own 100 shares
• Full upside and downside exposure without collar

Long Protective Put (Insurance):

• Buy OTM put below current price
• Protects against downside below strike
• Costs premium (insurance payment)

Short Covered Call (Premium Collection):

• Sell OTM call above current price
• Caps upside at strike
• Collect premium (pays for insurance)

The call premium offsets the put cost, creating low-cost or zero-cost protection.

Collar Structure

ComponentExampleAmountOwn 100 shares@ $100/share$10,000 investedBuy $95 put-$2.00-$200Sell $110 call+$2.00+$200Net Cost/Credit$0 (costless)Protected Range$95-$110

Downside protection: Can't lose below $95

Upside cap: Can't profit above $110

How to Set Up a Collar

Step 1: Own 100 Shares (Required)

Requirements:

• Must own 100 shares per collar
• Can collar 200 shares with 2 collars, etc.
• Shares act as the underlying position

Example:

• Own 500 AAPL shares bought at $120
• Now at $180, sitting on $30k unrealized gain
• Want to protect gains through earnings

Step 2: Select Put Strike (Downside Protection)

Placement options:

Put SelectionProtection LevelCostBest For5% OTMTight protectionExpensiveMaximum safety10% OTMModerate protectionModerateBalanced15% OTMLoose protectionCheapLight hedging

Example: Stock at $180

• Conservative: Buy $175 put (2.8% OTM, maximum protection)
• Moderate: Buy $170 put (5.6% OTM, balanced)
• Aggressive: Buy $165 put (8.3% OTM, cheap insurance)

Key decision: How much downside can you tolerate?

• Willing to lose 5%? Use $171 put
• Willing to lose 10%? Use $162 put

Step 3: Select Call Strike (Upside Cap)

Placement options:

Call SelectionUpside RoomPremiumBest For5-7% OTMSmall roomHigh premiumCost offset, lower expectations10-15% OTMModerate roomModerateBalanced, still bullish20%+ OTMLarge roomLow premiumVery bullish, light hedge

Example: Stock at $180

• Conservative: Sell $185 call (2.8% OTM, max premium)
• Moderate: Sell $195 call (8.3% OTM, balanced)
• Aggressive: Sell $210 call (16.7% OTM, keep more upside)

Key decision: How much upside are you willing to sacrifice?

Step 4: Balance Cost (Make It Costless)

The goal: Call premium = Put premium (zero net cost)

Example calculations:

Scenario 1: Perfect balance

• Buy $170 put for $4.00
• Sell $195 call for $4.00
• Net cost: $0 (costless collar)

Scenario 2: Net debit

• Buy $175 put for $5.00 (more protection)
• Sell $200 call for $3.00 (more upside)
• Net cost: $2.00 ($200 debit)
• Paying for better protection

Scenario 3: Net credit

• Buy $165 put for $2.50 (less protection)
• Sell $190 call for $4.50 (less upside)
• Net credit: $2.00 ($200 credit)
• Getting paid to collar

Most common: Aim for zero cost or small debit (<$1.00).

Step 5: Choose Expiration

• 30-60 DTE: Short-term protection (through earnings)
• 90-180 DTE: Medium-term protection (3-6 months)
• 365+ DTE (LEAPS): Long-term protection (year+)

Recommended: 60-90 days for most situations, 180+ days if concerned about extended weakness.

Step 6: Execute the Trade

1. Ensure you own shares first
2. Enter put and call as single order (both legs)
3. Use limit order on net debit or credit
4. Example: Set limit at $0.10 debit if target is costless

Risk and Reward Breakdown

Maximum Loss (Protected Downside)

Formula: (Stock Price - Put Strike) + Net Debit - Net Credit

Example 1: Costless collar

• Stock at $180, own from $120
• Buy $170 put / Sell $195 call for $0 net
• Stock crashes to $100
• Loss limited to: ($180 - $170) = $10/share = $1,000
• Without collar: Would have lost $80/share = $8,000

Example 2: With net debit

• Same setup but paid $2.00 net debit
• Max loss: $10 + $2 = $12/share = $1,200

Maximum Profit (Capped Upside)

Formula: (Call Strike - Stock Price) + Net Credit - Net Debit

Example 1: Costless collar

• Stock at $180
• Sell $195 call / Buy $170 put for $0 net
• Stock rises to $220
• Profit capped at: ($195 - $180) = $15/share = $1,500
• Without collar: Would have gained $40/share = $4,000

Example 2: With net credit

• Same setup but collected $2.00 net credit
• Max profit: $15 + $2 = $17/share = $1,700

Breakeven

With original cost basis:

Example:

• Bought stock at $120
• Collared at $180 for $0 net cost
• Downside protected at $170
• Loss from $120 cost basis: $50/share if put assigned
• But prevented loss of $80/share if stock crashed to $100

Key insight: Collar protects unrealized gains, not necessarily your original cost basis.

Profit and Loss Zones

Example: Stock at $180, collar $170/$195 for $0 net cost

Real Trade Example

Setup: NVDA Gains Protection

• Own 200 NVDA shares, bought at $400
• Now at $900, unrealized gain: $100k
• Earnings in 60 days, uncertain outcome
• Want to protect gains through earnings
• Still bullish long-term, don't want to sell

Trade:

• Buy $850 put (5.6% OTM) for $45.00 = -$9,000
• Sell $1,000 call (11% OTM) for $45.00 = +$9,000
• Net cost: $0 (costless collar)
• 2 collars for 200 shares
• Protected range: $850-$1,000

Outcomes:

Scenario 1: Earnings disappoint, NVDA drops to $750

• Without collar: Loss = ($900-$750) × 200 = -$30,000
• With collar: Loss = ($900-$850) × 200 = -$10,000
• Collar saved $20,000

Scenario 2: Earnings beat, NVDA rises to $1,100

• Without collar: Gain = ($1,100-$900) × 200 = +$40,000
• With collar: Gain = ($1,000-$900) × 200 = +$20,000
• Gave up $20,000 in upside

Scenario 3: No major move, NVDA at $920

• Gain: ($920-$900) × 200 = +$4,000
• Collar cost: $0
• Net: +$4,000, same as without collar

Actual outcome:

• NVDA beat earnings, rose to $980
• Called away at $1,000
• Profit: ($1,000-$900) × 200 = $20,000
• Happy to take 11% gain with protection

The Greeks: How They Affect Collars

Delta: Reduced Directional Exposure

Collars have lower delta than owning stock alone.

Example:

• Long 100 shares: +100 delta
• Long $170 put: +30 delta (protective)
• Short $195 call: -30 delta (caps upside)
• Net position delta: +40

Meaning: You only capture 40% of moves. Protected downside, capped upside.

Theta: Near Neutral

Theta mostly cancels out:

• Long put loses value daily (negative theta)
• Short call loses value daily (positive theta)
• Net theta: Near zero

Result: Time decay is not a major factor in collar profitability.

Vega: Slightly Negative

Impact: Collars benefit slightly from falling IV.

• Long put gains from rising IV
• Short call loses from rising IV (hurts you more)
• Net vega: Slightly negative

Strategy: Collars work better after IV spikes (expensive puts, can collect more on calls).

Managing Collars

Before Expiration (Stock in Range)

If stock stays between strikes:

Option 1: Let Expire

• Both options expire worthless
• Keep stock, collar protection ends
• Start new collar if desired

Option 2: Close Early

• Buy back collar for small debit
• Remove restrictions
• Free stock for upside

Option 3: Roll Forward

• Close current collar
• Open new collar with later expiration
• Extends protection

If Stock Approaches Put Strike

Stock dropping toward downside protection:

Option 1: Let Put Protect You

• Put goes ITM, protects losses
• Losses capped at put strike
• This is why you have the collar

Option 2: Roll Put Down

• Buy back current put
• Sell new put at lower strike
• Lowers protection but might collect credit

Option 3: Close Collar, Exit Stock

• Thesis broken, stock declining
• Close collar, sell shares
• Accept loss, move on

If Stock Approaches Call Strike

Stock rising toward upside cap:

Option 1: Accept Assignment

• Let shares get called away
• Take profit at call strike
• This was max profit scenario

Option 2: Roll Call Up and Out

• Buy back current call (expensive now)
• Sell higher strike call, later expiration
• Extends upside potential
• Usually costs debit

Example:

• Stock at $193, approaching $195 call
• Buy back $195 call for $5.00
• Sell $210 call (90 DTE) for $4.00
• Net cost: $1.00 ($100)
• New upside: $210 instead of $195

Option 3: Close Collar, Keep Stock

• Buy back call, close put
• Free stock for unlimited upside
• Usually costs significant debit

Collar Variations

Zero-Cost Collar (Costless)

Standard setup:

• Call premium = Put premium exactly
• No net cost to establish
• Most common approach

Example:

• Buy $95 put for $3.50
• Sell $110 call for $3.50
• Net: $0

Debit Collar (More Protection)

Paying for better protection:

• Put strike higher (closer to stock price)
• Call strike higher (more upside room)
• Pay net debit for better risk-reward

Example:

• Buy $98 put for $5.00 (better protection)
• Sell $115 call for $2.50 (more upside)
• Net debit: $2.50 ($250)

Use when: Very concerned about downside, willing to pay.

Credit Collar (Less Protection)

Getting paid to collar:

• Put strike lower (less protection)
• Call strike lower (less upside)
• Collect net credit

Example:

• Buy $90 put for $2.00 (minimal protection)
• Sell $105 call for $4.00 (tight cap)
• Net credit: $2.00 ($200)

Use when: Want income, less concerned about downside.

Tax Considerations

Holding Period Impact

Important: Collars can affect your long-term capital gains treatment.

IRS Rule:

• If you hold stock <1 year and add collar
• Holding period may be suspended or reset
• Could convert would-be long-term gains to short-term

Safe harbor:

• Collar more than 30 days OTM on both sides
• Generally doesn't affect holding period

Example problem:

• Bought stock 11 months ago
• Add collar with 5% OTM strikes
• Holding period suspends
• Could delay long-term capital gains qualification

Solution: Consult tax advisor before collaring positions near 1-year mark.

Constructive Sale Rules

Be careful:

• Very tight collars (1-2% OTM both sides)
• IRS might consider "constructive sale"
• Could trigger immediate capital gains tax

General rule: Keep strikes at least 5-10% OTM to avoid issues.

Common Use Cases for Collars

Protecting Windfall Gains

Scenario:

• Stock went from $50 to $200
• Huge unrealized gain
• Want to hold long-term but nervous

Solution: Collar to lock in most gains.

Pre-Earnings Protection

Scenario:

• Own stock with earnings next month
• Historically volatile on earnings
• Don't want to sell before event

Solution: 45-60 DTE collar through earnings.

Market Uncertainty Hedging

Scenario:

• Bull market running hot
• Recession fears increasing
• Own multiple stock positions

Solution: Collar largest positions to reduce portfolio risk.

Executive Compensation

Scenario:

• Executive owns large position in company stock
• Restricted from selling (insider)
• Wants downside protection

Solution: Collar (if allowed by company policy).

Tax-Deferred Selling

Scenario:

• Want to sell but it's December
• Waiting until January for tax purposes
• Worried about decline

Solution: Collar in December, sell in January.

Position Sizing for Collars

Unlike other strategies, position sizing is determined by existing stock position.

Formula: Number of Shares Owned ÷ 100 = Number of Collars

Examples:

• Own 100 shares → 1 collar
• Own 500 shares → 5 collars
• Own 250 shares → 2 collars (collar 200 shares, leave 50 unprotected)

Partial collaring:

• Own 1,000 shares
• Collar only 500 (50%)
• Keep 500 uncapped for upside
• Common when moderately concerned

Common Mistakes

1. Collaring Stock You Don't Want to Own

❌ Stock declining, collar it hoping for recovery

✅ Thesis broken, should just sell

Fix: Only collar positions you want to hold long-term

2. Strikes Too Tight

❌ Stock at $100, use $98/$102 collar

✅ Called away on tiny move, minimal protection

Fix: Use 5-10% range minimum for meaningful protection and upside

3. Not Rolling Call When Stock Rises

❌ Stock at $108, $110 call getting assigned

✅ Missing continued upside move

Fix: Roll call up if you want to keep position

4. Forgetting About Tax Impact

❌ Collar right before 1-year mark

✅ Suspended holding period, lost long-term gains

Fix: Consult tax advisor on timing

5. Paying Too Much for Collar

❌ Paying $5.00 net debit for collar

✅ Better to just buy put alone

Fix: Keep net cost under $1-2 or make it costless

Quick Setup Checklist

Before entering any collar:

✅ Own 100+ shares of underlying stock

✅ Want to hold stock long-term (not selling)

✅ Have unrealized gains worth protecting

✅ Select put strike based on tolerable downside (5-15% OTM)

✅ Select call strike based on acceptable upside cap (10-20% OTM)

✅ Balance to near-zero cost or small debit

✅ Expiration 60-180 DTE for adequate protection period

✅ Consider tax implications on holding period

✅ Have plan for rolling or managing at expiration

✅ Understand you're capping upside for protection

Key Takeaways

• Collars combine long stock, long put (protection), short call (premium collection)
• Max loss = stock price - put strike + net cost (protected downside)
• Max profit = call strike - stock price + net credit (capped upside)
• Best for protecting unrealized gains without selling
• Zero-cost or low-cost by using call premium to fund put
• Reduces both risk AND reward—defined range outcome
• Ideal for uncertain periods: earnings, market volatility, portfolio hedging
• Time decay largely neutral (theta cancels out)
• Tax considerations important—can affect holding period
• Position size determined by shares owned, not account size
