Collar Strategy
A defensive strategy combining stock ownership with protective puts and covered calls. Creates a 'collar' around your position with defined risk and reward. Often implemented at low or zero net cost, making it ideal for protecting gains in concentrated positions without selling shares.

A collar strategy is a three-legged protective structure combining 100 shares of underlying stock with a long out-of-the-money protective put (a downside floor) and a short out-of-the-money call (an upside cap).
By selling the call, you collect premium that directly finances the purchase of the protective put, frequently achieving a zero-cost collar. It is widely favored by corporate executives and institutional investors to protect accumulated gains in concentrated equity positions without triggering immediate taxable sales.
Collar Payoff Boundaries
Worked Example ($100 Stock)
Regardless of how far the stock drops below $90, losses cannot exceed $10/share. In exchange, gains above $110 are surrendered.
Collar vs. Stop-Loss Order
Equity Collar
- Guaranteed protection: put option provides an inviolable floor against overnight gaps and black swan crashes.
- Zero execution slippage: contractual right to sell at the strike.
- Cost: financed entirely by selling the OTM call.
Traditional Stop-Loss Order
- Gap risk vulnerability: order executes at the market open price during weekend gaps, ignoring the stop trigger price.
- False whipsaws: sharp intraday dips can trigger premature sales right before a rebound.
- Cost: free, but lacks contractual protection.
Greeks at a Glance
Delta
Net positive but bounded between 0 and 1 — delta approaches 0 below the put strike and near the call strike.
Theta
Near neutral — short call theta income offsets long protective put theta decay.
Vega
Balanced — long put vega balances short call vega across moderate price ranges.
Greeks Role
Engineered to bracket risk: establishes a guaranteed floor and defined cap on stock equity.

How to Read
Legs are pre-filled with a synthetic long index position, a real ~20-delta protective put, and a real ~20-delta short call from the current SPX chain. Change the expiration or either strike to see the payoff update live. The collar creates a defined range of outcomes: maximum loss occurs at or below the put strike, maximum profit at or above the call strike.
How to Trade It
Strike Selection
- Protective Put: buy a 10–20 delta put (typically 5–15% below current stock price) to establish your worst-case loss floor.
- Covered Call: sell a 20–30 delta call (typically 5–15% above current stock price) priced to match or exceed the put's cost.
- Zero-Cost Objective: adjust the call strike until net credit matches the put debit.
Duration & Expiration
- 60–180 DTE: longer durations reduce annual rebalancing friction and allow wider collar boundaries for the same zero net cost.
Step-by-Step Execution
- Hold 100 shares of underlying stock per collar contract.
- Select a target expiration 60–180 days out.
- Price the desired downside put strike (e.g. -10%).
- Find the call strike that generates equal or higher premium (+10% to +15%).
- Execute the put purchase and call sale simultaneously.
Manage the Position
Position Adjustments
- Rolling Collars Forward: as expiration approaches (within 21–30 DTE), roll both legs to a new expiration cycle to maintain perpetual protection.
- Rolling the Call Up: if the stock rallies strongly towards the call strike and you wish to avoid assignment, buy back the call and roll to a higher strike and later date.
- Exercising the Put: if the company suffers catastrophic breakdown, exercise the put at expiration to exit at the strike price.
Total Position Return at Expiration
Downside Crash Outcome
The protective put cushions 80% of the drop, preventing catastrophic capital loss.
Risks & Common Mistakes
Key Considerations
- Opportunity Regret: if the stock enters a massive multi-bagger rally, upside is capped at the call strike unless rolled for a debit.
- Early Assignment Risk: watch short in-the-money calls closely right before ex-dividend dates to prevent surprise share assignment.
- Trading Wide Bids: on illiquid stock options, wide spreads on both legs can create unnecessary execution slippage.
Risk Disclosure: Collars define maximum profit and maximum loss. While downside risk is limited to the put strike, capital loss is still possible down to that level. This content is for educational purposes only.
