Protective Collar Strategy

Protective collar strategy is an option hedge that pairs downside protection with capped upside. EP90 从美加墨世界杯看懂期权—华尔街的终极武器 explains it through Mark Cuban’s locked-up Yahoo-stock case: buy puts to set a floor, sell calls to help pay for the puts, and accept that gains above the call strike are given away.

The episode frames the collar as a wealth-preservation tool rather than a return maximization tool. It is most useful when concentrated paper wealth, lockups, taxes, liquidity, or life-changing downside make survival more important than squeezing out every possible upside dollar.

Key Claims

• A long put sets a downside floor for the protected asset.
• A short call funds some or all of the put cost but caps upside above the call strike.
• The strategy can be close to zero-cost in premium terms while still carrying opportunity cost.
• The main tradeoff is explicit: exchange unlimited upside for known downside protection.
• Collars are most relevant when the investor has concentrated exposure and cannot or should not simply sell the asset immediately.
