A protective put costs a premium but leaves all your upside intact and sets a hard downside floor.
A zero-cost collar eliminates that out-of-pocket cost by selling a covered call, but caps your upside at the call strike.
A variable prepaid forward delivers cash upfront today against a future share delivery, deferring the tax event but surrendering most upside and introducing counterparty risk.
All three strategies have meaningful tax implications and potential constructive-sale exposure. Each requires professional legal and tax review before use.
Why concentrated-stock holders need structured hedging
When one stock represents the bulk of your wealth, a standard financial-planning model breaks down. Selling to diversify triggers tax. Doing nothing exposes you to catastrophic drawdowns. Structured hedging strategies occupy the space between those two unpleasant endpoints.
Three instruments dominate this space for equity-compensation holders: protective puts, zero-cost collars, and variable prepaid forwards. They share a goal but differ sharply on cost, upside retention, tax treatment, and complexity.
Protective put: the baseline
A protective put is the simplest of the three. You buy a put option on the stock you hold. The put gives you the right, not the obligation, to sell shares at the strike price through expiration. If the stock falls below the strike, the put gains value and offsets your loss. If the stock rises, you keep all the gain; you lose only the premium.
The cost is the entire trade-off. As an illustrative example: a one-year put struck 10% below the current price on a tech stock with 40% implied volatility might cost roughly 5% to 8% of the position's notional value. Higher volatility, longer tenor, and a higher (closer-to-money) strike all push the cost up.

Zero-cost collar: reduce cost by capping upside
A zero-cost collar layers a covered call on top of the protective put. You sell a call at a higher strike, which generates premium income. When the call premium equals the put premium, the net cost is near zero. In practice "zero-cost" is approximate; the exact strikes and premiums are negotiated to balance the two legs.
The floor works the same as a stand-alone put: you are protected below the put strike. The cap is the new constraint: if the stock rises above the call strike, you are obligated to sell (or deliver) shares at the call strike, forfeiting gains above that level.
A collar is appropriate when the cost of a stand-alone put feels prohibitive and you are willing to accept a cap on your upside in exchange. It works best if you are confident the stock will not make a large move up, or if you would be comfortable selling at the call strike anyway.
Tax note on collars: a collar that substantially eliminates the risk of loss and opportunity for gain may be treated as a constructive sale under IRC Section 1259, triggering a taxable event. Whether a specific collar crosses that threshold depends on the strike levels and structure. Consult a tax professional before entering a collar on a low-basis position.
Variable prepaid forward: cash today, shares later
A variable prepaid forward (VPF) is a contract with a financial counterparty (typically an investment bank). You agree to deliver shares, or the cash equivalent, at a future date. In exchange, you receive an advance payment today, typically representing 75% to 90% of the stock's current value (illustrative range; actual terms vary by bank and position size).
The number of shares you deliver at settlement varies based on where the stock price ends up: if the stock is below a floor price, you deliver fewer shares (or more cash); if it is above a cap price, you deliver a fixed maximum. You keep modest downside protection and retain upside up to the cap, but beyond the cap all additional gains accrue to the counterparty.
The primary appeal of a VPF is liquidity: you access a large portion of the position's value now without a current taxable sale, because the transaction is structured as a forward rather than a spot sale. The tax deferral is the key benefit.
Tax note on VPFs: VPFs are subject to constructive-sale analysis under Section 1259 and related rules. Structures that too closely eliminate risk of loss and opportunity for gain risk being recharacterized as a current sale. The IRS has challenged aggressive VPF structures. This is not a do-it-yourself instrument. Consult a securities attorney and CPA before proceeding.
Side-by-side comparison
| Factor | Protective Put | Zero-Cost Collar | Variable Prepaid Forward |
|---|---|---|---|
| Out-of-pocket cost | Premium paid upfront | Near zero (call premium offsets put premium) | Zero; you receive cash upfront |
| Downside floor? | Hard floor at put strike | Floor at put strike | Partial floor; exposure varies by structure |
| Keeps upside? | All upside retained | Capped at call strike; gains above are lost | Limited; capped at forward's upper price |
| Liquidity provided? | No (stock stays held) | No (stock stays held) | Yes: large cash advance at inception |
| Tax / constructive sale risk | Lower (single option; carefully structured puts rarely trigger Section 1259) | Moderate (collar structure can trigger constructive sale if too tight) | Higher (complex IRS scrutiny; must be carefully structured) |
| Counterparty required? | Exchange-traded; no single counterparty | Can be exchange-traded or OTC | Investment bank required; bespoke OTC contract |
| Minimums | None beyond broker requirements | None beyond broker requirements | Typically $5M+ in stock; varies by bank |
| Complexity | Moderate: options approval needed | Moderate-high: two-leg strategy; tax review needed | Very high: bespoke contract, legal, tax, and bank relationship required |
Decision framework: which fits your situation?
Choose a protective put if: you want a simple hard floor, full upside retention, no counterparty exposure, and are willing to pay a premium. Best for near-term specific risk windows (earnings, lockup expiry) or when you have high conviction in the stock.
Choose a collar if: the put cost feels too high and you are comfortable accepting a cap. Best when you would be willing to sell at the cap price anyway, or when your financial plan does not depend on the stock exceeding the call strike. Get a tax opinion first on any low-basis position.
Consider a VPF if: you need liquidity now but do not want a current taxable sale, you have a very large position (typically $5M+), you have access to an investment bank counterparty, and you have engaged a securities attorney and CPA who are experienced in these structures. This is not a retail product.

Frequently asked questions
A VPF is a contract where you agree to deliver shares (or cash equivalent) to a counterparty at a future date, in exchange for receiving cash upfront today. The number of shares you deliver varies based on where the stock price ends up. You receive a substantial portion of current value now, defer the taxable sale, and give up most upside above a cap price. VPFs are complex transactions typically available only through investment banks and require legal and tax counsel.
A zero-cost collar combines a protective put (floor) with a covered call (cap) on the same stock, structured so the call premium you receive offsets the put premium you pay, resulting in little or no net cost. You are protected below the put strike and can participate in gains up to the call strike, but you give up any upside above the cap. If the stock exceeds the call strike, your shares may be called away.
The IRS constructive-sale rules under Section 1259 are directly relevant to VPFs and collars. Whether a VPF or collar is treated as a constructive sale depends on specific structure and the degree to which it eliminates risk of loss and opportunity for gain. General rules are complex, and outcomes vary. You must work with a tax attorney or CPA experienced in these instruments before entering into any such transaction.
A protective put costs a net premium but leaves all upside uncapped. A collar offsets that premium by selling a covered call, but it caps your upside. If your stock makes a large move up, you participate fully with a put but are capped with a collar. The right choice depends on how much you value retaining upside versus reducing out-of-pocket cost.
A protective put is the simplest and most accessible. It requires only options-trading approval at your brokerage and no minimum beyond what your broker requires. A collar adds a second options leg and the constructive-sale analysis. A VPF is the most complex, requiring a counterparty (typically a major bank) and sophisticated legal and tax documentation.
