Fence (Options)
A Fence is an options hedging strategy in which a stock owner buys a protective put and sells an out-of-the-money call, bounding the portfolio outcome between a floor and a ceiling — protecting against downside while capping upside participation.
The Fence, also widely known as a Collar, is one of the most practical hedging structures available to equity investors. It is especially popular with executives holding concentrated stock positions, portfolio managers seeking downside protection without selling holdings, and long-term investors approaching retirement who want to reduce equity risk without triggering capital gains taxes.
The mechanics involve three components: owning the underlying stock, purchasing a put option below the current stock price (the floor), and selling a call option above the current stock price (the ceiling). The premium received from the sold call offsets the cost of the purchased put, often allowing the hedge to be established at minimal or zero net cost when the strikes are selected appropriately.
The outcome at expiration is bounded: if the stock falls below the put strike, the put is exercised and the investor exits at the floor price regardless of how far the stock has fallen. If the stock rises above the call strike, the call is assigned and the investor delivers shares at the ceiling price, forgoing any gains above that level. Between the two strikes, the investor retains full profit and loss exposure.
For tax-deferred hedging purposes, the fence is particularly valuable. By structuring the fence to avoid triggering constructive sale rules under IRS Section 1259 (which applies when the hedge is so tight that economic risk is substantially eliminated), an investor can defer capital gains while still protecting most of the portfolio value. Typically this requires the put strike to be at or below the current stock price and the call strike to be well above it.
Implied volatility skew affects the economics of fences. Expensive put skew means put protection costs more, while elevated call premiums provide better upside financing. In high-volatility markets, fences can often be established at attractive terms.
Corporate insiders frequently use fences as a substitute for selling shares they are restricted from selling during lock-up periods, achieving economic neutrality while maintaining legal ownership of the shares.
