Chooser Option
A chooser option is an exotic derivative that grants the holder the right to designate, at a specified choice date before expiration, whether the contract will function as a call option or a put option for the remainder of its life, providing flexibility to benefit from either direction of the underlying move.
The chooser option is structured to handle uncertainty about the direction of an anticipated market move. A trader who knows that a major event — an FDA drug approval decision, a Federal Reserve meeting, an election outcome — will cause significant volatility but is genuinely uncertain about whether prices will spike up or down might purchase a chooser option. On the choice date, once early directional information becomes available, the trader designates the option as a call or a put for the remaining term.
The chooser option is always worth at least as much as both the underlying call and the underlying put at the time of the choice. This is because the choice date value equals the maximum of the call value and the put value at that moment. Before the choice date, the chooser option is more expensive than either the call or put alone because it incorporates the optionality of the choice itself. In the limiting case where the choice date equals the expiration date, the chooser becomes equivalent to a straddle.
Pricing a chooser option involves decomposing it into two simpler options. A standard chooser can be shown to equal a call with the full remaining time to expiration plus a put with time to expiration equal only to the period from the choice date to expiration, adjusted for the present value of dividends. This decomposition allows the chooser to be priced using vanilla option building blocks under certain conditions, though numerical methods are generally used for complex variations.
Chooser options are an OTC product in the United States, traded between dealer banks and institutional counterparties. They appear in structured products and are used around scheduled corporate events, earnings announcements, and macroeconomic data releases where traders want event-driven volatility exposure but prefer to maintain directional flexibility until the last responsible moment. CBOE-listed straddles serve a similar economic purpose for retail and institutional traders who want direction-agnostic event exposure through standardized products.
For practitioners, the chooser occupies a conceptual middle ground between a straddle and a sequential options strategy. It is cheaper than a full straddle because the holder only controls one leg after the choice date, but more expensive than a single directional option because of the embedded right to choose.
