Characteristics

A strangle, requires the investor to simultaneously buy or sell both a call and a put option on the same underlying security. The strike price for the call and put contracts are usually, respectively, above and below the current price of the underlying.


Long strangles

The owner of a long strangle makes a profit if the underlying price moves far away from the current price, either above or below. Thus, an investor may take a long strangle position if they think the underlying security is highly volatile, but does not know which direction it is going to move. This position is a limited risk, since the most a purchaser may lose is the cost of both options. At the same time, there is unlimited profit potential.


Short strangles

Short strangles have unlimited losses, and limited potential gains; however, they have a high probability of being profitable. The assumption of the short seller is neutral, in that the seller would hope that the trade would expire worthless in-between the two contracts, thereby receiving their maximum profit. Short strangles are known to exhibit asymmetrical risk profiles, with larger possible maximum losses being observed compared than the maximum gains to the upside. Active management may be required if a short strangle has become unprofitable. If a strangle trade has gone wrong and has become biased in one direction, a seller might add additional puts or calls against the position, in order to restore their original neutral exposure. Another strategy to manage strangles could be to roll or close the position before expiration; as an example, strangles managed at 21 days-to-expiration are known to exhibit less negative tail risk, and a lower standard deviation of returns.
