A long strangle is a volatility-seeking strategy that uses out-of-the-money options to reduce cost compared to a straddle, at the expense of requiring a larger move to become profitable. You buy an OTM call above the current price and an OTM put below it—both with the same expiration. The trade profits from a large move in either direction, but the move must be more substantial than a straddle requires because the options start further from the money.
The primary advantage of a strangle over a straddle is cost. Because both options are OTM, each is cheaper individually, making the total premium paid lower. This means the maximum loss if the stock stays flat is smaller. The trade-off is that both breakeven points are further from the current price—the stock needs a larger percentage move to reach profitability.
Strangles are particularly effective on stocks with a history of large post-event moves—biotechs before FDA decisions, earnings-driven stocks with a track record of exceeding implied moves, or any asset where you expect a high-magnitude move but are uncertain of direction. Choosing OTM strikes that match your expected move range is the key sizing decision.
Like straddles, strangles suffer from time decay and IV crush after events. Entering a strangle 1-2 weeks before an anticipated catalyst gives enough time for the trade to develop while limiting the exposure to slow theta bleed. Managing winners early—at 50% of the entry premium—is common because the remaining profit requires the stock to stay at extreme levels.
The strangle is sometimes preferred by traders who want to be positioned before a catalyst without paying the full ATM premium of a straddle. If you believe the stock will move dramatically but are uncertain about the exact magnitude, the lower-cost strangle provides leveraged exposure to large moves while capping losses at a lower absolute dollar amount than the equivalent straddle.
