Long Straddle: Profit from Big Moves in Either Direction
A long straddle buys both a call and a put at the same strike (typically ATM) and same expiration. Pays off when the underlying makes a large move in either direction. Max loss = total premium paid. Max gain = unlimited upside, strike-minus-premium downside.
The straddle's break-even points are strike + total premium and strike − total premium. The stock has to move beyond either break-even before expiration for the position to profit. Because you're paying for both directions, total premium is high — and IV rank matters enormously. Buying a straddle at IV rank 90 typically costs more than the realized move ends up being, even when the stock does move significantly. Buying at IV rank 20 has the math heavily in your favor if a move materializes.
Best use cases: pre-earnings on names with binary outcomes where the post-earnings move historically exceeds the implied move; pre-FDA decision biotechs; pre-Fed announcements on rate-sensitive ETFs. Worst use cases: range-bound stocks at high IV (you pay maximum premium for minimum probability of large move). The IV crush after a binary event can destroy a long straddle even if the directional thesis was correct.
Frequently Asked Questions
How big a move do I need to break even?
Both break-evens combined are roughly 2 × the option premium. On a 30 DTE ATM straddle in normal IV, that's typically 5–10% of underlying price.
Long straddle or long strangle?
Straddle (same strike) costs more but has tighter break-evens. Strangle (different strikes) is cheaper but needs a bigger move. Choose strangle when the premium difference matters more than the move size.
