Overview
A long strangle buys an out-of-the-money call and an out-of-the-money put. It is a cheaper version of the long straddle — you pay less premium because both options start out of the money, but you need a larger move to reach profit.
It suits situations where you expect a substantial breakout but want to keep the cost (and the maximum loss) lower than a straddle. Risk is capped at the debit; the payoff is convex once price clears either breakeven.
How it’s built
Buy 1 out-of-the-money call and buy 1 out-of-the-money put, same expiry. The total premium paid is the maximum loss, realised if price stays between the strikes.
| Action | Option | Strike | Premium | Role |
|---|---|---|---|---|
| Buy | Call (CE) | 24,200 | 90 | Buy OTM call |
| Buy | Put (PE) | 23,800 | 80 | Buy OTM put |
Payoff at expiry
The diagram is computed from the legs above on an illustrative NIFTY 50 snapshot — spot 24,000, one lot of 75.
Worked example — NIFTY 50
Expecting a breakout from NIFTY (at 24,000) but unsure of direction, you buy the 24,200 call for 90 and the 23,800 put for 80 — a debit of 170 points (₹12,750 per lot), roughly half the cost of the straddle.
The trade-off is wider breakevens at 23,630 and 24,370 — price must travel further before a leg pays off. Anywhere between the two strikes at expiry leaves both worthless and realises the full (but smaller) loss.
At expiry
| If the market… | Outcome |
|---|---|
| NIFTY breaks out sharply either way | Profit grows with the move |
| NIFTY at 23,630 or 24,370 | Breakeven on either side |
| NIFTY between 23,800–24,200 | Maximum loss — both premiums decay |
Greeks & behaviour
When to use it
- You expect a large breakout but want a cheaper entry than a straddle.
- Implied volatility is low and you anticipate expansion.
- You accept wider breakevens in exchange for a smaller debit.
Risks & caveats
- Needs a bigger move than a straddle to become profitable.
- A range-bound expiry forfeits the entire (smaller) premium.
- Volatility crush after an event can erode value quickly.
Key takeaways
- A lower-cost, wider-breakeven long-volatility play.
- Capped risk, convex reward on a real breakout.
- Pick it over a straddle when you expect a truly large move.
