Long Straddle Strategy: How It Works, Formulas, and Examples
The long straddle is the go-to strategy when you expect a large price move but do not know the direction. By buying both a call and a put at the same strike and expiration, you profit from volatility regardless of which way the stock moves.
In this guide
1. What Is a Long Straddle?
A long straddle involves buying one call and one put on the same underlying stock, at the same strike price, with the same expiration date. You pay a premium for both legs upfront.
The call profits if the stock rises sharply. The put profits if the stock falls sharply. Because you hold both, you profit from a large move in either direction — the position is direction-neutral and volatility-long.
The trade has two enemies: time and a lack of movement. Every day that passes without a significant price move, the options lose time value (theta decay). For the straddle to profit, the move must be large enough to offset the total premium paid.
2. Maximum Profit
Maximum profit is theoretically unlimited on the upside (the call has unlimited profit potential as the stock rises) and substantial on the downside (the put profits down to zero).
Upside profit = (Stock Price − Strike − Total Premium) × 100
Downside profit = (Strike − Stock Price − Total Premium) × 100
The larger the price move, the larger the profit. A 20% move on a straddle entered at 5% of the stock price generates a substantial return.
3. Maximum Loss Formula
Maximum loss is limited to the total premium paid for both legs. This occurs when the stock closes exactly at the strike price at expiration — both the call and put expire worthless.
Max Loss = (Call Premium + Put Premium) × 100
4. Two Breakeven Calculations
Upper Breakeven = Strike + Total Premium Paid
Lower Breakeven = Strike − Total Premium Paid
For a profit, the stock must close outside these two breakeven points at expiration. The wider apart the breakevens, the larger the required move — and the more expensive the straddle.
5. Worked Example — Earnings Play
AAPL reports earnings in 2 days. It is trading at $200. You expect a big move but do not know the direction.
Trade Setup
- Buy 1 AAPL $200 call at $4.00
- Buy 1 AAPL $200 put at $3.50
- Total premium paid: $7.50 per share
- Total cost: $7.50 × 100 = $750
Max Loss: $7.50 × 100 = $750
Upper Breakeven: $200 + $7.50 = $207.50
Lower Breakeven: $200 − $7.50 = $192.50
AAPL needs to move more than 3.75% in either direction for the trade to be profitable. If AAPL gaps up to $215 on good earnings, your call is worth approximately $15 — a $750 profit on a $750 investment. If it gaps down to $185, your put is worth approximately $15 — same outcome in the other direction.
6. When to Use a Long Straddle
- •Before earnings. The most common use case. Earnings create binary outcomes — large gap up or large gap down. A straddle profits from either.
- •Before macro events. Fed decisions, CPI prints, geopolitical events — any binary catalyst where direction is uncertain but magnitude is likely large.
- •When implied volatility is low. Low IV means cheaper straddles. You pay less for the options and need a smaller move to break even.
Avoid straddles when implied volatility is already very high — you are paying inflated premiums and the stock may not move enough to overcome the cost. The classic mistake is buying a straddle into earnings when IV is already pricing in the expected move.
