SHORT STRADDLE
Overview
Sell both an ATM call and put at the same strike and expiration. You collect maximum premium upfront and profit when the stock barely moves. Above or below your breakeven strikes, losses can be severe — upside risk is unlimited, downside risk is substantial.
What it does
You're collecting both an ATM call premium and an ATM put premium simultaneously — the highest possible credit for a neutral position. If the stock stays within the breakeven range, all that premium is yours. The tradeoff: large moves in either direction can produce severe losses. Maximum profit requires the stock to pin exactly at the strike, but the strategy is profitable across any range within the breakevens.
Structure
sell 1 call + sell 1 put
Setup
- 1.Sell 1 ATM Call.
- 2.Sell 1 ATM Put.
- 3.Same strike and expiration.
Max profit
Total Premium Received. E.g., $9.00 × 100 = $900. Realized only if the stock closes exactly at the strike.
Max loss
Upside: unlimited. Downside: (Strike − Total Premium) × 100 if stock falls to zero. E.g., AAPL: $16,600.
Breakeven
Upper: Strike + Total Premium. Lower: Strike − Total Premium. E.g., $184 and $166.
When to use
When you expect very low volatility and the stock to trade in a tight range. Best after a volatility spike has inflated premiums.
When to avoid
Before earnings, FOMC, or any macro event. Requires active management and is not suitable for beginners.
Example trade
Stock: AAPL at $175 Sell 1 AAPL $175 Call at $5.50 Sell 1 AAPL $175 Put at $5.10 Total Credit: $10.60 ($1,060) Expiration: 30 days Breakeven: $164.40 and $185.60 Max Profit: $1,060 (if AAPL pins at $175) Max Loss: Unlimited above $185.60; substantial below $164.40 If AAPL stays at $177: Full $1,060 profit If AAPL drops to $155: Loss = ($175 - $155 - $10.60) × 100 = -$940
Common mistakes
- ×Not having stop-loss rules defined — a stock gap of 10% can turn a $1,000 gain into a $3,000 loss overnight.
- ×Trading short straddles on individual stocks with upcoming earnings or binary events.
- ×Selling straddles in low-IV environments where the premium collected is too small for the risk.
- ×Not actively monitoring the position — short straddles require daily attention.
- ×Adding to a losing straddle instead of closing it — never average into undefined-risk positions.
FAQ
How do I manage a short straddle that's going against me?
Common approaches: close the losing side and let the winner run; roll the short side further out and away; convert to an iron butterfly by buying wings; take the loss and exit.
What's the probability of profit on a short straddle?
Roughly 68% — the stock must stay within 1 standard deviation of the ATM strike. The 32% loss scenarios, however, can be many multiples of the premium collected.
Can I turn a short straddle into a defined-risk trade?
Yes. Buying OTM wings converts it into an iron butterfly, capping your maximum loss at the cost of a slightly lower credit.
