SHORT STRANGLE
Overview
Sell an OTM call and OTM put at different strikes in the same expiration. The wider profit zone versus a short straddle provides more breathing room, but you collect less premium. Unlimited upside risk, substantial downside risk — you profit as long as the stock stays between the two short strikes.
What it does
You collect premium from both sides of the market — the sold call generates income above the current price, and the sold put generates income below. You profit as long as the stock stays between both strikes through expiration. Compared to a short straddle, you collect less premium but have a wider profit zone. The risk is that large moves can cause severe losses with no defined cap.
Structure
sell 1 OTM call + sell 1 OTM put
Setup
- 1.Sell 1 OTM Call (above current price).
- 2.Sell 1 OTM Put (below current price).
- 3.Same expiration.
Max profit
Total Premium Received. Realized if the stock closes between the two short strikes at expiration.
Max loss
Upside: unlimited beyond the short call + total premium. Downside: substantial below short put − total premium.
Breakeven
Upper: Short Call Strike + Total Premium. Lower: Short Put Strike − Total Premium.
When to use
When you expect low volatility and the stock to stay within a wide range. Best in high-IV environments after selling the spike.
When to avoid
Before major catalysts. Requires margin and active management — not suitable for beginners.
Example trade
Stock: SPY at $430 Sell 1 SPY $445 Call at $2.80 Sell 1 SPY $415 Put at $2.50 Total Credit: $5.30 ($530) Expiration: 35 days Breakeven: $409.70 and $450.30 Max Profit: $530 (if SPY stays between $415 and $445) Max Loss: Unlimited above $450.30; substantial below $409.70 If SPY stays at $432: Full $530 profit If SPY drops to $395: Loss = ($415 - $395 - $5.30) × 100 = -$1,470
Common mistakes
- ×Treating short strangles as 'safe' — undefined risk means a 10% gap can create losses exceeding a year of premiums.
- ×Selecting strikes too close to the current price to maximize premium, leaving no breathing room.
- ×Not using position sizing rules — short strangles on large positions can blow up accounts.
- ×Ignoring overnight and weekend gap risk — most catastrophic losses occur at the open after news.
- ×Selling strangles on earnings without realizing IV will crush AND the stock will move significantly.
FAQ
What is the difference between a short strangle and a short straddle?
A straddle sells both options at the ATM strike (more premium, narrower profit zone). A strangle sells OTM options (less premium, wider profit zone). Both have undefined risk.
How do I manage an untested side?
Many traders roll the untested (winning) side closer to the current stock price to collect more credit and balance the position's delta.
Can I convert a short strangle to a defined-risk position?
Yes — buy further OTM options (a call above the short call, a put below the short put) to create an iron condor with defined maximum loss.
