What is a Short Strangle?
A short strangle is when you sell an out-of-the-money call and an out-of-the-money put on the same stock with the same expiration. You collect premium from both sides and profit when the stock stays between your two strikes. Compared to a short straddle, the strangle gives you a wider profit zone because the strikes are further apart, but you collect less premium.
This is one of the most popular strategies among professional options sellers. The wide profit zone and high probability of success make it attractive for consistent income. The catch is that risk is unlimited on both sides.
How to Set It Up
- Sell 1 OTM put below the current price
- Sell 1 OTM call above the current price
- Same expiration for both
- Strike selection: Many traders use the 15-20 delta range for both strikes. This gives you roughly a 70% probability of profit.
- Expiration: 30-45 days out. This is the optimal range for premium collection and time decay.
The total premium collected is your max profit. Both options need to expire worthless for you to keep it all.
When to Use This Strategy
Use a short strangle when:
- You expect the stock to stay within a range
- Implied volatility is elevated, making premiums rich
- You want a high probability of profit trade
- There are no major catalysts before expiration
- You are comfortable with undefined risk and active management
Short strangles are at their best when IV is high and you expect it to drop. The combination of IV contraction and time decay can make both options decay rapidly.
Example Trade
Stock XYZ is trading at $100. IV is elevated.
- Sell 1 XYZ $90 put for $1.80
- Sell 1 XYZ $110 call for $1.50
- Total premium: $3.30 x 100 = $330 collected
- Breakeven: $90 - $3.30 = $86.70 (downside) / $110 + $3.30 = $113.30 (upside)
- Profit zone: $86.70 to $113.30 — a $26.60 range
Scenario 1: XYZ stays between $90 and $110. Both options expire worthless. You keep the full $330.
Scenario 2: XYZ goes to $115. The call is worth $5. The put expires worthless. Loss: $500 - $330 = $170 loss.
Scenario 3: XYZ drops to $80. The put is worth $10. The call expires worthless. Loss: $1,000 - $330 = $670 loss.
Risk and Reward
- Max profit: Total premium received. $330 in our example. Achieved when the stock stays between both strikes at expiration.
- Max loss: Unlimited on the upside, substantial on the downside. Losses can grow quickly past the breakeven points.
- Breakeven: Two points. Put strike minus total premium ($86.70) and call strike plus total premium ($113.30).
The probability of profit on a well-placed strangle is typically 65-75%. You win more often, but the losses when they happen can be multiples of the premium collected.
Tips and Common Mistakes
- Manage winners early. Close at 50% of max profit. If you collected $330, buy the strangle back for $165 and move on.
- Set a loss limit. Close if the loss reaches 1.5-2x the premium collected. In our example, close at around a $500-$660 loss.
- Do not let it go to expiration. Close 7-10 days before expiration to avoid gamma risk and pin risk.
- Do not fight a trending stock. If the stock is trending hard in one direction, close or adjust the tested side.
- Consider an iron condor for defined risk. Adding protective wings turns this into an iron condor with capped losses.
