Strangle Options Strategy: Complete Guide
Master the strangle strategy to profit from volatility at a lower cost than straddles. Learn when to buy or sell strangles, how to select optimal strikes, and the professional techniques for managing this versatile options strategy.
What is Strangle Strategy?
Strangle Strategy is an options strategy where you buy or sell out-of-the-money calls and puts simultaneously. Long strangles profit from large price movements in either direction, while short strangles profit from low volatility.
Strangles are similar to straddles but use different strikes, making them cheaper (long) or safer (short).
What is a Strangle Options Strategy?
A strangle is a volatility-based options strategy similar to a straddle, but uses out-of-the-money (OTM) options instead of at-the-money options. You simultaneously buy or sell an OTM call and OTM put at different strike prices with the same expiration date.
There are two types of strangles:
Long Strangle (Buy Strangle)
Construction: Buy 1 OTM call + Buy 1 OTM put
Market Outlook: Expecting a large move but less conviction than straddle
Profit From: Large price swings beyond breakevens or volatility expansion
Risk: Limited to premium paid (lower than straddle)
Best When: IV is low, want cheaper entry than straddle
Short Strangle (Sell Strangle)
Construction: Sell 1 OTM call + Sell 1 OTM put
Market Outlook: Expecting stock to stay range-bound between strikes
Profit From: Time decay and volatility decline when stock stays between strikes
Risk: Unlimited (theoretically)
Best When: IV is high, want higher probability than short straddle
Key Strangle Characteristics
- Lower Cost: 30-50% cheaper than straddles due to OTM options
- Wider Breakevens: Stock must move further to profit vs straddles
- Lower Gamma: Less sensitivity to price movement than straddles
- High Vega: Still very sensitive to volatility changes
- Higher Probability (Short): Wider profit zone than short straddles
Strangle vs Straddle: Key Differences
| Factor | Strangle | Straddle |
|---|---|---|
| Strike Selection | OTM call + OTM put | Both ATM at same strike |
| Cost | 30-50% cheaper | More expensive |
| Breakevens | Wider (harder to profit) | Narrower (easier to profit) |
| Gamma | Lower | Higher |
| Best Use | Lower conviction, budget-conscious | Higher conviction, expect big move |
Long Strangle Strategy: Buy Volatility Cheaper
When to Buy a Strangle
Long strangles are ideal when you want volatility exposure but either have limited capital or less conviction than a straddle warrants:
Ideal Long Strangle Setup
- Catalyst Approaching: Earnings, events, or announcements expected
- Low IV Environment: IV rank below 30th percentile
- Large Expected Move: Historical moves suggest 12%+ is possible
- Strike Selection: Use strikes with 15-20 delta (80-85% OTM probability)
- Time Frame: 2-4 weeks to expiration for earnings plays
Selecting Strangle Strikes
Strike selection is crucial for strangle success:
Common Strike Selection Methods
- Standard Deviation Method: Put at -1 SD, Call at +1 SD (~16 delta each)
- Expected Move Method: Use options-implied expected move for strike placement
- Fixed Delta: Select 15-20 delta options for both sides (80-85% OTM probability)
- Percentage Width: Place strikes 8-10% away from current price
Professional Tip: For earnings plays, set strikes just outside the expected move to balance cost with probability of profit.
Real Example: AAPL Earnings Long Strangle
Trade Setup
Date: January 26, 2024 (5 days before earnings)
Stock Price: $195.00
Implied Volatility: 32% (28th percentile)
Expected Move: ±$11 (5.6%)
Position Construction:
- Buy 1 Feb 2 $185 Put (15 delta) @ $2.20
- Buy 1 Feb 2 $205 Call (15 delta) @ $2.50
- Total Cost: $4.70 per strangle ($470 per contract)
- Strike Width: $20 wide ($185-$205 range)
Breakeven Analysis:
- Upper Breakeven: $205 + $4.70 = $209.70 (+7.5% move required)
- Lower Breakeven: $185 - $4.70 = $180.30 (-7.5% move required)
- Stock must move more than $14.70 (7.5%) to profit
Compare to Straddle:
- $195 Straddle would cost $9.80 (2.1× more expensive)
- Straddle breakevens: $185.20 / $204.80 (5% move needed)
- Strangle saves $5.10 but needs 2.5% more movement
Actual Outcome:
- AAPL beat earnings estimates on Feb 1
- Stock gapped to $210 (+7.7%), then rallied to $212 (+8.7%)
- $205 Call value: $8.20
- $185 Put value: $0.05
- Total Value: $8.25
- Profit: $8.25 - $4.70 = $3.55 per share = $355 (75.5% return)
Why This Worked:
- Stock move (8.7%) exceeded breakeven requirement (7.5%)
- Lower premium cost meant smaller move needed vs straddle (7.5% vs 5%)
- IV was low going in, expanded on earnings surprise
- Strike selection (15 delta) provided good balance of cost vs probability
Short Strangle Strategy: Sell Volatility with Higher Probability
When to Sell a Strangle
Short strangles offer better probability of profit than short straddles, with defined profit zones:
Ideal Short Strangle Conditions
- High IV: IV rank above 75th percentile
- Post-Catalyst: After earnings or major events (volatility crush expected)
- Range-Bound Outlook: Expect consolidation between strikes
- Strike Selection: Sell 15-20 delta options (80-85% probability of expiring OTM)
- Adequate Capital: Margin requirements typically 20-30% of notional
Short Strangle Risk Management
- Position Size: Never risk more than 3-5% of account per strangle
- Stop Losses: Close if stock breaches either strike or loss exceeds credit
- Take Profits Early: Close at 50-65% of max profit
- Monitor Daily: Check position at least twice per day
- Manage Winners: Roll challenged side or close entire position if one side threatened
Understanding Strangle Greeks
| Greek | Long Strangle | Impact |
|---|---|---|
| Delta | Slightly negative | OTM put usually has higher delta magnitude than call initially |
| Gamma | +Moderate | Lower than straddles but still benefits from large moves |
| Theta | -Moderate | Loses less per day than straddles (30-40% less theta decay) |
| Vega | +High | Very sensitive to IV changes, primary profit driver |
Frequently Asked Questions
What is a strangle in options trading?
A strangle is an options strategy where you simultaneously buy (or sell) an out-of-the-money call and an out-of-the-money put at different strike prices but the same expiration. Long strangles profit from large price movements in either direction at a lower cost than straddles, while short strangles profit when the stock stays between the strikes.
What is the difference between a straddle and a strangle?
Straddles use the same ATM strike for both options, while strangles use different OTM strikes. Strangles cost 30-50% less but require larger price moves to profit. Strangles have wider breakevens and lower gamma, making them better for lower-conviction plays or smaller accounts.
When should you buy a strangle?
Buy strangles when expecting a significant move but with less conviction than a straddle trade. Ideal before earnings or events when IV is low and you want to limit premium outlay. Works best when expected moves are 12%+ and you can buy strikes giving 80-90% probability of being OTM.
