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 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.
