A strangle is a volatility strategy that buys an out-of-the-money call and an out-of-the-money put at different strikes, offering cheaper exposure to big moves than a straddle.
Why Strangles Matter
Straddles are expensive because you buy ATM calls/puts with all premium as time value. Strangles are cheaper because you buy OTM calls/puts with lower vega and gamma.
Cost difference:
Straddle (ATM call + ATM put): 0.0110 (110 pips) Strangle (call +50, put -50): 0.0060 (60 pips)
The strangle costs 45% less. The tradeoff: It needs a larger move to profit.
This makes strangles ideal when:
- IV is high (premiums are expensive; strangle saves cost)
- You expect moderate volatility (not huge moves)
- You want to scale multiple positions
How Strangles Work
Long Strangle (Buy Call + Buy Put at different strikes):
- Current price: 1.0850
- Buy call at 1.0900 (50 pips OTM): Premium 0.0020
- Buy put at 1.0800 (50 pips OTM): Premium 0.0020
- Total cost: 0.0040 (40 pips)
Profit scenarios:
- Price rallies to 1.0950: Call worth 0.0050, put worth 0. Profit: 0.0010
- Price rallies to 1.1000: Call worth 0.0100, put worth 0. Profit: 0.0060
- Price falls to 1.0750: Put worth 0.0050, call worth 0. Profit: 0.0010
- Price falls to 1.0700: Put worth 0.0100, call worth 0. Profit: 0.0060
Loss scenario:
- Price stays at 1.0850: Both expire worthless. Loss: 0.0040 (full cost)
The strangle breaks even at 1.0810 (down 40 pips) and 1.0890 (up 40 pips). Much tighter than a straddle’s 110-pip breakeven.
Strangle vs. Straddle: Side-by-Side
EURUSD at 1.0850, 30 days to expiration
| Strategy | Strikes | Cost | Required Move | Probability |
|---|---|---|---|---|
| Straddle | 1.0850 C/P | 0.0110 | 110 pips | Lower |
| Strangle | 1.0900 C / 1.0800 P | 0.0040 | 40 pips | Higher |
The strangle requires a 64% smaller move (40 pips vs. 110 pips). This makes strangles more likely to profit—but with smaller profits per pip gained.
When to Buy a Strangle
1. When IV is High
If straddle premium is expensive (0.0150+), buy strangle to save cost.
Example: Post-Brexit anxiety, IV is 35%.
- Straddle: 0.0150
- Strangle: 0.0070 (53% cheaper)
You get similar volatility exposure for half the cost. The downside: Need a larger move, but that’s acceptable since you’re not overpaying.
2. When You Expect Moderate Moves
Not every event triggers 150-pip moves. Some trigger 60-80 pips.
Example: Earnings announcement.
- Expected move: 80 pips
- Straddle breakeven: 110 pips (won’t profit)
- Strangle breakeven: 50 pips (will profit)
The strangle matches the event’s move magnitude better.
3. When Scaling Multiple Positions
A trader might buy 5 strangles (cost: 0.0300) instead of 2 straddles (cost: 0.0220). More positions, more edge capture across events.
4. When IV Expansion Is Expected but Isn’t Certain
- Straddle is leveraged to IV spikes (high vega)
- Strangle is less sensitive to IV (lower vega)
- If you don’t think IV will spike as much, strangle is safer
Strangle Strike Selection
How far OTM should your strangle be?
| Distance from ATM | Cost | Required Move | Use Case |
|---|---|---|---|
| 25 pips | Higher | Smaller | Conservative, lower move required |
| 50 pips | Medium | Moderate | Balanced |
| 100 pips | Lower | Large | Aggressive, lottery-like |
| 200 pips | Very low | Extreme | Extreme volatility plays |
Example with EURUSD at 1.0850:
Tight strangle: Call 1.0875 + Put 1.0825 (25 pips OTM)
- Cost: 0.0070
- Breakeven: 1.0805 and 1.0895 (45 pips)
Wide strangle: Call 1.0950 + Put 1.0750 (100 pips OTM)
- Cost: 0.0015
- Breakeven: 1.0735 and 1.0965 (115 pips)
Tight strangles cost more but need smaller moves (good for moderate events). Wide strangles cost less but need huge moves (good for black swan events or cheap lottery tickets).
Real-World Example: EURUSD Earnings Strangle
Setup:
- EURUSD data release in 2 days
- Current price: 1.0850
- Buy strangle: Call 1.0900 + Put 1.0800
- Call premium: 0.0015
- Put premium: 0.0015
- Total cost: 0.0030 (30 pips)
- Breakeven: 1.0820 and 1.0880
Scenario A (Large move):
- Data beats expectations (positive for EUR)
- EURUSD rallies to 1.0920 (70 pips)
- Call: Bought at 0.0015, now worth 0.0020. Profit: 0.0005
- Put: Worthless
- Net: Loss 0.0010 (below breakeven)
Wait, that’s a loss. Let me recalculate:
- Call at 1.0900 strike, price 1.0920: Worth 0.0020 (intrinsic 0.0020)
- You paid 0.0015 for the call; it’s now worth 0.0020. Profit: 0.0005
- Put is worthless; you lost 0.0015 on it
- Total: Profit 0.0005 - Loss 0.0015 = Loss 0.0010
You need price to move more than 50 pips for the strangle to profit.
Scenario B (Larger move):
- EURUSD rallies to 1.0950 (100 pips)
- Call: Worth 0.0050, paid 0.0015. Profit: 0.0035
- Put: Worthless, paid 0.0015. Loss: 0.0015
- Net: Profit 0.0020 (67% return on 0.0030 cost)
The strangle wins on large moves; breaks even at 50+ pips.
Short Strangle: Selling Volatility
You sell call + put (short strangle), collecting premium.
Example:
- Sell call (strike 1.0900): Collect 0.0020
- Sell put (strike 1.0800): Collect 0.0020
- Total income: 0.0040
Profit: If price stays between 1.0800 and 1.0900, you keep the 0.0040 premium.
Loss: Unlimited above 1.0900 and below 1.0800.
Short strangles are profitable in calm markets, catastrophic in volatile ones. Professionals hedge them with protective spreads or options.
Strangle Adjustments
Unlike a straddle (symmetric), a strangle can be adjusted based on directional bias.
If price rallies:
- Close the put leg early (lock in loss)
- Let the call run
- Convert to a leveraged upside bet
If price falls:
- Close the call leg early (lock in loss)
- Let the put run
- Convert to a leveraged downside bet
This flexibility is a strangle advantage over straddles.
Strangle Mistakes
Mistake 1: Buying strangles when IV is already high
- You buy after IV spikes from 15% to 40%
- Premium is expensive (0.0080)
- IV falls back to 20%
- IV contraction hurts you even if price moves
- Fix: Buy strangles when IV is low, not after spikes
Mistake 2: Choosing strikes too wide
- You buy call at 1.1050 + put at 1.0650 (200 pips total)
- Cost: 0.0010
- You’d need a 200+ pip move to profit
- Historical move: 80 pips
- You consistently lose small amounts
- Fix: Match strangle width to expected move magnitude
Mistake 3: Holding into expiration
- 5 days to expiration, call and put are worth pennies
- Theta has destroyed all value
- You’re holding for a miracle move
- Fix: Exit 3-5 days before expiration if not profitable
Mistake 4: Not managing the losing side
- Price moves 80 pips up, call is profitable, put is worthless
- You hold both, hoping price reverses
- Theta kills the profitable call’s value too
- Fix: Close the losing put; let the call run
Key Takeaway
A strangle is a cheaper volatility play than a straddle. You pay less upfront but need bigger moves to profit. Buy strangles when IV is high (expensive premiums) or when you expect moderate volatility. Sell strangles when you expect calm markets and want to collect premium from theta decay.
Manage the losing side early; don’t let theta destroy winners while holding losers. Understand your required move; if historical volatility doesn’t support it, your edge is weak.
