Strap is a bullish volatility play: profit from big moves in either direction, with more upside if price rises.
What is a Strap?
Buy 2 calls + 1 put at the same strike and expiration
Asymmetric exposure: 2x upside, 1x downside
Limited cost (premiums), unlimited profit potential
Why use it?
Expect volatility with a bullish bias
Want asymmetric upside exposure
Accept higher premium cost for the structure
Strap = 2 Calls + 1 Put (Same Strike)
Example:
Buy 2 ETH $3,000 calls (30 days)
Buy 1 ETH $3,000 put (30 days)
Same expiration, same strike
The Math:
Let's say each call premium = $150
Let's say each put premium = $100
Total cost = (2 × $150) + (1 × $100) = $400
For 10 ETH worth:
10 Strap positions = $4,000 total premium
Maximum loss = $4,000 (if price stays flat)
Controls $30,000 worth of ETH exposure (2x calls)
1. High volatility with bullish bias
Expect a big move, prefer upside
Events: upgrades, major announcements, protocol launches
2. Asymmetric upside exposure
Want 2x call exposure vs 1x put exposure
More profit if price rises than if it falls
3. Volatility play with direction preference
Similar to Straddle, but tilted bullish
Accept higher cost than a single call for volatility exposure
Scenario 1: Price Rises Sharply (30% Move)
ETH at $3,000 → $3,900 (30% move)
Call Legs (2x exposure):
Profit per call = ($3,900 - $3,000) = $900
2 calls profit = $900 × 2 = $1,800 per ETH
10 ETH = $18,000 profit from calls
Put Leg:
Expires worthless (price above strike)
Loss = $100 premium per ETH
10 ETH = $1,000 loss from put
Net Result:
Gross profit: $18,000
Premium paid: $4,000
Net profit: $14,000
ROI: 350%
Comparison:
If you bought 10 ETH instead: $3,000 → $3,900 = $9,000 profit (30% gain)
With Strap: $4,000 → $18,000 = $14,000 profit (350% ROI)
1.56x more profit with 7.5x less capital
Scenario 2: Price Rises Moderately (20% Move)
ETH at $3,000 → $3,600 (20% move)
Call Legs (2x exposure):
Profit per call = ($3,600 - $3,000) = $600
2 calls profit = $600 × 2 = $1,200 per ETH
10 ETH = $12,000 profit from calls
Put Leg:
Expires worthless
Loss = $100 premium per ETH
10 ETH = $1,000 loss from put
Net Result:
Gross profit: $12,000
Premium paid: $4,000
Net profit: $8,000
ROI: 200%
Scenario 3: Price Falls Sharply (20% Move)
ETH at $3,000 → $2,400 (20% move)
Call Legs:
Expire worthless
Loss = $300 per ETH
10 ETH = $3,000 loss from calls
Put Leg:
Profit = ($3,000 - $2,400) = $600 per ETH
10 ETH = $6,000 profit from put
Net Result:
Gross profit: $6,000
Premium paid: $4,000
Net profit: $2,000
ROI: 50%
Scenario 4: Price Stays Flat
ETH at $3,000 → $3,000 (0% move)
All Options:
Expire worthless
Total loss = $4,000 premium paid
ROI: -100%
Strap vs Straddle:
Straddle: 1 call + 1 put (symmetric, lower cost)
Strap: 2 calls + 1 put (bullish tilt, higher cost)
Strap offers 2x upside exposure for bigger moves up
Strap vs Long Call:
Long Call: 1 call, lower cost, no downside protection
Strap: 2 calls + 1 put, higher cost, profits on big moves down too
Strap adds volatility exposure with downside participation
Strap vs Strangle:
Strangle: 1 call + 1 put at different strikes (cheaper, wider break-even)
Strap: 2 calls + 1 put at same strike (higher cost, tighter break-even, more upside)
Strap is more directional; Strangle is more neutral
Strap vs Buying ETH:
Buy 10 ETH: $30,000 capital, 30% move = $9,000 profit (30% ROI)
Strap: $4,000 capital, 30% move = $14,000 profit (350% ROI)
7.5x less capital, 1.56x more profit
Maximum Loss:
Limited to premium paid
Occurs if price stays near strike at expiration
Time Decay:
All options lose value over time
Needs a significant move before expiration
Break-Even Points:
Upside Break-Even: Need to cover total premium ($400) with 2 calls
Each call must profit $200 to break even
Break-even = $3,000 + ($400 / 2) = $3,200
Downside Break-Even: Need to cover total premium ($400) with 1 put
Put must profit $400
Break-even = $3,000 - $400 = $2,600
Price Range: Must move beyond $2,600-$3,200 to profit
Capital Efficiency:
Higher premium than single calls
Provides volatility exposure with bullish bias
2x call leverage amplifies upside moves
Strike Selection:
ATM: Highest premium, tightest break-even
OTM: Lower premium, requires larger moves
Expiration Timing:
Longer expiration = higher premium, more time for moves
Shorter expiration = lower premium, needs faster moves
Volatility Environment:
High IV: Higher premiums, but moves may be priced in
Low IV: Lower premiums, potential for volatility expansion
