Strap
Buy 2 ATM Calls + 1 ATM Put — a volatility play with a bullish bias.
The strap is a variation of the long straddle that buys two calls and one put at the same ATM strike. It profits from a large move in either direction but with double the exposure to the upside. It is the strategy of choice when you expect high volatility and lean bullish on the likely direction.
Strategy Structure
Buy 2 ATM Calls + Buy 1 ATM Put at the same strike and expiry.
Profit & Loss Profile
Market Outlook
Volatile with a bullish bias — expecting a large move, more likely up.
When to Use
- You expect high volatility and lean bullish
- You want straddle-like protection but with extra upside punch
- IV is low and you expect a volatility spike
- Ahead of a catalyst you believe skews positive
When to Avoid
- When IV is already very high (overpaying, IV crush risk)
- In range-bound markets
- When you have no directional lean (a plain straddle is cheaper per breakeven)
- Very close to expiry (heavy theta on three long options)
Ideal Conditions
- A big move is expected with an upward lean
- Low IV before an expected volatility expansion
- Ahead of an event likely to be bullish (positive results, dovish policy)
- Enough time for the move to develop
Greeks Impact
Positive delta at entry (two calls outweigh one put) — a built-in bullish tilt.
Positive gamma — amplified on the upside by the second call.
Negative theta — heaviest of the volatility plays since you hold three long options.
Positive vega — strongly benefits from rising IV across all three long legs.
Nifty Example
Setup: Buy 2× 24500 CE at ₹150 each and Buy 1× 24500 PE at ₹140. Total premium = (2 × 150) + 140 = ₹440. Lot size = 75. Total cost = ₹440 × 75 = ₹33,000. Upper breakeven = 24720; lower breakeven = 24060.
If profitable: If Nifty rallies to 24950, the two CEs are worth ₹450 each (₹900), the PE worthless. Profit = (₹900 - ₹440) × 75 = ₹34,500 — far more than a straddle would yield on the same up-move.
If loss: If Nifty pins at 24500 at expiry, all three options decay to intrinsic zero. Max loss = ₹33,000.
Adjustments & Risk Management
- Book profit on one call into a rally and hold the rest for further upside
- Convert toward a straddle by selling one call if the bullish view weakens
- Roll the put to a lower strike to reduce cost after an up-move
- Exit after the event to avoid IV crush on the remaining premium
When to Choose a Strap Over a Straddle
The strap is the answer when you expect volatility but believe the move is more likely to be up than down. By adding a second call, you keep full protection against a fall (via the put) while doubling the payoff if the rally materialises. The upside breakeven is also closer to spot than a plain straddle's, since the two calls share the premium burden on that side.
For Nifty, a strap suits a bullish-but-cautious event view — for instance, ahead of results you expect to be strong, or a policy decision you read as dovish, but where you still want a hedge against a surprise selloff.
Managing the Higher Premium
A strap costs more than a straddle because you buy three options instead of two, and that extra premium means heavier theta decay. The position needs the big move to arrive reasonably soon, or time decay on all three legs will erode the trade.
Discipline matters: take partial profits aggressively on the calls during a rally, and do not hold the full structure through a stall. The strap is built for a fast, directional-with-volatility burst, not a slow grind.
