Strap

A straddle variant with a bullish lean — buy 2 ATM calls and 1 ATM put. Profits from a strong move either way, but more on the upside.

What is this strategy?

The Strap is the bullish mirror of the Strip: buy 2 ATM calls and 1 ATM put. The same concept with a bullish rather than bearish lean.

If the underlying rises you gain twice as fast through the two calls. If it falls you gain only $1 per dollar, through the single put. Useful when you expect a strong move with the probable direction being up — earnings with expected positive guidance, favourable macro events.

Same cost characteristics — roughly 50% more expensive than a straddle — and the same management profile as the Strip, inverted.

Example

SPY at $450. You expect a strong move with a bullish lean. Strap at the 450 strike.

  • Calls Purchased (2× 450) −$1,000 ($500 × 2)
  • Put Purchased (450) −$500
  • Net Debit $1,500
  • Breakeven (upside) $457.50 (450 + 15.00/2, because there are two calls)
  • Breakeven (downside) $435.00 (450 − 15.00)
  • Profit if SPY = $500 +$8,500 (2 calls × $5,000 − $1,500 debit)
  • Profit if SPY = $400 +$3,500 (1 put × $5,000 − $1,500 debit)
  • Maximum Loss $1,500 (the debit) with SPY exactly at $450

Frequently Asked Questions

When should this structure be opened?

How is it managed before expiration?
By closing as soon as the expected move arrives, without letting time erode the position.
Which strategy is it most often confused with?
The strip, its mirror image with a bearish lean.
