Long Strangle

Section: 2.23 | Asset Class: Options | Type: Volatility

Overview

The long strangle is a volatility strategy consisting of a long position in an OTM call option with strike K1 and a long position in an OTM put option with strike K2 (K2 < K1). This is a net debit trade. Because both options are OTM, this strategy is less costly to establish than a long straddle. The flipside is that the move required to reach a breakeven point is more significant. The trader's outlook is neutral. This is a capital gain strategy.

Construction

  • Buy 1 OTM call option at strike K1
  • Buy 1 OTM put option at strike K2 (K2 < K1), same expiry

Net debit: D

Payoff Profile

f_T = (S_T - K1)+ + (K2 - S_T)+ - D

  • Upper breakeven: S*_up = K1 + D
  • Lower breakeven: S*_down = K2 - D
  • Max profit: P_max = unlimited (stock can move far in either direction)
  • Max loss: L_max = D (if K2 <= S_T <= K1 at expiry; both options expire worthless)

Key Conditions / Signals

  • Neutral directional view; expects a very large move but uncertain of direction
  • Cheaper than a straddle but requires a larger price movement to profit
  • Ideal before high-impact events where an extreme move is anticipated

Notes

The maximum loss zone is the range [K2, K1] where both options expire worthless. The position is long vega and short theta. Compared to a straddle, the strangle is cheaper to enter but needs a bigger move to profit.
