Bullish Short Seagull Spread

Section: 2.54 | Asset Class: Options | Type: Speculation

Overview

The bullish short seagull spread is a bull call spread financed with a sale of an OTM put option. It amounts to a short position in an OTM put at K1, a long position in an ATM call at K2, and a short position in an OTM call at K3 (K1 < K2 < K3). Ideally, the trade is structured to have zero cost. The trader's outlook is bullish. This is a capital gain strategy.

Construction

  • Sell 1 OTM put option at strike K1 (lowest)
  • Buy 1 ATM call option at strike K2 (middle)
  • Sell 1 OTM call option at strike K3 (highest, K3 > K2 > K1)
  • All same expiry; ideally zero net premium (H = 0)

Net debit or credit H

Payoff Profile

f_T = -(K1 - S_T)+ + (S_T - K2)+ - (S_T - K3)+ - H

Breakeven depends on sign of H:

  • S* = K2 + H (if H > 0)

  • S* = K1 + H (if H < 0)

  • K1 <= S* <= K2 (if H = 0)

  • Max profit: P_max = K3 - K2 - H (if S_T >= K3; bull call spread at max)

  • Max loss: L_max = K1 + H (if stock goes to zero; full loss on short put)

Key Conditions / Signals

  • Bullish outlook; expects stock to rise above K2 toward K3
  • Ideally zero-cost (H = 0): the short put premium finances the bull call spread
  • Short put at K1 creates downside exposure below K1

Notes

The seagull spread's name comes from its payoff diagram shape. The upside is capped at K3 - K2 - H. The short put at K1 adds risk if the stock falls sharply, but at zero cost it provides a funded bullish position. Unlike the long combo, there is a defined maximum profit.
