Bull Put Spread
Section: 2.7 | Asset Class: Options | Type: Income
Overview
The bull put spread is a vertical spread consisting of a long position in an OTM put option with strike K1, and a short position in another OTM put option with a higher strike K2 (K2 > K1). This is a net credit trade. The trader's outlook is bullish. This is an income strategy.
Construction
- Buy 1 put option at strike K1 (lower OTM), same expiry
- Sell 1 put option at strike K2 (higher OTM, K2 > K1)
Net credit: C = premium received for K2 put - premium paid for K1 put
Payoff Profile
f_T = (K1 - S_T)+ - (K2 - S_T)+ + C
- Breakeven: S* = K2 - C
- Max profit: P_max = C (if S_T >= K2 at expiry; both puts expire worthless)
- Max loss: L_max = K2 - K1 - C (if S_T <= K1 at expiry)
Key Conditions / Signals
- Bullish to neutral outlook; expects stock to remain above K2 by expiry
- Prefer when implied volatility is elevated (larger credit received)
- Income generation with defined downside risk
Notes
The bull put spread is a credit spread. Maximum profit is limited to the net credit received. Maximum loss is the spread width minus the credit. The long put at K1 provides downside protection relative to a naked short put.
