# Bear Call Spread
|
|
|
|
**Section**: 2.8 | **Asset Class**: Options | **Type**: Income
|
|
|
|
## Overview
|
|
The bear call spread is a vertical spread consisting of a long position in an OTM call option with strike K1, and a short position in another OTM call option with a lower strike K2 (K2 < K1). This is a net credit trade. The trader's outlook is bearish. This is an income strategy.
|
|
|
|
## Construction
|
|
- Buy 1 call option at strike K1 (higher OTM), same expiry
|
|
- Sell 1 call option at strike K2 (lower OTM, K2 < K1)
|
|
|
|
Net credit: C = premium received for K2 call - premium paid for K1 call
|
|
|
|
## Payoff Profile
|
|
f_T = (S_T - K1)+ - (S_T - K2)+ + C
|
|
|
|
- Breakeven: S* = K2 + C
|
|
- Max profit: P_max = C (if S_T <= K2 at expiry; both calls expire worthless)
|
|
- Max loss: L_max = K1 - K2 - C (if S_T >= K1 at expiry)
|
|
|
|
## Key Conditions / Signals
|
|
- Bearish to neutral outlook; expects stock to remain below K2 by expiry
|
|
- Prefer when implied volatility is elevated (larger credit received)
|
|
- Income generation with defined upside risk
|
|
|
|
## Notes
|
|
The bear call 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 call at K1 caps the loss relative to a naked short call.
