## Direct answer

A **bear call spread**, also called a call credit spread, sells a call at a lower strike and buys a call at a higher strike with the same underlying, expiration, exercise style, settlement, multiplier, and contract quantity. It is normally opened for a net credit and expresses a view that the underlying will remain below the short strike.

At expiration, maximum profit is the initial net credit; maximum contractual loss is `strike width − net credit`, multiplied by the contract multiplier. Upside loss is capped by the long call only while both legs remain intact and settle as expected.

## Payoff and pre-expiration behavior

Let the short-call strike be `K_1`, long-call strike `K_2`, with `K_2 > K_1`, and net credit `C`. The expiration profit per underlying unit is:

`C − max(S_T − K_1, 0) + max(S_T − K_2, 0)`

- If `S_T ≤ K_1`, both calls expire without intrinsic value and profit is `C`.
- If `K_1 < S_T < K_2`, profit declines dollar for dollar as spot rises.
- If `S_T ≥ K_2`, loss is capped at `(K_2 − K_1) − C`.
- Breakeven at expiration is `K_1 + C` before fees.

Before expiration, the spread is not determined only by spot. It generally starts with negative delta, negative gamma, positive theta, and often negative vega, but magnitudes and even some signs vary with spot, time, skew, and rates. A volatility decline or passage of time may help; an upside gap, skew change, or widening bid-ask market may hurt.

The net credit is not “income” when received; it is consideration for an open obligation. Return on maximum risk, probability of any profit, expected return, and annualized return are different measures. A high win rate can coexist with poor outcomes if occasional losses approach the spread width.

American-style short calls may be assigned before expiration, especially when deep in the money near an ex-dividend date and remaining extrinsic value is small. The long call does not exercise itself to offset early assignment. The account may become short shares until the investor acts, creating dividend, borrow, margin, and gap exposure.

## 105/110 call spread example

Suppose the underlying is $100. One 105 call is sold and one 110 call is bought for the same expiration, producing a $1.50 net credit and using a 100-share multiplier.

- Maximum profit: `$1.50 × 100 = $150`.
- Strike width: `$110 − $105 = $5`.
- Maximum contractual loss: `($5 − $1.50) × 100 = $350`.
- Expiration breakeven: `$105 + $1.50 = $106.50`.

At a $103 expiration price, both options have no intrinsic value and profit is $150. At $108, the short call is worth $3 and the long call zero, so profit is `($1.50 − $3) × 100 = −$150`. At $115, the short call is worth $10 and the long call $5; their $5 net value produces the maximum $350 loss.

The headline reward-to-risk is `$150 / $350 ≈ 42.9%`, but that is not a probability or expected return. Fees and the executable combination price reduce it. If closing the spread costs $0.30, profit before fees is `($1.50 − $0.30) × 100 = $120`, not $150.

## Trade and expiration checklist

- Verify both legs have the same underlying, expiration, style, settlement, multiplier, and quantity.
- Calculate credit from executable combination bid/ask, not from adding favorable leg midpoints.
- Convert maximum profit, maximum loss, fees, and stress scenarios into account dollars.
- Check both strikes' liquidity and submit the spread as one limit order where supported.
- Stress an overnight move above the long strike, volatility/skew changes, and spread widening.
- Monitor ex-dividend dates and compare the short call's remaining extrinsic value with the dividend and financing economics.
- Know broker margin, liquidation, exercise, and assignment procedures; requirements may exceed theoretical loss temporarily.
- If assigned early, evaluate the resulting short shares and long call separately before closing or exercising.
- Near expiration, plan for pin risk and after-hours moves; one leg may exercise while the other does not.
- Record adjustments as closing the old position and opening a new one. Rolling does not erase a realized loss.

Closing before expiration can reduce operational risk but may cost more than theoretical value. Holding to expiration can save closing cost but adds exercise, assignment, and uncertain after-hours exposure. The better choice depends on executable prices and account capacity, not a universal rule.

## Common misconceptions

- “The credit is profit on trade date.” It accompanies an unresolved short-option obligation.
- “The strategy profits only if the stock falls.” It reaches maximum profit anywhere at or below the short strike at expiration.
- “Defined loss means no margin or assignment risk.” Temporary stock, dividend, and broker requirements can exceed the payoff diagram's cash flow.
- “The long call automatically protects an early assignment.” It remains a separate contract until sold or exercised.
- “Theta guarantees gains each day.” Gamma, volatility, skew, and price moves can outweigh decay.
- “A 42.9% maximum-risk return means a 42.9% expected return.” It describes payoff magnitude, not probability-weighted outcome.
- “Rolling avoids a loss.” It realizes or carries the old result and creates a new spread with new risk.
