Bear Call Spread options strategy

What is a bear call spread?

A bear call spread is a credit spread built by selling a call at a lower strike and buying a call at a higher strike with the same expiration. The lower-strike call brings in more premium than the higher-strike call costs, so the trader receives a net credit up front. That credit is the most the trade can earn. The long call caps the loss if the underlying rallies, turning what would be an uncovered short call into a defined-risk position.

It is also called a short call vertical or call credit spread. The strategy is used for a bearish to neutral view: it profits if the underlying falls, stays flat, or rises only slightly.

When to use it and the market view

A bear call spread suits a trader who expects the underlying to stay below a certain level rather than one who expects a sharp drop. If a stock trades near $198 and you believe $200 will act as resistance through expiration, selling the 200 call and buying the 210 call lets you collect premium while defining the worst-case outcome. Unlike a debit spread, the trade does not need the price to move; time passing is enough if the underlying stays below the short strike.

Because the position is net short options, it is typically considered when implied volatility is relatively high, which increases the credit collected. It is also a common, more controlled alternative to a naked short call, since margin requirements are based on the spread width rather than an open-ended obligation.

Payoff, formulas, and a 200 strike example

Let K1 be the lower (short) strike, K2 the higher (long) strike, S the expiration price, and C the net credit.

Profit = C − max(S − K1, 0) + max(S − K2, 0)

Breakeven = K1 + C · Maximum profit = C · Maximum loss = (K2 − K1) − C

Suppose you sell the 200 call for $8 and buy the 210 call for $4, a net credit of $4 per share ($400 per contract). At expiration:

• S = 195: both calls expire worthless. Profit = +$4, the maximum.
• S = 202: the short call is worth 2. Profit = 4 − 2 = +$2 per share.
• S = 204: profit = 4 − 4 = $0, the breakeven.
• S = 207: profit = 4 − 7 = −$3 per share ($300 per contract).
• S = 220: profit = 4 − 20 + 10 = −$6 per share ($600 per contract), the maximum loss.

The trade collects $400 while risking $600. Credit spreads usually have a higher probability of a small profit and a lower probability of a larger loss, so they need careful sizing.

Maximum profit, loss, and breakeven

Measure	Formula	200/210 spread, $4 credit
Maximum profit	Net credit	$4 per share ($400 per contract) at or below 200
Maximum loss	(K2 − K1) − credit	$6 per share ($600 per contract) at or above 210
Breakeven at expiration	K1 + credit	$204

Greeks and implied volatility impact

The spread has negative delta: gains when the underlying falls and losses when it rises. Theta is usually positive when the underlying is below the short strike, since the short call's time value decays faster than the long call's. Gamma is negative near the short strike, so a sharp rally can move the position against you quickly as expiration approaches.

Vega is generally negative. A drop in implied volatility tends to reduce the spread's value and helps the seller, while a spike in IV can create an unrealized loss even if the underlying has not moved. Because the long call offsets part of the volatility exposure, the effect is smaller than for a naked short call.

Risks to manage

The main risk is a rally through the short strike. If the short call goes in the money, early assignment is possible, especially before an ex-dividend date, leaving a short stock position until you exercise the long call or close the trade. Because the loss is larger than the credit, a few losing trades can offset many small winners. Traders often set an exit rule, such as closing when the spread reaches a multiple of the credit received, and avoid holding into expiration when the price is near the short strike.
