Bear Call Spread at a glance

How a bear call spread works

The short call collects the premium, and the long call further out of the money turns the unlimited risk of a naked call into a defined one. You do not need the stock to fall; you only need it to stay below the short strike. Brokers typically require margin equal to the width between the strikes minus the credit, so the trade is open to accounts approved for spreads without the naked call level an uncovered short call demands.

At expiration, below the short strike both calls expire worthless and the full credit is yours. Between the strikes the short call gains intrinsic value against you, and profit falls one for one as the stock rises. Above the long strike both calls are in the money, their changes offset, and the loss is flat at its maximum: the width between the strikes minus the credit. The breakeven sits at the short strike plus the credit.

Time decay helps from the start, and so does falling implied volatility. Rallies hurt through negative delta and, as the stock nears the short strike, negative gamma. Unlike a put credit spread, a call spread often sees implied volatility ease when stocks rise, which can soften the mark to market pain of a slow rally. The real danger is a gap higher on earnings or deal news, which can push the spread to its maximum loss overnight with no chance to adjust.

Bear Call Spread example with real numbers

With the stock at $100, implied volatility at 30%, a 4.1% risk free rate and no dividend, you would sell 1 102.5 call (32 days) at $2.63, buy 1 107.5 call (32 days) at $1.17. That is a net credit of $146. At expiration a maximum profit of $146 and a maximum loss of $354, with a breakeven at $103.96. The lognormal chance of profit is 67%.

When to use a bear call spread

• You are neutral to bearish and expect the stock to stay below a resistance level through expiration.
• Implied volatility is elevated and you want to sell call premium with defined risk.
• You want a bearish trade that profits from time passing rather than requiring a decline.
• You want the exposure of a short call without naked call approval or unlimited risk.

Max profit, max loss and breakeven

Maximum profit

Net credit received times 100. You keep all of it if the stock closes at or below the short, lower strike at expiration.

Maximum loss

Higher strike minus lower strike minus net credit, times 100. This occurs if the stock closes at or above the long, higher strike at expiration, and any dividend owed after an early assignment comes on top.

Breakeven

Lower strike plus net credit per share. Above this price at expiration the spread loses money.

Bear Call Spread Greeks

• Delta: Delta is negative, so the spread gains as the stock falls or stays put. Its size peaks with the stock between the strikes.
• Gamma: Gamma is negative near the short strike, where losses accelerate on a rally, and fades above the long strike.
• Theta: Theta is positive while the stock is below the short strike and grows as expiration nears.
• Vega: Vega is negative at entry, so a drop in implied volatility helps and a rise hurts.

Early exercise and assignment risk

Bear call spreads carry real dividend risk. If the short call is in the money on the day before an ex dividend date and the dividend is larger than its remaining time value, call holders are likely to exercise. Assignment leaves you short 100 shares per contract, and if you are still short on the ex date you owe the dividend. That charge comes on top of the spread's loss, so the true worst case can exceed the theoretical maximum shown in the calculator. Check ex dividend dates before entering.

After an assignment, act promptly. Buy shares in the market to cover the short and then sell or keep the long call, or, if the stock is above the long strike, exercise the long call to cover at the higher strike, which locks in the defined maximum loss. Never ignore an assignment, because short stock has unlimited risk once your long call expires. Pin risk at expiration works the same way: a close near the short strike can leave you short stock unexpectedly, so close the spread before the final session.

The calculator's Early exercise risk tab flags short legs that are likely to be assigned. For a single option, use the early exercise calculator or read how early exercise and assignment work.

Pros and cons

How to manage a bear call spread

• Avoid holding an in the money short call over an ex dividend date.
• Take profits once most of the credit has decayed instead of holding through expiration week.
• Roll up and out for a net credit if the stock tests the short strike and your outlook still holds.
• Pair it with a bull put spread to build an iron condor if you expect a range rather than a decline.
