Bear Call Spread

A bear call spread sells a call and purchases another call at a higher strike on the same underlying. Equal quantities, matching contract sizes, and a common expiration create a vertical credit spread with finite maximum profit and loss. The lower-strike call receives more premium than the higher-strike call costs, while the purchased right limits the expiration loss from an underlying rise.

The position has a neutral-to-bearish expiration profile: its full credit is earned at or below the short strike, and a rise through the strike interval progressively reduces that result. It differs from an uncovered short call because losses stop increasing beyond the protective call’s strike.

Construction and example

A hypothetical example uses SPY at $750 and calls with 45 days remaining. Selling one $775 call for $8.50 per share and purchasing one $800 call for $3.50 produces a $5 per-share net credit. Standard 100-share contracts make the opening receipt $500. The higher-strike purchase uses part of the premium received to establish protection against a further rise.

Expiration payoff

At $775 or below at expiration, both calls have zero payoff and the maximum profit is the $500 credit. Between $775 and $800, only the short call has intrinsic value. Each $1 increase in SPY adds $100 to the obligation and reduces the position’s result by the same amount.

At $780, the short call’s $5 per-share payoff exactly uses the opening credit, giving the expiration break-even. At $790, its $15 per-share payoff is $1,500 for the contract. Deducting that obligation from the $500 credit leaves a $10 per-share loss, or $1,000 for the spread.

At and above $800, the higher-strike call offsets further growth in the short call’s payoff. The right to purchase at $800 is paired with the obligation to sell at $775, leaving a fixed $25 per-share payoff difference. After the $5 credit, the maximum loss is $20 per share, or $2,000 for one spread.

The credit is therefore both the initial receipt and the maximum expiration profit, but the protective call and strike width establish the loss limit. Those roles should not be confused with the broker’s collateral or delivery requirements.

Value before expiration

Closing the spread buys back the $775 call and sells the $800 call. A $3 per-share net closing debit costs $300 and leaves a $200 profit from the $500 opening credit. A closing debit above $5 per share produces a loss.

With SPY below both strikes, the remaining time value generally diminishes toward expiration if other inputs are unchanged, reducing the amount required to close. A rise toward $775 usually increases the short call’s value more than the protective call’s value and raises the spread’s repurchase cost. If SPY remains above both strikes, the combined obligation instead converges toward the $25 expiration difference.

Time and implied volatility do not have one fixed effect throughout the price range. The calls’ sensitivities differ and evolve as the underlying moves. A common IV increase can affect the two premiums unequally, and changes in strike-specific volatility can further alter the closing price. The finite expiration loss does not imply that the position has a fixed pre-expiration market value.

Exercise, assignment, and execution

SPY calls permit early exercise. Assignment of the $775 call requires delivery of 100 shares at that strike. The $800 call remains a separate right to purchase shares, which can be used to cover delivery. Exercising it realizes the strike-width cost before the opening credit; closing the shares and remaining option through market transactions can provide another resolution and may recover time value.

A dividend can make early call exercise more attractive when the option is in the money and has little time value. At expiration between the strikes, the lower call may be assigned while the higher call expires unused. A resulting short share position then has no continuing protection from the expired call and remains exposed to a later rise. The account must also support interim delivery and financing requirements.

A complex closing order can preserve the one-to-one ratio for each filled package and impose a net price limit. It can nevertheless leave some spreads unfilled, and it does not make the two contracts a single object for exercise and assignment.

Payoff formulas

Let $K_L$ be the lower short-call strike, $K_H$ the higher purchased strike, $c$ the credit per share, and $S_T$ the final underlying price. The short call payoff is subtracted and the protective call payoff added. For $q$ complete spreads with multiplier $M$:

For a positive credit smaller than the strike width:

The break-even lies between the strikes, where only the short call has intrinsic value and that value equals the credit. Above both strikes, the width less the credit gives the fixed loss. Repeating the complete pair scales dollar results without changing the price boundaries or the protective ratio.
