A bear call spread is an options strategy in which a trader sells a call option at one strike price and buys another call option on the same asset, with the same expiry, at a higher strike price. Because the option sold is worth more than the option bought, the trader receives a net premium, or credit, at the start. The position profits if the price of the underlying asset stays at or below the lower strike until expiry, and its potential loss is capped by the higher-strike call.
The strategy is also called a short call spread or a bear call credit spread. It belongs to the family of vertical spreads, built from two options contracts that differ only in strike. It suits traders who are moderately bearish or neutral, and it is offered on share, index and, on some venues, crypto options markets. Its mirror image for a bullish view is the bull put spread.
Bear call spread in plain terms
Imagine you sell someone the right to buy your bicycle for $300 at any time in the next month, and they pay you $20 for that right. You think bicycle prices will not rise that much. To protect yourself in case they do, you pay a friend $5 for the right to buy an identical bicycle from them for $350. You have pocketed $15 overall.
If bicycle prices stay below $300, nobody uses their rights and you keep the $15. If prices jump far above $350, you must sell at $300 but can buy at $350, so your worst loss is limited to the $50 gap minus the $15 you collected. That is a bear call spread: a modest, capped bet that a price will not climb.
How the strategy works
The trader opens two legs at once:
- Short call at the lower strike. This is the main source of income, because the trader collects its premium and accepts the obligation to sell the asset at that strike if the option is exercised.
- Long call at the higher strike. This costs less and acts as insurance, capping the loss if the price rises sharply.
Both options share the same expiry date and underlying asset. Brokers usually treat the pair as a single defined-risk position, so the margin required is roughly the gap between the strikes minus the credit received, much lower than for an uncovered short call.
Formula and example
The maximum profit is the net credit received:
The maximum loss is the strike width minus the credit:
The break-even price at expiry is:
- and are the lower and higher strike prices.
- is the premium received for the call sold at the lower strike.
- is the premium paid for the call bought at the higher strike.
Suppose a share trades at $95. A trader sells a call with a $100 strike for $4 and buys a call with a $105 strike for $1.50, both expiring in a month. The net credit is , or $250 for a standard 100-share contract. If the share closes at or below $100, both options expire worthless and the trader keeps $250. The break-even is . If the share closes at $105 or above, the loss is per share, or $250 per contract, the maximum possible.
When traders use it
A bear call spread fits a view that a price will fall slightly, stay flat or rise only a little. It benefits from time decay, since both options lose value as expiry approaches, and from falling volatility, because lower implied volatility reduces option prices. Traders often place the short strike above a level they see as resistance. Many traders also use it for hedging a long holding against a modest fall. Compared with short selling the asset, the spread has a known maximum loss and does not require borrowing shares, but its profit is capped at the credit received. Compared with buying a put, it earns money in a sideways market rather than needing a sharp fall.
Risks and practical points
The main risks are:
- Losses larger than gains. The maximum loss is often bigger than the maximum profit, so a few losing trades can wipe out many winners.
- Early assignment. With American-style options, the short call can be exercised before expiry, especially just before an ex-dividend date, leaving the trader short the shares.
- Gaps. A sudden jump in price, such as after earnings news, can move the position straight to maximum loss.
- Costs. Two legs mean two sets of commissions and the bid-ask spread on each, which matters for narrow spreads.
In crypto, options on bitcoin and ether trade on specialised exchanges and some regulated venues such as CME, often in European style, which removes early-assignment risk. Crypto option prices reflect very high volatility, so premiums are larger, but so is the chance of large moves that reach the maximum loss. Like all derivatives, and as part of any sound approach to risk management, the strategy suits traders who understand option pricing, and its value can be modelled with tools such as the Black-Scholes model.
