What is Short Call?
A short call is an options strategy where you sell a call option, obligating yourself to sell the underlying asset at the strike price if exercised. This approach is typically used when you expect the asset price to remain neutral or decline, allowing you to keep the premium as profit if the option expires worthless.
Also known as a naked call, it exposes you to potentially unlimited losses if the asset price rises significantly above the strike price.
Key Characteristics
Understanding the main features of a short call helps you manage its risks and rewards effectively:
- Premium Income: You receive an upfront premium for selling the call, which represents your maximum profit.
- Obligation to Sell: If exercised, you must sell the underlying asset at the strike price, regardless of the market price.
- Unlimited Loss Potential: Losses can grow indefinitely if the underlying asset rallies sharply, as seen in a strong rally.
- Time Decay Benefit: The option seller profits from theta decay as the option's value erodes approaching expiration.
- Margin Requirements: Positions often require margin, reflecting the risk of assignment and price movement.
How It Works
To execute a short call, you sell a call option on an underlying asset like Microsoft without owning the shares. You collect the option premium upfront, betting the stock price stays below the strike price until expiration.
If the asset stays below the strike, the option expires worthless, and you keep the premium as profit. However, if the price rises above the strike, you face potential assignment and must deliver the shares at the agreed strike price, possibly incurring substantial losses.
Examples and Use Cases
Short calls are useful in various market scenarios where you anticipate limited upside movement or a decline:
- Technology Sector: Selling calls on Microsoft during neutral market phases to generate income from premium decay.
- Index ETFs: Using short calls on SPY to collect premiums in sideways markets.
- Airlines: Traders might short calls on stocks like Delta when expecting resistance or no significant price increase.
Important Considerations
While short calls can generate steady income, you must carefully manage the risk of early exercise and unlimited losses. It’s vital to monitor positions closely and use risk controls such as stop-loss orders or position sizing.

Final Words
A short call offers limited profit potential with significant risk if the underlying asset rises sharply. Carefully assess your market outlook and risk tolerance before selling calls, and consider setting alerts to monitor price movements closely.
Frequently Asked Questions
A short call is a bearish to neutral options strategy where you sell a call option, receiving a premium upfront. You are obligated to sell the underlying asset at the strike price if the option is exercised.
You profit from a short call if the underlying asset stays at or below the strike price by expiration, causing the option to expire worthless. In this case, you keep the entire premium received as your maximum profit.
The main risk is unlimited loss because if the asset price rises significantly above the strike price, you must sell at the strike price and buy at the higher market price. This can lead to potentially large losses.
A short call works best when you expect the underlying asset to remain stable, move sideways, or decline slightly. If you expect a strong bearish move, other strategies like long puts may be more suitable.
Choosing out-of-the-money strikes offers lower premiums but higher chances the option expires worthless. Shorter expirations increase time decay, which benefits sellers by eroding option value faster.
The breakeven price is the strike price plus the premium received. For example, if you sell a $100 strike call for $3, your breakeven is $103.
Yes, assignment risk exists anytime the option is in-the-money. This means you might be required to sell the underlying shares at the strike price before expiration.
