Call Option

What is a Call Option?

A call option is a contract giving the holder the right (but not the obligation) to buy an underlying asset at a fixed price (the strike) before a specified date (expiration). You pay a premium upfront to own that right. Call buyers profit when the underlying rises above the strike plus premium. For example, if you buy a $100 call paying $2 premium, you profit when the stock rises above $102.

Calls are leveraged: you control 100 shares (typically one contract) with a smaller upfront cost than buying the stock outright. If the stock rises $5, your $2 call premium might become $5, doubling your money. But if the stock falls or stays flat, you lose the premium paid. You have no obligation to exercise—if the stock falls below the strike, you let the option expire worthless and lose only the premium.

Call Buyers vs. Call Sellers

Call buyers benefit from rising prices and increasing volatility. They're long directional exposure with capped risk (the premium paid). Call sellers (writers) collect premium and profit if the stock stays flat or falls. Selling calls generates immediate income but creates unlimited loss potential if the stock rises sharply. Covered calls (owning stock and selling calls against it) are a lower-risk seller strategy.
