Understanding Call Options
What Is a Call Option?
A call option is a financial contract that gives the buyer the right, but not the obligation, to purchase a stock at a specific price (called the strike price) within a certain time frame. Traders use call options to speculate on the price of a stock rising or to hedge against other positions.
What Is a Long Call?
A long call refers to the act of buying a call option. This strategy is used when a trader believes the price of the underlying stock will go up. The buyer pays a premium for the option and profits if the stock price rises significantly above the strike price before expiration.
Key characteristics of a long call:
- Limited risk: the maximum loss is the premium paid
- Unlimited upside potential if the stock price rises
- Used in bullish market outlooks
What Is a Short Call?
A short call, also known as a naked call, involves selling a call option without owning the underlying stock. This strategy is used when a trader expects the stock to stay flat or decline. The seller collects the premium up front, but is exposed to unlimited risk if the stock price surges.
Important: Because the seller does not own the underlying shares, losses can be unlimited if the stock rises significantly. Naked calls are considered high-risk and are typically used by experienced traders.
Key characteristics of a short (naked) call:
- Maximum profit: the premium received
- Unlimited risk if the stock price rises
- Best used in neutral or bearish markets
What Is a Covered Call Option?
A covered call is an options strategy where the trader sells a call option while simultaneously owning the equivalent amount of the underlying stock. This is considered a conservative income-generating strategy, often used when the trader expects minimal price movement in the stock.
Because the stock is already owned, the risk of a large loss is reduced. However, the upside potential is limited to the strike price plus the premium received.
Key characteristics of a covered call:
- Generates income through the call premium
- Reduces downside slightly but caps upside gains
- Best for neutral to mildly bullish outlooks
