Call Option

A Call Option is a financial contract that gives the buyer the right, but not the obligation, to purchase a specific quantity of an underlying asset at a predetermined price (known as the strike price) within a specified time period.

Understanding Call Options

Key Components of a Call Option

• Underlying Asset: The financial instrument (such as stocks, commodities, or indices) that the option is based on.
• Strike Price: The price at which the underlying asset can be bought if the option is exercised.
• Expiration Date: The date by which the option must be exercised or it becomes worthless.
• Premium: The price paid by the buyer to the seller for the call option.

How Call Options Work

When an investor buys a call option, they are speculating that the price of the underlying asset will increase. If the market price exceeds the strike price before expiration, the investor can exercise the option to buy shares at the lower strike price. If the price does not exceed the strike price, the investor may choose not to exercise the option, resulting in a loss limited to the premium paid.

Example of a Call Option

Let’s consider an investor, Alice, who believes that the stock of Company XYZ, currently priced at $50, will rise in value.

Assumptions

• Current price of Company XYZ: $50
• Strike price of the call option: $55
• Premium paid for the call option: $2
• Expiration date: 1 month from today

Scenario 1: Stock Price Increases

If the stock price rises to $65 at expiration, Alice can exercise her option:
– She buys 1 share at the strike price of $55.
– Total cost = Strike price + Premium paid = $55 + $2 = $57.
– Market value of the share = $65.
– Profit = Market value – Total cost = $65 – $57 = $8.

Scenario 2: Stock Price Does Not Increase

If the stock price remains at $50 (or below $55) at expiration, Alice will not exercise her option:
– She loses the premium paid = $2.

Calculation Details

To evaluate the profitability of a call option, the following calculations are useful:

1. Breakeven Point: The price at which the investor neither makes a profit nor loses money.
– Breakeven = Strike price + Premium = $55 + $2 = $57.

2. Profit or Loss Calculation:
– Profit = (Market price – Total cost) * Number of options exercised.
– Loss = Premium paid if option is not exercised.

By understanding Call Options, investors can leverage their expectations about future price movements, but it is essential to be aware of the risks and potential losses associated with these financial instruments.
