op·tion (ŏp′shən) n. 1. The act of choosing; choice: Her option was to quit school and start her own business. 2.

American options can be exercised any time before the expiration date of the option, while European options can only be exercised on the expiration date exercise date. Exercising means utilizing the right to buy or the sell the underlying security. Option on stocks typically represent shares. In terms of speculation, option buyers and writers have conflicting views regarding the outlook on the performance of an underlying security.

An option writer who sells a call option believes that the underlying stock's price will drop or stay the same relative to the option's strike price during the life of the option, as that is how they will reap maximum profit. The writer's maximum profit is the premium received when selling the option. If the buyer is right, and the stock rises above the strike price, the buyer will be able to acquire the stock for a lower price strike price and then sell it for a profit at the current market price.

Risk to the call buyer is limited to the premium paid for the option, no matter how much the underlying stock moves. The profit at expiration, if applicable, is: This will give the total profit or loss to the trader in dollars. The risk to the call writer is much greater. Their maximum profit is the premium received, but they face infinite risk because the stock price could continue to rise against them. To offset this risk, many option writers use covered calls.

The opposite is true for a put option writer. For example, a put option buyer is bearish on the underlying stock and believes its market price will fall below the specified strike price on or before a specified date. If the underlying stock's price closes above the specified strike price on the expiration date, the put option writer's maximum profit is achieved. They get to keep the entire premium received.

Conversely, a put option holder benefits from a fall in the underlying stock's price below the strike price. If the underlying stock's price falls below the strike price, the put option writer is obligated to purchase shares of the underlying stock at the strike price.

This is then multiplied by if each contract is shares and the number of contracts bought. The risk to the option writer if the stock price falls is that they have to buy the stock at the strike price.
