Key Terms

Stock Option (right to buy), exercise price, expiration date

3 terms

Stock Option (right to buy) financial

"Security described as Stock Option (right to buy) with common stock underlying"

exercise price financial

"Options carry an exercise price for the underlying common stock"

The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.

expiration date financial

"The stock options are reported with a specific expiration date"

The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised. It matters to investors because it determines the timeframe during which they can take action or benefit from the contract, similar to how a coupon or a food item has a limited period of usefulness. Once the expiration date passes, the contract loses its value or ability to be used.
