Key Terms and Definitions Associated with Stock Options:
1. Stock Option: A stock option is a
financial instrument that gives the holder the right, but not the obligation, to buy or sell a specific number of shares of a company's stock at a predetermined price (known as the strike price) within a specified period of time.
2. Call Option: A call option is a type of stock option that gives the holder the right to buy shares of a company's stock at the strike price before the expiration date. Call options are typically used when an
investor expects the price of the underlying stock to rise.
3. Put Option: A put option is a type of stock option that gives the holder the right to sell shares of a company's stock at the strike price before the expiration date. Put options are generally used when an investor anticipates the price of the underlying stock to decline.
4. Strike Price: The strike price, also known as the exercise price, is the predetermined price at which the holder of a stock option can buy or sell the underlying stock. It is agreed upon at the time the option contract is established.
5. Expiration Date: The expiration date is the last day on which the holder of a stock option can exercise their right to buy or sell the underlying stock at the strike price. After this date, the option becomes worthless.
6. In-the-Money: An option is considered in-the-money if it has
intrinsic value. For call options, this means the current
market price of the underlying stock is higher than the strike price. For put options, it means the current market price is lower than the strike price.
7. Out-of-the-Money: An option is considered out-of-the-money if it has no intrinsic value. For call options, this means the current market price of the underlying stock is lower than the strike price. For put options, it means the current market price is higher than the strike price.
8. Time Value: The time value of an option is the additional value attributed to the option beyond its intrinsic value. It represents the potential for the option to gain value before expiration due to factors such as time remaining until expiration,
volatility, and interest rates.
9. Vesting Period: In the context of employee stock options, the vesting period refers to the length of time an employee must work for a company before they can exercise their options. It is often used as an incentive to retain employees and align their interests with the company's performance.
10. Exercise: Exercising an option refers to the act of using the right granted by the option contract to buy or sell the underlying stock at the strike price. This is typically done when the option is in-the-money and the holder wishes to realize a profit or hedge against potential losses.
11. Premium: The premium is the price paid by the buyer of an option to the seller (writer) in exchange for the right to buy or sell the underlying stock. It represents the market value of the option and is influenced by factors such as the stock price, strike price, time remaining until expiration, and market volatility.
12. Option Chain: An option chain is a listing of all available options for a particular stock, organized by strike price and expiration date. It provides investors with a comprehensive view of the available options and their corresponding prices.
13. Implied Volatility: Implied volatility is a measure of market expectations for future price fluctuations of the underlying stock. It is derived from the prices of options and reflects the market's perception of potential risks and uncertainties.
14.
Stock Split: A stock split is a corporate action in which a company increases the number of its outstanding shares by dividing existing shares into multiple shares. This can affect stock options by adjusting the strike price and number of shares covered by each option contract.
15.
Dilution: Dilution refers to the reduction in existing shareholders' ownership percentage of a company due to the issuance of additional shares. It can impact stock options by potentially reducing their value and increasing the number of shares required to exercise the options.
Understanding these key terms and definitions associated with stock options is crucial for investors and individuals involved in the financial markets. It enables them to navigate the complexities of options trading, make informed investment decisions, and effectively manage their risk exposure.
