Stock options 101: Learn the basics
Stock options are a popular financial instrument that gives investors the right, but not the obligation, to buy or sell a stock at a predetermined price. Whether you're a seasoned investor or new to trading, understanding the basics of stock options can open up new opportunities for portfolio diversification. This article will guide you through the fundamentals, including how stock options work, their different types, and how to trade them effectively.
What is a stock option
A stock option is a contract that grants the holder the right to buy or sell a stock at a specific price within a certain timeframe. Unlike owning the stock itself, a stock option provides flexibility in trading, allowing you to potentially take advantage of price fluctuations without committing to buying or selling shares upfront. These contracts are often used for hedging, speculation, or employee compensation and are traded on regulated exchanges.
How stock options work
Stock options work by giving investors some 'control' over a specified number of shares without requiring full ownership. The price agreed upon is known as the strike price, and the period during which the option can be exercised is the expiration date. Options can be bought and sold much like stocks but involve more complex decision-making due to factors like time value, volatility, and market conditions, which can affect an option’s premium.
Types of stock options
ISOs and NSOs
There are two main types of employee stock options: Incentive Stock Options (ISOs) and Non-Qualified Stock Options (NSOs). ISOs offer favorable tax treatment but are subject to more restrictions, typically available only to employees. NSOs are more flexible and can be granted to employees, directors, or outside consultants, but they are taxed at ordinary income rates when exercised.
Call and put options
Call options give the holder the right to buy a stock, while put options give the right to sell. Calls are typically used when an investor expects a stock's price to rise, while puts are used when an investor anticipates a price decline. Both types are essential components of options strategies designed to manage risk, generate income, or profit from market movements by leveraging the flexibility of options.
Stock options terms
American options vs. European options
American options can be exercised at any point before or on the expiration date, giving traders greater flexibility. European options, however, can only be exercised on the expiration date itself. The difference in exercise rules impacts the strategies investors use and the premiums they are willing to pay for these options.
Premium
The premium is the price paid for purchasing an option. This cost is influenced by factors like the stock’s current price, the strike price, time until expiration, and market volatility. The premium represents the risk and potential reward of the option contract and is crucial in determining whether a trade is worth making.
Strike price
The strike price is the predetermined price at which the stock can be bought (call option) or sold (put option) if the option is exercised. This price plays a key role in determining the potential profitability of the option, as it needs to be favorable relative to the market price for the option to be valuable.
Expiration date
The expiration date is the last day an option can be exercised. After this date, the option becomes worthless, and the holder loses the premium paid. Short-term and long-term options exist, with shorter-term options being more volatile but potentially more rewarding.
Options contract
An options contract typically represents 100 shares of the underlying stock. This leverage allows traders to control a large number of shares with a smaller investment, magnifying potential gains — or losses — depending on how the stock price moves.
Employee stock options
Employee stock options are a type of compensation where employees are granted the right to purchase company stock at a discounted price. These options often come with a vesting period, meaning employees must wait for a certain amount of time before they can exercise them. Offering stock options is a way for companies to align the interests of employees with the company’s performance.
How to trade stock options
Stock options are traded on major exchanges such as the Chicago Board Options Exchange (CBOE), NASDAQ PHLX, and the International Securities Exchange (ISE). Traders can buy or sell options on these platforms, depending on their market outlook and trading strategy, or on trading platforms such as moomoo.

How to buy stock options
To buy stock options, start by selecting a brokerage platform and choosing the stock and option type (call or put). For example, if you expect a stock to rise, you might buy a call option with a favorable strike price and expiration date. Once purchased, monitor the stock’s movement to decide whether to hold or sell the option.
How to sell stock options
Selling stock options involves offering the right to buy or sell a stock at a specific price to another investor. For instance, if you own a call option and the stock’s price rises, you can sell the option for a potential profit. Selling can be done before the expiration date, allowing you to realize potential gains based on market conditions.
How to calculate the value of stock options
Investors can use different tools and strategies to estimate an option's value and price, including options pricing models. These mathematical frameworks are used to estimate the theoretical value of options contracts, providing investors with a way to calculate the theoretical fair price of an option based on various factors. This includes current underlying asset prices, the option's strike price, time until expiration, interest rates, dividends, and market volatility. Understanding how these factors interact is key to making informed trading decisions.
Potential benefits and risks of stock options
Stock options offer several potential benefits, including leverage, flexibility, and the ability to hedge against price movements. However, they also come with potential risks, such as the potential to lose the entire premium paid if the stock price doesn’t move as expected. Managing risk and understanding the underlying stock’s behavior are critical when trading options.
