What Is a Stock Option?


A stock option is a contractual right to buy or sell a specific quantity of an underlying stock or asset, at a predetermined price, over a specific period of time. This type of financial instrument is offered by companies to employees, clients, and shareholders as a form of incentive or reward.

Types of Stock Options

  • Non-qualified Stock Options (NQOs)
  • Incentive Stock Options (ISOs)
  • Employee Stock Purchase Plans (ESPPs)

How They Work

A stock option offers an investor the right to buy or sell a particular stock at a predetermined price, on or before a specific date. For the buyer, an option offers the chance to gain from price movements with limited financial risk. For the seller, the cost of the option premium can be an attractive source of income.

The Buyer

The buyer purchases the right to buy or sell shares of the underlying asset at the predetermined price, called the strike price. They have the right, but not the obligation, to exercise their option which can then be used as leverage in various strategies. The buyer pays the seller an upfront cost, called the option premium. This premium goes directly to the seller and is the only compensation they receive, regardless of what happens to the price of the underlying asset.

The Seller

The seller receives the option premium up front and, in exchange, is obligated to either buy or sell the underlying asset at the strike price should the buyer exercise the option. If the seller does not complete the transaction when the option is exercised, they forfeit the option premium. The seller also incurs potential losses if the price of the underlying asset moves significantly in favor of the buyer.

Benefits of Stock Options

Being an owner of a company doesn’t always require you to buy the company’s physical assets and can actually be attained by purchasing stock options. Stock options, however, come with their own advantages and benefits for those who use them.

Stock options are a type of derivative security, meaning they derive their value from the underlying asset, which in this case is the stock of a company. A stock option gives its holder the right, but not the obligation, to purchase or sell a certain quantity of the underlying security at a fixed price over a set period of time.

Potentially Generate Profit

The potential to generate an extraordinary return on investment with stock options is one of the main reasons people choose to use them. If combined with proper knowledge and careful analysis it can also help you decrease your losses. Stock options can be extremely valuable because their price is typically a fraction of the underlying asset’s market price.

For instance, let’s say the market price of the underlying asset is costing $50 a share and you purchase a stock option at a much cheaper premium of $15. If the stock goes up to $70 you still have a profit because the value of the stock option will go up as well, to a certain extent, as the underlying asset’s price goes up.

Flexibility for Investors

Another big advantage of stock options is that it gives investors flexibility. You’re not required to buy or sell a certain amount of shares, you can essentially choose exactly which stocks you want to purchase or how many you want to purchase.

In addition, investors can choose the time frames that stock options trade for, depending on their investing strategies. During this time frame, you can take advantage of volatility by protecting your portfolio from price drops or even by speculating on price changes.

Stock options give investors a unique way to secure the future of their investments but they also make the stock market more accessible and flexible to a variety of different investors. Due to their low-cost nature, they represent an attractive option for those looking to get involved in the stock market.

Tax Implications of Stock Options

Stock options offer an attractive way to invest in an asset with a potential to obtain gains. However, they come with different tax implications that investors should be aware of in advance.

Deductions and Exemptions

When a stock option holder receives compensation from their stock options, employers can deduct the income from their taxes. As long as the employer uses the option for a compensatory purpose, any profits made from it may also be exempt from tax under the Section 1202 exemption of the Internal Revenue Code.

Under this category, investors can exclude up to $10 million of capital gains from the profits of their qualifying small business stocks over a five-year period. This exemption is only applicable to the original investor and cannot be passed on to successors or heirs.

Impacts on Trading for Investors

Stock options are viewed as investments by the government, which means that any income derived from holding them is subject to taxes on trading. The subject of taxation depends on the type of option that is being held by the investor.

For example, for a call option, the holder is liable for taxes on any profits earned from the option's exercise. On the other hand, for a put option, the holder pays taxes on any gains from selling the option. Additionally, participants in certain transactions related to stock options such as a wash sale can have tax implications.

It is important to note that different countries have different tax laws and regulations related to stock options. Investors should seek out professional guidance and advice to ensure full compliance with all applicable laws and regulations.

Pros and Cons of Stock Options

Purchasing stock options can be a great way to invest in a company without having to bear the risk associated with buying actual stocks. It is also a form of trading that allows for greater flexibility and more control over investments. There are both benefits and drawbacks, however, and it is important to consider both before investing.

Low Risk Investment

Using stock options is an investment strategy with a relatively lower risk. When a trader purchases a call option, they are able to buy the stock at a predetermined price, regardless of what the market value of the stock is later. This means that no matter how much the stock goes up or down in price, the trader will still benefit from the purchase.

Lack of Control

One disadvantage of stock options is the lack of control. Because the trader cannot influence the market or the company to affect the price of the stock, they must rely solely on the decisions of the company and the market to try and make a profit from their investment. This can often be difficult and risky and can limit the potential for profit.

Overall, stock options offer the potential for low risk investment and great flexibility, but it is important to understand that there are certain drawbacks that come with this type of trading. There is no one-size-fits-all approach when it comes to investing, and so it is essential that traders weigh the pros and cons of any type of investment before committing to it.

Exercising and Expiring Stock Options

Stock options give you the right to purchase or sell a certain number of shares at a specified price. Stock options can be an attractive addition to an investor’s portfolio, as they give investors the ability to potentially benefit from upward movements in the stock price. However, in order to realize these benefits, investors need to understand the process of exercising and expiring stock options.

Choosing When to Exercise

When the stock price reaches a certain level, investors have the option to exercise the stock option and buy or sell the underlying shares of stock. There is no time limit on when options can be exercised. Some investors may choose to exercise the option and buy shares when the stock price is lower than the exercise price. Conversely, some investors may wait until the stock price reaches the exercise price or higher before exercising the option. The decision of when to exercise the option depends on various factors such as the investor’s risk tolerance, tax situation, and the expected future performance of the stock.

What Happens When Options Expire?

When an option expires, the option holder no longer has the right to exercise the option. Once the option has expired, the buyer is no longer obligated to purchase or sell shares at the specified price. The rights associated with the option are terminated and the option no longer has any value.

Exercising and understanding when options expire is an essential part of stock option investing. Before exercising a stock option, investors should carefully research and assess their options in order to determine the best course of action.


To sum up, stock options provide employees with the opportunity to use investments in order to share in the success of the company. Stock options are limited in that they are often tied to restrictions on the length of time you must remain with the company before you are able to exercise them. However, if you stay with the company for a satisfactory length of time, stock options can provide an effective way to invest in your company’s success.

In the long-term, stock options can be a great way to supplement your wage with the profits of the company. Stock options offer employees the chance to benefit from the success of the company and can be a great way to increase your investment returns. With stock options, you can invest without having to use a large amount of your own capital while also taking advantage of the potential tax savings.

In conclusion, stock options can be a smart and rewarding way to invest in the success of the company for the long-term. Stock options can provide an effective way to increase your wealth, supplement your wages and enjoy potential tax savings. Before you consider investing in stock options, make sure you understand all of the restrictions and associated costs.
