How Do Options Contracts Work?

There are four components to every options contract:

The underlying asset
The strike price
The expiration date
The cost (also known as the premium)

An options contract is simply an agreement between a buyer and a seller.

Buying an option gives you the right to buy or sell stock.

Selling an option obligates you to buy or sell stock.

You can sell an option contract you don’t already own. This is similar to short selling stock (though you don't have to be bearish on the underlying security, as you'll learn below).

If you buy an option, you can sell it before the contract expires.

If you sell an option, you can also exit your position at any time. However, you could be assigned shares of stock, which is your risk as the seller. (More on assignment later).

The Handbook has a comprehensive introduction to options basics.

Let’s take a closer look at an options contract.

Underlying Asset

Every option contract is linked to an underlying asset.

Options are a derivative financial instrument. Derivatives get their value from something else. Options derive their value from the contract’s underlying asset.

For example, an Amazon option's value is based on the the price movement of AMZN stock.

One option contract is equivalent to 100 shares of stock. This is known as the contract multiplier.

Strike Price

Every option has a strike price.

An option’s strike price is the price you can buy or sell the underlying security.

For example, a call option with a $100 strike gives the buyer the right (but no obligation) to buy 100 shares (per contract) of the underlying security for $100 per share. The option seller is required to sell the 100 shares at $100. (More on call options later).

Expiration Date

All options have an expiration date. The expiration date is the final day the contract can be traded or exercised.

You do not have to hold an option until expiration. You can exit an option position before the expiration date to lock in a profit or minimize a loss.

Option Premium

Several factors influence an option’s price. Every option has extrinsic and intrinsic value.

What is extrinsic and intrinsic value?

Extrinsic value comes from factors such as time and volatility. The more time until expiration or the higher the implied volatility, the more expensive the option.

Intrinsic value (also known as an option’s moneyness) is determined by the underlying’s price relative to the option’s strike price.

A call option’s intrinsic value is the amount the underlying’s current price is above the option’s strike price. A put option’s intrinsic value is the amount the underlying’s current price is below the option’s strike price.

For example, if a stock is trading at $105 per share, a call option with a $100 strike price would be in-the-money and have an intrinsic value of $5.

If the underlying security’s price is below the call option’s strike price, the call option is out-of-the-money, and the intrinsic value is $0.

In-the-money options are more expensive than out-of-the-money options because they have intrinsic value.

Exercise & Assignment

Exercise and assignment are two sides of the same transaction. An option buyer has the right to exercise an options contract. An options seller is obligated to accept assignment from an exercised contract.

Option holders (the buyer) can exercise an option any time before expiration. However, a buyer would only exercise their option if it was in their best interest.

For example, if you own a call option with a $100 strike price and the stock is currently trading at $95, it does not make sense to exercise the option.

If the stock price is $105 and near expiration, you could exercise the option and own shares at $100.

Option writers (the seller) cannot refuse assignment. Assignment is random and can happen anytime before expiration, though it typically happens late in the expiration cycle.

The Handbook has a deeper dive into the exercise and assignment process.

Call and Put Options

All options are divided into two types: calls and puts. A call option’s value increases if the stock’s price goes up. A put option’s value increases if the stock’s price goes down.

Call Options

Buying a call option gives you the right to buy shares of a stock at the option’s strike price.

Selling a call option obligates you to sell shares of a stock at the option’s strike price.

Buying a call option means you're bullish on the stock because a call option’s value increases when a stock’s price increases. Selling a call option is bearish because you benefit from the stock's price declining.

Put Options

Buying a put option gives you the right to sell shares of a stock at the option’s strike price.

Selling a put option obligates you to buy shares of a stock at the option’s strike price.

Buying a put option means you're bearish on the stock because a put option’s value increases when a stock’s price decreases. Selling a put option is bullish because you capitalize on the stock's price rising.

Using Options

Many investors buy options because they have defined risk and are a cost-effective alternative to buying stock.

For example, buying a call option is a less expensive alternative to owning 100 shares of stock, with the added bonus of knowing your max loss when you enter the trade.

Combining options with a stock position is a popular first step for many new options traders. Covered calls enable you to potentially generate income while owning shares of stock.
