An option is a financial contract that gives the buyer the right to buy or sell an underlying asset at a set price before a specific date.

Options belong to a class of assets called derivatives. This means they do not have intrinsic value on their own. Instead, their value comes from another asset, such as a company stock or a commodity.


Key Parts of an Option

Every option contract has basic rules and terms:

  • Underlying Asset: The stock, bond, or index the option is tied to.
  • Strike Price: The agreed-upon price to buy or sell the asset.
  • Expiration Date: The final day the contract is valid.
  • Premium: The upfront price paid to buy the option contract.

The Two Main Types of Options

Investors use two main types of option contracts depending on their market outlook:

  • Call Option: Gives the buyer the right to buy a stock at the strike price. Investors buy calls when they think the stock price will go up.
  • Put Option: Gives the buyer the right to sell a stock at the strike price. Investors buy puts when they think the stock price will go down.

How Options Work as an Asset

When you buy an option, you own a legal contract. You can trade this contract on public markets before it expires.

  • The Buyer’s Risk: The most money a buyer can lose is the premium paid for the contract.
  • The Buyer’s Reward: Profits can be high if the stock price moves in the right direction.
  • The Seller’s Risk: The person who sells the option takes on the obligation to fulfill the trade, which can lead to large losses if the market moves against them.
