society Maturity 11-13 Next article →

An option is a special kind of financial contract.

It gives the owner a specific right. This right lets them buy or sell an asset at a set price. This set price is called the strike price. The owner does not have to use this right if they do not want to. They can simply let the contract end. To get this right, the person usually pays a fee called a premium. This premium is the cost of having the choice.

If the person does not use the option, they lose the premium they paid.

There are two main types of options used in finance. A call option gives the holder the right to buy an asset. People often use call options when they think the market price will go up. A put option gives the holder the right to sell an asset.

These are useful if someone thinks the market price will go down. The contract also has an expiration date. This is the last day the person can use their right. Once this date passes, the option is over. The owner cannot use it to buy or sell anything anymore.

People have used ideas similar to options since ancient times.

A Greek philosopher named Thales of Miletus is a famous early example. He heard that a large olive harvest was coming. He paid for the right to use olive presses in the spring. When the harvest was huge, he used his right. He then rented the presses to others for a much higher price. Later, in 1688, a book described trading "opsies" in Amsterdam. In the 1690s, these tools became well-known in London during the reign of William and Mary.

Today, options are traded in two main ways. Some are traded on public exchanges. These are called exchange-traded options. They use standardized forms so everyone knows the rules. These trades are often handled by a clearing house to keep things safe.

Other options are traded "over-the-counter." This means two private parties make a custom deal. These deals can be tailored to fit a specific need. They do not happen on a public market. This allows people to create very specific rules for their contracts.

Options are useful in many parts of our world.
