Derivative

What Is a Derivative?

A derivative is a contract between two parties that sets terms for a future transaction or payment. Its value is not fixed on its own. Instead, it moves up and down with the price or level of something else, called the underlying. That underlying can be a stock, a bond, a commodity such as oil or wheat, a currency, an interest rate, or a market index such as the S&P 500.

Derivatives are used for two broad purposes. Some participants, called hedgers, use them to reduce the risk of price changes in something they own or expect to buy or sell. Others, called speculators, use them to take a position on where prices are headed. Many investors use them for both reasons at different times.

Common Types

The most widely used types include:

• Futures: a standardized agreement to buy or sell an asset at a set price on a future date, traded on exchanges.
• Options: a contract that gives the buyer the right, but not the obligation, to buy or sell an asset at a set price before a set date. The buyer pays a premium for this right.
• Swaps: an agreement to exchange streams of payments, such as fixed interest payments for floating ones. Most swaps are traded privately between institutions.
• Forwards: similar to futures but privately negotiated and not usually traded on an exchange.

Why It Matters to Investors

Derivatives can offer leverage, meaning a small amount of money controls a much larger position. This can magnify gains, but it can also magnify losses, sometimes beyond the original amount invested. Derivatives also carry counterparty risk when they are traded privately, since the other party may fail to meet its obligations. Because a derivative's price depends on its underlying, its value can change quickly, and some contracts lose their value entirely if they expire unused.

Understanding what a derivative is linked to, how its terms work, and how much risk it carries is an important first step for any investor who encounters these instruments, whether directly or through funds that use them.
