IndexFutures

Index futures are standardized contracts to buy or sell a cash equivalent of a stock market index at a specified future date. They allow participants to hedge or speculate on broad market moves without trading the underlying stocks. Commonly traded index futures include products based on major benchmarks such as the S&P 500, the Dow Jones Industrial Average, and the Nasdaq-100, as well as international indices on regional exchanges. The contracts are cash-settled, so no physical shares are delivered; settlement is based on the index level at expiry.

Trading takes place on regulated futures exchanges. Each contract has predefined specifications, including a contract multiplier, expiry months, and tick size. Traders post margin with the clearinghouse, consisting of an initial margin and maintenance margin. Prices are marked to market daily, and gains or losses are settled through variation margin. The clearinghouse guarantees performance, reducing counterparty risk.

Pricing reflects expectations for the index at expiration, adjusted for carry costs such as interest rates and expected dividends. In practice, futures can trade above or below the current index price (contango vs. backwardation), and arbitrage helps align futures with the expected future level of the index.

Events such as macro data releases, corporate earnings, and shifts in risk sentiment influence index futures as they mirror market expectations. Participants include institutional investors, hedge funds, banks, corporations, and retail traders. Common uses are hedging a stock portfolio against declines, price discovery, and directional speculation. Index futures carry leverage, so they enable large exposure with relatively small upfront capital, but also pose substantial risk if markets move against the position. Regulation and clearing standards are administered by national regulators and exchange-operated clearinghouses. The market for index futures began in the 1980s, led by S&P 500 futures introduced by the CME.
