Understanding S&P 500 Futures

What Are S&P 500 Futures?

• S&P 500 futures are standardized contracts that allow traders to speculate on or hedge against the future value of the S&P 500 index.

• These contracts are traded on futures exchanges, like the CME (Chicago Mercantile Exchange).

• Each contract represents a set dollar value of the S&P 500 index, making it possible to gain exposure to the entire index without buying all 500 stocks.

How do they work?

• S&P 500 futures work by agreeing to buy or sell the index at a predetermined price on a specific date.

• Traders don’t own the underlying stocks. Instead, they profit (or lose) based on the price movement of the futures contract.

• These contracts are marked to market daily, meaning gains and losses are settled at the end of each trading day.

• Futures can be traded with margin, allowing investors to control a large notional amount with relatively little capital.

• Futures are often used to predict market direction before the regular stock market opens, especially during off-hours trading.

• If the market drops, losses in the portfolio are cushioned by gains in the futures position.

• Once the risk passes, the investor can unwind the hedge and stay fully invested.

Important Considerations

• Hedging isn’t free—it may reduce gains if the market moves higher while futures are short.
