Stock futures are contracts that lock in a price for shares you agree to buy or sell at a specific date in the future

A stock future is a binding agreement between two parties: one agrees to buy a certain number of shares at a set price on a set date, and the other agrees to sell at that same price and date. You do not own the shares while holding the contract — you own the right (and obligation) to complete that trade later. The contract itself is what you buy and sell.

Stock futures trade on exchanges like the Chicago Mercantile Exchange (CME) and the Intercontinental Exchange (ICE). They are standardized — the contract size, expiration dates, and settlement rules are all set by the exchange, not negotiated between you and another trader. This standardization makes them liquid: you can enter or exit a position quickly because many buyers and sellers are active at any moment.

The price of a stock future moves with the price of the underlying stock, but it is not identical. A future on Apple shares, for example, will track Apple's stock price but may trade slightly higher or lower depending on interest rates, dividends, and how much time remains until expiration.

Key Takeaways

  • Stock futures are contracts to buy or sell a fixed number of shares at a locked-in price on a future date, and you can sell the contract before that date arrives.
  • You control a large position with a small upfront payment called margin, which means your gains and losses are magnified compared to owning the stock outright.
  • Futures expire on set dates — typically the third Friday of March, June, September, and December — and you must close or roll the position before expiration or take physical delivery.
  • Stock futures are used by professional traders and portfolio managers to hedge risk or speculate on price moves, but they carry higher risk than buying shares directly.
  • Individual investors can trade stock futures through a broker that offers futures accounts, which requires separate registration and often higher minimum deposits than stock accounts.

How margin and leverage work in stock futures

When you buy 100 shares of a stock at $50 per share, you pay $5,000. When you buy one stock future contract (which typically represents 100 shares), you pay a margin requirement — usually 5 to 15 percent of the contract's value, or $250 to $750 in this example. The exchange holds this as collateral, and you control the full $5,000 position.

This leverage cuts both ways. If the stock rises to $55, your $250 margin controls a $500 gain — a 200 percent return on your margin. If the stock falls to $45, you lose $500 on a $250 investment — a 200 percent loss. Your broker will demand additional margin (called a margin call) if losses eat into your collateral, and if you cannot pay, your position is closed automatically.

Leverage is why futures are riskier than owning stock. You can lose more than your initial investment. A stock investor who buys 100 shares at $50 and watches the price fall to $0 loses $5,000. A futures trader with $250 margin loses that $250 immediately and may owe more if the exchange's rules require it.

Expiration dates and what happens when a contract ends

Stock futures have fixed expiration dates. Most individual stock futures expire on the third Friday of March, June, September, and December. As the expiration date approaches, the contract's price converges toward the actual stock price — by expiration day, they are identical.

You have three choices as expiration nears: close the position by selling your contract to another trader, roll the position by selling the expiring contract and buying a later one, or hold until expiration and take physical delivery of the shares (or cash settlement, depending on the contract). Most traders close or roll before expiration because holding to delivery ties up capital and creates settlement complications.

If you forget to close or roll and the contract expires, your broker will typically settle it in cash — you receive or pay the difference between your contract price and the settlement price. You do not automatically own the shares unless you explicitly request delivery.

Hedging versus speculation: two different reasons to use futures

A portfolio manager who owns 10,000 shares of Microsoft might sell Microsoft futures to lock in a price and protect against a sudden drop — this is hedging. The futures position offsets losses in the stock position if the market falls. The manager gives up upside if the stock rises, but that is the trade-off for protection.

A trader who owns no Microsoft stock but believes the price will rise might buy Microsoft futures to profit from that move without putting up the full purchase price — this is speculation. The trader is betting on direction and using leverage to amplify the return. If the bet is wrong, losses are also amplified.

Hedging reduces risk; speculation increases it. Both are legal and common, but they require different mindsets. Hedgers accept lower returns in exchange for predictability. Speculators accept high volatility in exchange for the chance at large gains.

How stock futures differ from stock options

Stock futures and stock options both give you exposure to a stock without owning it, but they work differently. A future is an obligation — you must buy or sell at expiration unless you close the position early. An option is a right — you can choose to exercise it or let it expire worthless.

Futures require margin and can result in losses larger than your initial investment. Options have a fixed maximum loss: the premium you paid to buy the option. If you buy a call option for $2 per share and the stock falls to zero, you lose $2 per share — not more.

Futures are standardized by the exchange and expire on fixed dates. Options are more flexible: you can buy or sell them with different strike prices and expiration dates, and they trade on multiple exchanges with varying rules.

For most individual investors, options are more accessible because the maximum loss is known upfront and the margin requirements are lower. Futures are more common among professional traders and large institutions.

Opening a futures account and getting started

To trade stock futures, you need a brokerage account that offers futures trading. Not all stock brokers do — you may need to open a separate futures account or switch to a broker that specializes in futures, such as Interactive Brokers, TD Ameritrade's thinkorswim platform, or E-TRADE.

Futures accounts require more paperwork than stock accounts. You must sign agreements acknowledging the risks, and brokers often require a higher minimum deposit — typically $2,000 to $10,000, though some firms require more. You will also need to pass a suitability review, where the broker confirms you understand how leverage works and can afford potential losses.

Once your account is open, you can place orders just like you would for stocks, but you will see contract symbols (like ESZ23 for the E-mini S&P 500 December contract) instead of stock tickers. Your broker's platform will show the margin requirement, expiration date, and current price for each contract.

Costs and fees for trading stock futures

Futures commissions are typically lower than stock commissions — often $1 to $5 per contract round-trip (buy and sell). Some brokers charge per contract; others charge a flat monthly fee if you trade frequently.

You also pay the bid-ask spread, the difference between the price a buyer will pay and the price a seller will accept. For liquid contracts like the E-mini S&P 500, the spread is tight — often just a few cents. For less-traded individual stock futures, the spread can be wider, eating into your profit on small moves.

Margin interest accrues daily on the margin you use. If you hold a position overnight, your broker charges interest on the collateral, similar to a loan. The rate varies by broker and market conditions but is typically 5 to 10 percent annually.

Frequently Asked Questions

Can I buy stock futures on any stock?

No. Only stocks with high trading volume and strong institutional interest have futures contracts. The CME offers futures on individual stocks like Apple, Microsoft, Tesla, and Amazon, but not on smaller or less-liquid stocks. Check your broker's futures menu to see which stocks have available contracts.

What happens if I cannot pay a margin call?

Your broker will close your position automatically to cover the shortfall. You lose the remaining margin and any additional losses. If losses exceed your account balance, you may owe the broker money. This is why futures trading requires discipline and a clear exit plan.

Do I owe taxes on futures profits differently than stock profits?

Yes. Futures are taxed under Section 1256 rules: 60 percent of gains are taxed as long-term capital gains and 40 percent as short-term, regardless of how long you held the contract. This is often more favorable than stock gains, which are taxed based on your actual holding period. Consult a tax professional for your specific situation.

Can I use futures to replace buying stock?

Futures can give you stock exposure with less capital, but they are not a direct replacement. Futures expire and require active management. Stock ownership is passive — you buy and hold indefinitely. Futures are better for short-term tactical moves; stock is better for long-term wealth building.

What is the difference between a stock future and an index future?

A stock future is a contract on a single company's shares. An index future is a contract on a basket of stocks — like the S&P 500 or Nasdaq 100. Index futures are more liquid and widely traded, but they move with the overall market, not individual company performance.
