Introduction to Futures Trading

Every futures contract specifies: the underlying asset (crude oil, S&P 500, wheat, gold), the contract size (e.g., 1,000 barrels of oil, $50 × S&P 500 index level), the delivery/expiration date (typically monthly or quarterly), and the tick size (minimum price movement). Contracts are standardized by the exchange, ensuring all participants trade identical terms.

The E-mini S&P 500 futures contract is one of the most popular. It's valued at $50 × the S&P 500 index. If the S&P is at 5,000, one contract controls $250,000 of exposure. The Micro E-mini, at $5 × the index, controls $25,000—more accessible for individual traders. One tick (0.25 index points) is worth $12.50 per E-mini or $1.25 per Micro.

Futures trade on regulated exchanges (CME Group is the largest) and are centrally cleared, meaning the exchange guarantees both sides of every trade. This eliminates counterparty risk—you don't need to worry about the other party defaulting. Trading occurs nearly 24 hours a day, Sunday evening through Friday afternoon, with a brief daily maintenance break.

Futures margin is fundamentally different from stock margin. Rather than borrowing money to buy securities, futures margin is a good faith deposit (performance bond) that ensures you can cover potential losses. Initial margin is the deposit required to open a position. Maintenance margin is the minimum that must be maintained while the position is open.

The leverage in futures is extreme. An E-mini S&P 500 contract controlling $250,000 in exposure might require only $12,000 in initial margin—roughly 20:1 leverage. A 1% move in the S&P 500 produces a $2,500 gain or loss per contract on your $12,000 margin. That's a 20% return on margin from just a 1% market move.

This leverage works both ways. A 5% decline in the S&P 500 represents a $12,500 loss per contract—wiping out your entire initial margin. In extreme moves, losses can exceed your margin deposit, meaning you owe the broker money. This unlimited loss potential makes strict risk management absolutely essential in futures trading.

Futures contracts have expiration dates, typically on a monthly or quarterly cycle. As expiration approaches, traders must decide: close the position before expiration, or let it settle. Physical settlement means actual delivery of the underlying asset (bushels of wheat, barrels of oil). Cash settlement means the profit or loss is paid/received in cash (standard for financial futures like stock index futures).

Most traders close their positions before expiration—less than 3% of futures contracts result in physical delivery. To maintain a continuous position, traders "roll" to the next contract month: closing the expiring contract and simultaneously opening the next one. The cost of rolling (the price difference between months) affects total returns for long-term holders.

Futures prices and spot prices converge as expiration approaches—a process called "convergence." Far from expiration, futures prices can differ significantly from spot prices due to carry costs (storage, insurance, financing). For financial futures, the difference between futures and spot prices reflects interest rates and expected dividends.

Stock index futures (S&P 500, Nasdaq 100, Russell 2000, Dow Jones) allow traders to bet on overall market direction. They're used by portfolio managers to hedge equity exposure, by speculators to trade market views, and by arbitrageurs to exploit price discrepancies between futures and spot markets.

Commodity futures include energy (crude oil, natural gas), metals (gold, silver, copper), and agriculture (corn, soybeans, wheat). These markets serve a vital economic function, allowing producers and consumers to manage price risk. They also attract speculative traders who bet on commodity price movements driven by supply/demand dynamics, weather, and geopolitics.

Financial futures include Treasury bonds, Eurodollars, and currencies. These are among the most liquid markets in the world, used extensively by banks, hedge funds, and multinational corporations to manage interest rate and currency risk. Individual traders can access these markets, but the economic forces driving them require specialized knowledge.

Risk management is not optional in futures—it's the difference between survival and ruin. Never risk more than 1-2% of your trading account on a single trade. If your account is $50,000, maximum risk per trade is $500-1,000. Set your stop-loss before entering, calculate position size accordingly, and never move the stop further from your entry.

Use position sizing based on volatility. If the E-mini S&P 500 is moving $50 per day (100 points × $50/point per contract), a one-contract position has daily swings of $5,000. On a $50,000 account, that's 10% daily volatility—far too much for most traders. The Micro E-mini ($5/point) reduces the daily swing to $500 (1%)—much more manageable.

Maintain excess margin well above the minimum. If initial margin is $12,000, keep at least $25,000-30,000 in the account per contract to avoid margin calls during normal market fluctuations. Markets can gap significantly overnight or over weekends, potentially blowing through stop-losses. Adequate excess margin provides a buffer against these events.
