ES futures explained: what moves the E-mini S&P 500 (and when to watch)

ES is the whole S&P 500 squeezed into one contract. It trades nearly all day and night, but it really wakes up at 9:30 am ET.

What moves it

ES is a bet on the whole US stock market at once. So it reacts to anything that changes how people value US companies.

• The Fed. The FOMC meets 8 times a year. The statement comes out at 2:00 pm ET and the press conference starts at 2:30 pm. Rate news can move ES a lot in minutes.
• Inflation. The CPI report comes out at 8:30 am ET, an hour before the stock market opens. ES is already trading, so it reacts first.
• Jobs. The monthly jobs report (usually the first Friday, 8:30 am ET) often sets the tone for the day.
• Big tech earnings. A few very large companies make up a big slice of the index. When they report after the close, ES can move in the evening session.
• Bond yields. When long-term interest rates jump, stock values often get squeezed. See how interest rates affect stocks.

When it's busiest

ES trades almost 24 hours, but the action isn't spread evenly.

• 6 pm–3 am ET (Asia hours): usually quiet, small candles.
• 3 am–8:30 am ET (Europe): activity picks up.
• 8:30 am ET: big data days can jolt it here.
• 9:30 am–4:00 pm ET: the US stock market is open. This is where most of the volume is.

CME sets its hours in Chicago time, and Chicago and New York change clocks together, so the ET hours stay the same all year. What shifts is when Europe and Asia open in ET terms, for a few weeks each spring and fall when daylight saving dates don't match.

Its personality

ES is one of the most traded futures in the world. That has a few honest effects.

• Deep and smooth. Lots of buyers and sellers means small gaps between prices most of the day.
• Respects big levels. Round numbers and yesterday's high and low are watched by many traders at once.
• Slower than NQ. It usually moves less in percentage terms than the tech-heavy Nasdaq contract.
• Quiet nights, loud opens. A calm overnight chart can turn fast at 9:30 am.
• Expires quarterly. Contracts run out in March, June, September and December. Most traders roll to the next one about a week before.

Reading it with our method

Start on the bigger chart. Mark the last places price turned around on the daily and 1-hour charts. Is it making higher highs and higher lows, or the reverse? Trade with that direction.

Then drop to your entry chart. Only a candle body closing past a level counts. A tail poking through, very common at 9:30 am, doesn't.

Set your stop from the chart first. Then work out your size. Example: your stop is 8 points away. That's 32 ticks × $12.50 = $400 of risk for one ES contract. If your plan says risk $100, one ES is too big, and the micro contract fits better. Use the futures tick value calculator to do this math fast. A math example, not a promise.

Common mistakes

• Sizing from the account, not the stop. One ES tick is $12.50. A 10-point stop is $500 per contract. Do the math before you click.
• Trading the 8:30 am spike. Data candles can whip both ways in seconds. Many traders wait for the first few candles to close.
• Forgetting the roll. An old contract gets thin near expiry. Check you're on the front month.
• Treating the overnight range as the real range. Levels set at 2 am ET often get run through once the stock market opens.
