Before the open
You don't get the full picture watching one index. The S&P 500 doesn't move on its own. By the time it opens at 9:30, the news is out, the futures have been trading all night, and oil and bonds have already reacted. Traders who only watch the index are the last to know. Start with what's scheduled and what broke overnight, then watch how each market is taking it. Here are the five things worth a glance before the open, in that order, and what each one tells you.
1. The calendar and the news
Before any price, know what today is. Earnings before the open, the Fed at 2:00 PM, jobs on the first Friday, CPI mid-month: each one has a time, and the market goes quiet before it and loud after. Then the overnight headlines: an earnings miss, a tariff, a bank in trouble, a war. The scheduled events you can plan around; the breaking news tells you which sectors will be adjusting when the bell rings. Trader Tools has the countdown to every scheduled event.
What it tells you: what the day is about, and which markets to watch for the reaction.
2. The futures that trade while you sleep
The S&P 500 index (SPX) only prints during the day session. Its futures contract, the E-mini (ES), trades almost around the clock. So at 9:30 the futures already carry the overnight news: Asia, Europe, earnings released after yesterday's close.
The Micro E-mini (MES) is the same contract at one-tenth the size, which is why smaller accounts use it. Same for the Nasdaq-100: NQ is the full contract, MNQ the micro, and QQQ is the fund that tracks the same index during the day.
What it tells you: where the index is likely to open, and how far from yesterday's close.
3. Oil
Crude oil futures (CL) trade all night too. For a stock account, USO is a fund that roughly follows the price of oil. A sharp move in oil shows up in the index through energy stocks, airlines and anything that burns fuel, and a sustained rise feeds into inflation expectations.
What it tells you: whether an energy shock is part of today's story. Most days it isn't. On the days it is, it shows up across the index.
4. Bonds and the 10-year yield
The bond market often reacts first. The number to know is the 10-year Treasury yield. When it rises, borrowing costs rise and future profits are worth less today, which weighs most on growth and technology names. The futures contract is ZN; the fund many people watch is TLT, which moves opposite to the yield.
The 8:30 AM economic releases (jobs, inflation) hit bonds a full hour before stocks open. Watch the yield's reaction at 8:31 and you know how the stock market read the number before it has a chance to trade.
What it tells you: the direction of rates pressure, and the market's first read on the morning data.
5. The dollar and the fear gauge
Two quick ones. The U.S. dollar index (DXY) matters for companies that sell overseas; a strong dollar makes their sales worth less in dollars. The VIX measures how much movement option prices expect over the next month; a rising VIX means traders are paying up for protection.
What they tell you: VIX up with the index down is an ordinary selloff. VIX up with the index flat means someone is nervous before the move.
Putting it together: the two-minute morning glance
- Calendar and news: what's scheduled at 8:30, 10:00 and 2:00, and what broke overnight.
- ES/MES overnight: up, down or flat, and by how much. Is it reacting to the news?
- Yesterday's levels: is the market above, below or inside yesterday's high-to-low range, and how far from yesterday's close?
- 10-year yield: higher or lower than yesterday's close.
- Oil: anything unusual.
- VIX: higher or lower.
Read the first one, then watch the others adjust to it. That's the whole habit.
Then comes the open. The first 30 to 60 minutes of trading tend to show what kind of day it is: one that keeps moving in one direction, or one that goes back and forth inside a range. That's a page of its own, coming next.
None of this says what to do. It says what kind of day you're walking into, before the first candle prints.
