Questions This Page Answers
- Why Is the Stock Market Down Today?
- It isn’t. The SPY ETF is up 1.14% at $758.49 as of 11:03am ET. The biggest lift is chips and memory: the group is up 7.55%, which adds about 0.56 percentage points to the market. No major data release or Fed event is scheduled today.
- Does this page say what caused the move?
- It says where the move is: which sector groups and which stocks account for the market’s change, from live quotes across the 500 largest US stocks. It also names what was on the calendar that day: the major data releases (CPI, PPI, the jobs report, retail sales, GDP, PCE and the ISM surveys), Fed decisions and minutes, and earnings reports from the stocks moving the index. It does not read the news. A move driven by a headline, a tariff announcement or a comment from an official shows up here as the sectors and stocks it hit, not as the headline itself.
- Why can the market be down when most stocks are up?
- The market’s headline figures are weighted by market value, so the largest companies count for far more than the smallest. On our map of the 500 largest US stocks, the ten largest make up 38% of the total in the latest snapshot. A 1% move in the largest is worth more than a 10% move in a small utility. On a day when a few of the largest companies are down and most other stocks are up, the market can finish down. The breadth figure on this page gives the count of stocks down and up.
- How often does this page update?
- Every minute. The market move at the top of the page is the percentage change in the SPY ETF’s price, and the sector and stock breakdown comes from our map of the 500 largest US stocks. During the regular session, 9:30am to 4:00pm ET, the answer describes the live move. Before 9:30am it switches to SPY’s pre-market trading once enough stocks have traded. After the close it gives the day’s close and SPY’s after-hours move, and on weekends and holidays it describes the last session.
Fund and stock quotes are delayed feeds from Yahoo Finance, refreshed about once a minute, the same ones that color the heat map. Each group’s and stock’s contribution is weighted by market value across the 500 largest US stocks. SPY holds a slightly different set of companies, so the contributions add up to close to SPY’s move, not exactly to it. Data releases, Fed events and earnings dates come from the site’s verified calendar. Maintained by Atul Ghandhi. Times are Eastern. Nothing here is a recommendation.
