Heatmap

A colored map of the market. Box size is company size, color is how much the stock moved. Green means up, red means down.

The heatmap shows the whole market at a glance. Each box is a stock. Big companies get big boxes. Green boxes are up, red boxes are down, and the brighter the color, the bigger the move. Stocks sit inside their sector and industry, so you can see which part of the market is carrying the day.

How to read the S&P 500 heatmap

  1. Click Heatmap in the left menu. It opens on S&P 500 with Today colors.
  2. Find the big boxes first, such as the largest tech names. They move the index.
  3. Look at the color of each sector block. A mostly green sector means money is flowing in.
  4. Check the legend at the bottom for the color scale.
  5. Click any stock box to open its research page.

The map shows the 60 largest companies in the view and refreshes about every minute.

How to look inside a sector

  1. Click a sector name, such as TECHNOLOGY, on a computer.
  2. A panel slides in from the right with the sector's top 10 movers by % change.
  3. Click a row to open that stock, or close the panel with its X.

On a phone, tap a stock to open it. The sector panel is a computer feature.

How to change the time range (Pro)

  1. Use the range buttons at the top: Today, 1W, 1M, 3M, 6M, YTD and 1Y.
  2. A stock that is red today but green over a year is a pullback. Red on both is a stock in trouble.

Free accounts see Today only. The other ranges show a lock.

How to switch to sectors or crypto (Pro)

  1. Click Sector ETFs to see the eleven sectors as ETFs.
  2. Click Crypto for a coin map. It has its own ranges, 1H, 24H and 7D.

Free accounts see S&P 500. The other views show a lock and a note that they are Pro views.

Good to know

  • Box size is market cap and color is the percentage move. A big box that moves 1% matters more to the index than a small box that moves 5%.
  • Use the heatmap first, then Movers or the Scanner to find individual names.

If something doesn't work

  • The map is empty or slow: it can take a moment on the first load. Reload the page.
  • A view is locked: Sector ETFs, Crypto and the longer ranges are Pro. Free accounts keep S&P 500 and Today.
