What is a stock market heatmap?

A stock market heatmap shows every company as a tile sized by market cap and grouped by sector, with color encoding a chosen metric — so you can scan the whole market at a glance and see which sectors and megacaps are driving it.

What do the tile colors and sizes mean?

Tile size is market capitalization — bigger companies are bigger tiles. Color is the metric you pick: green-to-red for gains and losses on a return view (1-day, 1-week, YTD, 1-year…), or a valuation scale for P/E, price-to-book, dividend yield, or beta.

Which stocks are included?

You can switch the universe: the top 500 US stocks by market cap, all US stocks we track, the S&P 500, the Nasdaq 100, or the top 100 ETFs. Click any tile to open that company's quote page.
