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, or a scale for dividend yield, beta, or valuation percentile. Valuation percentiles compare each stock with its own 10-year P/E, P/S, P/B, or P/FCF history.

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.
