Every stock in the S&P 500 on one screen — tiles sized by market cap, colored by price performance. Pick a period from today’s session out to the last 90 days. Updated after every market close, and free.
Stocks are grouped by sector, then by industry. The bigger the tile, the larger the company’s market value — so the mega-cap heavyweights that move the S&P 500 itself dominate the view, just as they dominate the index. Green is a gain over the period you selected, red is a loss, and the deeper the shade, the bigger the move. Tap or hover any tile to see the company’s sector, market cap and exact return for the period. However you type it — S&P500, SP500 or SPX — this is the complete index heatmap on one screen.
A heat map earns its keep when you compare periods. A stock that is green today but deep red over 90 days is bouncing, not trending; a sector that is green across every period is carrying the market. Switch between today, the last week, 30, 60 and 90 days to separate one-day noise from the real trend — most free heat maps only show the day, which is exactly the comparison they leave out.
The S&P 500 is the broad large-cap picture. For the tech-heavy side of the market, the Nasdaq-100 Heat Map covers the 100 largest non-financial stocks listed on Nasdaq; for the bluest of blue chips, the Dow Jones Industrial Average Heat Map fits all 30 Dow stocks into a single glance. All three maps are free and update after every close.
Price tells you what moved. The members' Signals view of this same map shows where our oversold system is firing — see how Trifecta Signals works.
