The 100 largest non-financial stocks on the Nasdaq, 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.
The Nasdaq-100 is the growth engine of the US market, and it is concentrated: a handful of mega-cap technology names account for an outsized share of its value. On this map they take up the space they deserve — tiles are sized by market cap, grouped by sector and industry. 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. Also searched as the NASDAQ100 or NDX heat map — same 100 stocks, same map.
Because the index is so concentrated, this heat map doubles as a sentiment gauge for the market’s favorite growth names. On a red day, check whether one giant name is dragging the picture or the weakness runs across the whole grid — then stretch the period to 30 or 90 days to see whether the longer trend agrees with today, or today is just noise inside it.
For the broad market, the S&P 500 Heat Map covers all 503 large-cap stocks across every sector; 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.
