Stock Market Heatmap — Sector + Ticker Performance
A heatmap is the fastest way to read what the market is doing today: which sectors are rotating in, which are bleeding, where the volume is going. Tapeline's heatmap groups the scored universe by GICS sector, sizes each tile by dollar volume, and colours by 1-day performance. Hover any tile for the underlying Tapeline composite score.
Sector snapshot · 1D %
Full heatmap →Sector aggregate from a saved snapshot that can be an hour old or more, over prices delayed about 15 minutes. The in-app heatmap drills into each sector with per-ticker tiles sized by volume, coloured by 1D / 1W / 1M, and joined to the Tapeline composite.
How the heatmap is built
The data spine is the same ticker universe powering the scanner: about 11,500 US equities + ETFs. Prices are delayed about 15 minutes and re-read about every 60 seconds during US market hours. Each ticker is grouped under one of the 11 GICS top-level sectors (plus three Tapeline buckets for Commodities, Funds & ETFs, and Uncategorized) via services/sector.canonical_sector() — which collapses 51 raw upstream labels into the 13 actually- useful ones.
Tile size = dollar volume (price × volume) so a mega-cap like AAPL dominates Information Technology and a thinly-traded small-cap doesn’t skew the visual. Tile colour = 1-day percentage change, with five tone bands (extreme up, up, faint up, neutral, faint down, down, extreme down) so the rotation pattern reads instantly without you having to parse exact numbers. Hover for the precise 1D / 1W / 1M and the Tapeline score.
The full interactive heatmap with sector drilldowns + search lives at /app/heatmap (Pro+). The current macro regime is at /market-regime.
Common questions
How is this different from the Finviz / TradingView heatmap?
+
Two things. First, every tile is joined to the Tapeline composite score — so you see not just 'tech is up 1.4% today' but 'tech is up 1.4% today and these are the 5 highest-scoring names driving it'. Second, be clear on freshness: Tapeline's prices are delayed about 15 minutes, and this public page is a saved snapshot that can be an hour old or more. Same shape of visualisation, a different underlying join.
What sectors does Tapeline cover?
+
The 11 GICS top-level sectors (Information Technology, Communication Services, Consumer Discretionary, Consumer Staples, Energy, Financials, Health Care, Industrials, Materials, Real Estate, Utilities) plus three Tapeline buckets for Commodities, Funds & ETFs, and Uncategorized. Raw upstream feeds use 51 different sector labels; Tapeline normalises to a clean 13-bucket taxonomy.
Can I drill down into a sector?
+
Yes, on the /app/heatmap page — click any sector tile to expand into the per-ticker grid for that sector, sorted by dollar volume. Search for any symbol to highlight it across sectors. The public showcase above is a top-level sector view only.
How often does the heatmap refresh?
+
Prices are delayed about 15 minutes, and Tapeline re-reads them for every covered stock and ETF about every 60 seconds during US market hours. Scores are recalculated on each pass, but most of their inputs are daily readings, so a score usually changes about once a day. The public showcase above is a saved snapshot that can be an hour old or more. The in-app heatmap refreshes itself about once per pass during the US session (04:00-20:00 ET on trading days), so you do not need to reload it.
Does the heatmap include commodities and ETFs?
+
Yes — the Tapeline universe includes 80 equities + 32 commodity ETFs (gold, silver, oil, gas, ag, copper, uranium, miners) plus sector and broad ETFs. The Commodities sector bucket is separated from Materials so the rotation visual stays useful.
What tier do I need?
+
Stock market heatmap is a Pro feature ($8.25/mo billed annually, or $9.99/mo monthly). The 30-day Premium trial includes everything in Pro. Premium adds recent insider buys (SEC Form 4).
