How to Read the Map
A stock market heatmap helps answer three trading and investing questions quickly: which sectors are leading, whether gains are broad or concentrated, and which large-cap stocks are driving the index. Green clusters often point to sector strength, red clusters show areas under pressure, and mixed sectors can reveal rotation beneath a flat index headline.
Methodology Notes
The heatmap groups S&P 500 constituents by sector and industry. Each rectangle represents one company, tile area is based on market capitalization, and color is based on daily percentage change versus the previous adjusted close. StockTitan uses adjusted close data so splits and dividends do not create false heatmap moves. Data status is shown above the map and may be live or delayed depending on account tier.
Market Temperature is a 0–100 descriptive composite of three readings from this page: market breadth (40%), the cap-weighted index move scaled to a ±3% full-tilt session (40%), and the share of sectors trading positive (20%). The context line compares today's reading against the same formula computed close-to-close for roughly the past year of sessions, using current index membership. It summarizes how broad and how strong the current move is; it is not a prediction or a trading signal.
