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.

The S&P 500 figure in the cockpit at the top of the page is the official index's daily move, sourced from the SPY ETF, because the index level itself is not published on a live trade tape. The sector bars and the cockpit's "500 members average" are market-cap-weighted aggregates of the 500 constituents measured from StockTitan's price feed; they can differ from the index when the day's move is concentrated in a few large companies, such as a session with negative breadth but a higher index.

Market Temperature is a 0–100 descriptive composite of three readings from this page: market breadth (40%), the cap-weighted average move of the 500 members 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.
