Sector Performance, Ranked Best to Worst
Sector change is market-cap weighted, which means larger companies have more influence on their sector's heatmap reading than smaller constituents.
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.
