Stock Heatmap

A stock heatmap is a visual market analysis tool that helps investors quickly understand how stocks, sectors, or entire markets are performing at a glance. Stocks are typically displayed as colored blocks, where the size may represent market capitalization and the color reflects price movement over a selected time period. Green often indicates gains, while red signals declines.

Stock heatmaps allow users to identify trends across the market without reviewing individual charts one by one. Investors often use them to monitor major companies such as Apple, Microsoft, and NVIDIA, while also tracking broader sectors like technology, energy, or healthcare.
