A stocks heatmap is a visual representation of the stock market's performance, using colour coding to display the relative gains or losses of stocks within a specific index, sector, or market. Typically, green indicates price increases, while red signifies declines, with varying intensities reflecting the magnitude of the change. Stocks heatmaps help traders and investors quickly identify market trends, sector performance, and standout stocks, offering a comprehensive overview of market sentiment and dynamics at a glance. They are widely used for informed decision-making and portfolio analysis.
