See the entire S&P 500 as an interactive treemap, color-coded by performance and sized by market cap. Track sector rotation, spot momentum divergences, and read the market at a glance — the same visualization used on institutional trading floors.
Quick Answer
The Market Heatmap is a free map of the S&P 500.
Each of the 500+ stocks is a box (a treemap), grouped by sector. The bigger the company, the bigger the box. Color runs from deep green (strong gains) to deep red (heavy losses), so sector trends, momentum shifts and concentration risk stand out at a glance. Prices come from TradingView and are delayed on its free tier.
Price data comes from TradingView's embedded widget for all S&P 500 constituents, US ETFs, and major cryptocurrencies. It refreshes while the page is open and is delayed per TradingView's free tier — not a live exchange feed.
Each stock's percentage change is computed against the previous close. Gains and losses are normalized to produce accurate color intensity mapping.
Stocks are grouped into 11 sectors. Block size is proportional to market capitalization — larger companies like AAPL and MSFT occupy more visual space.
Deep green indicates strong gains (>3%), light green modest gains, light red modest losses, and deep red significant losses (>3%). Color intensity reflects conviction level.
Figures come from Financial Modeling Prep (FMP) and are shown with their source and date.

The heatmap uses a green-to-red color scale to represent stock performance. Deep green indicates strong gains (typically above +3%), light green shows modest gains, light red means modest losses, and deep red signals significant losses (below -3%). The intensity of the color reflects the magnitude of the price change, letting you quickly gauge market sentiment at a glance.
The heatmap refreshes while the page is open using TradingView's embedded widget. That data is delayed per TradingView's free tier — for US stocks it can be end-of-day rather than intraday — so treat it as a market map, not a quote feed. Outside of market hours, the heatmap displays the most recent closing data.
The heatmap covers all 11 sectors: Technology, Healthcare, Financials, Consumer Discretionary, Consumer Staples, Energy, Industrials, Materials, Real Estate, Utilities, and Communication Services. Stocks are grouped by sector so you can instantly see which sectors are leading or lagging.
Block size represents market capitalization. Larger companies like Apple (AAPL) and Microsoft (MSFT) have bigger blocks because they represent a larger share of the index. This weighting mirrors how the S&P 500 index itself is constructed, giving you an accurate visual representation of market impact.
