Tiles are sized by full market cap. The index itself weights each company by the shares that are free to trade, so closely held companies such as Berkshire Hathaway and Walmart are larger here than their index weight.

About the S&P 500 Heatmap
The S&P 500 heatmap shows every stock in the index on one map. Stocks are grouped into the 11 GICS sectors: Information Technology, Communication Services, Consumer Discretionary, Financials, Health Care, Industrials, Consumer Staples, Energy, Utilities, Materials and Real Estate. A tile's size is the company's market cap and its color is the price change.
Because the index is weighted by size, a handful of the largest companies decide most of its move on any day. The map makes that visible: you can see whether the index is up because most stocks are up, or because a few very large tiles are green while the rest are red. Click a sector name to zoom into it.

S&P 500 Heatmap FAQ
How do I read this heatmap?
Each tile is one stock. The tile's area is its market cap (or trading volume, if you switch "Size by"), and its color is the price change over the selected period: green for gains, red for losses, deeper shades for moves above 5% and 15%.
Which stocks are on the S&P 500 heatmap?
All constituents of the S&P 500. That is 503 stocks from 500 companies, because Alphabet, Fox and News Corp each have two share classes in the index. Both classes are shown, each sized by its own shares. The list is updated when S&P adds and removes companies, which happens a few times a year.
What are the 11 sectors of the S&P 500?
Information Technology, Communication Services, Consumer Discretionary, Financials, Health Care, Industrials, Consumer Staples, Energy, Utilities, Materials and Real Estate. They come from the Global Industry Classification Standard (GICS). Some placements surprise people: Amazon and Tesla are Consumer Discretionary, while Alphabet, Meta and Netflix are Communication Services.
Is tile size the same as a stock's weight in the index?
Close, but not exactly. Tiles are sized by full market cap. S&P weights each company by its float, the shares available to the public, so a company with large insider or family holdings has a smaller index weight than its tile suggests.
When does the S&P 500 heatmap update?
During US market hours (9:30 am to 4:00 pm Eastern) prices refresh every minute. Outside market hours and on weekends the map shows the last traded prices.
