Stock Market Map (a.k.a. market heat map or market tree map) is a visual representation stock market data. This specific map categorizes 550+ stocks with largest capitalization into sectors and industries. The top-level map consists of sectors of the entire market and all the industries under each specific sector. The second-level map starts with a specific sector and consists of all the industries and then all the individual company’s stock under each industry. It is an investment research tool let you quickly view the performance of different sectors, industries and individual companies. The size of the block in the map represents the values of the component (stock or industry) within the portfolio of its parent (industry or sector). The color of the block represents the daily price movement of the component. The overall performance of the entire stock market and/or individual sector can be easily grasped by a glimpse to the map by the color and size of the blocks.

Tapping a block brings up a popup box showing the name, daily closing price, daily gain, daily volume and the 13 week average volume of the sector, industry or individual stock. For stocks there are also the strength and momentum data tracking the short-term strength of the stock compared to other stocks in the market as well as the volume momentum of the price movement. The name of each component is labeled on top of each block. Double tapping any block from the top-level map navigates to the second-level map of the sector that the block belongs. Tap the back button on the title bar or the back button on the mobile device to navigate back to the top-level map.

Market data are updated every two to three minutes.

The prices, volumes, average volumes and other information of sectors and industries are calculated by Bull Laboratories ( The indexes are calculated based on the market capitalization (daily price multiplies shares outstanding) of the underlying components (stocks or industries) in the level.

Sector and Industry specific indexes allow investors to benchmark the performance of investment based on specific stock market sectors or industries. Just as all stocks tend to move based on the underlying factors that drive the overall market, stocks in a similar industry tend to move based on underlying factors that affect the industry. One of the most basic methods for understanding the risk of an investment portfolio is to determine its sector breakdown. Is the portfolio spread across different industrial sectors or is it concentrated in just a few? This provides a good indication of how an investment portfolio will respond to macroeconomic factors or industry trends.
