The SmartMoney Map of the Market
The map lets you watch more than 500 stocks at once, with data updated every 15 minutes. Each colored rectangle in the map represents an individual company. The rectangle's size reflects the company's market cap and the color shows price performance. (Green means the stock price is up; red means it's down. Dark colors are neutral). Move the mouse over a company rectangle and a little panel will pop up with more information.
