Smart Money has a really cool tool. Go to Smart Money, click on Maps, and select “Market Map”. A window with a lot of different sized squares and rectangles will pop up. Each square or rectangle represents a different stock. The relative size of the square corresponds to the stock’s market share. The color corresponds to the price, green is up. The map is continuously updated to reflect current prices.
This tool allows you to quickly see what the market is doing at a glance and to see how any one particular stock may or may not be acting with the market as a whole.
