If you want to learn more about how to invest in a stock, check out the directory of Investing for Beginners articles I've written, sorted by topic or head over to my blog for more esoteric and advanced topics that aren't particularly appropriate for beginners. Whatever happens, remember that stocks are just one of many types of assets that you can use to build wealth and become financially independent. 
This section lists the number of stocks that have advanced and declined for the day with the volume of shares traded, as well as the number of new 52-week high and low stocks for each of the exchanges. The numbers include all active stocks for that day. For U.S. Markets, only NYSE and NASDAQ stocks are included, excluding ETF's. NYSE and NASDAQ stocks also exclude unit investment trusts, closed end funds, warrant stocks, preferred securities and any non-SIC classified stock. For Canadian Markets, only TSX and TSX-V stocks are included.
