Stock investing is filled with intricate strategies and approaches, yet some of the most successful investors have done little more than stick with the basics. That generally means using funds for the bulk of your portfolio — Warren Buffett has famously said a low-cost S&P 500 index fund is the best investment most Americans can make — and choosing individual stocks only if you believe in the company’s potential for long-term growth.

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.
