Currently, we follow about 3500 to 4000 stocks that are traded either on NASDAQ, NYSE or AMEX exchanges. Furthermore, we filter out stocks that do not meet our criteria. The criteria is based on history of the stock and other indicators that we follow. Sometimes, we may exclude a stock because of limited trading history, inadequate daily trading volume, exceptional events, and based on other indicators we follow. We filter these stocks to ensure that we give our users good analysis that we feel comfortable with.
