Value stock investors look for companies whose stock appears to be undervalued. It could be considered undervalued based on sales, earnings, dividend yield, etc.
Value stocks are usually older stocks that pay dividends and tend to be less risky and volatile as growth stocks, though they also tend to offer less opportunity for large returns.
Beware though, Value Stock Investor, there are things out there called VALUE TRAPS. This is when stocks appear to be cheaper than they really are, but are actually suffering from huge company problems or industry problems, which would depress the stock price.
