What is value investing?

Value investing is an investment strategy that involves picking stocks that appear to be trading for less than their intrinsic or book value. Value investors actively ferret out stocks they think the stock market is underestimating. They believe the market overreacts to good and bad news, resulting in stock price movements that do not correspond to a company’s long-term fundamentals. The overreaction offers an opportunity to profit by buying stocks at discounted prices—on sale.

Warren Buffett is probably the best-known value investor today, but there are many others, including Benjamin Graham (Buffet’s professor and mentor), David Dodd, Charlie Munger, Christopher Browne (another Graham student), and billionaire hedge-fund manager, Seth Klarman.
