Value investing is when you buy stock in firms whose share prices are lower than their fundamentals suggest they should be. Value investing is like purchasing shares currently on sale: When other investors realize what they’re missing out on, they’ll purchase up the stock, the price will go up, and you’ll profit.
A low P/E ratio, or price-to-earnings ratio, relative to other companies in the same industry is one quick indicator that a stock is being undervalued by the market. The P/E ratio is the stock price of a company divided by its earnings per share.
Today’s most well-known value investor is Warren Buffet. He learned this approach to investing from Benjamin Graham, his Columbia University professor, and mentor. After turning a few million dollars into billions in the stock market, Buffet popularized the concept of value investing.
