Value Investing is an investment strategy that involves picking stocks that appear to be trading for less than their intrinsic or book value. Investors who follow this approach, like Warren Buffett, believe that the market often overreacts to good and bad news, leading to stock price fluctuations that do not reflect a company's true value. By focusing on fundamental analysis, value investors seek to identify undervalued companies with strong fundamentals, such as solid earnings and low debt. This strategy aims for long-term gains, as these stocks are expected to appreciate over time once the market corrects its mispricing.
