Benjamin Graham born in London, England in 1894, he was an influential investor whose research in securities laid the groundwork for in-depth fundamental valuation used in stock analysis today by all market participants. His famous book, "The Intelligent Investor," has gained recognition as the foundational work in value investing. Graham's philosophy of buying stocks based on their underlying value rather than their current market price is still popular today and has been adopted by many successful investors.Graham's investment career began during the Great Depression, when he worked as a security analyst for several large banks. He soon recognized that most investors were focused on short-term price movements instead of the underlying fundamentals of a company, which often led to poor investment decisions. In response, Graham developed a methodology for analyzing companies based on their financial stability and future prospects, which became known as "value investing."Graham's teachings have had a lasting impact on the world of finance and continue to be studied by aspiring investors even decades after his death. By emphasizing the importance of understanding a company's business model and intrinsic value, Graham helped lay the foundation for modern stock analysis techniques used by professionals around the globe.
