Security Analysis, the revolutionary book on fundamental analysis and investing, was first published in 1934, following unprecedented losses on Wall Street.
Benjamin Graham and David Dodd chided Wall Street for its myopic focus on a company's reported earnings per share (eps), and were particularly harsh on the favored "earnings trends." They encouraged investors to take an entirely different approach by estimating the rough value of the operating business that lay behind the security. They have given actual examples of the market's tendency to irrationally under-value certain out-of-favor stocks.
The book is must read for any Stock Market Investor, fundamental analyst or equity research professional.
