Christopher Browne, a managing director at Tweedy Browne Company — the value investing firm that executed many of Benjamin Graham's original trades — wrote this concise and practical guide as a distillation of the value investing wisdom accumulated across nearly a century of practice at one of Wall Street's most distinguished firms. The book explains value investing in its most essential form: finding stocks that trade at significant discounts to their intrinsic worth, investing only when there is a meaningful margin of safety between price and value, and holding patiently until the market recognizes the value the analysis has identified. Browne covers the specific financial metrics value investors use — price-to-earnings ratios, price-to-book ratios, enterprise value to operating earnings — and explains why these simple measures have consistently identified above-market returns in research spanning multiple decades and dozens of international markets. He addresses common objections to value investing, including the concern that cheap stocks are cheap for good reasons, and explains the distinction between temporarily unpopular high-quality businesses and genuinely impaired businesses that deserve their low valuations. The book also covers the behavioral challenge of buying what is unloved and holding through further price declines before the eventual recovery. Brief, clearly written, and backed by genuine practitioner experience, this is one of the best pure introductions to classical value investing available.
