Common Stocks and Uncommon Profits and Other Writings

Philip Fisher’s 1958 treatise, Common Stocks and Uncommon Profits, established the foundational framework for modern growth investing. It shifts the analytical focus from the transient movements of the ticker tape and simplistic balance-sheet metrics to the qualitative, human elements of a business. Fisher argues that the greatest investment returns are not found in statistical bargains but in identifying and owning shares of exceptionally well-managed companies poised for sustained expansion over many years, even decades. The book introduces the now-canonical idea of the “scuttlebutt” method—a rigorous process of gathering intelligence from a company’s ecosystem to assess its true competitive strength.

At the core of Fisher’s philosophy is his famous “Fifteen Points to Look for in a Common Stock,” a checklist for evaluating a company’s potential. These points probe deeply into managerial integrity, the quality of research and development, the strength of the sales organization, and the existence of a sustainable competitive advantage. He emphasizes the paramount importance of investing in businesses run by people of the highest character and competence, asserting that capital entrusted to mediocre management is capital at risk. The methodology is intensely research-driven, advocating for an investigative approach more akin to a private equity analyst than a passive market participant.

The text further elaborates on the critical investor discipline of knowing when to hold and when to sell. Fisher advises extreme patience with correctly chosen investments, advocating a buy-and-hold-forever approach for the truly exceptional enterprise, while prescribing swift divestiture upon discovering a fundamental error in the original thesis. He warns against the folly of over-diversification, suggesting that an investor’s knowledge and attention are finite resources best concentrated on a handful of superlative opportunities.

Fisher’s work created the intellectual scaffolding for the concentrated, quality-growth investing practiced by legends like Warren Buffett, who famously synthesized Fisher’s qualitative focus with Benjamin Graham’s quantitative discipline. The book’s enduring legacy is its elevation of investment from a financial exercise to a study of business quality and human judgment, making it essential reading for any serious investor seeking to understand the art of identifying extraordinary companies long before the market fully recognizes their value.

The reader consensus is sharply bifurcated. A dedicated cohort venerates the book as a timeless, foundational masterpiece of growth investing, praising its profound qualitative framework and historical significance. Conversely, a significant portion of reviewers finds the prose dry, the examples dated, and the central “scuttlebutt” research method largely inaccessible to the average retail investor, rendering the advice theoretically sound but practically difficult to implement without professional resources.
