The Little Book of Common Sense Investing

Main Argument 1: The Inescapable Tyranny of Costs and the Loser’s Game of Active Investing At the very heart of John C. Bogle’s investment philosophy lies a principle so simple and so mathematically irrefutable that it is often overlooked in the complex and noisy world of modern finance. This central argument is that while investing in American business is fundamentally a “winner’s game,” the very act of trying to beat the stock market through active management turns it into a “loser’s game.” This transformation occurs not because of a lack of skill or intelligence among investment professionals, but because of

Main Argument 2: The Winner’s Game — Buy the Haystack, Not the Needle Flowing directly from his powerful indictment of active management as a “loser’s game” doomed by costs, John C. Bogle presents his elegantly simple and profoundly effective solution. If trying to beat the market is a futile and expensive endeavor, the most logical and successful strategy is not to play that game at all.

Bogle’s final and perhaps most encompassing argument moves beyond the specific mechanics of what to buy into the essential philosophy of how to be a successful long-term investor. This argument is a comprehensive guide to building a resilient, lifetime investment program. It posits that true investment success is not achieved through clever tactics or complex products, but through adherence to a set of timeless, common-sense principles. The core of
