In The Little Book That Still Beats the Market, Joel Greenblatt distills decades of experience into a concise, witty, and surprisingly approachable framework for beating the market. At its core, Greenblatt introduces what he calls the “Magic Formula”—a systematic way to buy good companies at bargain prices.
The book’s premise is refreshingly simple. “Buy good companies, cheap,” Greenblatt writes. “That’s it. That’s the secret.” But he doesn’t stop there—he explains precisely what “good” and “cheap” mean. A good company is one that “earns a high return on capital,” and a cheap company is one that trades at “a low price relative to earnings.”
To measure quality, Greenblatt uses return on capital: “It’s like saying, how good is this business at making money from its own operations?” For price, he turns to earnings yield: “Earnings yield tells you how much you’re paying for each dollar the company earns.”
The genius of the Magic Formula lies in combining these two metrics. Greenblatt ranks thousands of companies based on return on capital and earnings yield, then invests in those that rank highest in both categories. “By buying above-average companies at below-average prices,” he explains, “the magic formula found companies that did very well over time.”
While the formula may be simple, Greenblatt warns it’s not always easy to follow. “The hard part isn’t the math,” he notes. “The hard part is having the discipline and patience to stick with a strategy that doesn’t always work immediately.” Market noise, volatility, and underperformance in the short term can shake the confidence of even seasoned investors.
That’s why Greenblatt emphasizes long-term thinking: “If you’re not prepared to stick with a strategy for at least three to five years, you probably shouldn’t be investing in stocks at all.” He encourages investors to focus on process over outcome, reminding readers that “good strategies don’t work all the time. If they did, everyone would use them.”
Among the most reassuring lessons for everyday investors is Greenblatt’s confidence in their ability to succeed: “Individual investors have a huge advantage over professionals. You can afford to be patient.”
In the end, Greenblatt’s book is less about magic and more about method—providing a data-driven, repeatable approach to finding bargains in the stock market. “The truth is, it’s not magic. It’s just common sense.”
