The Simple Investing Trick That Beats Wall Street Pros

What if the secrets to building real wealth were hidden in plain sight? In this article, we explore the transformative ideas from The Little Book That Still Beats the Market by Joel Greenblatt — and how you can apply them to your own financial journey.

Joel Greenblatt’s The Little Book That Still Beats the Market is a beginner-friendly guide to systematic value investing, written in a simple, conversational tone. In it, Greenblatt introduces his “Magic Formula”—a rules-based strategy to buy good companies at bargain prices—that historically delivers market-beating returns with low effort and emotional involvement.

Although designed for everyday investors, the ideas are grounded in deep value investing principles and Greenblatt’s experience as a successful hedge fund manager and Columbia Business School professor.

The Magic Formula: Two Core Metrics

Greenblatt’s formula ranks stocks based on two criteria:

1. High Return on Capital (ROC)

Measures how efficiently a company uses its capital to generate profits.

Formula:

EBIT / (Net Working Capital + Net Fixed Assets)

A high ROC indicates a “good business”.

2. Low Price Relative to Earnings

Measures how cheap the stock is relative to its earnings.

Formula:

EBIT / Enterprise Value (EV)

This is a modified earnings yield. A high value means the stock is “on sale”.

Together, these two metrics aim to find good companies at good prices—the core of successful value investing.

How the Magic Formula Works

  • Start with a universe of companies (usually U.S. stocks >\$50 million in market cap).
  • Eliminate financials and utilities due to their atypical capital structures.
  • Rank all companies based on ROC and EY (earnings yield)
  • Buy 20–30 stocks from the top-ranked list (best combos of high ROC and high EY)
  • Hold each for 1 year, then rebalance annually
  • Repeat for 3–5+ years to realize long-term outperformance

Key Concepts & Takeaways

Consistency Over Time Beats Flashy Bets

  • The Magic Formula doesn’t work every year, but beats the market over the long run.
  • It relies on the power of mean reversion and behavioral mispricing.

Why It Works: Behavioral Finance

  • Investors often overreact to bad news and ignore boring, unfashionable stocks.
  • Greenblatt’s system removes emotion, making it easier to buy stocks others avoid, even when it feels uncomfortable.

🕰 Patience Is the Edge

  • The strategy requires discipline to stick with it, even when it underperforms temporarily.
  • Many investors abandon the method too early, missing long-term gains.

“The secret is to buy good companies on the cheap—and then to wait.”

🧮 It’s Not About Timing the Market

  • Greenblatt emphasizes that trying to predict the market or macro trends is a loser’s game.
  • Instead, focus on buying quality businesses at attractive valuations, consistently.

Key Takeaways

Use simple, rule-based investing to avoid emotional mistakes

Buy companies with high returns on capital at low prices

Stick with the system—results come with patience and consistency

Avoid complex predictions and focus on individual company fundamentals

Even children (as Greenblatt humorously explains) could follow this method

Final Thoughts

The Little Book That Still Beats the Market offers a powerful yet simple investing strategy that combines quality and value, backed by decades of data. While it isn’t a get-rich-quick scheme, it gives everyday investors a proven system to beat the market—if they stay disciplined.
