Understanding the Core Philosophy of the Little Book that Beats Market
What is Value Investing?
Value investing is the foundation of Greenblatt’s methodology. It involves identifying undervalued stocks that are trading below their intrinsic worth. Investors practicing value investing aim to buy these stocks at a discount, expecting the market to eventually recognize their true value and appreciate accordingly.
The Magic Formula: Greenblatt’s Approach
At the heart of the book lies the "Magic Formula," a systematic investment strategy designed to simplify the process of finding good stocks at attractive prices. The formula ranks companies based on two key financial metrics:
- Earnings Yield: A measure of how much a company earns relative to its price.
- Return on Capital: An indicator of how efficiently a company uses its capital to generate profits.
By combining these metrics, the Magic Formula aims to identify companies that are both undervalued and have strong fundamentals, increasing the likelihood of above-market returns.
Key Principles of the Little Book that Beats Market
Focus on Simplicity and Discipline
Unlike complex investment models that require extensive data analysis, Greenblatt advocates for a straightforward approach. The Magic Formula is easy to understand and implement, making disciplined investing accessible to everyone.
Patience and Long-Term Perspective
Greenblatt emphasizes that beating the market requires patience. The strategy involves holding a diversified portfolio of selected stocks for several years, allowing the market to recognize their intrinsic value.
Rebalancing and Repetition
The strategy involves periodically rebalancing the portfolio—typically annually—to replace underperformers with new candidates identified through the Magic Formula. This disciplined re-evaluation helps maintain a focus on undervalued, high-quality stocks.
Implementing the Magic Formula: A Step-by-Step Guide
Step 1: Screening for Potential Investments
Use financial databases or stock screeners to identify companies that meet the following criteria:
- Positive earnings before interest and taxes (EBIT).
- A market capitalization above a certain threshold (e.g., $50 million).
- Sufficient financial data for calculation.
Step 2: Calculating Earnings Yield and Return on Capital
- Earnings Yield: EBIT divided by Enterprise Value.
- Return on Capital: EBIT divided by Net Working Capital plus Net Fixed Assets.
Step 3: Ranking and Selecting Stocks
- Rank all companies based on earnings yield (highest first).
- Rank all companies based on return on capital (highest first).
- Combine these rankings to get a composite score.
- Select the top-ranked companies for investment.
Step 4: Portfolio Construction and Management
- Invest equally across selected stocks.
- Hold positions for approximately one year.
- Rebalance and rebalance periodically, replacing stocks that no longer meet criteria.

Combining with Other Strategies
The Magic Formula can be integrated with other investment approaches, such as dividend investing or growth strategies, to diversify and optimize portfolio performance.

Staying informed about market trends, financial metrics, and the performance of holdings is vital for successful implementation.
