Introduction to Magic Formula Investing
Magic formula investing is a simple yet effective value investing strategy introduced by investor Joel Greenblatt. This strategy has gained widespread popularity due to its promising track record and relatively easy-to-understand principles. At its core, magic formula investing is designed to help individual investors outperform the stock market using large-cap stocks with attractive earnings yields and strong returns on capital.
Origins of Magic Formula Investing:
The magic formula strategy was first introduced in Joel Greenblatt’s bestselling book “The Little Book That Beats the Market,” published in 2005. Greenblatt, a renowned investor, hedge fund manager, and business professor, based the strategy on two key criteria for stock investing: earnings yield and return on capital.
Understanding Magic Formula Strategy:
Rather than conducting traditional fundamental analysis of companies, magic formula investors rely on a quantitative screening process. They use a stock screener to identify companies that fit specific criteria and follow a methodical, unemotional approach in managing their portfolio over time. The strategy’s primary focus is on large-cap stocks and excludes small-cap companies, finance companies, utilities, and foreign companies.
The magic formula strategy’s unique selling point lies in its simplicity and the potential to outperform the stock market. It aims to buy good companies at cheap prices and holds them for a year before rebalancing and repeating the process. The key metrics for this strategy are earnings yield and return on capital, which are calculated differently:
1. Earnings Yield (EBIT ÷ Enterprise Value): This is determined by dividing each company’s earnings before interest and taxes by its total value. A higher earnings yield indicates a more attractive investment opportunity.
2. Return on Capital (EBIT ÷ [Net Fixed Assets + Working Capital]): This measures how efficiently the companies generate earnings from their assets. A higher return on capital suggests a more profitable and effective business.
Investors following the magic formula strategy buy two to three positions in the top 20-30 companies each month, sell losers before the year’s end, and hold winners for a year before selling them to take advantage of reduced income tax rates on long-term capital gains. This disciplined approach helps minimize emotional decision making and adheres to a clear set of rules.
Advantages and Disadvantages:
The magic formula strategy offers several advantages: it is simple, easy to follow, and requires no specialized investment knowledge. It also reduces the influence of emotions and irrational decisions. However, like any investing approach, magic formula investing does come with some disadvantages: returns may not always meet expectations due to changing market dynamics or increased competition from other investors following the strategy. Some analysts have suggested enhancing the method by introducing additional variables or rebalancing more frequently.
In the upcoming sections of this article, we will delve deeper into the history of magic formula investing, its requirements for implementation, and real-life examples of its success. Stay tuned to learn how you can apply these principles to your own investment strategy.
Understanding the Magic Formula Strategy
Magic formula investing is a rules-based, value investing strategy developed by investor Joel Greenblatt. The strategy focuses on screening companies based on two criteria: earnings yield and return on capital. It ranks stocks using these metrics to find the best investment opportunities in large-cap stocks. In this section, we’ll dive deeper into how magic formula investing works.
The Magic Formula Criteria: Earnings Yield and Return on Capital
Magic formula investing uses two primary criteria for stock selection: earnings yield and return on capital. These metrics help investors determine a company’s financial health and profitability, serving as the foundation of the strategy.
1. Earnings Yield (EBIT ÷ Enterprise Value)
Earnings yield measures how much income an investment generates relative to its cost. In magic formula investing, earnings yield is calculated by dividing a company’s earnings before interest and taxes (EBIT) by its enterprise value. This metric gives investors insight into the percentage of earnings generated in relation to the total investment. A higher earnings yield indicates better profitability.
2. Return on Capital (EBIT ÷ [Net Fixed Assets + Working Capital])
Return on capital is another essential factor for magic formula investing, as it measures how efficiently a company generates earnings from its assets. This metric is determined by dividing the EBIT by the sum of a company’s net fixed assets and working capital. A higher return on capital signifies that the business effectively uses its resources to generate profits.
The Magic Formula Screening Process
Investors using magic formula investing screen stocks based on earnings yield and return on capital rankings. They start by setting minimum requirements for these metrics, then apply the filtering process to a list of large-cap companies. The top-ranked companies are selected for investment consideration.
1. Setting Minimum Criteria
Investors set specific criteria for earnings yield and return on capital when screening stocks. A common practice is to limit the search to companies with earnings yields greater than 8% and a return on capital above 25%. These minimums help ensure a solid foundation of profitability and efficiency for potential investments.
2. Filtering Companies
To apply the magic formula strategy, investors screen stocks by ranking them based on their earnings yield and return on capital metrics. They then select the top-ranked companies that meet the established minimum criteria. This process results in a list of the most promising investment opportunities.
Investment Strategy: Buying and Selling Stocks
Magic formula investors follow a disciplined approach when buying and selling stocks, aiming to minimize emotional decision-making. They buy shares in two to three top-ranked companies each month and hold them for at least one year. After one year, they sell their winning positions to take advantage of lower long-term capital gains tax rates. Losing positions are sold before the one-year mark to offset any losses against potential gains.
Advantages of Magic Formula Investing
The magic formula strategy offers several advantages for investors:
1. Simple and Accessible: The straightforward nature of the strategy makes it accessible to investors of all experience levels. With a few simple rules, anyone can begin identifying undervalued companies.
2. Emotionally Detached: Magic formula investing focuses on quantitative data rather than market sentiment or emotional reactions, helping investors make rational decisions.
3. Consistent Performance: The disciplined approach to stock selection and portfolio management enables consistent results over time, leading to potentially higher long-term returns compared to market averages.
4. Flexibility: Magic formula investing can be customized by setting different minimum requirements for earnings yield and return on capital or by rebalancing more frequently. This flexibility allows investors to adapt the strategy to their specific financial goals and risk tolerance.
Disadvantages of Magic Formula Investing
Despite its advantages, magic formula investing does have some drawbacks:
1. Overreliance on Data: While quantitative data is essential for value investing, relying too heavily on earnings yield and return on capital may overlook other crucial factors such as industry trends, competitive landscape, and management quality.
2. Market Saturation: As more investors adopt the magic formula strategy, it could become less effective due to increased competition and a potential increase in market efficiency. This could lead to lower returns or even underperformance compared to the overall market.
3. Lack of Diversification: The focus on large-cap stocks in magic formula investing limits diversification, potentially leaving investors vulnerable to sector risks and company-specific risk.
In conclusion, magic formula investing is a simple yet effective value investing strategy that teaches investors how to approach the stock market methodically and unemotionally. By focusing on earnings yield and return on capital, investors can identify undervalued companies and build a disciplined portfolio designed for long-term growth. While the strategy may not always produce the high returns of Greenblatt’s original publication, it remains an attractive alternative to passive index investing.
History of Magic Formula Investing
The evolution of magic formula investing dates back to 2005 when the strategy was first introduced in Joel Greenblatt’s book, “The Little Book That Beats The Market.” In this influential work, Greenblatt, an investor, hedge fund manager, and business professor at Columbia University, outlined a simple yet powerful method for value investing using two key criteria: stock price and company cost of capital. This strategy, which became known as magic formula investing, has since gained widespread popularity due to its success in generating impressive returns.
The magic formula is not a new concept but rather an effective application of value investing principles. It was inspired by the work of renowned investors such as Benjamin Graham and Warren Buffett, who emphasized the importance of purchasing stocks at discounts to their intrinsic value. Greenblatt’s innovation lies in his straightforward approach to identifying undervalued companies using quantitative screens rather than traditional fundamental analysis methods.
In the original publication of “The Little Book That Beats The Market,” Greenblatt presented annualized returns of over 30% for his magic formula strategy, which caught the attention of investors worldwide. This impressive performance was achieved by ranking stocks based on their earnings and yield, as well as return on capital, and implementing a systematic selling process to capture gains and offset losses.
Since then, numerous researchers have backtested the magic formula strategy with varying results, demonstrating annualized returns ranging from 9% to 30%. These discrepancies can be attributed to differences in data sources, time periods, and methodologies used for calculation. However, the consensus is that magic formula investing has outperformed the S&P 500 index, validating its potential as a valuable investment approach for both individual investors and professional portfolio managers.
It’s important to note that while the magic formula strategy has shown strong performance in the past, it does not guarantee future success. Market conditions change, and investing carries inherent risks. Therefore, it is crucial to understand the strategy’s underlying principles, limitations, and potential modifications before implementing it in your portfolio.
In conclusion, magic formula investing represents a significant contribution to the world of value investing. Its history of success, as detailed in Greenblatt’s book, has inspired countless investors to adopt its systematic approach for identifying undervalued companies and generating superior returns. By understanding the strategy’s origins, principles, and evolution, you will be well-equipped to make informed decisions about its potential application in your investment journey.
Understanding Magic Formula Investing: The Basics
To delve deeper into magic formula investing, it is essential to grasp its fundamental components and how they contribute to its success. In the next section, we will discuss these concepts in detail, including the criteria for stock selection, portfolio management, and the rationale behind the strategy’s proven effectiveness.
Requirements for Implementing Magic Formula Investing
Magic formula investing is a simple yet effective strategy that can be applied by individual investors to beat the market and secure promising returns. Developed by investor Joel Greenblatt, this rules-based investment method relies on quantitative screens of companies and stocks to identify those that fit specific criteria. In order to successfully implement magic formula investing, it’s crucial to understand its requirements.
Minimum Market Capitalization: To ensure a proper balance between risk and return, it is recommended that investors set a minimum market capitalization for their portfolio companies. The typical threshold for this should be higher than $100 million.
Company Exclusions: Greenblatt’s magic formula only applies to large-cap stocks, excluding financial and utility companies, American Depository Receipts (ADRs), and foreign companies. These exclusions are essential to maintain the strategy’s focus on value investing in a systematic manner.
Calculating Earnings Yield: To calculate earnings yield, investors need to divide each company’s earnings before interest and taxes (EBIT) by its enterprise value. This simple calculation allows for an accurate assessment of a company’s profitability relative to its market worth.
Calculating Return on Capital: Another crucial metric in magic formula investing is return on capital, which measures how efficiently a company generates earnings from its assets. To calculate this, investors must divide the company’s EBIT by the sum of its net fixed assets and working capital.
Ranking Companies: By ranking selected companies based on their highest earnings yields and highest returns on capital, investors can build a diversified portfolio consisting of strong prospects for value investing. This systematic approach helps to minimize emotional or irrational decision-making, ensuring that investments are made solely based on numbers and data.
Rebalancing the Portfolio: To maintain the success of the magic formula investment strategy, it is essential to rebalance the portfolio periodically by selling off losing stocks before the year term ends and winners one week after the year mark. This discipline allows investors to consistently reinvest in companies that are outperforming while minimizing losses on underperforming holdings.
In conclusion, magic formula investing offers a simple yet effective way for individual investors to beat the market by identifying undervalued or outperforming large-cap stocks through a systematic, rules-based approach. By following its requirements – setting a minimum market capitalization, excluding specific types of companies, calculating earnings yield and return on capital, and rebalancing periodically – investors can unlock the potential for attractive returns without being swayed by emotions or market fluctuations.
Calculating Earnings Yield and Return on Capital
A crucial part of the Magic Formula strategy is understanding how to calculate earnings yield and return on capital. These two metrics play a significant role in determining which stocks will make it into an investor’s portfolio. In this section, we will delve into the calculations for these two important variables.
Earnings Yield:
First, let us discuss earnings yield. Earnings yield is calculated by dividing a company’s earnings before interest and taxes (EBIT) by its enterprise value. The formula to calculate earnings yield is as follows:
Earnings Yield = EBIT / Enterprise Value
Enterprise value represents the total value of a company, which is typically calculated as market capitalization plus debt, minority interest, and preferred equity, minus total cash and cash equivalents. By using this calculation, investors can determine the earnings yield of each company they are considering for investment. A higher earnings yield means that the company generates more profits relative to its enterprise value, making it a potentially attractive investment opportunity.
Return on Capital:
The next metric we need to understand is return on capital (ROC). This metric measures how efficiently a company generates earnings from its assets. The formula for calculating ROC is as follows:
Return on Capital = EBIT / (Net Fixed Assets + Working Capital)
Net fixed assets refer to the value of a company’s long-term assets, while working capital represents the difference between a company’s current assets and its current liabilities. A higher return on capital indicates that the company is generating more earnings from its existing assets compared to other companies in the same sector or market.
Real-World Examples:
Now let us explore some real-world examples of calculating earnings yield and return on capital for two large-cap stocks: Microsoft Corporation (MSFT) and Alphabet Inc. (GOOGL).
Microsoft Corporation:
To calculate Microsoft’s earnings yield, we first need to determine its EBIT, which is reported as $68.9 billion in the fiscal year 2021. The market capitalization for MSFT on January 31, 2023 was approximately $2.4 trillion. To calculate enterprise value, we will add debt (approximately $70 billion) and minority interest (around $5.9 billion), then subtract cash and cash equivalents ($128.6 billion). Enterprise Value = Market Capitalization + Debt + Minority Interest – Cash
Enterprise Value = 2.4 trillion + 70 billion + 5.9 billion – 128.6 billion
Enterprise Value = 2.31 trillion
Microsoft’s earnings yield can now be calculated as:
Earnings Yield = EBIT / Enterprise Value
Earnings Yield = 68.9 billion / 2.31 trillion
Earnings Yield ≈ 0.0297, or 2.97%
For Microsoft’s return on capital, we need the EBIT value of $68.9 billion and net fixed assets ($95.4 billion) and working capital ($39.4 billion).
Return on Capital = EBIT / (Net Fixed Assets + Working Capital)
Return on Capital = 68.9 billion / (95.4 billion + 39.4 billion)
Return on Capital ≈ 0.12, or 12%
Alphabet Inc. (GOOGL):
Calculating Alphabet’s earnings yield begins with determining its EBIT, which is $97.6 billion for the fiscal year 2021. The market capitalization for GOOGL on January 31, 2023 was around $1.4 trillion. Similar to Microsoft, we will calculate enterprise value by adding debt ($158.9 billion) and minority interest ($7.6 billion), then subtracting cash ($129.4 billion).
Enterprise Value = Market Capitalization + Debt + Minority Interest – Cash
Enterprise Value = 1.4 trillion + 158.9 billion + 7.6 billion – 129.4 billion
Enterprise Value = 1.343 trillion
Alphabet’s earnings yield can now be calculated as:
Earnings Yield = EBIT / Enterprise Value
Earnings Yield = 97.6 billion / 1.343 trillion
Earnings Yield ≈ 0.0728, or 7.28%
For Alphabet’s return on capital, we use the same EBIT value and net fixed assets ($155.7 billion) and working capital ($104.4 billion).
Return on Capital = EBIT / (Net Fixed Assets + Working Capital)
Return on Capital = 97.6 billion / (155.7 billion + 104.4 billion)
Return on Capital ≈ 0.082, or 8.2%
By comparing the earnings yield and return on capital for these two tech giants, investors can make informed decisions about which stock might be a better investment based on these metrics.

Real-Life Examples of Magic Formula Investing in Action
Since its introduction in 2005, magic formula investing has proven to be a successful strategy for investors looking to outperform the market. In this section, we present two real-life examples demonstrating how the magic formula strategy was applied and what returns it generated over varying time periods.
Example 1: Magic Formula Investing from 2007 to 2015
The first example focuses on a hypothetical investor named John who decided to adopt Joel Greenblatt’s magic formula investing strategy in early 2007. At that time, the S&P 500 had just experienced a significant decline due to concerns over the housing market bubble and the impending financial crisis.
John invested in the top 30 stocks with the highest earnings yield and return on capital as of March 1, 2007. He rebalanced his portfolio annually by selling off losers before the year ended and winners one week after the new year started. The following table summarizes John’s portfolio composition during the first three years:
Year | Top 30 Stocks | Weight in Portfolio
——|————————|—————
2007 | NRG Energy, Inc. | 14.1%

These examples demonstrate how magic formula investing can yield strong results when applied consistently over multiple years, even in different market conditions. By following a disciplined approach that involves rebalancing annually, investors can benefit from the strategy’s ability to identify undervalued companies and outperform the broader market.
Modifications to the Magic Formula Strategy
Since its original publication in The Little Book That Beats the Market by Joel Greenblatt, the magic formula investing strategy has gained significant popularity for its simplicity and effectiveness. However, some investors have sought to modify the strategy or expand upon it to achieve even better returns. In this section, we will discuss a few potential modifications to the magic formula strategy.
1. Incorporating Additional Variables:
Although the original magic formula focused on two primary variables – earnings yield and return on capital – some investors have proposed adding additional metrics like price-to-sales ratio (P/S) or dividend yields to further enhance the investment process. By integrating multiple quantitative measures, investors can create a more robust screening framework that captures various aspects of company valuation.
2. Rebalancing Frequency:
The original magic formula strategy required an annual rebalancing schedule, but some researchers suggest that more frequent rebalancing (e.g., quarterly or semi-annually) could potentially lead to improved results. Increased rebalancing frequency enables investors to buy low and sell high more often while taking advantage of shorter-term market inefficiencies.
3. Modifying the Eligibility Criteria:
While the original magic formula excluded financial companies, utility stocks, and non-U.S. companies, some modifications may include these sectors. By expanding the investment universe to these groups, investors can potentially access a more diversified portfolio and capture additional value opportunities. However, it’s important to remember that adding new sectors introduces added risk.
4. Adjusting for Inflation:
Another modification involves adjusting earnings yield and return on capital calculations for inflation, ensuring that the strategy remains effective in the long run. By using real (inflation-adjusted) numbers instead of nominal figures, investors can better account for changing economic conditions and maintain a more accurate assessment of a company’s value over time.
5. Accounting for Taxes:
Finally, some modifications to the magic formula strategy include taking into consideration tax implications. For example, investors might choose to use after-tax earnings yields instead of pre-tax figures in their calculations or adopt specific tax-loss harvesting strategies to maximize their after-tax returns. By accounting for taxes, investors can make more informed decisions and potentially enhance the overall performance of their portfolios.
While modifications to the magic formula strategy may improve its potential returns, it’s important to remember that no investment strategy guarantees success. Each modification comes with its own set of challenges, risks, and complexities. As always, conducting thorough research, understanding the implications of each change, and carefully considering your personal financial situation are crucial factors when implementing any investing strategy.
