Understanding Magic Formula Investing

Magic Formula Investing, pioneered by Joel Greenblatt, is a stock investment strategy that offers a systematic and straightforward approach to identifying quality, undervalued companies. It is designed to help both novice and experienced investors navigate the often-confusing world of stock selection and investing.

Key Principles of Magic Formula Investing

The beauty of the Magic Formula lies in its simplicity and focus on value. The strategy targets companies with high returns on capital and attractive valuations, emphasizing the importance of investing in fundamentally sound businesses. It’s not a get-rich-quick scheme; instead, it’s a disciplined investment strategy with a long-term orientation. Patience and adherence to the chosen stocks are crucial elements for realizing the potential benefits of this approach.

How Magic Formula Investing Works

The Magic Formula works by ranking companies based on their earnings yield and return on capital. In other words, it looks for quality companies that are being sold at a discount. Companies with the highest combined rank for these two metrics are considered the best investment opportunities and are subsequently added to the investment portfolio.

Requirements for Magic Formula Investing

The Magic Formula Investing process begins by selecting a list of large-cap stocks. Financial and utility stocks are excluded from the list due to their distinct financial structure and regulatory environment.

The next step involves calculating two key ratios for each stock: Earnings Yield (EBIT/EV) and Return on Invested Capital (EBIT/(Net Fixed Assets + Working Capital)). These ratios are then used to rank the stocks, with the highest-ranked stocks representing the best value.

It’s worth noting that Magic Formula Investing doesn’t consider macroeconomic factors, industry-specific risks, or changing market conditions. Therefore, this formula should be complemented with thorough research and analysis to make informed investment decisions.

Advantages and Disadvantages of Magic Formula Investing

Like any investment strategy, the Magic Formula has its pros and cons. On the plus side, it offers potential for higher returns, simplicity and accessibility, focus on quality companies, and helps mitigate emotional investing. On the downside, there are concerns about back-testing validity, potential oversights due to its simplicity, disregard for market conditions and company-specific factors, and the potential for overvaluation and underperformance. Thus, it’s essential to carefully weigh these factors before implementing Magic Formula Investing.

In conclusion, Joel Greenblatt’s Magic Formula Investing is a value investing strategy that strives to simplify the process of stock selection. By focusing on quality and value, it aims to guide investors towards potentially profitable investment opportunities. However, like all investment strategies, it’s not without its drawbacks and should be used as part of a broader, well-researched investment approach.

Applying Magic Formula Investing

Joel Greenblatt’s Magic Formula has been a popular investment strategy, enchanting the stock investment landscape with its simple yet effective approach. This strategy is grounded in value investing, a concept that places emphasis on acquiring valuable stocks at a price below their intrinsic value.

Implementing the Magic Formula in Your Portfolio

The Magic Formula is not just a theoretical concept but a practical tool that can be implemented in your investment portfolio. The first step in applying this formula is calculating the earnings yield and return on invested capital (ROIC) for each stock in your target universe. This process involves some financial analysis, but it’s crucial in identifying high-quality companies with attractive valuations.

Once you have calculated and ranked each stock based on their earnings yield and ROIC, the next step is selecting those that meet your criteria. This is where the Magic Formula truly shines, as it clearly distinguishes high-performing stocks from the rest.

The selected stocks should then be allocated a portion of your portfolio, taking into account your risk tolerance and diversification goals. It’s a dynamic process that requires regular monitoring and adjustments based on changes in rankings and other relevant factors.

The Magic Formula in Practice

The Magic Formula has been successfully implemented by various investors. Joel Greenblatt himself has reported impressive returns using this strategy in his personal portfolio. Numerous studies and backtested results also show that the Magic Formula has consistently outperformed the market over long-term periods.

Several mutual funds have adopted the Magic Formula strategy and have achieved positive results. It’s also gaining popularity among individual investors, with many sharing their success stories online and in investment forums.

However, it’s important to remember that while the Magic Formula can provide a good starting point, it doesn’t guarantee success. Investing is more than just numbers. It’s about understanding the business behind the stock, the industry it operates in, and the overall market conditions.

While the Magic Formula focuses on two key metrics – earnings yield and ROIC, other investment strategies offer different perspectives. For instance, Mohnish Pabrai’s Clone Investing Strategy offers a comprehensive guide on investing in high-quality businesses at reasonable prices.

Potential Returns from Magic Formula Investing

Historically, Magic Formula Investing has generated higher returns than the broader market. Average annual returns have ranged from 17.8% to 30%, demonstrating the potential of this strategy. However, these figures are based on long-term data and may vary based on market conditions and individual stock performance. As always, it’s recommended to conduct thorough research and consider the limitations of any investment strategy before implementation.

Investing in the stock market is a journey, and Joel Greenblatt’s Magic Formula can be a powerful compass guiding your way. However, like any strategy, it requires patience, discipline, and a good understanding of its principles to be successful.


Understanding the Magic Formula Calculation

Many ask, “How is the Magic Formula calculated?” The Magic Formula, as devised by Joel Greenblatt, ranks companies based on earnings yield and return on capital. The earnings yield is calculated by dividing a company’s earnings before interest and taxes (EBIT) by its enterprise value, while the return on capital is determined by dividing EBIT by the sum of the company’s net fixed assets and working capital. The companies are then ranked based on these metrics, with top-ranked companies considered attractive investment opportunities due to their undervalued or outperforming status.

The Magic Formula’s Performance in Varied Market Conditions

Another common query is, “Does Magic Formula Investing work in all market conditions?” Historical data reveals that Magic Formula Investing has proved effective in diverse market conditions over the long term. However, investors need to be aware that short-term market fluctuations and low interest rate environments might not favor this investment strategy. While it does not consider qualitative factors such as management quality or industry trends, when used in conjunction with other analysis and considerations, it can contribute significantly to an overall investment strategy.

Combining Magic Formula Investing with Other Strategies

“Can Magic Formula Investing be combined with other investment strategies?” Absolutely, Magic Formula can be integrated with other investment strategies to create a diversified and balanced portfolio capturing a range of market dynamics. However, investors need to understand that combining strategies includes additional complexity and risks, potentially making market timing and volatility management more challenging.

Kick-starting Your Magic Formula Investing Journey

So, “How can one get started with Magic Formula Investing?” Beginning with Magic Formula Investing involves selecting a broad range of stocks, calculating their Magic Formula metrics, ranking them based on these scores, and building your portfolio with the top-ranked stocks. Regular review and rebalancing of your portfolio is also crucial. However, remember that Magic Formula Investing is a long-term strategy, and maintaining the portfolio for at least five years can yield optimal results. As with any stock investment strategy, it’s essential to do thorough research and analysis before making any investment decisions. Consulting with a financial advisor is always a good idea.


In the world of stock investment, Joel Greenblatt’s Magic Formula has carved a unique niche. This systematic investment strategy focuses on high earnings yield and high return on capital, offering potential for higher returns, simplicity, and a disciplined approach for individual investors.

Key Takeaways and Future Outlook

The Magic Formula’s focus on undervalued, high-quality companies can guide investors towards a balanced and diversified portfolio. It’s a tool that, when used appropriately, can help investors navigate the complexities of the market and possibly achieve financial success. However, it’s important to bear in mind potential issues such as back-testing validity concerns, possible oversights due to the formula’s simplicity, and the risk of overvaluation and underperformance.

Who can Benefit from Magic Formula Investing?

Ideal for those interested in a systematic, disciplined approach to investing, the Magic Formula may prove beneficial for those committed to long-term success.

Balancing Potential Risks and Rewards

While the Magic Formula offers higher return prospects, investors need to consider potential risks as well.
