The Quantitative Value Investing Philosophy


Quantitative value investing is a powerful investment strategy that combines the principles of value investing with a quantitative approach. Unlike traditional value investing, which relies heavily on subjective analysis and qualitative factors, quantitative value investing relies on data-driven analysis and statistical models to identify undervalued stocks in the market. In this article, we will delve deeper into the philosophy behind quantitative value investing and explore the steps involved in implementing this strategy.

Quantitative Value Investing Defined

Quantitative value investing can be defined as an investment approach that aims to identify stocks trading at a significant discount to their intrinsic value by using quantitative metrics. This approach is based on the belief that stock prices often deviate from their true underlying value due to irrational market behavior, allowing astute investors to exploit these mispricings for profit.

An Introduction to Our Quantitative Value Index

At the core of quantitative value investing lies the quantitative value index. This index serves as a tool for screening and selecting stocks that meet specific criteria based on quantitative measures. These measures may include financial ratios, valuation multiples, and other performance indicators. By employing this index, investors can streamline their investment process and focus on stocks that offer the highest potential for long-term returns.

Step 1: Identify the Investable Universe

The first step in the quantitative value investing process is to identify the investable universe. This involves narrowing down thousands of stocks in the market to a manageable number that can be thoroughly analyzed. To accomplish this, investors may use filters such as market capitalization, liquidity, and sector-specific criteria to screen out stocks that do not meet their investment requirements.

Step 2: Remove Outliers

Once the investable universe has been established, the next step is to remove outliers. Outliers are stocks that deviate significantly from the norm and may distort the results of the analysis. By excluding these outliers, investors can ensure that their analysis is based on a representative sample of stocks and avoid skewed conclusions.

Step 3: Value Screen

After removing outliers, the next step is to apply a value screen to identify undervalued stocks. This involves examining various valuation metrics such as price-to-earnings ratio, price-to-book ratio, and dividend yield. Stocks that meet predetermined criteria based on these metrics are considered potential candidates for investment.

Step 4: Quality Screens

In addition to value screens, quantitative value investors also incorporate quality screens into their analysis. Quality screens evaluate the financial health and stability of a company by considering factors such as profitability, leverage ratios, and management efficiency. By incorporating these screens, investors can further refine their selection process and identify stocks with strong fundamentals and a competitive advantage.

Step 5: Invest with Conviction

Once a pool of potential investment candidates has been identified through the value and quality screens, the final step is to invest with conviction. This entails conducting in-depth research and analysis on each candidate, considering both quantitative and qualitative factors. By investing with conviction, quantitative value investors have the confidence to hold onto their positions even during market volatility, with the belief that the intrinsic value of the stocks will eventually be recognized by the market.

Conclusions Regarding the Quantitative Value Investing Process

In conclusion, quantitative value investing offers a systematic and disciplined approach to finding undervalued stocks in the market. By combining quantitative metrics with value and quality screens, investors can identify stocks with the potential for long-term growth and outperformance. While no investment strategy is without risk, quantitative value investing provides a framework for making informed investment decisions based on objective data and analysis.

The 80/20 Principle of Quantitative Value Investing

The 80/20 principle, also known as the Pareto principle, is an essential concept in quantitative value investing. It suggests that 80% of the results are derived from 20% of the efforts or inputs. In the context of quantitative value investing, this principle implies that a significant portion of the returns can be attributed to a few carefully selected stocks that meet the predefined criteria. By focusing on these high-quality stocks, investors can optimize their investment portfolio and achieve outsized returns.


Quantitative value investing offers a systematic and data-driven approach to identifying undervalued stocks in the market. By following a structured process that includes steps such as identifying the investable universe, removing outliers, applying value and quality screens, and investing with conviction, investors can increase their chances of finding stocks with favorable risk-reward profiles. However, it’s important to note that no investment strategy guarantees success, and thorough research and analysis are necessary before making investment decisions.

Warren Buffett on Quantitative Investing

YouTube video

In a video transcript, Warren Buffett and Charlie Munger discuss the process of determining intrinsic value and making investment decisions. They highlight the importance of using multiple techniques and models, as well as relying on experience. Buffett emphasizes that investing is not a game that can be simply mechanized, and that it takes time and experience to become a great investor.

When calculating intrinsic value, Buffett mentions that there is no one easy method that can be applied universally. Instead, it requires a combination of techniques and models. He compares the process to evaluating the profitability of a farm, where various factors such as crop yield, costs, and future projections are considered. By estimating potential profits and having conservative assumptions, it becomes possible to determine how much one would be willing to pay for the farm.

Buffett mentions that the same principles apply to evaluating businesses. It involves understanding the competitive position, dynamics, and future prospects of the business. By looking at the ability to distribute cash or reinvest it at high rates, investors can determine the value of the business. Berkshire Hathaway, for example, focuses on increasing its ability to distribute cash year by year, which contributes to its overall value.

Buffett emphasizes the importance of evaluating future cash flows and making investments based on that assessment. He mentions that it is crucial to understand the specific business and its potential for growth. While some businesses may have better visibility into the future, others may require more careful analysis. The goal is to identify businesses that have the potential to generate cash or reinvest it at a higher rate.

However, Buffett acknowledges that investing requires a level of expertise and insight. It is important to be aware of one’s limitations and only invest in areas within one’s “circle of confidence.” Buffett advises against venturing outside of one’s expertise or making investments without a clear understanding of the business.

Overall, Buffett and Munger make it clear that investing is not a one-size-fits-all approach. It requires a combination of quantitative techniques, experience, and a thorough understanding of the specific business. While they acknowledge that it is impossible to accurately value all investments at all times, they emphasize the importance of identifying opportunities that have the potential to generate significant returns.
