The History and Evolution of Value Investing
Value investing, one of the most revered and enduring investment strategies, traces its roots back to the early 20th century.
Pioneered by the legendary Benjamin Graham and David Dodd in their seminal book “Security Analysis” published in 1934, value investing is based on the concept of buying undervalued securities and holding them for the long term, expecting their true value to be recognized by the market over time.
This strategy has stood the test of time, but it hasn’t stood still; value investing has survived by evolving and adapting to various market conditions over the decades, and finding innovative new ways to build upon the the basic principles involved.
The Beginnings of Value Investing
The foundation of value investing can be attributed to Benjamin Graham, often hailed as the “Father of Value Investing.”
Graham’s investment philosophy was heavily influenced by his experiences during the stock market crash of 1929 and the subsequent Great Depression. He realized that the market’s irrational exuberance could lead to significant mispricing of stocks, creating opportunities for shrewd investors to find undervalued gems.
In “Security Analysis,” Graham and Dodd emphasized the importance of conducting in-depth fundamental analysis of companies, focusing on their intrinsic value rather than short-term market fluctuations. They advocated the use of financial ratios, such as price-to-earnings (P/E) and price-to-book (P/B), to identify undervalued stocks with a margin of safety. This concept of a margin of safety became a cornerstone of value investing, offering protection against adverse market movements.
The Influence of Benjamin Graham’s Students
Several prominent investors and business figures emerged from Graham’s teachings, including Warren Buffett, Irving Kahn, Walter Schloss, and William J. Ruane. Each of these individuals embraced value investing principles and furthered its evolution. Warren Buffett, in particular, became the most successful and renowned proponent of value investing, gaining the title “The Oracle of Omaha.”
Buffett, a former student of Graham, adapted and refined value investing to suit his own investment style. He focused on buying high-quality companies with strong competitive advantages and holding them for the long term, borrowing some of the concepts associated with growth investing. Buffett’s success and impressive track record with his investment holding company, Berkshire Hathaway, further popularized value investing and solidified its place in the investing world.

Modern Portfolio Theory and Beyond
In the 1950s and 1960s, the field of finance witnessed significant advancements with the introduction of Modern Portfolio Theory (MPT) by Harry Markowitz and the Capital Asset Pricing Model (CAPM) by William Sharpe. These theories emphasized the importance of diversification and the concept of systematic risk. Some critics argued that value investing was outdated in the face of these new theories, as it focused on individual stock analysis rather than portfolio diversification.
However, value investing continued to thrive, as proponents argued that MPT and CAPM did not consider behavioural aspects of investors and the potential for irrational market behaviour. Whilst value investors do not select stocks solely to maximize their overall returns within an acceptable level of risk as with MPT and CAPM, they are still able to benefit from the effects of diversification, and they are still able to combine both high and low risk investments within their portfolio to target the desired level of risk and return.
Behavioural finance, a field that gained prominence in the 1980s and 1990s, shed light on the psychological biases affecting investor decision-making. Value investors found support in these studies, as they could explain the market’s tendency to overreact to short-term news, leading to mispriced stocks that value investors could exploit.
The Dot-Com Bubble and Its Aftermath
The late 1990s witnessed one of the most dramatic market bubbles in history—the dot-com bubble. Internet-based companies with little or no profits saw their valuations soar to astronomical levels. Many value investors, including Warren Buffett, refrained from participating in the speculative frenzy, deeming these investments too speculative and overvalued.
When the bubble burst in the early 2000s, value investors were vindicated as many dot-com companies collapsed, causing severe losses for investors who had chased the hype. This period reinforced the importance of value investing principles and its focus on investing in companies with solid fundamentals and reasonable valuations.
Value Investing in the 21st Century
In the 21st century, value investing has faced new challenges and criticisms. The global financial crisis of 2008-2009 brought into question the effectiveness of traditional value metrics in extraordinary economic circumstances. Some critics argued that the changing dynamics of the economy and technology-driven disruptions rendered value investing less relevant.
Furthermore, the rise of passive investing and exchange-traded funds (ETFs) presented new options for investors seeking low-cost, diversified exposure to the market. However, value investing has persisted, with proponents pointing to its long-term track record and its ability to outperform in certain market conditions.
To adapt to the changing landscape, some value investors incorporated elements of growth investing and quality investing into their strategies. This “hybrid” approach sought to identify undervalued companies with growth potential and strong fundamentals, combining the best of both value and growth strategies.
Conclusion
In conclusion, value investing has a rich and storied history, dating back to the early 20th century. Its core principles of buying undervalued assets and holding them with a margin of safety have remained steadfast over time. While facing criticisms and challenges along the way, value investing has proven to be a resilient and enduring investment philosophy, embraced by many successful investors worldwide. Its evolution continues as it adapts to new market dynamics and investor preferences while staying true to its fundamental principles.
