Introduction

Often described as the ‘Bible’ of value investing, “The Intelligent Investor” by Benjamin Graham is a must-read in the world of finance.

The highly acclaimed book was written in 1949 and is filled with Graham’s key lessons that have shaped how we think about investing today.

Graham teaches readers to invest in a disciplined and intelligent manner – with an emphasis on minimizing risk while maximizing returns. While this advice seems to be just common sense at first, you would be surprised at how few investors actually strive to follow these principles when they are investing in the markets.

The investing manual introduces several concepts, including ‘value investing’, the ‘margin-of-safety’ principle and ‘Mr Market’ – all of which have become hallmarks in the investment world.

In addition to these core concepts, Graham covers topics such as how to interpret financial statements, portfolio selection and management, the effects of inflation, and psychological considerations in investing.

In this summary, we will take a look at some of the key themes and principles from “The Intelligent Investor” and how you can use them to become a more ‘intelligent’ investor.

The Intelligent Investor Quick Summary

“The Intelligent Investor” is one of the most important financial books of all time and has been hailed as the “bible” of investing by famous investors like Warren Buffet.

The book differentiates between investing and speculation right off the bat, where an investment promises the safety of principal (initial amount invested) and an adequate return upon thorough analysis. At the same time, anything that doesn’t meet these requirements falls under speculation.

A key metaphor introduced in the book is “Mr. Market”, representing the capricious nature of the stock market. Investors are advised not to follow the market blindly but to make their own value estimates.

One of the central tenets Graham advocates for is the principle of “margin of safety”. This principle entails that there should be a significant gap between an investment’s intrinsic value and its market price, providing a safety net against poor decisions and market downturns.

The focus on the intrinsic value of investments forms the basis for the value investing approach that Graham strongly endorses – purchasing stocks significantly below their intrinsic value.

Graham further categorizes investors into defensive (passive) and enterprising (active). Defensive investors aim to preserve their principal with satisfactory returns, while enterprising investors commit more effort and risk for potentially higher returns.

Regardless of the type of investor, Graham emphasizes the importance of diversification in investment portfolios to mitigate risk and increase the likelihood of overall success.

Benjamin Graham – The Father of Value Investing

Benjamin Graham was a renowned economist and professional investor who has been labeled as the “father of value investing.” His revolutionary theories laid the foundation for disciplined investing, breaking from the prevailing attitude of speculation in his time.

Born on May 9th, 1894, in London, Graham emigrated with his family to New York City when he was just a year old. The youngest of three children, he had a difficult childhood, with his father dying when he was just nine and his mother struggling to keep the family afloat.

Graham’s first experience with the markets was not a pleasant one as at the age of 13, his other opened a margin account to buy US Steel stock. The ensuing panic of 1907 wiped the account out.

Despite the hardships, Graham excelled in his studies, eventually earning a scholarship to attend Columbia University, where he graduated second in his class in 1914.

Graham had a brief stint as a lecturer at Columbia before he ventured into Wall Street, beginning as an employee at the bond-trading firm, Newburger, Henderson, and Loeb. His keen interest in analyzing financial statements helped him rise quickly within the firm.

Graham had a knack for identifying undervalued companies with strong fundamentals, a trait that would later become the bedrock principle of his investment philosophy. During his time on Wall Street, he managed to amass a considerable personal fortune, demonstrating the practical effectiveness of his investment strategies.

In 1926, Graham co-founded the investment partnership Graham-Newman Corporation, serving as the firm’s chief investment officer until he retired in 1956.

During his tenure, he developed and refined his investment philosophy of purchasing shares in companies for less than their intrinsic value, a strategy now known as value investing.

The catastrophic market crash in 1929 and the subsequent Great Depression greatly influenced Graham’s views on investing. His experiences during this period underscored the importance of thorough analysis, conservative valuations, and a margin of safety.

These principles were articulated in his seminal works, “Security Analysis” and “The Intelligent Investor”, which continue to be must-reads for investors around the world.

Graham died on September 21st, 1976, aged 82, leaving behind a legacy of value investing that continues to be relevant today.

Warren Buffett, one of the world’s wealthiest individuals and a renowned value investor, has famously credited the book as a crucial influence on his investment strategy.

Criticism

While “The Intelligent Investor” is widely respected and has been instrumental in shaping the investment philosophies of countless individuals, it’s not without its critics. One of the common criticisms revolves around its perceived lack of applicability in the modern, fast-paced investment world:

Outdated: Some critics argue that the book, first published in 1949, is outdated. The financial landscape has evolved significantly since Graham’s era, with the emergence of complex financial derivatives, algorithmic trading, and other sophisticated investment strategies. Some of Graham’s ideas might not be as directly applicable in today’s context.

Complexity for Beginners: Despite being a guide for the average investor, some readers find the book quite dense and complex, especially those new to investing. The book delves into detailed explanations of numerous financial concepts and techniques that might be difficult for a beginner to grasp.

Value Investing Critique: The book’s strong emphasis on value investing has drawn criticism from those who believe in different investment philosophies, such as growth investing. Critics argue that strictly adhering to value investing as suggested by Graham may cause investors to miss out on high-growth companies that might not meet the stringent criteria of value investing.

Underestimation of Macro Factors: Some critics suggest that Graham’s approach tends to downplay the influence of macroeconomic factors, focusing instead on individual company fundamentals. In today’s interconnected global economy, macroeconomic factors can significantly impact investment performance.

Remember, no investment strategy is one-size-fits-all. Each investor should learn from various sources and tailor their approach based on their personal financial goals, risk tolerance, and investment horizon.

3 Lessons From The Intelligent Investor

Learn from Mr. Market, Don’t Follow Him: The “Mr. Market” metaphor is a crucial lesson in dealing with market volatility. Rather than being influenced by the market’s irrational behavior, take advantage of it. Buy when Mr. Market is overly pessimistic and sell when he’s overly optimistic.
Know Your Investment Style: Identify whether you are a defensive or enterprising investor and invest accordingly. A defensive investor prefers a more passive approach, while an enterprising investor is more actively involved.
Commit to a Long-term Approach: Avoid chasing short-term market fluctuations. Patience and a long-term perspective are crucial for successful investing.
