But who was Benjamin Graham, and what makes his book so enduring?

In this blog post, I will share all about this book and the author, key ideas from the book, and how you can apply it to your own trading & investing journey.

About the Author

Benjamin Graham was a renowned investor and financial theorist who is often referred to as the “father of value investing.”

He was born in London in 1894 and immigrated to the United States with his family as a child.

Graham received his bachelor’s degree in economics from Columbia University and went on to earn his MBA there as well.

After graduation, he worked on Wall Street as a stockbroker and eventually started his own investment firm.

Graham’s investment philosophy was built on the idea that investors should focus on the intrinsic value of a company, rather than just its stock price.

This approach is known as value investing, and it involves identifying undervalued companies with strong financials and holding onto them for the long term.

What is the Book About?

The book is divided into four parts, each of which covers a different aspect of investing.

The first part of the book, “General Principles,” covers the core principles of Graham’s investment philosophy, including the importance of having a margin of safety, the difference between speculating and investing, and the role of diversification.

It also covers the importance of having a long-term perspective and the dangers of overconfidence.

The second part of the book, “Types of Securities,” covers the different types of securities that investors can choose from, including stocks, bonds, and cash.

It also covers the different types of stocks, such as growth stocks and value stocks, and how to evaluate them using fundamental analysis.

It also covers the role of professional money managers and how to evaluate their performance.
