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 born in London in 1894, and immigrated to the United States with his family as a young boy.

He received his undergraduate degree from Columbia University, where he studied finance and economics, and later went on to earn his MBA from the same institution.

Graham worked as a stockbroker and financial analyst before becoming a professor of finance at Columbia University, where he taught a number of influential students, including Warren Buffett.

What is the Book About?

Security Analysis is a comprehensive guide to analyzing and evaluating stocks, bonds, and other securities.

The book is divided into three main sections: the first covers the principles of security analysis, the second covers the analysis of common stocks, and the third covers the analysis of bonds and preferred stocks.

The main theme of the book is the importance of fundamental analysis, or the process of analyzing a company’s financial statements and other data in order to determine its intrinsic value.

Graham argues that by carefully analyzing a company’s financials, investors can identify undervalued securities that offer the potential for long-term growth.
