Book Review: Buffettology & The New Buffettology

BuffetologyBuffettology: The Previously Unexplained Techniques That Have Made Warren Buffett the World’s Most Famous Investor

There are plenty of books about Warren Buffett available at any bookstore or library. What makes this one unique is that it is not written from the perspective of Warren Buffett’s cult following. After her divorce with Warren Buffett’s son, Mary Buffett capitalized on a rare opportunity to publish insider information about one of the richest people in the world and his investment strategies.

Rather than quote Warren Buffett’s shareholder letters to death like most authors, Mary sticks to the details of Warren’s investments, how he made each choice and how it worked out. She provides a lot of quantitative data that is useful for reverse-engineering Warren Buffett’s portfolio.

Information from this book definitely helped me refine a few aspects of my investing philosophy and my screening process. Mary is concise and unemotional, making this a quick and productive read.

This sequel to Buffettology updates Mary Buffett’s analysis of Warren Buffett’s investing strategies from the first book. It is a fine addition to the library of materials available about Warren Buffett, adding new investment decisions from his history that I had not previously read about. It also brings readers of the 1997 Buffettology up to speed on developments getting into the 21st century, when the bubble of the 1990s burst, hurting many portfolios, but creating new opportunities for patient value investors.
