In this fourth volume of The Deals of Warren Buffett, we trace Warren Buffett''s journey as he made Berkshire Hathaway the most respected company in the world.When we left Buffett at the end of Volume 3 toward the end of the 1990s, he was leading the largest corporation in America, and his personal fortune had reached $40bn. In this enthralling next instalment, we follow Buffett''s investment deals over the first few years of the twenty-first century, as Berkshire grew to be a giant making annual profits north of $8bn.Buffett, then in his seventies, was still tap dancing to work, thoroughly enjoying analysing companies, finding bargains and interacting with his growing team of managers.By studying the decision-making that went into his investment deals, and the successful and unsuccessful outcomes, we can learn from Buffett and become better investors ourselves.In this period, exploiting the low prices following the dot-com crash, Buffett made investments in the following companies: MidAmerican Energy, CORT, H&R Block, Moody’s, M&T Bank, Shaw Industries, Clayton Homes, McLane, PetroChina and Wal-Mart.For each of these deals, investing expert and Buffett historian Glen Arnold dives into unprecedented detail to analyse the investment rationale, the stories of the individuals involved and the profits Buffett made.
