Warren Buffett made his reputation through his listed holding company Berkshire Hathaway. The company employs more than 350,000 people worldwide. The company is diversified in sectors as different as textiles, insurance, energy, transportation and industry. Warren Buffett and his trusted sidekick Charlie Munger are both major shareholders of Berkshire Hathaway. When Warren cannot or will not buy a company as a whole, he takes equity stakes in those companies. This thematic list shows only his U.S. listed holdings based on the 13F published quarterly on the SEC (Securities and Exchange Commission) website. These quarterly reports list the assets under management of investment managers or listed holding companies with control over more than $100 million in assets and which hold so-called "long" US positions. The Form 13F covers Registered Investment Advisers (RIAs), banks, insurance companies, hedge funds, trust companies, pension funds and mutual funds. This report is published no later than 45 days after the end of the relevant quarter. This list includes only US positions. Indeed, these funds or holding companies are only obliged to report shares traded on a US stock exchange. This list will be updated after each publication of the composition of the Berkshire Hathaway holding's listed portfolio.
