Buffett dumps Home Depot by Colin Barr @FortuneMagazine November 15, 2010, 9:55 PM EST E-mail Tweet Facebook Google Plus Linkedin Share icons Home Depot can’t help Warren Buffett. Berkshire Hathaway , the Omaha, Neb., company run by the billionaire investor, sold its entire Home Depot stake in the third quarter, according to a filing Monday with the Securities and Exchange Commission. Buffett says bye-bye Berkshire held 2.8 million Home Depot shares at June 30 and held as many as 5 million shares over the past decade, but didn’t list the Atlanta-based retailer in its quarter-end holdings. Berkshire’s quarterly filings detailing its investments are closely scrutinized because investors in Berkshire have received 20% compounded annually for more than 40 years, in part due to Buffett’s success as a stockpicker. Berkshire isn’t getting out of the home improvement game altogether. It continues to hold 6.5 million shares of Lowe’s , the North Carolina-based Home Depot rival. Home Depot isn’t alone in disappearing from Buffett’s portfolio. Berkshire also sold its holdings in auto dealer Carmax , document company Iron Mountain , energy provider NRG and garbage collector Republic Services . The positions Berkshire sold were worth $860 million at June 30. Meanwhile, Berkshire took a new position in financial custodian Bank of New York Mellon , buying almost 2 million shares worth $52 million at Sept. 30. Berkshire added to its position in Wells Fargo , the San Francisco bank that is the No. 3 U.S. mortgage player. It bought around 11 million shares during the third quarter, giving it more than 300 million shares. But Berkshire cut its stake in Moody’s , the credit rating company whose shares Buffett has owned for more than a decade, by 2 million shares to 28 million.
