Berkshire Hathaway More Than Doubles Stock Sale: The Omaha-based holding company plans to sell 250,000 shares, up from an initial projection of 100,000, according to documents filed with the Securities and Exchange Commission. The increase suggests strong demand for the opportunity to invest alongside billionaire Warren Buffett. Buffett, Berkshire Hathaway Inc.'s chairman, has warned he wouldn't advise family or friends to buy Berkshire common stock at its current price of $33,200 a share. However, the increase in the size of the stock sale, which will consist of lower-priced Class B shares, shows some investors are ignoring his counsel. Buying Berkshire shares is viewed as a way of tapping Buffett's acumen. Berkshire holds Buffett investments in such companies as American Express Co., Salomon Bros. and Coca-Cola Co.
