????1988年，他以分拆调整后每股4美元的价格向政府支持的抵押贷款保险巨头房地美投资了1.08亿美元。当时巴菲特对这家公司有足够的信心。在投资房地美后不久，他在接受《财富》杂志采访时唱好这只股票。十年后，房地美股价升至70美元。但巴菲特在房地美的投资最引人注目的也许不是它当时的市场表现有多好，而是他选择出售这部分股权的时机。2000年，巴菲特作证称，他此前与房地美当时的CEO勒兰德?布兰德塞尔多次会面，期间意识到布兰德塞尔在争取两位数的回报，这是不明智的。

????巴菲特感觉到事情不妙，一年之内，伯克希尔哈撒韦公司抛售了所持房地美的所有股份。2003年，有消息称，房地美经常谎报其盈利。布兰德塞尔被迫离开。2008年，在全球金融危机伊始之际，房地美及其姊妹公司房利美（Fannie Mae）因为持有大量问题抵押贷款而濒临破产，不得不申请政府救助。房地美目前股价略高于2美元。

????Buffett had plenty of conviction when, in 1988, he invested $108 million in Freddie Mac, the giant government-backed mortgage insurance firm, at a split-adjusted $4 a share. Shortly after making the investment, he talked it up in the pages of Fortune magazine. Ten years later, Freddie Mac's shares traded at $70. But perhaps the most notable thing about Buffett's investment in Freddie is not how well it did, but when he sold. In 2000, Buffett testified that he had a series of meetings with Freddie Mac's CEO at the time, Leland Brendsel, in which it was clear to Buffett that Brendsel was unwisely striving for double-digit returns.

????That spelled trouble to Buffett and, within a year, Berkshire had dumped its entire stake in the company. In 2003, news came out that Freddie Mac had regularly misreported its earnings. Brendsel was forced out. In 2008, at the start of the financial crisis, Freddie Mac, along with its sister company Fannie Mae, was on the hook for piles and piles of unwise mortgage loans, and had to be bailed out by the government. Shares of Freddie Mac FMCC 1.98% now trade at just over $2.
