The Stock That Ruined Warren Buffett's Week

Imagine losing a billion dollars in one week and not even flinching. If you're Warren Buffett, the chairman and chief executive officer of Berkshire Hathaway (NYSE: BRK-A  ) , you won't need much of an imagination.

Thanks largely to the post-earnings plummet of IBM (NYSE: IBM  ) -- which was the fourth worst performing component on the S&P 500 (SNPINDEX: ^GSPC  ) last week, down by more than 10% -- Buffett did just that. According to data supplied by Standard & Poor's Capital IQ, his company's top five equity holdings lost a total of $934 million from when the market opened on Monday until it closed for the weekend on Friday. That equates to a loss of $9.3 million an hour, $155,657 a minute, and $2,594 a second.
