Berkshire Hathaway shares sag since Buffett says he's retiring
The stock had reached an all-time high just before Warren Buffett said he will step aside at the company he built.

Warren Buffett's retirement announcement was not what investors wanted.
During the middle of Thursday's trading, shares of Berkshire Hathaway (BRK.A) and (BRK.B) had fallen as much as 10.3% from all-time intraday highs of $812,855 and $539.80 on May 2.
May 2 was the day before some 40,000 investors and fans jammed the company's annual meeting, held in an Omaha, Neb., arena.
