Omaha • Naysayers have been calling shares of Warren Buffett's company overpriced for decades.
But Berkshire Hathaway Class A stock, which first topped $1,000 in 1983, on Thursday surpassed $200,000.
"Everybody has now been proven wrong on it," said Andy Kilpatrick, who wrote "Of Permanent Value: The Story of Warren Buffett."
Berkshire has long had the most expensive U.S. stock. Buffett never split Berkshire's A shares, although he did create more affordable Class B shares in 1996 that now sell for nearly $135.
The stock has had its ups and downs. The Class A shares first hit six figures in October 2006 and peaked at $151,650 in December 2007, when the Great Recession began. They fell as low as $70,050 in March 2009.
