In the past 12 months, shares of Warren Buffett’s Berkshire Hathaway (NYSE:BRK.A)(NYSE:BRK.B) have had a rare pummeling, down 15%, over double the decline of the S&P 500 (SPY). Since 2000, there have only been a handful of occasions where shares have experienced a trailing 12 month loss of this magnitude. Still, on every one of those occasions, Berkshire stock would have been a prudent buy.
