In late 2008, Berkshire bought 10% of BYD for $230 million. Munger has since said that he thinks the adoption of electric cars will take longer than many think, but he said he has plenty of faith in Chuan-Fu, and he and Buffett have been rewarded for that. Six years later, that 10% stake in BYD, which Berkshire still holds, is now worth nearly $1.8 billion.
2008年末,伯克希尔哈撒韦公司以2.3亿美元收购了比亚迪10%的股权。芒格后来说,他认为电动汽车的普及所需要的时间比许多人认为得要长,但他表示对王传福有充分的信心。而他和巴菲特的这份信任也获得了回报。六年后,伯克希尔哈撒韦公司至今仍持有比亚迪10%的股份,现在价值近18亿美元。
