Jim Surowiecki has an excellent column on insider trading this week. He claims — without hyperlinks it’s hard to judge this, but I do trust him — that the increase in insider-trading prosecutions isn’t just a reflection of increased prosecutorial zeal, but actually reflects a real uptick in insider trading itself.
In April 2009, Marc Gunther wrote a glowing cover story for Fortune profiling hot Chinese automaker BYD, the recipient of hundreds of millions of dollars of Berkshire Hathaway’s money. The headline was “Warren Buffett takes charge” (charge, electric cars, geddit?), and two things were abundantly clear. The first is that Berkshire’s stake had catapulted BYD into the international spotlight and given the company invaluable credibility. And the second is that Charlie Munger was BYD’s biggest cheerleader, both before and after the stake was bought.
