Subject: OT: BRK vs. S&P
Sorry for an OT post on one of the two US Policy boards but I find it very interesting that the moment I started writing this post the S&P was up over 3.2%, a huge move, while BRK-B was up only 1.9%.

This is such a stark difference that it might be worth talking about or at least noticing it. Even more so as BRK-A at that very moment was up only 1.3%, as if either A shareholders did sell or especially B were bought (Now, a little later, that huge difference between A and B is gone). Are those big temporary differences saying something about who is buying A's and who B's? Though it's about Berkshire maybe nevertheless interesting?
