Appreciate your post. My feeling is there are "accumulators and dumpsters". A long time back, professors used to say "for every buyer, there is a seller". That sounded good at the time but now I see it differently. I like to watch the big blocks as no one holds a gun to someone to buy whereas people sell for all kinds of reasons... positioning, tax losses, marriage /estate problems, to fund that new multi $ X vacation home or 85' Hateras (probably misspelled) etc. etc. An up-tick, down-tick here and there mean little to me. When someone with big bucks moves in, it is usually not by accident. They have an idea of why they are making such a commitment and we must assume are not buying to lose money. I understand that we all (including Mr. Buffett) make errors in judgment still I like to see big blocks purchased in companies in which I hold an interest.
By the way, another block of 25,000 shares around 12:35 EST and one for 75,000 shares around 12:50 EST took place.
