The "sells", "purchases", or whatever you want to call them happened over quite a spread, so it involved a LITTLE more money than that. :) But that's exactly my point, if you WERE a big buyer, where would you want the bulk of buying done? Down here, where it's cheap. I hypothesize that many of those large block "sells" were actually transactions between MM's, ultimately getting them to someone's big buyer.
