Oh yes, I noticed! I'm sorry for my poor bank. But a few bucks is (are?) a few bucks. And a man must eat to live. I remember from a Men's Health in a waiting room somewhere that Simon was quoted as saying something like "I'll trade stocks or goats or Enron employees..." I suppose that sums it up. As a matter or pure academic interest / useless speculation, what would bring about a movement like that. Because it's only the market makers who trade the last 10 mins. Does it just mean that one of them had to sell a lot of shares in a hurry? And how would that happen? A (big) client goes short at 16h49 30'?
