Wpg, I pointed out they were buying big time starting early last week and asked Lunch why so many of their orders were for 100 shares. I now understand what Iceberg orders are. They must have one heck of a big Iceberg order on the books, as they have been buying for at least a week now. I think I can understand why somebody would want to diguise such a large order and as such have no problem with this type of program trading. The thing that bothers me is when you see 99, 01, apparently just passing shares back and forth with no real net position change. Anyone have an idea as to how many shares house 72 has bought in the last week. Citibank had a big iceberg going last week as well, so maybe they will take over when 72 is done.
