My one concern is that I was seeing these large trades occurring and it appears the pps was either steady or would keep falling gradually... so my initial thought was accumulation while it was holding pretty flat. But when I was seeing the continuing large orders as it was falling, then I wondered if an institution was selling.

Still I have not seen a very very large number of large blocks (10,000 to 20,000 and even a 90,000 & 100,000 trade) being done like this before. If I had, I did not really pay attention to it until now.

We shall see what happens tomorrow morning on opening. It was nice to see the day end as it did, although it seems a bit odd. Still I will take it.

My last thought on this is with it being this close to the FDA saying anything, I would not expect many would want to sell.
