Normally I'd agree with you but in this special case the question is:

WHY TODAY?

As I wrote before we had the Baroni pr which was declared as good news by IR, just four days later they publish the "bad" news about PDSG while in the same time the '584 gets revalidated - now comes the most important and strange point:

The pr speaks of calendar year 2009 from which half a year is over, thus a CEO has another half a year time to publish his assumption about the revenue - but he choose the 16th of July to tell the world PDSG will have problems to achieve the goals until the 31st of December! I can't see any duty demanding this.

By the way: Isn't it strange we have more volume in the first four hours than we had the last month? And does anyone think the sells are from those who bought because of Crossflo/PDSG and are getting disappointed now? And all those who are in because of the MMP won't sell ONE share just some days before the first of the patents gets revalidated.

Thus my logic tells me: Someone wants to buy a million shares without getting to much attention.

All IMHO
