If Roche withdraws their offer, make no mistake about it, this stock will get pummeled back down to where it was before they expressed interest. This is likely another case of a selfimportant management which has failed to deliver a healthy ROE trying to stay in power.
likewise, I covered way too early... This current bounce is due to all the suckers getting out of the stock who acted on sheisterboy's buy recommendation (along with all the other corporate media sheister buy calls) and GS covering their 10 million share short position.
I see this company treading water and then heading south once news is out on Life's Ion Proton machine.
The only sure money was shorting ILMN at $54/share and waiting until now to cover. However, only the insiders (Flatley and the ILMN hedgefund owners) new that Flatley wasn't going to show Roche the books. This was a scam all the way around.
