The lack of any forceful comment from VTI on the success of the trial (I know they have announced '... the company is satisfied with the independently verified resoults') is a legitimate cause for concern and would lead to some holders selling. That, coupled with the imminent delisting will have shaken a lot of holders out. I know I was tempted to sell purely because of the hassle of having to go through a full service broker if I wanted to sell down the track.

I still reckon that VTI commands technology with an enormous commercial future - and will have win plenty of contracts to earn it and its shareholdes a pile of dosh. But without any major profitable contracts after so many years of trials and promise, I can understand a reluctance to keep holding.
