Not to give away all of the secrets, but I wouldn't worry about that too much until you see VFIN show back up sitting on their multiple 100 orders. That was when all of the shares were changing hands. It is well known that VFIN serves that purpose for issuers. Once they were gone, most worries were gone. If they come back again for an extended period of time...it's happening again.
Until then, I am waiting on the same things to happen...CE Mark approval, increased sales opportunities, share buy back program, and merger/acquisition. Too simplistic? Don't think so.
Go SNDY!!!
