Trading in NVI over the last week has been dominated by Argonaut, which is a small Perth broker with a Hong Kong office.
They have bought about 65% of the shares traded, and were the broker involved in the recent bigger cross trades.
The only other buyer of any quantity was Macquarie Insto.
I would not read too much in to that. NVI is a longer term story and it will take some time to get going.
