it's official - vpg is not being manipulated

I sent a query to ASX about the recent trading activity on VPG including the open/close trading and they've come back to me.

Quote:

"Surveillance has reviewed the recent trading in VPG and notes the 1 share difference on the buy and sell side during the auction period.

"This appears to be the result of traders reducing their bids in order to get a lower matching price from the auction process.

"The strategy is intended to achieve a lower price when buying than otherwise would have been the case if the Participant had bid for 1 more share than was entered. This is an outcome which presumably most Participants would seek to achieve. Such trading is permissible and is not considered manipulative or inappropriate.

I guess as long as the activity is part of a 'strategy' it is fine.
