share price suppressed...?

I was just speaking to my broker and he mentioned that whoever sold $50 of shares this morning might have been a broker because the brokerage involved would have been at least $19 give or take and most brokerage companies have minimum purchases of $200 or $300 so that prices are not manipulated. He said "who would sell $50 worth of shares? Either they want to keep a share down... Or they are that desperate for money!"lol
Could someone be that desperate..? The way Gillard has handled our money for last 5 years quite possible.
food for thought hey. I don't see management doing anything to help lift the share price apart from home brand press release yesterday that should have been presented better in my opinion. It was very important news not something that the secretary knocked up on an A4 and sent off to the ASX.
