buy - sell ratio, page-9

Hi All,
I just read a little about YBR on Motley Fool.
Looks like it has great potential exposure to an ongoing low interest rate environment. Especially when the big banks appear to be already fully priced.
I'm amazed at the number of branches they have, and know that Mark Bouris was very succesful with Aussie Home Loans.
Forecast maiden profit in FY 15 sounds like soon would be a good time to buy.
Can anybody tell me any more?
How can they do a share buy back if they are not yet in profit?
What is the involvement of Mac Bank?
Thanks in advance.
