I'm a tadpole, not an expert, and this is not advice, but...
I bought in last year on the basis that now Aussie and RAMS are each 100% owned by a major bank, the mortgage broking market space has no major, national, independent operator. I chose YBR as the best placed to move into that space.
1) Wide open national market space.
2) Mark Bouris has a proven track record in finance and maintaining a relationship with Macquarie Bank.
3) The business plan involved rapid development to maximize early-mover advantage.
4) Backed by Macquarie Bank.
Since then, also positive:
1) Business plan on track or ahead of schedule.
2) Development issues with new branches quickly identified and measures implemented to resolve.
3) Profitability expected in FY15.
So if you're planning to buy their lovely, wooly socks (w1londongroup), warm feet will probably cost more after their next annual report.
