I snaffled a few more of these before the close today, hoping for reasonable rebound next week.

Company is a little too complicated for me, so if anyone can set any of my figures straight, or add any pertinent info, that would be appreciated.

Profile:
Property development and investment.

63 income producing investment properties: 42% Office, 53% Industrial, 4% Hotel, 1% Car park.
99% leased.
Avg lease 7 years.

10 investment properties under development.

Avg debt 1.7 years.
43% geared.
Needs to refi 563m by 200906.

The chart shows a classic builders crack bottom around 20 days ago, and I am hoping that is is a confirmed builders crack, as there is nothing worse than a double bottom on a builder.

NB - Please DYOR, my research can be dated and inaccurate and I have frequently been proven far more incompetent than I believed myself to be.
This is not financial advice. Merely my potentially flawed reasons for being interested in the stock. My gearing ratio is unconventional.
