what is going on with rat

I am considering buying some RAT in light of the recent massive sell down, and I was looking for some feedback from existing shareholders (I don't want my RAT to turn into a big, fat, dirty stinking RAT, if you know what I mean). I notice the following positives: * 84% of the portfolio's income is derived from US Government departments * Buyback in place * confirmation on 8/8/07 of no exposure to the sub-prime market * large discount to NTA * RAT indirectly owns an 80% holding in the Parkway Portfolio, which is one of the top performing REITs on the NYSE. So why then has the share price been belted so severely ? Is it market sentiment in general ? Is it negative sentiment directed toward REITS ? Surely in light of the above points, especially the income generated from the US Fed Govt tenants, RAT is a very defensive property portfolio with a great yield at the current low share price. Or am I missing something ???????
