What I think ( and I am an optimist), is that all of this high profile actions against corruption, speculative activities and new real estate regulations are aiming only to strengthen the market in a long term and establish confidence in foreign investors (end buyers and end users), which may be not so long term actually (keep in mind the speed), but from Cityscape onwards.
As for the DFM, let's face it: Lehman Brothers are filing for bankruptcy and all over the world markets are trembling down. Oil is around $93 which is very very low , but that also has explanations and measures are already taken:
OPEC cuts production : Dubai Chronicle
Gulf markets pummelled by Wall St crisis - Financial Markets - ArabianBusiness.com
What will help:
Sovereign Wealth Funds may change direction of investment flows : Dubai Chronicle
All if this maid be a bit difficult to understand if you are not reading news daily.
My conclusion is that we are at the end of the beginning, rather than the beginning of the end.
