MimiTheKid is right. This is a hard time to invest wisely in. It's not just markets doing irrational things, its
governments moving markets with irrational policies. Unless you have inside information on what those policies are going to be (which
does happen, but probably not to you), your investments will be based on speculation about the mental states of politicians and bureaucrats.
At this stage, sheer wealth preservation is a worthy objective. If you can hold on to your money until things settle down, and invest it
then, you could do very well.
Soros's book
The new paradigm for financial markets: the credit crisis of 2008 and what it means is a good read, if you're into this sort of thing.
