Is possible to make 30-40% return and it also mean you can lose that amount of your investment.

Market look really bad. Most of my oversea fund is in red from 10-15%. Tempted to topup but the more I read about Subprime crisis, the less confidence I have about the market now.

I think the problem is really serious and it will probably last longer than expected. I will probably holding off for the time being.
