Are eastern europe investment funds better then Asian/Latin American ones?

i want to invest in aggressive stock-based investment funds.
i checked Polish funds and they bring around 50%-60% yearly (30% for 6 months, 15% for 3 months). these funds are managed by well known institutions like Fortis and Commerical Union. And they are sold as umbrella funds so if the stock market goes down i can easily switch to bond-based funds.

now, as 50-60% they generate is the same or even higher then Asian and Latin American funds, plus the fact that European countries are much more stable (NATO, EU members), why would anyone want to invest in Chinese, Indian or Latin American funds at all ?

Your understanding of investment funds is either fantastic or you have just read a prospectus . Why you ask would we not invest in these products, simple risk and reward ratio with most of these funds they are off the scale. The 2;30 at Doncaster is a safer bet than most Eastern European indexes.China, the great communist state and India the new factory and office of the world. are no doubt great but highly volatile. Latin America was wonderful but what rises like a fountain goes down as quick, as can be seen by current returns.
Talk to a investment adviser don't listen to soothsayers

buy low & sell high, if its up 60% it might not be low
