From personal experience I can say that the stock market of less financialized economies (like China, and to a lesser extent Germany) aren't that good for investing. As a proof just look at the performance of the US stock market (most financialized economy in the world) against the stock market of virtually any other country, you'll find out that the US stock market very often performs better. At the expense of the real, material, economy.

(Just to clarify I'm neither a financial expert nor a big investor, just somebody who's saving for retirement since the pension system in my country is a complete joke)
