The China market is pretty limited in reach; not many foreigners and not even many institutional investors; it is rife with insider trading and is pretty volatile. It is more like Macau than wall street. Still, dysfunctionalities in the Chinese economy that they were trying to hide with a stock market boom will now come in front and center, which will have some effect on the global economy. Especially in raw materials and energy, but even in some trade.

I'm quite worried about it personally.
