What is happening in China? Why is the stock market dropping so fast?

China itself is currently booming, with over expansion. If you are a Technical Analyst, I would say, that resistance was hit. Fundamentalists, would believe that the market has gone in a direction similar to the US. US is a primary market, China I believe is secondary. But what goes down must come up. So wait for the drop to reach its support and see if you can find anything to buy. Cheers to quick money.
