China stock is the latest theme on the market

It seems no matter how the market does, up or down, recently, it does not affect the Chinese stocks traded on the US Markets. (CTDC), (CAAS), and (CESV) the examples of these Chinese company stocks. I believe this could be the latest craziness of the investment communities who wanted to play the hot China economy. For the past few days, these stocks became hot stocks. Volumes have picked tremendously and pushed them with very high percentage gains, some even with over 50% in a day. Play them with care.
