Price difference among shares in Hong Kong and Shang Hai
These markets are independent, just like any other stock market. For example, there are stocks on the Milan stock exchange that are also on the New York stock exchange and have different historical prices. Remember, this is all about offer and demand. The Hong Kong stock exchange has the Hong Kong Dollar as its currency, which is anchored to the USD. Also, there is more trade going on, on the Hong Kong stock exchange. As for the answer, I don't know whether these stocks are exactly the same. I guess they should be, but maybe somebody else could answer that.
