Will stocks listed in both Hong Kong and the U.S. go down and up at the same time, because the investors are different?

Will. The U.S. and Hong Kong stocks are different up and down, although the U.S. and Hong Kong stocks have a great deal of influence on each other, but there are still some differences between the two, the trend is not completely synchronized. But at some point in time the trend will have some similar, but there are still different, U.S. and Hong Kong stocks up and down different factors, and the market environment is also different.
