China's movements cause ripples across the world

Again today, all eyes were on the Shanghai Composite Index, which led the advance across the Asian region with a rise of 4.52 percent to close at 2912.

China's largest market has become the barometer, not only for Asian stocks, which seem to mirror its movements on an almost daily basis, but also for the U.S.'s S&P 500. Surprisingly, the S&P and the Shanghai Composite now have an 80 percent correlation.
