Then, by the principal component analysis method, all of the stock markets were divided into several different categories. The study demonstrated that the developed countries and the emerging economics were divided into two different categories in the long term of trend. For the four days’ short-term fluctuations, the United States and Europe were the same category, while Asia-Pacific countries were divided into the another category.
