Bloomberg created a series of data visualizations of Hong Kong’s Hang Seng Index, which tracks the largest companies in Hong Kong, illustrating how the composition of the index has shifted over time to list a greater number of companies incorporated in China. The visualizations list all the companies included in the index since 1997 and indicate what years they entered or exited the index, as well as where the company was incorporated. The visualizations also break down the Hang Seng Index by sector, such as energy, telecom, and real estate, to show how each industry’s composition has changed. Overall, the share of Chinese companies in the index increased from 5 percent in 1997 to 56 percent in 2017.
