Basically, FXI trade in a wide range in the last 10 years, as shown in the chart. Although valuation seems cheap after -20%+ slump in 2018, I suggestion investors take cautions when considering investing in this mainland ETF, as economic slowdown show no sign of abating. the fundamentals of China's growth has stretched far and exhausted because of high debt and capital misallocation. Government has been scrambling to bump up the economy since summer, while the central bank has take a more accommodating monetary policy ,but I consider these measures will take some time to substantiate.
