Stewart points out that Japanese government efforts to prop up stock prices by buying stocks in 1992 failed after 2 years when the fundamentals did not support the government effort. Experts say that even if the stock prices recover in China in 2015 after government efforts to prop up prices, this will be temporary if the economic fundamentals do not support such high valuations. The Shanghai Stock Exchange has a P/E ratio of 37 and the Shenzen Stock Exchange has a P/E of 80, very high valuations. Earnings numbers from smaller companies in China are also unreliable increasing investor risk. Additional issues are the timing of the government's effort to promote a surge in the stock market in 2014-2015. It comes as real estate and housing prices are in a bubble and the economy is slowing rapidly.
