| Summary/Abstract |
This paper investigates whether the efficient market hypothesis (EMH) fits the Chinese military market using the Sequential Panel Selection Method (SPSM) and the Panel KSS unit root test with a Fourier function. We obtain evidence for structural shifts and non-linearity in the stock prices of the military industry in the Chinese stock market. Because sharp shifts and structural breaks are taken into account, the unit root hypothesis for most listed companies is rejected. Our result suggests that the Chinese military market is inefficient because of such factors as defense reforms, friction in the stock market, and irrational investors. We provide investment implications to enable future stock price movements to be predicted based on past behavior and enable trading strategies to be developed to earn abnormal returns. Meanwhile, Chinese defense enterprises should continue to implement industrial reforms, change their bureaucratic culture, and develop a market-oriented workforce.
