Price informativeness and state-owned enterprises: Considering their heterogeneity

State owned enterprises (SOEs) play a pivotal role in the world economy. However, how state ownership affects price informativeness is less-explored, much less the impacts of differing forms of state ownership. We find that the price synchronicity of SOEs is about 9.0% to 15.4% larger than that of non-SOEs, indicating that SOEs have less informative stock prices. Institutional environment and government regulations such as anti-corruption campaigns are important mediating factors in reducing price synchronicity, but the price synchronicity of SOEs is still significantly larger than that of non-SOEs. Differences in state ownership matters for price synchronicity. SOEs associated with local governments (SOELGs), as well as those represented by state assets management bureaus (SAMBs), have larger price synchronicity than non-SOEs. Although SOEs controlled by central governments (SOECGs) also have larger price synchronicity than non-SOEs based on univariate tests, this difference becomes statistically insignificant when controlling for other factors. SOEs are less likely to be publicly exposed for fraud, implying that state ownership provides a buffer for SOEs. Overall, we evidence that state ownership has an important role in deprecating stock-price informativeness, with the impact differing depending on whether SOEs are controlled by central or non-central governments.
