Tests of the random walk hypothesis for equity markets: evidence from China, Hong Kong and Singapore
AbstractThis study tests the random walk hypothesis for China, Hong Kong and Singapore. Using variance ratio tests, robust to heteroskedasticity and employing a recently developed bootstrap technique to customize percentiles for inference purposes it is found that Class A shares for Chinese stock exchanges and the Hong Kong equity markets are weak form efficient. However, Singapore and Class B shares for Chinese stock exchanges do not follow the random walk hypothesis, which suggests that liquidity and market capitalization may play a role in explaining results of weak form efficiency tests.
