A note on weak form market efficiency in security prices: evidence from the Hong Kong stock exchange


  • Kwong-C. Cheung
  • J. Andrew Coutts


This paper employs variance ratio tests with both homoscedastic and heteroscedastic error variances to examine the random walk hypothesis for the Hang Seng Index on the Hong Kong Stock Exchange. The empirical investigation leads us to suggest that the Hang Seng follows a random walk model and consequently that the index is weak form efficient. This conclusion offers both confirmatory and conflicting support for the conclusions of previous research, which has investigated the presence of random walks in the indices of both developed and emerging markets.
