Testing for Market Efficiency in Emerging MarketsEvidence from the Athens Stock ExchangeGeorge Filis is a Ph.D. candidate at Bournemouth University, UK and a Lecturer at New York College, Athens. E-mail: g_filis{at}hotmail.com, gfilis21{at}otenet.gr The purpose of this study is to test the efficiency level of the Athens Stock Exchange (ASE). It performs efficiency tests for the years 20002002. The results of these tests enable us to argue that over the two years of the study, ASE was not an efficient market as it suffered from volatility clustering. However, the FTSE/ASE 20 index showed evidence of weak form efficiency as it followed a random walk pattern.
Key Words: JEL Classification: C12 JEL Classification: G14 Asymmetric information efficiency implied volatility random walk
