Abstract

The purpose of this study is to examine the presence of structural breaks, efficiency and volatility of frontier markets of Southeast Asia. Using daily and weekly returns of four composite indices (VN Index, HNX Index, LSX Index and CSX Index) we measure the presence of price volatility in the markets of Vietnam, Laos and Cambodia. Our findings from all unit root, autocorrelation, run and variance ratio tests suggest that the Vietnam stock market is weak-form inefficient, while, for the cases of Laos and Cambodia the empirical statistics produce inconclusive results. Furthermore, symmetric volatility models are statistically significant in both daily and weekly series implying that the impacts of positive and negative news or shocks are the same in magnitude.
