Testing capital asset pricing model (CAPM) in ho chi minh city stock exchange (HOSE), from traditional approach to conditional approach

Abstract

This study aims to test the validity of CAPM in Ho Chi Minh City Stock Exchange (HOSE). Two approaches employed in testing are (1) Fama & MacBeth’s traditional approach (1973); and (2) conditional approach developed by Pettengill et al. (1995). The research uses a time-series data set of all listed companies that are available on HOSE in each sub-period within the total sample period of 1/2007 through 6/2015. The results based on traditional approach show that CAPM does not offer a good explanation of risk-return relationship in HOSE. However, when considering market conditions (up/down) proposed by conditional approach, the findings are consistent with the CAPM prediction.
