Abstract: There have been numerous studies that have attempted to explain the cross-sectional variation in average returns in developed and emerging markets. However, there is a dearth in the published evidence of research that has looked at frontier markets regarding this aspect. Sri Lanka is considered to be a frontier market and hence the objective of this study is to test the ability of the Carhart four-factor model to explain the variation in the cross-section of average stock returns in the Colombo Stock Exchange (CSE) and to evaluate it in comparison to the capital asset pricing model (CAPM) and the Fama and French three-factor model. The study finds that the four-factor model, incorporating the market factor, size factor, value factor and momentum factor, provides a satisfactory explanation of the variation in the cross-section of average stock returns in the CSE. Further, it is found that the four-factor model performs better than the CAPM and the three-factor model.
