The value premium in the Vietnamese equity market

In recent decades, the Efficient Market Hypothesis has been the subject of debate among professionals and academics. In this hypothesis, the value premium is a key aspect that challenges market efficiency. The main objective of this study is to comprehensively investigate the value versus growth anomaly in the Vietnamese market between 2013 and 2023. Based on the empirical data, value portfolios have yielded a greater average return than growth portfolios in the Vietnamese stock market during this period. Although their levels of market risk (measured by beta) are nearly the same, the added-risk level of value portfolios is substantially higher than growth portfolios. Therefore, the value premium in Vietnam is compensated for bearing a higher risk level, consistent with the risk-based explanation.
