The Impact of Market Liquidity on Stock Returns: Empirical Evidence from the Vietnamese Stock Market

The stock market plays an increasingly important role in restructuring the economy in Vietnam. Among many evaluation criteria, market liquidity is one of the essential factors showing the development of the stock market. This study aims to understand the influence of market liquidity on the performance of the Vietnamese stock market from 2011 to 2020. The research results show that market liquidity positively affects the Vietnamese market's excess return, and this result is unchanged with control variables. This finding contrasts with the liquidity risk premium theory, but it contributes to the debate over the role of investor sentiment in the markets.
