This study aims to examine the relevance of foreign ownership to stock return volatility in the Vietnam stock market over ten years (2008 - 2017). After applying the fixed effects regressions and the extended instrumental variable regressions with fixed effects, we find that foreign ownership decreases the volatility of stock returns. However, the stabilizing impact of foreign ownership on stock return volatility becomes weaker in large firms since the coeffcient of the interaction term between firm size and foreign ownership turns out to be significantly positive. The estimated results remain robust when we use the future one-year volatility, other than the current one, as an alternative measure of the dependent variable.

Stock Return Volatility

PurposeThis study investigates the impact of board independence on firm risk of Vietnamese listed firms and the moderating effect of capital expenditure on this relationship.Design/methodology/approachThis paper applies fixed effects and dynamic generalized method of moments (GMM) models to examine hypothesized associations between the proportion of nonexecutive directors and stock return volatility, as well as the moderating effect of capital expenditure. The robustness tests are implemented by applying alternative measures of overinvestment and firm risk.FindingsThe results show that the presence of nonexecutive directors on board increases firm risk. However, the combination of nonexecutive ratio and capital expenditure ratio has a significant negative impact on firm risk. The result is also confirmed by the difference between the monitoring role of nonexecutive directors in overinvesting and underinvesting firms.Research limitations/implicationsThe results imply that Vietnamese listed firms take stock return volatility into consideration before nominating and appointing nonexecutive directors into their board, especially in overinvesting firms. From another perspective, the shift toward having a majority of nonexecutive directors on boards can play a significant role in pursuing a stable or risky business strategy.Originality/valueThis paper investigates the influences of nonexecutive directors on firm risk in the context of Vietnam.

The Impact

AbstractThis study constructs a firm-level measure of large foreign ownership (LFO) and investigates its impact on stock return volatility in 31 emerging markets. We find a negative relationship between LFO and volatility, even after controlling for potential endogeneity and the impact of major domestic shareholders. This suggests a stabilizing role of LFO in emerging markets, which is consistent with previous suggestions in the literature on the strong commitments and potential monitoring role of large foreign shareholders. Overall, our study highlights the importance of recognizing the heterogeneity among foreign investors and the benefits of large foreign shareholders to emerging stock markets.

Alternative Measures

This study examines the relevance of board independence to stock return volatility for a sample of 160 companies listed on the Vietnamese stock market over ten years (2008-2017). After controlling for potential endogeneity, we find that the presence of non-executive directors on the board tends to increase firm risk. The results indicate that non-executive directors do not play a supervisory role under the agency theory. Our findings remain robust when we apply alternative measures of the dependent variable.
