How COVID-19 impacts Vietnam’s banking stocks: An event study method

Working capital management is germane for the success of the banking industry in Nigeria, especially the current state of the sector, which is engulfed with the effect of the global decline in oil price that has resulted in non-performing loans, deterioration of the bank asset quality, laying-off of staff amongst others. This is one of the reasons why the profitability of the banking sector deeply depends on the efficient management of a bank’s working capital. Therefore, the objective of this study is to examine how profitability of banks can be enhanced through the working capital management. To empirically carry out the analysis, panel data which consist of ten (10) deposit money banks in Nigeria for seven years (2010–2016) employing the panel fixed effect, panel random effect and the pooled OLS for the two models, which were used as proxies for bank profitability, which includes return on asset (ROA) and return on equity (ROE) to examine the best measure for bank profitability, with the indicators of working capital; net interest income, current ratio, profit after tax, and monetary policy rate. Results of the study showed that working capital management has a significant effect on the profitability of the selected banks and that return on asset is a better measure for bank profitability. Therefore, the study recommends that there should be a periodic review of the minimum capital base of the Nigerian deposit money banks so as to mitigate the effects of inflation and inculcate the consequence of time value of money, because the purchasing power of one (₦1) naira or one ($1) dollar today would not be sufficient to purchase what it can purchase today for tomorrow.

The current research aims to explore the impact of corporate governance on the Saudi banking performance for the period of 2014–2017. Though many researchers tested the relationship of corporate governance and firm performance, globally as well as in Saudi Arabia, however, during the literature review, it was found that many excluded the banking industry. This study tries to fill the gap by looking exclusively at the Saudi banking industry. Firm performance is measured through return on assets, return on equity, and Tobin’s Q as the dependent variables. The corporate governance practices are measured through the board characteristics (size, meeting, number of committees, independence, foreign board membership), and an audit committee (size, meeting, independence) as the independent variables. Firm size and firm age are the controls. Panel data analysis was implemented, using both descriptive and multivariate analysis through multiple regression to investigate the governance practices and firm performance. The empirical findings demonstrate that board size, audit committee meeting and bank size have a positive impact on ROE, whereas board independence has a negative impact on ROE. Similarly, board size and bank size have a positive relationship with ROA and board meeting has a negative relationship with ROA. Further, board (size and independence) and bank size have a positive relationship with Tobin’s Q, whereas number of board committees and bank age have a negative relationship with Tobin’s Q. Finally, audit committee (size and independence) and foreign board membership have no impact on the bank performance.

This study examined the response of stock prices on the Indonesia Stock Exchange (IDX) to COVID-19 using an event study approach and the GARCH model. The research sample is the closing price of the Composite Stock Price Index (JCI) and companies that are members of LQ-45 in the 40-day period before the COVID-19 incident, 1 day during the COVID-19 incident (March 2, 2020) and 10 days after, January 6, 2020 – March 16, 2020. Empirical findings prove that abnormal returns react negatively to COVID-19, JCI volatility fluctuates widely during the COVID-19 event, and the GARCH(1,2) model can be used to assess volatility and predict stock abnormal returns in IDX in market conditions infected with COVID-19. The practical implication of the study’s findings for investors is that the COVID-19 event caused stock price volatility, which affects abnormal returns. Therefore, to face the conditions of uncertainty and increased volatility in the future, several lines of risk management are needed in managing a stock portfolio. In addition, it also opens up opportunities for speculators to profit in an inefficient market environment. This study is based on the empirical literature currently being developed to investigate the phenomenon of stock price volatility behavior during COVID-19 on the IDX. The GARCH model used proves that during the COVID-19 pandemic, stock price volatility increases and leads to a decrease in abnormal returns. The empirical findings also validate the efficient market hypothesis theory related to the study of events and the theory of financial behavior related to uncertainty.
