Green human resource management (GHRM) and corporate social responsibility (CSR) have recently gained more attention in the business world. This study aims to investigate the role of corporate support for employee volunteering (CSEV) in strengthening the impact of GHRM on adopting CSR practices of the best 30 firms registered in EGX100 at the Egyptian stock exchange and engaged with CSR activities. Therefore, a conceptual framework was proposed to list theoretical concepts of GHRM, CSEV and CSR to form hypotheses. Data were collected from 326 respondents occupying the highest managerial positions in the studied firms. Using a structural equation model (SEM), the results indicate that both GHRM and CSEV influence positively on adopting CSR activities. Furthermore, CSEV plays a positive moderating role in strengthening the impact of GHRM on adopting CSR in the studied firms. These findings and their managerial implications were discussed in theory and practice.

Purpose: We examined whether investor sentiment affects the volatility of the Egyptian exchange. While examining this relationship, we also test whether stock market liquidity is the channel than can affect the relationship between investor sentiment and Egyptian exchange volatility.Methodology: This study adopted the positivism philosophy, quantative method, and deductive approach. In addition, we collect secondary data from the financial statements of the listed companies on the EGX 100 comprise the study's population. After excluding statements from banks and financial institutions and relying solely on the consolidated financial statement, the sample consists of 305 observations from 76 firms. The data was analyzed to verify if the time series is a stationary time series or not by using Dick-Fuller test and GARCH model. Then, we use the correlation matrix coefficient and descriptive statistics to describe the data. Finally, the research model was validated with structural equation modeling (SEM).Findings: Results of the study found a significant negative relationship between investor sentiment and stock market volatility. Besides, stock market liquidity partially mediates the relationship between investor sentiment and stock market volatility. Recommendations and Further Direction:Based on the results, this study presents recommendations that could help to improve the performance of the Egyptian exchange. Also, it offers some directions for future research.
