Abstract
This study examines whether the current virus pandemic (COVID-19) has any significant negative effect on returns series of selected stock markets in the developed, Asian and GCC countries. For this purpose, the EGARCH (1, 1) model and the News Impact Curve (NIC) are applied to examine the persistence of symmetric volatility, leverage-effect and inducing volatility by preceding bad or good news. The findings suggest that the volatility is persistent in all stock markets, but it is under unity for many stock markets, which means the volatility will persist for the short term in most cases. Furthermore, the findings of asymmetric volatility analysis indicate the presence of leverage-effect over the study period in all the selected stock markets except Japan, Indonesia and Hong Kong. However, NIC plots provide evidence that the negative shock (news) of the COVID-19 outbreak would put forward a higher volatility on all selected stock market returns in the near future, except for the stock markets in Thailand, Japan and Singapore, where the shocks (positive) suggest a higher subsequent period of conditional variance compared to the current shocks (negative) of the COVID-19 pandemic. Consequently, understanding the volatility structure of stock market returns is imperative for policy guidance among the policymakers and potential investors. For policymakers, as the volatility caused by the COVID-19 outbreak is persistent for the short term, this may encourage governments and central banks to implement effective measures to stimulate fiscal and monetary policies to counter the distraction caused by the pandemic, support the economic activities and cushion the local firms from the pandemic effect. For investors, the findings suggest that long-term investment decision should be taken to invest in all stock markets that are negatively affected by the COVID-19 outbreak to achieve capital gain in the future, while short-term investment decisions may be undertaken to take advantage from the short-term market volatility.

Abstract
The present chapter tries to assess the state of art of enterprise risk management (ERM) among Portuguese non-financial companies regarding two main aspects: the ERM background in Portugal and the level of disclosure of ERM practices by non-financial listed companies. Since the analysis of disclosures is useful to understand the level of evolution and adoption of ERM framework we tried to assess the ERM practices disclosed by 26 Portuguese non-financial listed companies at the Euronext Lisbon Stock Exchange regulated market, during the period of 2006–2016. Main findings indicate that regulation on ERM in Portugal emanates from three main Codes (The Portuguese Companies Code, The Stock Exchange Code, and The Corporate Governance Code). The ERM professionalization in Portugal is its infancy and has been promoted mainly by the Institute of Portuguese Internal Auditors. Moreover, research on topics such as risk reporting and risk management/ERM is very scarce. Overall, findings of prior literature are consistent with results from our exploratory study. We conclude that Portuguese non-financial listed companies still disclose very little information on ERM activities. However, over the period of analysis, the disclosure practices evolved positively. Findings show that ERM disclosure can still be extensively improved in the future.
