The first subset of papers in this special issue on the effects of the pandemic on the stock market, because they use more recent data than previous studies (see Phan and Narayan 2020; Sharma and Sha 2020, 2021; Sha and Sharma 2020 and Yang and Deng 2021) merely provide a robustness test to earlier hypotheses tests. This is welcomed because one limitation of the earlier studies on COVID-19 has been the lack of data (see Narayan 2021). One direction for future studies that remains is to evaluate more the industry or sectoral links to the pandemic and understand the dynamic effects, effects on value chains, understanding supply chain bottlenecks and constraints in terms of human resources and digitalization aspects of industrial growth during the pandemic. None of these issues have been explored in-depth and there is scope for new research on these business and economic aspects.

The second subset of studies published in this issue relating to the commodities market deserves more works along the following lines. First, the co-existence of the pandemic with falling oil prices initially and then a significant growth in oil prices with the on-set of geopolitical tensions marks an interesting platform on which to study the three-way relationship between the financial system, and geopolitical tensions (trade wars included) and oil prices. Theoretical models that identify the role of trade wars in economic growth and corporate growth/performance will be needed to enhance research in this area. In this regard, the story of oil price and the pandemic has already been discussed in Devpura (2020), Devpura and Narayan (2020), Prabheesh et al. (2020), and Wang and Su (2021).

The third group of studies occupying this special issue motivates several lines of additional research. First, the issue of news sentiment is important from behavioral finance and economic points of view in understanding the effects of the pandemic on the financial and economic system. This stands out to be an area that deserves greater research attention. Fittingly, new news-based datasets have been developed, such as the one by Narayan et al. (2021). This dataset has news on several variants of the pandemic and would therefore be useful in studying the effects of the pandemic (from a heterogeneous perspective) on the financial and economic systems. Some studies have already analyzed the role of news during the pandemic; see Hoang and Syed (2021) and Salisu and Akanni (2020).

Second, more studies are needed to evaluate the effects of specific events resulting from the pandemic on the financial economic systems. This will allow us to understand the relevance of policies in mitigating the effects of the pandemic. Some of the events about whose effectiveness we still do not fully understand are the (a) roles of specific fiscal and monetary policies; (b) geographic lockdown effects; and (c) digital trade. For some preliminary studies, see Phan and Narayan (2020), and Yang and Deng (2021).

Third, there is limited work on COVID-19 related portfolio diversification as conducted in this special issue by Narayan et al. and portfolio-based investments such as Prabheesh (2020). This deserves more research to understand the relevance and effectiveness of different trading strategies during the pandemic across a wide range of assets.
