Some studies find that the markets linked to the investment in sustainable products exhibit better behavior (whether in terms of returns, risk, volatility or hedging effectiveness) compared to conventional markets during the specific COVID-19 pandemic period examined (e.g., Broadstock et al, 2021 ; Yi et al, 2021 ), while others report either underperformance of the former type of markets (e.g., Cui, Suleman, & Zhang, 2022 ; Dutta, Bouri, & Noor, 2021 ; Folger-Laronde et al, 2022 ), do not find significant differences (e.g., Capelle-Blancard, Desroziers, & Zerbib, 2021 ; Chiappini, Vento, & De Palma, 2021 ; Demers et al, 2021 ; Pavlova & de Boyrie, 2022 ), or even note contradictory results (e.g., Gianfrate, Kievid, & van Dijk, 2021 ; Hacıömeroğlu, Danışoğlu, & Güner, 2022 ; Omura, Roca & Nakai, 2021 ; Umar & Gubareva, 2021 ; Umar et al, 2021 ).…”
