“…Although a more (less) mood-congruent regulatory policy can lead a new industry to appear less (more) risky and, hence can promote or inhibit herding (as discussed previously), this may not be uniform across the universe of that industry's stocks, which are expected to vary in riskiness-terms. Herding, for example, has been found (Lakonishok et al, 1992;Wermers, 1999;Sias, 2004;Dang and Lin, 2016;Cui et al, 2019) to maintain an inverse relationship with size (appearing the strongest for smaller capitalization stocks) due to the high information risk of small stocks prompting investors to monitor their peers' actions when trading them. Additionally, sectors with greater uncertainty (in terms, e.g., of their cash flows) may be more prone to exhibiting herding, as evidence from Technology stocks has suggested in several studies (Brunnermeier and Nagel, 2004;Griffin et al, 2011;Singh, 2013;Gavriilidis et al, 2013;Andrikopoulos et al, 2017;Uwilingiye et al, 2019).…”
