“…Having scrutinized data from several major equity markets (Australia, Canada, Germany, Japan, Sweden, Taiwan, UK and the United States), Cao and Wei (2005a) find evidence that supports their theoretical conjectures: when the temperature is high (low), apathy dominates aggression (aggression dominates apathy); this, in turn, impedes (increases) risk-taking and results in lower (higher) stock returns. Other studies demonstrate a similar pattern within numerous developed and emerging stock markets around the world (Cao & Wei, 2005b;Chang et al, 2006;He & Ma, 2021;Hou et al, 2019;Sheikh et al, 2017;Yoon & Kang, 2009). Although several controversies emerged with concerns about the behavioral mechanism behind this phenomenon (see, e.g., Jacobsen & Marquering, 2008Kamstra et al, 2009), the overall conclusion appears unequivocal: A higher temperature coincides with lower stock returns (and vice versa).…”
