We investigate the impact of COVID-19 on Chinese stock market by an event study and examine the effect of individual investor sentiment on returns. The pandemic has an overall negative effect on stock market during the post-event window, which can't be explained by real losses. Results show a stronger positive correlation between individual investor sentiment and stock returns than usual. The impact on individual investor sentiment on stock returns is more significant for enterprises with high PB, PE and CMV, low net asset, and low institutional shareholding. Only 7 industries related to pharmacy, digitalization, and agriculture are boosted.

Marketed endothelin receptor antagonists (ERAs) have been associated with testicular tubular atrophy and decreases in male animal fertility in chronic toxicity studies in rats and dogs. Consistent with these findings, reduced sperm count has been observed in the clinical setting and is considered a potential class risk with chronic administration of ERAs. In contrast, no such effects on male animal fertility are noted with angiotensin II type 1 receptor blocker (ARB) treatment.

Fast growth rate and stocking density are global animal welfare concerns for broiler chickens. The objective of this study was to evaluate the effect of genetic strain and stocking density on the behavior of broilers. In a 2 × 2 randomized complete block design, conventional (CONV) and slow-growing (SG) broilers were stocked at either 29 kg/m (LO, n = 31 birds/pen) or 37 kg/m (HI, n = 40 birds/pen) in 16 pens (n = 4 pens/treatment).

Increasing awareness of climate change and its potential consequences on financial markets has led to interest in the impact of climate risk on stock returns and portfolio composition, but few studies have focused on perceived climate risk pricing. This study is the first to introduce perceived climate risk as an additional factor in asset pricing models. The perceived climate risk is measured based on the climate change sentiment of the Twitter dataset with 16 million unique tweets in the years 2010-2019.
