摘要(英文):This paper shows that shifts in social sentiment affect stock prices. We use the Internet search volume on corporate social responsibility to capture investors’social sentiment shifts. Stocks with higher return sensitivity to social sentiment attract higher institutional demand and earn positive abnormal returns. A trading strategy that exploits the demand-based return predictability generates risk-adjusted returns of 1.2% per month. Our findings are consistent with stock prices underreacting to social sentiment shifts.
