摘要

先前的文献表明，投资者对彩票类股票的需求取决于许多因素，并且这些股票在长期内与非彩票类股票相比表现不佳。我们证明投资者对彩票类股票的需求取决于信息溢出的天数。具体而言，在宏观经济新闻日，对彩票类股票的需求取决于信息内容，其价格更密切地跟随市场指数的走势。这种波动倾向于在FOMC公告日和没有重叠收益公告的公司持续存在。我们提供了一个基于信息的理论来解释经验模式。

Conditional demand for lottery-type stocks: Information spillovers and asset prices comovement

Previous literature has shown that investors’ demand for lottery-type stocks is conditional on a number of factors, and that these stocks underperform in the long run compared to non-lottery-type stocks. We document that investors’ demand for lottery-type stocks is conditional on days with information spillovers. Specifically, on macroeconomic news days, the demand for lottery-type stocks depends on information content, and their prices more closely follow the market index movements. This comovement tends to persist on FOMC announcement days and for firms without overlapping earnings announcements. We provide an information-based theory to explain the empirical pattern.
