We show that immediate and delayed abnormal returns following earnings announcement surprises differ across market states. Immediate abnormal returns are more sensitive to earnings surprises in down markets, while delayed abnormal returns are less sensitive; underreaction is attenuated in down...

We construct a measure of individual investors' speculative demand for stocks from their online queries on penny stocks provided by Google Search volume index (hereafter "SVI"). We examine how it affects the return dynamics of U.S. stock indices. We find that the speculative demand leads to a...

We find that the stock market underreacts to stock level liquidity shocks: liquidity shocks are not only positively associated with contemporaneous returns, but they also predict future return continuations for up to six months. Long-short portfolios sorted on liquidity shocks generate...

This paper uses a novel approach to analyze the weather's effect on stock returns. In contrast to previous studies, I focus on barometric pressure to analyze whether there is a weather effect because only barometric pressure is physically experienced by all decision makers, be they indoors or...

We provide novel evidence supporting the view that stock prices of some firms in the early growth stage of their life cycle are set by optimistic investors fixated on sales growth. We identify these firms as those that went public during an industry IPO waves, had high sales growths but low...

Using hand-collected TV programming data and intra-day trading from China, we compare the trading, liquidity, and returns of on-show and off-show stocks in the same sector. Our difference-in-difference analysis reveals that post-show, off-show stocks experience significant improvements in...
