Why Do Short Sellers Like Qualitative News?
Short sellers trade more on days with qualitative news--i.e. news containing fewer numbers. We show that this behavior is not informationally motivated but can be explained by short sellers exploiting higher liquidity on such days. We document that liquidity and noise trading increase in the presence of qualitative news thus enabling short sellers to better disguise their informed trades. Natural experiments support our findings. For example, qualitative news has a bigger effect on short sellers' trading after a decrease in liquidity following a stock's deletion from S&P 500 and a lower ...

Biased Shorts: Short sellers’ Disposition Effect and Limits to Arbitrage
We investigate whether short sellers are subject to the disposition effect using a novel dataset that allows to identify the closing of short positions.

A trading strategy based on this finding achieves significant three-factor alphas. Overall, short sellers? behavioral biases limit their ability to arbitrage away the ...

First to \"Read\" the News: New Analytics and Algorithmic Trading
Exploiting a unique identification strategy based on inaccurate news analytics, we document a causal effect of news analytics on the market irrespective of the informational content of the news.

Inaccurate news analytics lead to small price distortions that are corrected quickly. The market impact of news analytics is greatest for press releases, which are timelier and easier to interpret algorithmically. Furthermore, we provide evidence that high frequency traders rely on the ...
