Biography

My research interests are in the area of corporate finance and institutional investors. I study how non-fundamental liquidity shocks deriving from natural disasters affect corporate policies through the channel of mutual fund flows. In another work, we analyze how the interplay between institutional investors with different signals affects market efficiency.

Strategic trading as a response to short sellers

Journal of financial markets, 69 Doi: 10.1016/j.finmar.2024.100911

We examine whether the strategic response to short selling by other informed investors decelerates the incorporation of positive information. We find a sizeable reduction of positive information impounding before earnings announcements for stocks more exposed to short selling. Consistent with strategic behavior, we find that investors with positive views slow down their trades when short sellers are also present. Furthermore, they break up their buy trades across multiple brokers, suggesting they wish to prevent a price impact. Thus, the strategic reaction to short selling appears to have implications for information impounding before public information releases.
