After constructing high-frequency measures of informed trading as well as the measure of brand innovation proxied by the number of trademark registrations (TMRs), we first examine how market participants respond to the news about TMRs. The results show that the information on TMRs predicts...

In this study, we employ order imbalance measures to provide evidence that there exists an individual/institutional dichotomy in reactions to seasoned equity offerings (SEOs). The evidence supports the notion that small, possibly naıve, individual investors keep trading SEO stocks...

Using intradaily order flows processed via the Lee and Ready (1991) algorithm for NYSE/AMEX-listed stocks over the past 27 years, I estimate a set of price-impact parameters. The results provide strong evidence that price impact is priced in the cross-section of stock returns, even after...

How does an idiosyncratic shock to the liquidity of a stock affect the liquidity and prices of related stocks? Utilizing the feature that the second stage of a two-step spinoff increases the float of an already-public firm, we document strong evidence that the enhanced liquidity of spun-off...

We propose a unified set of distance-based performance metrics that address the power and extreme-error problems inherent in traditional measures for asset-pricing tests. From a Bayesian perspective, the distance metrics coherently incorporate both pricing errors and their standard errors....

We show that the noninformation component of trading costs is priced in the cross-section of stock returns using intraday data for NYSE/AMEX stocks. More importantly, we show that the noninformation component is much larger and more strongly related to stock returns than is the adverse-selection...

We develop a model to analyze the effects of hedging activities by options market makers (OMMs) facing informed trading. The model suggests that OMMs' hedging activities motivated by the adverse-selection risk lead to wider spreads in both stock and options markets. The hedging effect on spreads...

We study informed trading around announcements of merger bids (M&AD) and quarterly earnings (EAD). Extending the EKOP (1996) approach, we compute the daily posterior probabilities of informed trading on good and bad news. We find evidence of informed trading before and after M&AD and EAD. A...

In this study, we employ order imbalance measures to provide evidence that there exists an individual/institutional dichotomy in reactions to seasoned equity offerings (SEOs). The normally positive relation between imbalances and returns disappears for trade number imbalances but remains intact...
