We measure net arbitrage trading by the difference between abnormal hedge fund equity holdings and abnormal short interest on a stock. In the cross section, net arbitrage trading strongly predicts future stock returns. This predictability is not due to temporary price pressure, cannot be produced using total institutional holdings, but is consistent with information advantage and copycat tradin...

A 65-year-old man suffering from esophageal cancer presented with postoperative alcohol withdrawal syndrome. Diazepam was used intravenously, but his condition did not improve. With inhalation of alcohol vapor driven by oxygen, the abnormal symptoms subsided and vital signs began to return to normal rapidly.

We examine the impact of firm ownership composition on both the abnormal returns at the announcement of a stock split and liquidity changes following a stock split. We find three results. First, the largest post-split increase in institutional ownership occurs for firms that had low institutional ownership prior to the split. Second, changes in liquidity are negatively related to the level of i...

Running rails used as a return conductor and ungrounded scheme have been widely adopted in DC traction power systems. Due to the longitudinal resistance of running rails and insulation resistance of rail-to-ground, there will be a potential rise between running rails and the ground when return current flows through the running rails, which is known as rail potential. At present, abnormal rise o...

A commonly used approach in long-run event-studies is the calendar time portfolio (CTP) approach developed by Jaffe (1974) and Mandelker (1974) and advocated by Fama (1998). For each calendar month we compute the return of an equally-weighted portfolio of companies that unionized in the last T months, where T is either 18 or 24 in our study. The return of this “unionization portfolio” is denote...

In this paper we examine the market reaction—price and volume—to the appearance of a firm in the Who’s News column of The Wall Street Journal. We differentiate between those firms whose articles are accompanied by a picture of an executive and a control set of firms whose articles on the same day are not accompanied by a picture. The results show a more pronounced market reaction to the “cum pi...
