This paper examines how the extent of short-term trading relates to the efficiency of stock prices. We employ a new duration measure based on quarterly institutional investors' portfolio holdings, next to existing proxies such as trading volume, the percentage of transient institutions, and fund...

We examine how boards decide on CEO compensation depending on how informative stock prices are. In order to mitigate the endogeneity of board decisions, we use extreme mutual fund flow-driven trading pressure as an exogenous shock to stock price informativeness. Consistent with informed boards...

We examine whether boards are sufficiently well-informed to make efficient decisions on CEO compensation. In order to mitigate the endogeneity of board decision on CEO compensation, we use mutual fund flow-driven trading pressure as an exogenous shock to stock price informativeness. Consistent...

This paper studies the association between hedge fund activism and firm value, using matching procedures to mitigate the selection effects of which firms are chosen as targets by activist hedge funds. We find that targeted firms improve less in value (Q) subsequent to the start of activism than...

We document that stocks that have optimistic (pessimistic) consensus recommendations and are currently held by many short-term institutions exhibit large stock-return reversals: their large past outperformance (underperformance) is followed by large negative (positive) future alphas. The...
