We examine whether institutional ownership composition is related to parameters of the market reaction to negative earnings announcements. When firms report earnings below analysts' expectations, the stock price response is more negative for firms with higher levels of ownership by momentum or aggressive growth investors. There is no evidence, however, that these institutions cause an “overreaction” to earnings news. Ownership structure is also related to trading volume and to stock price volatility on days around earnings announcements. Our findings are consistent with the idea that the composition of institutional shareholders effects stock price behavior around the release of corporate information.

We examine how leveraged buyouts from the most recent wave of public to private transactions created value. Buyouts completed between 1990 and 2006 are more conservatively priced and less levered than their predecessors from the 1980s. For deals with post‐buyout data available, median market‐ and risk‐adjusted returns to pre‐ (post‐) buyout capital invested are 72.5% (40.9%). In contrast, gains in operating performance are either comparable to or slightly exceed those observed for benchmark firms. Increases in industry valuation multiples and realized tax benefits from increasing leverage, while private, are each economically as important as operating gains in explaining realized returns.
