We use transactions data from TORQ and present empirical evidence on the cross sectional relation between institutional trading and effective spread after controlling for trading volume denoting inventory and order processing costs and probability of informed trading (PIN) denoting risk of...

We investigate whether providers of high frequency news analytics affect the stock market. As identification, we exploit a unique experiment based on differences in news event classifications between different product releases of a major provider of news analytics. We document a causal effect of...

This paper employs a new and comprehensive data set to investigate short-term herding behavior of institutional investors. Using data of all transactions made by financial institutions in the German stock market, we show that herding behavior occurs on a daily basis. However, in contrast to...

Due to data limitations and the absence of testable, model-based predictions, theory and evidence on herd behavior are only loosely connected. This paper attempts to close this gap in the herding literature. From a theoretical perspective, we use numerical simulations of a herd model to derive...

This paper employs numerical simulations of the Park and Sabourian (2011) herd model to derive new theory-based predictions for how information risk and market stress influence aggregate herding intensity. We test these predictions empirically using a comprehensive data set of highfrequency and...

We examine the trading behavior of institutional investors during the internet bubble and crash of 1998–2001, and its impact on stock prices. Similar to some recent findings concerning the trading behavior of hedge funds and NASDAQ 100 stocks, we find that during the bubble all types of...

We examine the performance of buy-side institutional investor trades and sell-side brokerage analyst stock recommendations, as well as their interactions. Buy-side trades follow sell-side analyst recommendations but not the other way around. While buy-side purchases significantly outperform...

This paper provides new evidence on the causes and consequences of herding by institutional investors. Using a comprehensive database of every transaction made by financial institutions in the German stock market, we show that institutions exhibit herding behavior on a daily basis. Herding...

Share repurchase announcements with higher turnover ratio attract more attention from institutions than events with lower turnover ratio. The stock price behavior is associated with the institutional trading behavior around share repurchase announcements. The higher exposure to the attention...
