Using trade-level data, we study whether brokers play a role in spreading order flow information. We focus on large portfolio liquidations, which result in temporary drops in stock prices, and identify the brokers that intermediate these trades. We show that these brokers' best clients tend to...

The regulator plays an active role in the IPO process via its pre-IPO communications with firms, writing 3.8 comment letters per company. To evaluate the regulator's input, we analyze these communications between the SEC and firms using LDA-analysis and KL-divergence. Main topics of SEC concerns...

We show that wealth processes in the block-shaped order book model of Obizhaeva/Wang converge to their counterparts in the reduced-form model proposed by Almgren/Chriss, as the resilience of the order book tends to infinity. As an application of this limit theorem, we explain how to reduce...

We document a curious feature of the German mutual fund industry. Unlike U.S. mutual funds, funds domiciled in Germany do not necessarily compute their net asset values (NAV) as of market close. Using a sample of German equity funds, we infer each fund's NAV closing time from the best-fit market...

The paper proposes a novel direction to rationalize and quantify investors' flipping behavior and its effect on underpricing in IPOs through the use of a structural approach mode. The outcome is a proxy value that replicates investors' flipping behavior. When tested empirically, the model...

If regulation fails to differentiate between priced and idiosyncratic risk, it incentivizes investors to reach for yield. Studying securitization exposures on the balance sheets of German banks, I show evidence consistent with this prediction. Banks with tight regulatory constraints (low capital...

This paper examines short sales transaction volumes on the first trading day of 610 initial public offerings (IPOs) from 2011 to 2015. The tests provide evidence of informed trading immediately at the IPO. Results reveal that short selling volume on the first trading day of the IPO is...

Using a sample of S&P 500 firms between 2013 and 2017, we study the impact of ESG rating disagreement on stock returns. We conjecture that for disagreement about environmental ratings, a risk-based explanation induces a positive relationship between rating disagreement and stock returns. In...

Random changes in firms' stock index membership have important implications on sell-side analysts' career outcomes. Covered firms moving from the bottom of Russell 1000 to the top of Russell 2000 significantly increase an analyst's likelihood of moving to a high-status broker or receiving a...
