I study empirically how competition among high-frequency traders (HFTs) affects their trading behavior and market quality. The analysis exploits a unique dataset, which allows comparing environments with and without high-frequency competition, and contains an exogenous event - a tick size reform...

Do all types of information benefit the efficiency of prices in the sense that they drive them closer to fundamentals compared to the situation where information does not exist? Looking at the competitive noisy rational expectations framework, the clear answer of the literature is: yes. It...

Relying on the Stambaugh, Yu, and Yuan (2015) mispricing score and on 45 countries between 1994 and 2013, I document economically meaningful and statistically significant cross-sectional stock return predictability around the globe. In contrast to the widely held belief, mispricing associated...

From 2007 to June 2013, a small group of fee-paying, high-speed traders receive the Michigan Index of Consumer Sentiment (ICS) from Thomson Reuters at 9:54:58, two seconds before its broader release. Focusing on the trading and price behavior in E-mini S&P 500 futures, we find that this tiered...

This study investigates the characteristics of systematic internalizers (SIs) and the impact of SI operations on price efficiency, which refers to price informativeness about fundamental values. The results show that market making trading firms on exchanges are more likely to operate as SIs....

Purpose Based on the textual-analyzed data covering 2148 IPO firms in China's stock market during the 2007-2018 period, the authors' purpose is to examine the influence of anti-takeover provision (ATP) adoption on initial public offerings (IPO) underpricing and identify the reducing effect of...

This paper shows that, in the canonical dynamic rational expectations equilibrium model, public information about future noise trading is potentially detrimental to contemporaneous price efficiency. Our result supports concerns that social sentiment investing, sparked by growing availability of...

This research represents the union of two main studies: the first one focused on the analysis of the CAPE Ratio, also known as the Cyclically Adjusted Price-Earnings ratio, a valuation measure introduced by the Nobel Prize Robert Shiller, and the second one focused on the predictability of the...

It is commonly overlooked that the concept of market efficiency embowers a time-dimension. Illustrating with an example from the class of persistent random walks, we show that a price process can be a martingale on one time-scale but inefficient on another. This means that just as market...

This paper introduces a novel hypothesis in the context of share buybacks, proposing the existence of a "Free Lunch" phenomenon associated with the use of specific execution products. The hypothesis posits that these products can generate consistently positive fees, offering a consistent return...
