We describe the fundamental issues that long-horizon event studies face in choosing the proper research methodology, and summarize findings from existing simulation studies about the performance of commonly used methods. We document in detail how to implement a simulation study and report...

We examine stock trading activities in days before Chinese listed firms made public announcement to start share-structure reform. There is significant evidence that, relative to a benchmark period, institutional investors bought more event firms' shares in the last two trading days prior to...

This document is the Online Appendix to "Quality of PIN Estimates and the PIN-Return Relationship" by Yuxing Yan and Shaojun Zhang in Journal of Banking and Finance 43 (2014), pp 137-149. It includes two tables and four figures. The first table compares the two sets of quarterly PIN estimates...

We construct the five factors in Fama and French (FF, 2015) and the four factors in Hou, Xue, and Zhang (HXZ, 2015) for the Chinese stock market. Our objective is to identify a parsimonious factor model that builds on these factors and provides an adequate explanation for time-series and...

The Split Share Structure Reform in China offers a unique opportunity to test whether the supply of tradable shares (i.e. float) has a significant impact on the degree of speculation. After firms completed the reform, their float increased by 31% on average, while turnover and trading volume...

This paper provides new evidence concerning the probability of informed trading (PIN) and the PIN-return relationship. We take measures to overcome known estimation biases and improve the quality of quarterly PIN estimates. We use the average of a firm's PIN estimates in four consecutive...

We investigate whether and how information about one stock’s future volatility is transferred to other related stocks along the supply chain. The supply chain setting offers an ideal setting to study the effect of cross-firm volatility information transfer because customers and suppliers are...

This paper shows that the cross-sectional and time series momentum in currencies, which cannot be explained by carry and dollar factors, summarize the autocorrelation of these factors. These momentum strategies long currency factors following positive factor returns and short them following...

Recent studies find that transactions volume and volatility spread of exchange-traded single-stock options predict the underlying stock’s future returns. Most of the firms with exchange-traded options have large market capitalization and are actively traded. It is a puzzle why it takes days...

China is the largest emerging market and attracts a great deal of attention from investors and researchers worldwide. The Fama-French three-factor model is the outcome of decades of research on U.S. stock returns. To what extent the three factors explain the variation in Chinese stock returns is...
