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...

U.S. common stocks are simultaneously traded on multiple trading centers. We study quotes and trades with millisecond timestamps during the flash crash of May 6, 2010 and document new findings about order dynamics when the fragmented market is under stress. First, relative to May 5, 2010, the...

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...
