Research Topic

Interfirm Links, Return Predictability and Quantitative Strategies

Research Summary

A body of evidence has accumulated documenting interfirm return predictability. Scholars find the economically linked firms exist return predictability. Cohen and Frazzini (2008) introduce customers to supplier return predictability. Cohen and Lou (2012) find standalone firm's have a conglomerate return predictability due to complicated information processing. 

However, the financial link, as the other essential firm relationship, is rarely paid attention to by scholars. I study parents which have complex ownership structures. I propose a novel channel: the ownership links lead to return predictability via slower information incorporation.
