Sell-Side School Ties

by Lauren H. Cohen, Christopher J. Malloy and Andrea Frazzini

Abstract

We study the impact of social networks on agents' ability to gather superior information about firms. Exploiting novel data on the educational backgrounds of sell-side equity analysts and senior officers of firms, we test the hypothesis that analysts' school ties to senior officers impart comparative information advantages in the production of analyst research. We find evidence that analysts outperform on their stock recommendations when they have an educational link to the company. A simple portfolio strategy of going long the buy recommendations with school ties and going short buy recommendations without ties earns returns of 6.60% per year. We test whether Regulation FD, targeted at impeding selective disclosure, constrained the use of direct access to senior management. We find a large effect: pre-Reg FD the return premium from school ties was 9.36% per year, while post-Reg FD the return premium was nearly zero and insignificant. In contrast, in an environment that did not change selective disclosure regulation (the U.K.), the analyst school-tie premium has remained large and significant over the entire sample period.

Lazy Prices

We explore the implications of a subtle "default" choice that firms make in their regular reporting practices, namely that firms typically repeat what they most recently reported. Using the complete history of regular quarterly and annual filings by U.S. corporations from 1995 to 2014, we show that when firms make an active change in their reporting practices, this conveys an important signal about the firm. Changes to the language and construction of financial reports have strong implications for firms' future returns: a portfolio that shorts "changers" and buys "non-changers" earns up to 188 basis points per month (over 22% per year) in abnormal returns in the future. These reporting changes are concentrated in the management discussion (MD&A) section. Changes in language referring to the executive (CEO and CFO) team, or regarding litigation, are especially informative for future returns.

Three years ago, Alvin Ang and his partner founded fidentiaX in Singapore, with the ambition to create the world’s first marketplace for tradable insurance policies on blockchain. With a 26-page white paper, the start-up closed a successful fundraising round through an initial coin offering (ICO). Three years later, however, the company still had not completed the infrastructure for the insurance trading platform. Besides the rapidly dwindling funds, fidentiaX had to fight with a tardy development team, uncooperative incumbent insurers, and begrudging investors. The case provides an overview of the blockchain industry and insights into the secondary life insurance market. Through the case, students will assess the company’s business strategies and learn about typical challenges faced by technology start-ups.
