Additional Factor in Asset Pricing: Institutional Ownership

Dr. Ecenur Uğurlu Yıldırım

Abstract

In this paper, we hypothesize that institutional investor variable might be a proxy for some systematic risk factors, such as asymmetric information risk, noise trader risk, or agency problem, which should be incorporated into the asset-pricing model. Our data encompasses 4320 firms listed on NYSE, NASDAQ and AMEX that are traded between January 1980 and December 2016. Mimicking portfolio for institutional ownership, called IMI (Institutional minus Individual), is constructed. Including IMI to the Carhart’s 4-factor model captures the common variations in returns better than all other models that are tested. Consistent with the literature, the new 5-factor model improves mispricing mostly in portfolios including stocks with the lowest and the highest institutional ownership. When we test the empirical relationship between IMI and possible risk factors it proxies, results suggest that IMI most likely proxies to asymmetric information risk.
