Template-Type: ReDIF-Paper 1.0 Title: The Causal Effect of Institutional Ownership on Firm Level Risk Characteristics Author-Name: Farid Radmehr Author-Name: Tolga Cenesizoglu Creation-date: 2019 Abstract: We establish the causal effect of institutional ownership on a firm’s total risk and its systematic and idiosyncratic components using Russell 2000 index membership as an instrument for institutional ownership following (Crane, Michenaud, and Weston, 2016). We find that for a median Russell 1000 firm, a one standard deviation increase in institutional ownership in a given quarter causes a decrease in idiosyncratic volatility of 13.3% in annualized terms, which results in a decrease in total volatility of 12.8%. Institutional investors achieve this effect on a firm’s risk characteristics partially through their effect on its financial performance, as measured by unexpected earnings. More precisely, an increase in institutional ownership increases a firm’s financial performance, which turns to a decrease in its total and idiosyncratic volatility.
