Proceedings of 7th Global Business and Social Science Research Conference 13 - 14 June, 2013, Radisson Blu Hotel, Beijing, China, ISBN: 978-1-922069-26-9 The Determinants of Investment Flows: Retail versus Institutional Mutual Funds Galla Salganik This paper compares the fund selection criteria used by investors in retail mutual funds with the criteria of investors in institutional mutual funds. I find that, compared with investors of retail mutual funds, clients of institutional mutual funds use more quantitatively sophisticated criteria such as risk-adjusted return measures and tracking error, demonstrate stronger momentum-driven and herding behaviors, and are less sensitive to fund expense ratio. In addition, I provide evidence that the previously-documented convex form of the flow-performance relationship is driven mostly by retail funds.
