Evaluating fund capacity: issues and methods

Abstract

We examine the issues and methods involved in evaluating the size that an equity fund might attain before it becomes unable to create additional value for investors. We discuss how capacity is defined, identify ten drivers and outline methods for conducting capacity analysis. We detail models that predict capacity, assuming that a fund adjusts the manner in which it trades and constructs portfolios as funds under management grow. We also provide an overview of transaction cost modelling, which is integral to predicting capacity. This study is primarily intended as an aid for investment industry participants who wish to evaluate the capacity associated with a given investment signal.

“…Although there is no single definition of investment capacity, O'Neill and Warren [23] provide an excellent literature review about issues and methods for fund capacity evaluation. According to them, investment capacity has been defined and measured in three ways: threshold capacity, terminal capacity, and wealth-maximizing capacity.…”

Flow‐driven risk shifting of high‐performing funds

“…In contrast, high-performing funds resulting from luck would be prone to increase risk when experiencing high flow because of self-cognitive bias. To make things worse, large inflow may exceed the fund capacity, and damage the income of the fund (O'Neill and Warren, 2019). Furthermore, previous studies show that younger mutual funds and smaller funds have greater incentives to shift risk (Chevalier and Ellison, 1997;Huang et al, 2007).…”
