Investment performance studies of pension or mutual funds have overall been too statistically inconclusive to create definitive rankings to help investors make fund selection decisions. This paper presents an alternative approach based on comparing the pension or mutual fund firms themselves which are highly diversified composite portfolios aggregated over all individual portfolios managed by the firms. Performance data of managed fund firms are more useful for investors because we show here that their statistics are more stable and predictable than those of individual portfolios which are subject to more random influences such as selection bias.
This paper overcomes the pitfalls of the Sharpe ratio in ex-post performance ranking by using a new metric for the performance of the composite portfolio of a firm. The metric is risk-adjusted by the volatility of the firm’s benchmark, defined by the aggregate asset allocation of the firm. In an empirical study using unique data, we measure the performance of 115 major Australian superannuation firms. The results show that using the new metric the investment performance ranking of the firms is persistent. We identify that higher operational costs are correlated significantly with lower net investment performance. We indicate how the performance ranking of the firms can help investors make fund selection decisions.
