Scale diseconomies and capacity in fund management: variation across equity markets
Year: 2024
Type: article
Abstract: Purpose We model the relation between excess returns, fund size and industry size for active equity funds. Design/methodology/approach We study and contrast four markets – global equities, emerging markets, Australia core and Australia small caps – and use the results to investigate the extent to which funds deviate from estimated capacity. Findings We uncover a significantly negative relation between returns and both fund size and industry size across all markets. The estimated percentage of funds operating above versus below capacity varies both across markets and over time, as does the role played by fund size versus industry size. We find a greater prevalence of funds operating significantly below than above capacity, in contrast to findings for US equity mutual funds. Significant deviations from estimated capacity persist for a median of between two and six quarters. Originality/value Our main contribution is to show that the dynamics governing deviations from capacity for active equity funds vary across markets.
