Mutual fund performance: The decision quality and capital magnet efficiencies. Managerial and Decision Economics 41(5), 861– 872. https://doi.org/10.1002/mde.314301436570https://doi.org/10.1002/mde.3143http://hdl.handle.net/20.500.12519/221This study employs a two-stage network data envelopment analysis model to analyze the decision quality and capital magnet efficiencies of 155 mutual funds in Taiwan during the period 2007–2016. The empirical results show that fund managers improved their decision quality; however, their capital magnet efficiency declined. This study also found 10 mutual funds performing in decision quality and capital magnet efficiencies, from which practical suggestions are provided to investors. Finally, this study constructs a market competition matrix to help fund managers (and investors) improve their operating and portfolio performance, plus resource allocation. © 2020 John Wiley & Sons, Ltd.enLicense to reuse the abstract has been secured from John Wiley and Sons and Copyright Clearance Center.Mutual fundsFundsFund returnsArticleCopyright : © 2020 John Wiley & Sons, Ltd.
