RT Journal Article SR Electronic T1 Data Envelopment Analysis of Morningstar's Small-Cap Mutual Funds JF The Journal of Investing FD Institutional Investor Journals SP 87 OP 92 DO 10.3905/joi.2006.616858 VO 15 IS 1 A1 John A. Haslem A1 Carl A. Scheraga YR 2006 UL https://pm-research.com/content/15/1/87.abstract AB Data Envelopment Analysis (DEA) is applied to the Morningstar 500's small-cap mutual funds to identify those that are efficient or inefficient in a production theory sense. That is, this study examines the efficiency of mutual fund portfolio management, rather than the typical analysis of fund performance. In addition, the descriptive variables—investment style attributes—that differ significantly between efficient and inefficient funds are identified, and the nature of these relationships examined. This study follows Haslem and Scheraga (2003) that applied DEA to Morningstar's large-cap funds.TOPICS: Mutual funds/passive investing/indexing, mutual fund performance
