RT Journal Article SR Electronic T1 Enhanced versus Passive Mutual Fund Indexing: Has DFA Outperformed Vanguard by Enough to Justify Its Advisor and Transaction Fees? JF The Journal of Investing FD Institutional Investor Journals SP 71 OP 81 DO 10.3905/JOI.2008.17.4.071 VO 17 IS 4 A1 Tower, Edward A1 Yang, Cheng-Ying YR 2008 UL http://joi.pm-research.com/content/17/4/71.abstract AB Passive and enhanced index funds are two important options for investors. Vanguard is the largest provider of passive indexed funds, and DFA is one of the major providers of enhanced indexed funds, with uniquely close ties to academic financial research and an illustrious board of directors. Vanguard has low fees and investors can buy Vanguard funds directly. DFA’s fees are higher and one can invest in DFA funds only through an advisor, who charges for the service. Moreover, one must pay transaction fees to a custodian. We ask whether DFA has outperformed Vanguard by enough to justify the additional fees.
