    Is there any justification for investing in managed mutual funds or are managed funds for suckers, as indexing advocates argue? We answer this question by looking at a long time span of real fund returns (26 years) for one specific company (Vanguard) that is notable for its low fees on managed funds. By creating synthetic portfolios— portfolios based on weighted averages of the assets of Vanguard’s mutual funds—we find that whether index funds or managed funds are the superior buy depends on the time span in question, but that managed funds almost always have a lower standard deviation of return than index funds.
