FYI: Vanguard recently published a short paper called “MYTH: Active management performs better in certain market segments.” Taken literally, that claim is untrue. Over any time period, some categories of active funds fare better than others. Thus, per Morningstar’s Active/Passive Barometer research, three times as many actively run emerging-markets stock funds beat their benchmarks over the trailing 10 years as did active large-blend U.S. stock funds.
