I was surprised to see an article @ the Vanguard website mentioning the advantages and out performance of their actively managed funds:
"Between 1985 and 2014, Vanguard active funds, on an asset-weighted basis, have delivered about 0.45% in outperformance, net of fees.1 That may seem insignificant, but a small return advantage compounded over 30 years, can amount to a meaningfully higher-ending portfolio value. In this instance, an initial $10,000 investment invested across Vanguard's active funds, on an asset-weighted basis, would have grown to more than $287,000 at the end of 2014. That's more than 60% above their stated benchmark return of about $175,500."
