The Gospel according to VANGUARD.

The article highlights the success of the Vanguard Group fund. Sometime, probably in 2003, Fidelity Investments will cease to be the largest fund purveyor in the world. Vanguard Group Inc. will take its place. Vanguard has $442 billion under management now, to Fidelity's nearly $700 billion. But the gap is closing. Last year Fidelity expanded its fund assets by roughly 20%, reflecting mostly the bull market. Vanguard grew by 33%--half from new money. Vanguard Group does buy a few ads to get people to ask for prospectuses. INSET: Thinking the unthinkable.
