You can barely hear the quiet hum of money being invested — money in scarcely imaginable quantities, pouring into low-cost index mutual funds
and exchange-traded funds (E. T.F.s) that track financial markets.
“Since the crisis, investors have been saying, ‘I may not be able to control the market,
but I can control how much I pay in mutual fund expenses.’ And when they look for quality funds with low fees, the first answer is Vanguard.”
See how the largest, leading and lagging funds compare.
The triumph of index fund investing means Vanguard’s traders funnel as much as $2 billion a day into stocks like Apple, Microsoft
and Amazon, as well as thousands of smaller companies that the firm’s fleet of funds track.
It is manageable, in large part, because no stock-picking is involved: The money simply flows into index funds
and E. T.F.s, and through February of this year, nine out of every 10 dollars invested in a United States mutual fund or E. T.F.
