Mutual fund investors are taking a broader view of the market when it comes to buying index funds.
Vanguard Group, the leading U.S. manager of index mutual funds, said Wednesday that a rising percentage of new investments is going to funds that track the Wilshire 5,000 index rather than the Standard & Poor's 500.
The Wilshire is the broadest U.S. index, covering about 7,400 stocks, while the S&P; represents 500 of America's biggest companies.
The Wilshire 5,000 has risen 11.6% so far this year, compared with a 12.1% rise in the S&P; 500 and a 19.8% rise in the Dow Jones industrial average.
But the assets of the Vanguard Total Stock Market fund surged almost 40% to $13 billion in the first half, the company said. Assets of the Vanguard 500 Index fund climbed 25% to $92.7 billion.
