Index funds give investors a simple way to make money in the financial markets. I've recommended them for more than a decade, and I'm not alone.
According to Warren Buffett, "By periodically investing in an index fund … the know-nothing investor can actually out-perform most investment professionals." Buffett has stressed that basic investors who aren't savvy about stocks should just invest regularly in a large number of stocks over a period of time.
He's even put his money where his mouth is, betting a $1 million donation to charity that the Vanguard S&P 500 Index (VFINX) fund will outperform a handful of respected hedge funds over the coming decade.

But hold on ...
A key idea behind owning index funds is that you get to invest widely in one fell swoop. But there are limitations to the S&P 500. It contains most of the biggest American companies, yes, but it excludes thousands of smaller ones, which can outperform large caps. So if you really want to capture the whole U.S. market, you might want to opt for a total market index fund, such as the Vanguard Total Stock Market Index (VTSMX) fund, which will incorporate stocks like Visa
Then again, even the total stock market index still excludes foreign companies -- and ours is not the world's fastest-growing economy. By investing globally, we can profit as second- and third-world economies move up the ladder. Thus, you might also want to look at global index funds such as the Vanguard Total World Stock Index (VTWSX) fund. It includes thousands of big foreign companies such as BP
Building a strong portfolio doesn't have to be hard. If you pick wisely, you can do it with just a few index funds.
