That’s why I wrote If You Can’t Beat ‘Em – Join ‘Em: Investing in Low Cost Index Funds. The basic gist of the matter is that index funds, which can mirror any one of the major stock market indices, have a far lower cost structure than traditional portfolios; a typical index fund, for example, might charge 0.15% versus 1.25% for a regular, run-of-the-mill mutual fund. In addition, the index only sells stocks when they are dropped as a result of mergers, de-listing, or admitting a better company. This results in lower turnover, which was one of our earlier secrets to beating the market.
In short, if you are looking for a no-brain way to own America, Inc., an index fund is probably the way to go.
