What is an Index Fund?
Quite
simply, instead of investing in a few select stocks, an index fund invests
across the board in a particular index, such as the Wilshire 5000, NASDAQ
or S&P 500. The amount of money invested in any one stock is determined by
its market capitalization (or market cap) and the market cap of the other
companies in the index.
In contrast, a managed mutual fund
attempts to choose companies whose stock prices will rise, and get rid of
companies whose stock prices will fall.
Yet
statistics indicate that no mutual fund manager or brokerage can
consistently outperform--or "beat"--the market. What's more, experts have
scrutinized years of market data only to conclude that, on average,
brokerage and managed mutual fund returns have consistently fallen short
of the market, after their administrative expenses are factored in.
The Nobel Prize-winning theory behind
index funds--backed by countless years of experience and effort by
investors--shows the following: consistently achieving the level of
returns that the market achieves will yield greater returns than managed
mutual funds and brokerages will yield, over the long run.
The best way to achieve the market's
level of returns is to invest in index funds while simultaneously
controlling your investment expenses. No single index represents the
entire market, so it is necessary to invest in several index funds using
the appropriate
asset allocation.
