Indexing a Smarter Way

Costs matter. That sums up the simple case for index funds.

— John C. Bogle, "Index Mutual Funds: Profiting from an Investment Revolution"

What exactly is indexing?

You may have heard that indexing is a smart way to invest for your future. But what does 'indexing' mean, exactly?

Indexing, or index investing, is the practice of buying into index-based funds that track the investment returns of a specified stock or bond benchmark index such as the S&P 500 or the Russell 2000.

Index Examples
S&P 500 500 widely-held stocks thought to be representative of the U.S. stock market as a whole
Russell 2000 the 3000 largest companies (by value) in the U.S. market, minus the 1000 largest


How index funds are different

A traditional mutual fund is actively managed: that is, the investment company employs one or more persons to conduct extensive research and make frequent stock trades in an attempt to garner returns for their investors. To measure the fund's success, it's often compared to a peer index.

Index-based funds, by contrast, are passively managed: they hold a portfolio of stocks or bonds selected to mirror the makeup and performance of a particular index. Portfolio decisions are automatic based on the holdings of the benchmark, and trading of securities is typically infrequent.

Index funds come in two flavors: index mutual funds and exchange-traded funds (ETFs). Index mutual funds are purchased through investment companies on a daily basis, just like other mutual funds. An ETF is a fund that tracks an index, but may be bought and sold on the market throughout the day just like a single stock.

There's one more term that's very important for fund investors, and that is expense ratio: the combined operating costs and management fees charged to holders of a fund, expressed as a percentage of the fund's average annual net assets. So for example, if the expense ratio for a given fund is 2%, and your holdings in that fund have been worth an average of $1,000 over the course of the year, then for that year you will pay $20 to the fund provider.

Why index funds?

So what are the specific benefits of index investing?

1. Index funds are diversified

When buying individual stocks and bonds, investors run the risk of putting too many eggs in one basket. Investments that track the major indexes are by their very nature diversified, thereby limiting the amount of financial risk.

2. Index funds are low-cost

Index funds tend to have much lower expense ratios than their actively-managed peers, which have higher operating costs in the form of research, sales charges from trading activity, and the managers' time. Those costs are all passed on to the investor. Also (though this is relevant only to taxed accounts), the fact that passively-managed funds trade less often tends to make them more tax-efficient — that is, they generate fewer short- and long-term capital gains each year.

3. Index funds are tough to beat

Okay, but if the objective of index funds is to match the index, and often the objective of actively-managed funds is to beat the index, why would anyone want to pick the former?

Well, it turns out that despite all efforts to the contrary, a large majority of actively-managed funds perform below their benchmark index. For example, over a five-year period ending in mid-year 2010:

Fund Category Comparison Index Funds Underperforming the Index1
Large-cap core S&P 500 65.7%
Mid-cap core S&P MidCap 400 79.8%
Small-cap core S&P SmallCap 600 62.6%
International S&P 700 84.5%


Other academic studies find that there is no dependable persistence in performance: a fund manager who outperforms the associated index in one year is not likely to repeat that performance the next.2 Picking a consistently winning fund manager is no easier than picking consistently winning securities.

4. Index funds have performed better over the long term

Of course in the world of investing past performance is no guarantee of future results, and this is no less true of index funds.

But when it comes to retirement savings, your time horizon may be twenty years or more, which allows the advantages of index investing to really shine.

Consider this example: from 1980–2005, S&P index-based mutual funds averaged 12.3% net return (12.5% return less 0.2% expense ratio). The average actively-managed mutual fund provided a net return of 10.0% (after fees) during the same period. In other words, investors gained a 2.3% annual advantage by owning the index-based funds, which amounts to 42.5% greater returns over the 25-year period!3

Or to put some actual dollar numbers to those percentages: if you'd invested just $1,000 in an S&P index mutual fund in 1980, you'd be sitting on $17,080 in 2005. Someone who invested $1,000 in an average managed mutual fund would have only $9,820 in 2005. That's a pretty significant difference!

We used index mutual funds in this example because the first ETF wasn't created until 1993, but the lower expense ratios of ETFs versus index mutual funds can make the potential savings even more dramatic.
