Key Takeaways
- Indexing is a statistical measure for tracking economic data, like inflation and GDP growth.
- Indexes serve as benchmarks for assessing the performance of fund managers and portfolios.
- Passive investment strategies often use indexing to track market index returns, offering diversification and lower costs.
- Popular indexes include the S&P 500 and Dow Jones, which help track market and economic performance.
- Index funds generally have lower management fees and are more tax-efficient than actively managed funds.
What Is Indexing?
Indexing is the practice of compiling economic or financial market data into a single metric or comparing data to such a metric. In economics, indexes can directly impact people’s livelihoods, for example in the form of cost-of-living adjustments that are indexed to inflation. In investing, indexes serve as benchmarks for measuring the performance of portfolios and fund managers. Indexing also means passively investing in market indexes to replicate broad market returns, instead of selecting individual stocks.
How Indexing Works in Economics and Finance
Indexing is used in the financial market as a statistical measure for tracking economic data. Indexes created by economists provide some of the market’s leading indicators for economic trends. Economic indexes closely followed in the financial markets include the Purchasing Managers’ Index (PMI), the Institute for Supply Management’s Manufacturing Index (ISM), and the Composite Index of Leading Economic Indicators. These indexes are tracked to measure changes over time.
Statistical indexes may also be used as a gauge for linking values. The cost-of-living adjustment (COLA) is a statistical measure obtained through analysis of the Consumer Price Index (CPI) that indexes prices to inflation. Many pension plans and insurance policies use COLA and the Consumer Price Index as a measure for retirement benefit payout adjustments with the adjustment using inflation-based indexing measures.
The Role of Indexing in Financial Markets
An index is a method to track the performance of a group of assets in a standardized way. Indexes typically measure the performance of a basket of securities intended to replicate a certain area of the market.
These could be a broad-based index that captures the entire market, such as the Standard & Poor’s 500 Index or Dow Jones Industrial Average (DJIA). Indexes can also be more specialized, such as indexes that track a particular industry or segment. The Dow Jones Industrial Average is a price-weighted index, which means it gives greater weight to stocks in the index with a higher price. The S&P 500 Index is a market capitalization-weighted index, which means it gives greater weight to stocks in the S&P 500 Index with a higher market capitalization.
Index providers have numerous methodologies for constructing investment market indexes. Investors and market participants use these indexes as benchmarks on performance. If a fund manager is underperforming the S&P 500 over the long term, for example, it will be hard to entice investors into the fund.
Indexes also exist that track bond markets, commodities, and derivatives.
Harnessing Indexing for Passive Investment Strategies
Indexing is broadly known in the investment industry as a passive investment strategy for gaining targeted exposure to a specified market segment. The majority of active investment managers typically do not consistently beat index benchmarks. Moreover, investing in a targeted segment of the market for capital appreciation or as a long-term investment can be expensive given the trading costs associated with buying individual securities. Therefore, indexing is a popular option for many investors.
An investor can achieve the same risk and return of a target index by investing in an index fund. Most index funds have low expense ratios and work well in a passively managed portfolio. Index funds can be constructed using individual stocks and bonds to replicate the target indexes. They can also be managed as a fund of funds with mutual funds or exchange-traded funds as their base holdings.
Tip
Most brokerages will offer index funds that are benchmarked against the major stock market indexes. These can be mutual funds or exchange-traded funds.
Because index investing is passive, index funds typically have lower management fees and expense ratios than active funds. Tracking the market without a portfolio manager keeps fees low. Index funds are also more tax-efficient as they trade less often than active funds.
Utilizing Tracker Funds in Indexing Strategies
More-complex indexing strategies may seek to replicate the holdings and returns of a customized index. Customized index-tracking funds have become a low-cost way to invest in a screened set of securities. Tracking funds are based on a range of filters, including:
- Fundamentals
- Dividends
- Growth characteristics
Tracker funds aim to select the best stocks within a category. For example, a fund may pull from the best energy companies within the broader indexes that track the energy industry.
How Is Indexing Used In Investing?
In investing, indexing is a passive investment strategy. You create a portfolio that tracks a common market index, such as the S&P 500 with the goal of mimicking the index’s performance. As a strategy, indexing offers broad diversification, as well as lower expenses, than investing strategies that are actively managed.
What Is a Broad Market Index?
A broad market index tracks the performance of a large group of stocks. This large group is chosen to represent the entire stock market. A broad market index adds significant diversification to any portfolio. Examples of broad-based indexes include the S&P 500 Index and the Russell 3000 Index.
Is Indexing a Smart Way to Invest?
Indexing is a good investment strategy for many people. It creates a diversified portfolio, and it usually requires lower fees and expenses than an actively managed fund. It also mimics the broader stock market, which over the long run will generally perform better than any single person picking stocks.
The Bottom Line
Indexing refers to compiling economic or market data into a single metric. It can also involve comparisons to such a metric in order to measure change or performance. In economics, there are many indexes that summarize or reflect economic and market activity. For example, cost-of-living adjustments to Social Security payments are indexed to inflation.
In investing, indexes are benchmarks that are used to measure the performance of fund managers and portfolios. Indexing can refer to a passive investing strategy that aims to track broad market returns.
