Why do investors use indexes?
Financial professionals use indices to benchmark the portfolios they manage against market performance. Even individual investors can evaluate how their investments are performing relative to the market using indices as a reliable reference point.
An index is a list of all the names, subjects and ideas in a piece of written work, designed to help readers quickly find where they are discussed in the text. Usually found at the end of the text, an index doesn't just list the content (that's what a table of contents is for), it analyses it.
A stock market index shows how investors feel an economy is faring. An index collects data from a variety of companies across industries. Together, that data forms a picture that helps investors compare current price levels with past prices to calculate market performance.
An index measures the price performance of a basket of securities using a standardized metric and methodology. Indexes in financial markets are often used as benchmarks to evaluate an investment's performance against.
Indexes are used to monitor markets, benchmark performance and invest passively. For investors, indexes are important statistical tools that track the performance of an asset class, such as U.S. large-cap stocks or U.S. investment-grade corporate bonds.
The three most popular stock indexes for tracking the performance of the U.S. market are the Dow Jones Industrial Average (DJIA), S&P 500 Index, and Nasdaq Composite Index.
The key advantage of using the S&P 500 as a benchmark is the wide market breadth of the large-cap companies included in the index. The index can provide a broad view of the economic health of the U.S. because it covers so many companies in so many different sectors.
But there is one main distinction between these two indexes: The S&P 500 has 500 of the largest companies, which is why some investors believe it provides a more accurate picture of the economy. The Dow Jones, on the other hand, is composed of 30 blue-chip companies.
An index tracks the performance of a group of preselected investments, such as stocks. For example, the S&P 500 index tracks the performance of 500 of the largest U.S. companies. Investors gauge the performance of stocks, bonds or mutual funds by comparing them with the performance of an index.
Benefits of investing in index funds
Since an index fund mimics its underlying benchmark, there is no need for an efficient team of research analysts to help fund managers pick the right stocks. Also, there is no active trading of stocks. All these factors lead to low managing cost of an index fund.
Why is index trading important?
Lower transaction costs: Compared to trading individual stocks, trading indices incurs lower transaction costs, as you can gain exposure to a broad range of securities through a single trade.
As with other mutual funds, when you buy shares in an index fund you're pooling your money with other investors. The pool of money is used to purchase a portfolio of assets that duplicates the performance of the target index. Dividends, interest and capital gains are paid out to investors regularly.

Individual stocks tend to be far more volatile than fund-based products, including index funds. This can mean a bigger chance for upside … but it also means considerably greater chance of loss. By contrast, the diversified nature of an index fund generally means that its performance has far fewer peaks and valleys.
Probably the world's best-known and most widely used stock market index, the Dow Jones Industrial Average (DJIA) consists of 30 largest traded companies in the United States. Many investors use market indices for managing their investment portfolios and following the financial markets.

Buffett's favorite fund
He even noted that his will instructs that 90% of the cash inherited by his family be invested in such a fund. An S&P 500 index fund certainly meets Buffett's advice about owning a broad cross-section of businesses. These funds invest in the 500 large-cap companies that make up the S&P 500.

Why don t more people invest in the S&P 500?
It might actually lead to unwanted losses. Investors that only invest in the S&P 500 leave themselves exposed to numerous pitfalls: Investing only in the S&P 500 does not provide the broad diversification that minimizes risk. Economic downturns and bear markets can still deliver large losses.
Historical Performance
Amidst recent market volatility, the Nasdaq-100 Total Return Index has consistently sustained cumulative total returns exceeding twice the performance of the S&P 500 Total Return Index.
The main drawback to the S&P 500 is that the index gives higher weights to companies with more market capitalization. The stock prices for Apple and Microsoft have a much greater influence on the index than a company with a lower market cap.

Most index funds pay dividends to their shareholders. Since the index fund tracks a specific index in the market (like the S&P 500), the index fund will also contain a proportionate amount of investments in stocks. For index funds that distribute dividends, many pay them out quarterly or annually.
Experts agree that for most personal investors, a portfolio comprising 5 to 10 ETFs is perfect in terms of diversification.

While the S&P 500 is widely regarded as the best indicator of how the stock market is faring, other market indices can give you a different view based on the type of companies they track. Dow Jones, for instance, follows 30 of the largest companies in the country from various industries.
What is index fund in simple words?
Index funds are investment funds that follow a benchmark index, such as the S&P 500 or the Nasdaq 100. When you put money in an index fund, that cash is then used to invest in all the companies that make up the particular index, which gives you a more diverse portfolio than if you were buying individual stocks.
The average stock market return is about 10% per year, as measured by the S&P 500 index, but that 10% average rate is reduced by inflation. Investors can expect to lose purchasing power of 2% to 3% every year due to inflation. Learn more about purchasing power with NerdWallet's inflation calculator.
