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 Author: Dan Caplinger. A market index is a hypothetical portfolio of investment holdings that represents a segment of the financial market. The calculation of the index value comes from the prices of the underlying.

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.

Indexes also vary in size, with some tracking just a handful of stocks and others looking at thousands. Each index serves a unique purpose because different investors are interested in different sectors. Tracks 30 of the largest and most important U.

A barometer of the overall stock market's performance that contains companies, weighted by market cap, from across different sectors. This index includes the roughly 3, companies that are part of the Nasdaq stock exchange and is predominately focused on technology.

Beyond these famous stock market indexes, however, there are thousands of lesser-known indexes. You can find indexes that reflect the performance of stocks in a certain country or that do business in a given sector of the economy.

Some indexes separate large, mid-sized, and small companies into different categories. Others use investing strategies like growth, value, or dividend investing to select component stocks. Pretty much any type of stock you might be interested in, there's an index for that. The rise of index mutual funds and ETFs has led to a proliferation of indexes to help fund managers use passive investing strategies to minimize costs and let investors tailor their portfolio exposure as precisely as they like.

Learn how to invest in index funds. Reading an index correctly requires that you look at how the index value changes over time. New stock market indexes always begin with a certain fixed value based on the stock prices on its starting date. Thereafter, future index values measure rising and falling prices for those component stocks. Not all stock market indexes use the same starting value, however, so just measuring index changes by using points can be misleading. For instance, if one index rises points in a day while another rises just 10 points, it might seem as though the first index performed far better.

A higher percentage gain means a bigger profit for you if you invest in funds that track the index, so it's better to focus on percentages than on point movements.

Knowing which stocks are in an index can tell you which parts of the stock market are contributing to that index's performance and can explain why other indexes might not be performing the same way.
