The US economy, being the largest in the world, attracts the attention of a huge number of investors from many countries. The attractiveness of the US market is due to a wide variety of trading platforms, trading instruments, a huge number of issuing companies that place their securities here, including global giants of various industries. And it's not just American companies. The US stock market can be considered international. Shares and depositary receipts of companies from different countries, including Russia, China, Germany, etc. are traded here. Thus, the US market is still a huge opportunity for geographical diversification of investments. And it is very important for investors to monitor the state of the "market climate" in order to choose the most attractive assets or rebalance their portfolio in time. Stock indexes act as indicators reflecting the state of the entire market or individual industries.

What is an index?
Stock indexes are calculated summary indicators consisting of a specific list of companies that reflect the state of a sector, a group of companies on the stock market or the entire market. When it is said that the market has fallen or the market has grown with the indication of a specific percentage, then the growth or fall is judged primarily by the dynamics of the market index. That is, the index serves as an indicator, or they also say a "barometer", which speaks about the situation in the market or in a particular industry. That is, depending on the object and purposes of monitoring, investors monitor either industry indices or broad market indices.
Indexes are created and tracked by specialized providers or exchanges.
Indices are formed from the securities of issuers selected according to a certain criterion. There are no universal criteria. Each market index has its own set - from market value (capitalization), industry affiliation, place of registration to the value of free-float and the number of periods in which the company worked with profit. The composition of the indexes is not constant. They are reviewed with a certain frequency, that is, the so-called rebalancing occurs. Companies that no longer meet the established criteria are excluded from the index. And they are replaced by new participants. Usually, for an issuer, inclusion in the index is a significant driver of the growth of market quotations. And usually the price increase does not occur at the time of the announcement of the news or the revision of the index structure that has already taken place. Investors track information about candidates long before the news is announced, and therefore, at the time of rebalancing, this event is already embedded in the share price of new index participants.
The US stock market is one of the oldest. The first US stock index originated in the 1890s, when Charles Dow developed the Dow Jones Transportation Average index, based on data on eleven transportation organizations in the country. This index is still used today as the most recognized indicator of the American transport sector.
Thus, all stock indexes that exist now meet their specific goals. For example, the DJ Transportation transport index reflects the state of the transport industry, the DJ Financials financial index is an indicator of the state of financial sector companies, etc. So, monitoring the industry index allows you to assess the state of the industry for which the index is compiled. The main indices that display the general state of the US economy include the S&P500, NASDAQ100, etc. And then we will tell you more about these and other indexes.

US stock indexes, their types
There are about 765 stock indexes in the USA. These include all kinds of indices, starting with such well-known ones as the S&P500, Nasdaq100, Dow Jones Industrial, Dow Jones Composite Average (DJA), and ending with narrow-profile indices, where the PHLX Semiconductor semiconductor index can be cited as an example.
All existing US stock market indices can be grouped as follows:
- Industry indexes. As an example, indexes (the quantitative content of the index is indicated in parentheses):

- Broad market indices. These include the S&P500, S&P1500, DJ Composite, NYSE Composite, NYSE Amex Composite, Nasdaq Composite. They are used to assess the state of the entire market.
- TOP-capitalization indexes. This includes the S&P100, Dow Jones, Nasdaq100. These indexes allow us to assess the complex state of the most "expensive" companies grouped according to certain characteristics in various indexes.
- Indexes of companies with small and medium capitalization. This includes the Russell 2000, S&P 400, S&P 600. These indices reflect the assessment of the condition of companies with a relatively small market capitalization.

Popular US stock indexes
The main American indices will be considered in more detail here.
Dow Jones Industrial
The Dow Jones Industrial is one of the oldest indices of the US market, was invented and began to be used in 1896. The index is considered one of the main indicators of the American economy. It helps investors and stakeholders in a simple way to assess the market dynamics of the industrial sector of the economy.
Its structure is formed by the 30 largest industrial sectors, including such well-known Apple, Boeing, etc.
When selecting this index, the impeccable business reputation of the company, stable growth and interest from investors are taken into account (determined by the indicator of trade turnover). At the same time, there are no clearly defined quantitative criteria — the decision is made by a special committee. To include an issuer in the DJIA index, its headquarters must be located in the USA, and the bulk of its income must be generated here. In addition, it should be a system-forming company, that is, its activities should make a tangible contribution to the country's economy. And to top it all off, the company's securities must be listed on the NYSE or NASDAQ trading platforms.
Rebalancing is carried out every few months: if a company ceases to meet the criteria, then its shares leave the index. They are replaced by new issuers.
Dow Jones Composite Average
This US index appeared in 1934. It tracks the dynamics of share prices of 65 companies leading in their industries. This is an extended index based on three indexes:
- Dow Jones Industrial Average Yield Weighted (DJIYW) - DJIYW is an analogue for the main index, consisting of thirty companies on the DJIA list that have high profitability. Its member organizations must have a well-defined dividend payment schedule and excellent financial performance. The index is weighted according to their respective 12-month dividend yield.
- The Dow Jones Transportation Average (DJTA) is a transportation index that has existed for more than a hundred years and is leading the monitoring of companies providing logistics services throughout the United States and beyond.
- Dow Jones Utility Average (DJUA) – it consists of fifteen organizations from the field of utilities.
The presence of the DJA index allows you to more broadly assess the state of three indices at once at the same time, which may be convenient for certain investors.

- The market value (capitalization) is estimated at at least $6.1 billion.
- Free-float size ≥ 50%.
- The company should have been operating with positive operating profit for the last four quarters.

The S&P100 index is used in trading futures and options. As for the selection criteria, as a rule, the largest companies from the S&P 500 list with registered options are selected for inclusion in the index.

Those who occupy places from 101 to 125 places remain if they were in the top 100 according to the results of the previous year's review.

How to invest in US stock indexes
There are two main ways in which you can invest in a stock index: the purchase of futures and the purchase of ETFs. US index futures are traded on the Chicago Mercantile Exchange. Before making a decision to purchase futures, it should be remembered that futures are high-risk financial instruments, for their acquisition it is necessary to have either the status of a qualified investor, or an open account with a foreign broker, which is not always possible.
A more convenient way is to purchase a real-time stock index. Among the advantages are the following:
- The ability to invest in all stocks included in the index.
- The relatively low purchase price of the ETF.
- The need for a relatively small amount and a low exchange commission when purchasing one of the ETFs on the index, than when independently repeating the index by buying each index share. In other words, buying in real time allows you to achieve broad diversification of investments with small amounts of capital.
Currently, there are various data on a large number of popular stock indexes. For example, the S&P500 index has the following data:
- SPDR S&P 500 ETF (SPY) is the most popular ETF with a commission of 0.09%.
- iShares Core S&P 500 (IVV) ETF - this ETF ranks second in terms of trading turnover, the commission is 0.04%.
There is also data for other indexes:
- The Invesco QQQ (QQQ) ETF is an ETF on the Nasdaq 100.
- The Fidelity Nasdaq Composite Stock Index ETF tracking Stocks (ONEQ) is an ETF on the Nasdaq Composite.
- SPDR Dow Jones Industrial Average ETF - ETF for the Dow Jones Industrial Index.
- The iShares S&P 100 ETF (OEF) is an ETF on the S&P 100.
- The iShares Russell 2000 ETF (IWM) is a Russell 2000 ETF.
There is also a wide range of real-time industry indexes.
- Healthcare - SPDR Fund for the Healthcare Sector (XLV), Vanguard Healthcare ETF (VHT), iShares ETF for US Healthcare (IYH).
- Biotechnologies - iShares Nasdaq Biotechnological ETF (IBB-, SPDR S&P Biotechnological ETF (XBI), First Trust Amex Biotechnologies Index (FBT).
- Energy - ProShares Ultra Bloomberg Crude Oil (UCO), US Brent Oil Fund (BNO), US 12-month Natural Gas Fund (UNL).
- Finance – Vanguard Financial ETF (VFH), iShares USA Financial ETF (IYG), Invesco KBW Financial ETF with High Dividend Yield (KBWD).
- Transport – iShares Transportation Average ETF (IYT), SPDR S&P Transportation ETF (XTN). Average Transportation ETF (IYT).
The main disadvantage of real-time investing is that, in addition to companies with good financial performance and growth prospects, it may also include companies with poor performance or simply unprofitable.
However, there are options for "smart investing" in the index when you choose which companies to invest in. This approach implies spot investments and exclusion of ballast from the portfolio in the form of unprofitable companies that do not have fundamental sources of growth. This approach, firstly, reduces the risks of capital loss, and secondly, increases the efficiency of investment.

Conclusion
Stock indexes are one of the important tools available to investors. The main goal that is achieved with the help of this tool is to monitor the situation or, as investors also say, the temperature, the entire stock market or industries of interest. The family of American market indices occupies a special place in the world hierarchy due to its size and, of course, its "authority". Observing the dynamics of changes in certain indices allows you to make a judgment about the current state of both the entire US economy and its individual sectors, and helps in making an investment decision.
The presence of ETFs for stock market indices allows its participants to invest in a financial instrument that allows them to diversify their investments at a lower cost than when repeating the index independently. However, it must be remembered that buying futures or investing in an ETF of a separate index does not allow you to choose only the best representatives of the index, but forces you to purchase the entire set of shares of the companies that make up it, both "good" and "bad".
