A Comprehensive Overview
Introduction
The United States stock market, one of the most dynamic and influential financial markets globally, serves as a barometer of economic health and investor sentiment. US shares, representing ownership in publicly traded companies, are central to the economic landscape, offering a myriad of opportunities and challenges for investors. This article delves into the intricacies of US shares, exploring their significance, key market players, and the factors influencing their performance.
Before you start looking at investment opportunities in the US, it is important to spend some time understanding the way the markets work there and factors that influence them. An essential aspect of understanding the equity market of any country is the list of stock market indices. They act like a measuring gauge that offers a comprehensive view of the market conditions in the country. They can help you identify market trends and investor sentiment without getting into individual social, political, and other macroeconomic factors. Today, we will talk about stock market indices in the US and share some essential information about them.
What is a Stock Market Index?
A stock market index is a hypothetical portfolio of stocks that represents a certain segment of the market. There are different ways in which an index is formed and calculated.
Primarily, indices use a weighted average calculation to arrive at their value. This weighted average can be based on price-weightage, market capitalization-weightage, etc.
If an index follows the price-weightage method, then a change in the price of holdings with the highest price will impact the index more than those with a lower price. On the other hand, if the index follows a market cap-weighting method, then price becomes irrelevant and the index is impacted primarily by changes in the price of stocks with higher market capitalizations.
In the US, there are over 5000 stock market indices. Yes, you read that right – 5000+ stock market indices. There is an index for almost any conceivable sector or segment of the economy and the market. Of these, some indices are followed by most investors regularly as they offer a clear picture of the overall performance of the US markets. These are:
- S&P 500
- Dow Jones Industrial Average
- Nasdaq Composite
- Wilshire 5000

The US stock market operates through two primary exchanges: the New York Stock Exchange (NYSE) and the Nasdaq. The NYSE, the world’s largest equity stock exchange, boasts a long history and hosts a diverse array of companies.
While there are numerous indices managed by various US stock exchanges, the most prominent indices include the S&P 500, the Nasdaq Composite, and the Dow Jones Industrial Average (DJIA). These indices offer insights into the overall market performance and are crucial benchmarks for investors.
The S&P 500 consists of the top 500 companies in the US, sorted by market capitalisation. It represents a broad cross-section of the economy and is widely regarded as a barometer for the health of US markets.
The Dow Jones Industrial Average, comprising 30 prominent companies, is a price-weighted index that provides insight into the performance of large-cap stocks. While it represents a smaller sample compared to the S&P 500, the DJIA is closely watched by investors and analysts alike.
Investors often construct portfolios that mirror these indices to gain exposure to the broader market. This approach allows for diversification and risk mitigation, as the indices encompass a wide range of companies and industries.
How Is The US Stock Market Regulated?
The US stock market is regulated primarily by the Securities and Exchange Commission (SEC), founded in 1934. This federal agency enforces securities laws, oversees the securities industry, and safeguards investor interests. The SEC’s mandate is to uphold transparency, fairness, and efficiency in securities markets while combating fraud and abuses. Through regulatory oversight, the SEC aims to give investors confidence and maintain the integrity of the US stock market.
