Stock Market Indices: A Guide to the World’s Leading Benchmarks

The stock market is a type of financial market that deals exclusively with buying and selling stocks. Stocks are an asset class that represents partial ownership in a company. A trader or investor buys stocks in a company of their choosing through the stock market at a defined price. The stock price fluctuates and is affected by factors such as the economy, market sentiment, and world news.

The fluctuating prices of stocks make them a great asset class for speculative trading via CFDs. Contract for differences, or CFDs, is a trading strategy that allows traders and investors to speculate on price movements without owning the asset. In speculative trading, any position is only held for a short time, and the major focus is on buying and selling assets quickly to profit from the smallest price changes. 

An important aspect of the stock market is the stock market indices, a statistical measure that presents the performance of a group of similar stocks or assets in an industry. These indices are very important in the financial markets as they are used to judge the overall market of that particular industry. A few of the most important industries include technology, agriculture, banking, and the weapon industry. Some of the most renowned indices include the S&P 500, which tracks 500 of the largest publicly traded companies; NASDAQ Composite, a technology-focused index; and FTSE 100, which tracks the top 100 largest companies on the London Stock Exchange. 

Indices serve as a benchmark for measuring and judging market performance. Their price movements reflect how the broader market is moving. Indices are also a great source of measuring an industry’s performance over time. This is why long-term investors closely follow indices, as tracking them gives them an idea of where to capitalise on their investment and where to close the trade in the future.  

As speculative trading can be conducted via stock CFDs and indices CFDs. Traders speculate on the changing prices of the indices and make a profit. This sort of trading can be easily carried out online through trading platforms that offer users a number of technical analysis tools. Both methods of CFD trading, either with stocks or with stock indices, involve a certain level of risk. 

In this article, we cover everything you need to know about stock market indices, including how they are calculated, how they work as benchmarks and more.  

What Is a Market Index?

A Market Index is a statistical value representing the overall performance of a group of similar assets in an industry. Different market indices exist, such as stock market indices and forex market indices. By using these indices, traders can get an in-depth idea of where the market is heading, which companies are emerging, which might be lacking, and so on. 

Based on their structure, market indices can be divided into three types: precise-weighted indexes, market-capitalization indices, and equal-weighted indexes. In a price-weighted index, each stock is weighted according to its share price; for example, the Dow Jones Industrial Average is a price-weighted index. A market-capitalization index contains companies with a larger market cap for example, the S&P 500 is a market-capitalization weighted index. Finally, the equal-weighted index contains components with the same weight regardless of their share price and market cap. 

Market indices represent a group of assets, each known as a component of the indices or its constituent. For example, Apple is a component of the Nasdaq indices. These components are carefully selected and meticulously placed in the index based on their stock unit price, performance over time, and popularity in the category. 

If a tech-based index performs well over a certain period of time, it can be assumed that the tech industry is booming and that people are showing interest in this sector. This can hint at investors who may invest more capital, and the government may offer subsidies or new policies in favour of the tech industry. 

This is why it is often said that the market indices act as indicators of the economic health of a sector, state, and country. These indices offer insights into the general market performance and shed light on sector-specific information, portraying true market and investor sentiment. All these factors are used to judge the state’s economic health. It is a win-win situation for everyone if the indices perform well, except for the speculative traders who speculated that the price of a certain index will go down.  

How Stock Market Indices Are Calculated

Now that we know what stock market indices are let us look at how they are calculated. The most widely known method of calculating stock market indices is through weighting methods. These methods determine how each individual stock contributes to the index’s overall value. Generally, there are three weight-based methods for calculating stock market indices:

Price-Weighted Index 

This method calculates the overall index value based on each company’s share price. This method is very well-known because stocks with higher share prices have a greater effect on the index’s performance regardless of the size and value of the company in the market. The formula for calculating a price-weighted index is:

Weight = SP1/(SPI + SP2 +… + Sn)

Where SP = Stock price of each constituent company of an index. The biggest example of price-weighted indices is the Dow Jones Industrial Average, which comprises the top 30 U.S. companies. 

Market-capitalization-Weighted Index 

This method is based on a company’s outstanding shares in the market. The higher a company’s market cap, its influence on the indices increases. To calculate a market-capitalization-weighted index, the following equation is used:

Market Cap=Price Per Share×Shares Outstanding

The most famous example of a market-capitalization-weighted index is the S&P 500, which tracks the top 500 companies in the USA. 

Equal-Weighted Index 

An equal-weighted index is calculated regardless of the share price and market capitalisation. This means that each component equally influences the overall index value. Following is the formula to calculate an equal-weighted index:

EWI Value = (Stock Price 1*Assigned Weight) + (Stock Price 2*Assigned Weight) + (Stock Price 3*Assigned Weight) + (Stock Price N*Assigned Weight)

A good example here is the S&P 500 Equal Weight Index. 

Leading Stock Market Indices

Here, we look at some of the most influential indices in the world:

Dow Jones 

Dow Jones is one of the oldest known indices in the world and probably the most followed one as well. It tracks the top 30 publicly traded companies in the U.S. stock exchanges. This is why it is considered an effective index to judge the American economy. Dow Jones is a price-weighted index. The top components of Dow Jones include Apple, Boeing, and Microsoft. 

NASDAQ

NASDAQ is an index that purely tracks technology-based companies on the USA stock exchange. It is primarily a market-capitalization weighted index and is famous in tech. The most notable components of NASDAQ include Apple, Microsoft, and NVIDIA. This is why this index is famous among global investors and young adults interested in technology also look at this stock index closely.  

FTSE 100

The Financial Times Stock Exchange, or the FTSE, tracks the top 100 companies by market capitalisation in the London Stock Exchange. This index reflects the economic condition of the United Kingdom and, thus, is a very important index to monitor. The most notable components of the FTSE 100 include AstraZeneca and Unilever.

Nikkei 225

Nikkei 25 is a Japanese-based price-weighted index that tracks 225 leading companies on the Tokyo Stock Exchange (TSE). It reflects the country’s economic trends. Mitsubishi and Toyota are the most notable components of the Nikkei 225 index. 

In addition to these, traders can access many different indexes. The key here is to understand the purpose of the index before trading them. Different trading platforms offer a snippet of information about the index you follow or want to trade in, but it is highly suggested that you conduct your own research. Additionally, for beginners in trading, we recommend using a demo account for practice first. A demo account is a trading account which mimics real-world scenarios and conditions where the trader can trade and look at the outcome without any real money involved. This is useful because the trader learns to use the platform, form quick decisions, and can learn to anticipate price movements which is all necessary for effective trading. 

Role of Indices in CFD Trading

Indices are based on stocks of publicly traded companies. Several factors, including the economy, market trends, world news, policy change, and public sentiment, influence the prices of these companies, the company’s performance, and a few more. So, the stock prices can be highly riddled with fluctuations. The most common trading strategy regarding indices is holding a position for a long time, where, for the investor, small fluctuations are of no concern as the investment will pan out after a good number of years. 

Due to these fluctuations, another trading technique is also seen, which is speculative trading using CFDs. Contract for difference or CFDs is a strategy where traders capitalise on the price movements of the indices without owning the assets. They hold the position for a very short period and sell it when profit has been made, or imminent loss can be seen. This technique is very interesting because it allows greater flexibility, leverage, and potential for making a profit in an uptrend or downtrend market. After all, the key here is accurate speculation and not upward-moving stock prices. 

There are quite a few different risks involved with index CFD trading. These include sudden and unanticipated price movements that can cause losses, traders being exposed to the full value of the position, and margin calls, where brokers may require additional funds to maintain a position if the market moves against a trader’s position. Fortunately, in CFD trading, traders can deploy multiple risk-aversion techniques to save them from sudden losses, including stop-loss orders, take-profit orders, and activating technical indicators. 

Regional Indices

Unlike the indices that track top global companies either by stock price or market capitalisation, regional indices track the performance of the companies within a specific economic region or a country, which is why they are called regional indices. They are equally important to the global indices as they shed important information about the underlying area of interest. The two most famous regional indices include the ASX 200 in Australia and the DAX in Germany. Here we look at their details:

ASX 200 

This Australian index tracks the top 200 companies in the Australian Securities Exchange, which companies in the finance, healthcare, and mining sectors dominate. Therefore, this index is a strong indicator of Australia’s economic health. This is an important tracked index because Australia is a major global coal exporter, highly regarded in the Asia-Pacific region. 

DAX 

The DAX tracks the top 40 of Germany’s largest traded companies. It is, therefore, a key measure of the broader European economy and its stability. It contains components related to the banking, healthcare, technology, and industrial sectors.

These indices may be regional, but they affect the global markets in multiple ways. This is why tracking them is essential and highly recommended to traders and investors. 

Advantages of Monitoring Indices

Now that we know what indices are, their characteristics, components, workings, and much more, let us look at their advantages. 

Market Trends

First and foremost, indices reflect the overall market trends, which is advantageous for any trader. Based on the information gathered from here, traders can make viable decisions and potentially decide on optimal entry and exit points from a trade. 

Sector Health

As some indices track sector-specific companies, they can be a good source of information on the sector’s health and performance. 

Economic Performance 

Bigger indices like the S&P 500 cover major sectors of the economy. Tracking such indices can reflect the country’s overall economic performance.

Benchmarking

The most important advantage of any indices is that they are often used as benchmarks for measuring the performance of a portfolio.
