A stock index is an indicator of general changes in prices of some or all securities that are presented on a certain market. It is also called a stock index. The index is compiled like a portfolio, in which the importance of each security corresponds to its weight in the market.
The main stock indices are the Dow 30 and S&P 500 in the USA, the Euro Stoxx 50 index of the Eurozone, the London FTSE 100 index, the German DAX, the Japanese Nikkei 225, and the famous US Tech 100 index of technology companies. In addition to these, there are many more stock indices in the world.
What is the use of a stock index
An index in trading is a very useful thing. Stock indices reflect the mood and activity in the markets, they read and show all the positive and negative movements of individual securities.
In addition, they provide an opportunity to assess the state of the world stock market and identify the current economic cycle.
Types of stock indices
Industry indices. They are calculated for a specific sector of the economy.
Consolidated or composite indices. They are calculated based on the prices of shares of various companies listed on the stock exchange. They serve as an indicator of the state of the economy and are used to forecast its development at all levels (global, country, industry).
Index trading is a popular way for traders to gain exposure to financial markets without having to directly invest in stocks, bonds, commodities, or other assets of individual companies.
Those new to financial markets often start by trading indices. Simply put, they trade index-tracking funds or baskets of stocks instead of buying and selling individual securities.
By tracking the performance of a large group of stocks, a stock index reflects the health of a broader market, such as a country’s stock market or a specific sector. This means that indices tend to be diversified.
Each of the world’s major financial markets has at least one stock index that represents it. For example, the S&P 500 (US500) is an index of the 500 largest companies in the United States. Because such benchmark indices often reflect the performance of the stock market as a whole, changes in their value indicate the health of the economy or industry sector they track.
Another benchmark index, the Euronext 100 (N100), tracks the performance of the largest stocks on the Euronext European exchange. It includes companies listed in the Netherlands, France, Belgium, Portugal and Luxembourg. Other major indices include the UK’s FTSE 100 (UK100), Germany’s DAX 40 (DE40), Hong Kong’s Hang Seng (HK50) and Japan’s Nikkei 225 (J225).
Indices provide fund managers with benchmarks for evaluating the performance of their active management. Fund providers also create passive index funds, including related derivatives, that investors can buy and sell.
Passive funds, also known as tracker funds, hold stocks in the same proportions as the index to match its performance. Active funds are run by fund managers who aim to beat the index. Fund managers charge investors an annual percentage of the fund's value as a fee for their services.
Exchange-traded funds (ETFs) are an increasingly popular way for investors to get started trading stock indexes. ETF managers like Vanguard charge relatively low fees, allowing investors to keep more of their returns.
Because ETFs trade on exchanges, their prices fluctuate throughout the trading session, unlike a mutual fund, whose price is set once a day. ETFs can be bought and sold quickly and easily through stock trading platforms.
Dividends from shares in an index-tracking fund can be distributed to investors through a distribution fund or reinvested back into an accumulation fund.
It is important for both new and experienced traders to stay up to date with market events to make informed trading decisions.
To trade successfully, you need to follow expert commentary and conduct technical and fundamental analysis of indices and their components, whether they are stocks, bonds, commodities or currency pairs.
Keep an eye on macroeconomic data that can impact indices, as well as government announcements and geopolitical events that can cause markets to rise or fall.
