Index trading provides an opportunity to trade in the financial markets without the need to invest in individual stocks separately. An index acts as a “basket” containing shares or other financial instruments, where the total value evolves in line with the overall performance of the individual shares or other financial instruments that are part of the index.
To calculate the market value of an index, many indices use what is called a “weighted average”. This means that the shares or instruments with the highest market capitalization or share price are given greater weight in the calculation of the overall index. This approach reflects the idea that the stocks or instruments with higher values are more likely to impact the industry or market segment that the index represents.
Thus, changes in the value of the most significant stocks or instruments will have a greater impact on the overall index. This gives investors an indication of the overall performance of the underlying sector or market that the index represents. Index trading thus provides a diversified approach as it allows exposure to multiple companies or sectors through a single trade.
Indices are often used as benchmarks to assess how a portfolio, investment or market is performing relative to a broader spectrum. They are also used as a basis for developing investment products such as ETFs, funds and derivatives

More information
What are indices?
Indices are composite measurements that represent the value or performance of a group of stocks, commodities, bonds or other financial instruments within a particular market or sector. These measurements are often used as reference points to evaluate and compare the performance of investments or the market as a whole.
What does composition matter?
Indices are composed of a group of selected assets, such as stocks from a specific market or sector. These assets are usually selected based on criteria such as size, industry, geographical location or other relevant factors.
What does weighting mean?
Indices can be weighted in different ways. Some use market capitalization weighting, where larger companies have a greater influence on the index based on their market capitalization. Other indices may use equal weighting, where each component has the same influence regardless of size.
