What is an Index?

Indices are a method of measuring the value of a market segment. The best known indices measure the performance of stock markets. An index is a mathematical construct, so you cannot invest in it directly. However, there are index funds that attempt to resemble the development of indices.

Some important stock market indices:

Types of indices

In a market-value weighted or capitalisation-weighted index such as the Hang Seng Index, the size of the companies are factored in. Here, a large change in the price of the largest component of the index can result in a relatively large change of the index value.

In a price-weighted index such as the Dow Jones Industrial Average, the price of each component stock determines the value of the index. Here, the price movement of even a small single company can strongly influence the index.
