Stock indices serve as indicator of confidence in the stock market, business confidence, the health of the national and global economy, and the performance of stock investments and shares of an entity. If investors are not confident, share prices will tend to fall.

They also work to measure the performance of an asset manager and allow investors to make a comparison between profitability and risk; measure the opportunities of a financial asset or create portfolios.

These types of indicators began to be used at the end of the 19th century after the journalist Charles H. Dow. To carefully analyze how the shares of companies tended to rise or fall together in price, he created two indices: one that contained the 20 largest railway companies (as it was the most important industry at the time), as well as 12 shares of other types of businesses

How to read an index?

Each stock index has its own way of calculating, but the main component is the market capitalization of each company that integrates it. This is obtained by multiplying the daily value of the bond in the corresponding stock market by the total number of shares that are in the market.

Companies listed on the stock exchange are required to present a balance of its composition. Said report must be published every three or six months, as the case may be.

Reading a stock index also implies paying attention to its evolution over time. Current indices always open at a fixed value based on stock prices on their start date, but not everyone follows this method. Therefore, it can lead to failures.

If one index adds 500 points in one day, while another only adds 20, it might appear that the former performed better. But, if the first started the day at 30,000 points and the other at 300, it can be concluded that, in percentage terms, the gains for the second were higher.
