What is a stock index and what is it for?

a stock index It is an indicator that shows how the price of a certain set of assets changesfor which it collects data from different companies or sectors of a part of the market.

These indicators are mainly used by the stock exchanges of various countries and each of them can be integrated by firms with specific requirements such as having a similar stock market capitalization or belonging to the same type of business, in addition, there are some indices that only take into account a handful of shares to determine their value or others that consider hundreds of shares.

Stock market indices serve as indicator of confidence in the stock market, business confidence, the health of the national and global economy and the performance of investments in shares and shares of an entity. If investors lack confidence, share prices 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.

This type of indicators began to be used at the end of the 19th century after journalist Charles H. Dow. He looked closely at how company stocks tended to go up or down together in price, so he created two indices: one containing the top 20 railroad companies (since it was the biggest industry at the time), as well as 12 actions of other types of businesses

Currently in humanity there are various indices and they can be grouped according to their location, sectors, company size or even the type of assetFor example, the US Nasdaq index is made up of the 100 largest companies mostly related to technology such as Apple (AAPL), Microsoft (MSFT), Amazon (AMZN), Facebook (FB), Alphabet (GOOG), Tesla (TSLA ), Nvidia (NVDA), PayPal (PYPL), Comcast (CMCSA), Adobe (ADBE).

How is it calculated and how to read them?

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

Listed firms are required to present a balance of its composition. This report must be published every three or six months, as appropriate.

Reading a stock index also implies being careful of its evolution over time. Current indices always open with a fixed value based on security prices on your start date, but not everyone follows this method. Therefore, it may seem misleading.

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