What is a stock index and what is it for?

a stock index is an indicator that measures the evolution of the value of a certain set of assetsso it collects data from various companies or sectors of a part of the market.

These indicators are mainly used by the stock exchanges of the countries and each of them can be integrated by firms with specific characteristics such as having a similar market capitalization or belonging to the same type of industry, likewise, 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. Generally, if investors lack confidence, share prices will tend to fall.

They also work to measure the performance of an asset manager and allow a comparison to be made 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. carefully analyzed 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 there are various indices and they can be agglomerated according to their geography, sectors, the size of the companies 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 calculation method, but the main component is the market capitalization of each company that integrates it. This is obtained by multiplying the value of the day of the share in the corresponding stock market by the total number of shares that are in circulation in the market.

Listed companies are required to present a balance of its composition. Said report must be made public every three or six months, as the case may be.

Reading a stock index also requires paying attention to its changes over time. Current indices always start with a fixed value based on security prices on your start date, but not everyone follows this method. Therefore, it can be misleading.

If one index grows 500 points in a day, while another only gains 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, you can see that, in percentage terms, the gains for the latter were more significant.
