a stock index It is an indicator that shows how the price of a given set of assets evolvesso it collects data from various companies or sectors of a fragment of the market.

These indicators are used mainly by the stock markets of the countries and each of them can be integrated by signatures with different specificities such as having a similar market capitalization or belonging to the same industry, 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 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 a company. If investors are not confident, 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.

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

Today in our economy there are various indices and they can congregate based on their location, sectors, company size or even asset classFor example, the US Nasdaq index is made up of the 100 largest largely technology-related companies such as Apple (AAPL), Microsoft (MSFT), Amazon (AMZN), Facebook (FB), Alphabet (GOOG), Tesla (TSLA), Nvidia (NVDA), PayPal (PYPL), Comcast (CMCSA), Adobe (ADBE).

Each stock index has its own way of being measured, but the main component is the market capitalization of each company that integrates it.

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

If one index boosts by 500 points in a day, while another only adds 20, it might appear that the former outperformed. However, if the former started the day at 30,000 points and the other at 300, it can be deduced that, in percentage terms, the gains for the latter were higher.
