a stock market index is an indicator that shows how the price of a certain set of assets is changingSo you need to have data from multiple companies or sectors in a fragment of the market.

These indicators are mainly used by the stock markets of different countries of the world and each of them can be integrated by companies with certain characteristics such as having a similar market capitalization or belonging to the same type of company, furthermore, there are some indices that only consider a handful of stocks to determine their value or others that consider hundreds of stocks.

Stock indices serve as indicator of confidence in stock market, business confidence, health of national and global economy and stock investment performance and shares of an entity. Generally, if investors are not confident, stock values ​​tend to fall.

They are also working to measure the performance of an asset manager and allow investors to make comparisons between return 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 study how company stocks tended to rise or fall together, he created two indices: one that contained the 20 largest railway companies (as it was the largest industry at the time) , as well as 12 shares of other types of companies

Today there are various indices and they can group together based on geography, industries, company size, or even asset classFor example, the U.S. Nasdaq index is made up of the 100 largest companies with broad technology connections 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 calculation method, but the main component is the market capitalization of each company that incorporates it. This is obtained by multiplying the daily value of the security on the corresponding stock market by the total number of shares outstanding on the market.

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

Reading a stock market index also means observing its evolution over time. Current indices always start with a fixed value based on security prices on their start date, but not everyone follows this method. Therefore, it can be misleading.

If one index sees an increase of 500 points in one day, while another only adds 20, it may seem that the former has performed better. But, if the first started the day at 30,000 points, and the other at 300, we can conclude that in terms of percentage, the gains for the second were considerable.
