a stock market index It is an indicator that shows how the price of a set of assets is movingit therefore collects data from several companies or sectors of a market fragment.

These indicators are mainly used by the stock markets of various countries and each of them can be integrated by companies with specific characteristics like having a similar market capitalization or belonging to the same type of company, there are also 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. If investors lack confidence, stock prices will 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

There are currently various indices and They can be grouped by geographic location, industries, company size, or even asset class.For 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 factor 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 disclosed every three or six months, as the case may be.

Reading a stock market index also requires noticing its changes over time. New indices always start with a fixed value based on stock prices on their start date, but not everyone follows this method. Therefore, it can be misleading.

If one index gains 500 points in one day, while another only gains 20, it may seem that the former has 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 greater.
