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

These indicators are mainly used by stock exchanges in various countries and each of them can be integrated by signatures with different specificities like having a similar market capitalization or belonging to the same industry, similarly, some indexes only consider a handful of stocks to determine their value or others that consider hundreds of stocks.

Stock market indices serve as indicator of confidence in stock market, business confidence, health of national and global economy and stock investment performance and shares of a company. Generally, if investors are not confident, 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 see carefully how company stocks tended to rise or fall together in price, he therefore created two indices: one that contained the 20 largest railroad companies (since that 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 associate according to their location, their sectors, the size of the company or the type of assetFor example, the American Nasdaq index is made up of the 100 largest companies mainly 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).

Each stock index has its own calculation method, but the main component is the market capitalization of each firm that integrates it. This is obtained by multiplying the daily value of the bond in the corresponding stock market by the total number of shares outstanding in the market.

Listed companies are required to present a balance sheet of its composition. This report must be made public 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 stock prices on their start date, but not everyone follows this method. Therefore, this may lead to inaccuracies.

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. However, if the first started the day at 30,000 points and the other at 300, we can deduce that in percentage terms the gains for the second were considerable.
