a stock market index It is an indicator that shows how the price of a given set of assets is movingit therefore uses data from different companies or sectors of a part 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 different specificities like having a similar market capitalization or being in the same type of industry, similarly, some indices 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 the stock market, business confidence, the health of the national and global economy and the performance of stock investments and shares of a company. Generally, if investors are not confident, stock prices tend to fall.

They are also working to measure the performance of an asset manager and they allow investors to have comparisons 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 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 in humanity there are various indices and They can group together based on geography, industries, company size, or even asset classFor 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 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 notified every three or six months, as the case may be.

Reading a stock market index also requires analyzing 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 adds 500 points in one day, while another only adds 20, it may appear that the former has outperformed. 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.
