a stock market index is an indicator that shows how the value of a certain set of assets is changingfor which you need to have data from various companies or sectors in 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 firms with specific characteristics 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 stock market, business confidence, health of national and global economy and stock investment performance and shares of an entity. If investors are not confident, stock prices will tend to fall.

They are also working to measure the performance of an asset manager and they allow investors to compare 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 company stock prices tended to rise or fall together, he created two indexes: one that contained the 20 largest railway companies (because it was the largest industry in the era), as well as 12 shares of other types of companies

Currently, in our economy, there are various indices and they can be grouped by geographic location, industries, company size, or even asset typeFor 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 way of being measured, but the main factor is the market capitalization of each company that incorporates it. This is obtained by multiplying the value of the security on the corresponding stock market by the total number of shares that are 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 analyzing its evolution over time. New indices always start with a fixed value based on security 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, it can be deduced that in percentage terms the gains for the second were greater.
