What is a stock index and what is it used for?

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

These indicators are mainly used by the exchanges of each country and each of them can be integrated by signatures with different specificities 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 the company. 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 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 analyze how company stock prices tended to rise or fall together, he created two indexes: one that contained the 20 largest railway companies (as it was the most important industry in the era), 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 typeFor 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).

How is a stock index measured?

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 daily value of the bond 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 submitted 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 increases by 500 points in one day, while another adds only 20, it may seem that the first has outperformed. But, if the first started the day at 30,000 points, and the other at 300, we can conclude that in percentage terms, the gains of the second were higher.
