What is a stock index and what is it for?

a stock index is an indicator that shows how the value of a certain set of assets changesfor which it takes data from different companies or sectors of a fragment 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 signatures with certain characteristics such as having a similar market capitalization or belonging to the same industry, in addition, there are some indices that only take into account a handful of shares to determine their value or others that consider hundreds of shares.

Stock market indices serve as indicator of confidence in the stock market, business confidence, the health of the national and global economy and the performance of investments in shares and company shares. Generally, if investors lack confidence, share prices tend to fall.

They also work to measure the performance of an asset manager and allow investors to analyze comparisons between return and risk; measure the opportunities of a financial asset or create portfolios.

This type of indicators began to be used at the end of the 19th century after journalist Charles H. Dow. closely watched how company stocks tended to go up or down together in price, so he created two indices: one containing the top 20 railroad companies (it was the biggest industry at the time), as well as 12 actions of other types of businesses

Today there are various indices and can be aggregated based on geographic location, sectors, company size, or even asset typeFor example, the US Nasdaq index is made up of the 100 largest companies mostly related to technology such as Apple (), Microsoft (), Amazon (AMZN), Facebook (FB), Alphabet (GOOG), Tesla (TSLA ), Nvidia (NVDA), PayPal (PYPL), Comcast (CMCSA), Adobe (ADBE).

How to read an index?

Each stock index has its own calculation method, but the main factor is the market capitalization of each firm that integrates it. This is obtained by multiplying the value of the day of the action in the corresponding stock market by the total number of shares that are in the hands of investors.

Companies listed on the stock exchange are required to present a balance of its composition. This report must be published every three or six months, as the case may be.

Reading a stock index also requires examining its variations over time. Current indices always start with a fixed value based on stock prices on your start date, but not everyone follows this method. Therefore, it can be a Source of misunderstandings.

If one index sees a 500-point increase in one day, while another only gains 20, it might seem like the first index outperformed. However, if the former started the day at 30,000 points and the other at 300, it can be deduced that, in percentage terms, the gains for the latter were larger.
