What is a stock index and what is it for?

a stock index It is an indicator that is used to know the evolution of the value of a certain set of assets. so it collects data from various companies or sectors of a part of the market.

These indicators are mainly used by the stock exchanges of each country and each of them can be integrated by firms with specific characteristics such as having a similar market capitalization or belonging to the same industry, also, 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. If investors lack confidence, share prices will tend to fall.

They also work to measure the performance of an asset manager and they allow investors to make a comparison between profitability 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. carefully researched how company stocks tended to go up or down in price together, 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

Currently there are various indices and they can be associated based on their geography, sectors, company size or even the type of assetFor example, the US Nasdaq index is made up of the 100 largest companies mostly 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 to read an index?

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

Companies listed on the stock exchange are required to present a balance of its composition. Said report must be notified every three or six months, as appropriate.

Reading a stock index also requires noticing its changes 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 confusing.

If one index rises 500 points in a day, while another only gains 20, it might appear that the first index outperformed. But, if the first one started the day at 30,000 points and the other one at 300, it can be deduced that, in percentage terms, the gains for the second one were more remarkable.
