Stock indices… What for?

a stock index is an indicator that shows how the value of a set of assets changesso it takes data from various companies or sectors of a part of the market.

These indicators are used mainly by the stock markets of various countries and each of them can be integrated by companies with specific characteristics such as having a similar market capitalization or belonging to the same type of business, there are also some indices that only consider a handful of shares to determine their value or others that consider hundreds of shares.

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 investments in shares and shares of an entity. If investors are not confident, share prices tend to fall.

They also work to measure the performance of an asset manager and allow investors to make a comparison 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. carefully observed how the shares of the companies tended to rise or fall together in price, so he created two indices: one that contained the 20 most important railway companies (since it was the most important industry at the time), as well as 12 shares of other types of businesses

Currently in our economy there are various indices and they can partner based on their geography, sectors, company size or asset classFor example, the US Nasdaq index is made up of the 100 largest largely technology-related companies such as Apple (AAPL), Microsoft (MSFT), Amazon (AMZN), Facebook (FB), Alphabet (GOOG), Tesla (TSLA), Nvidia (NVDA), PayPal (PYPL), Comcast (CMCSA), Adobe (ADBE).

How is it calculated and how to read them?

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 title on the corresponding stock market by the total number of shares that are in circulation in the market.

Firms 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 examining its changes over time. Current indices always start with a fixed value based on stock prices on their start date, but not everyone follows this method. Therefore, it can lead to inaccuracies.

If one index gains 500 points in one day, while another only adds 20, it might appear that the former outperformed. However, if the former started the day at 30,000 points and the other at 300, it can be seen that, in percentage terms, the gains for the latter were more remarkable.
