Stock indices… What for?

a stock index It is an indicator that measures how the price of a set of assets evolves.so it takes data from various companies or sectors of a fragment of the market.

These indicators are used mainly by the stock markets of various nations and each of them can be integrated by firms with specific characteristics such as having a similar market capitalization or belonging to the same business type, likewise, 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 indices serve as indicator of confidence in the stock market, business confidence, the health of the national and global economy, and the performance of stock investments and shares of an entity. If investors are not confident, share prices will 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. To carefully analyze how the shares of companies tended to rise or fall together in price, he created two indices: one that contained the 20 largest railway companies (as it was the most important industry at the time), as well as 12 shares of other types of businesses

Currently there are various indices and They can partner based on their geographic location, industries, company size, or even asset classFor 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 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 firm that integrates it. This is obtained by multiplying the daily value of the share in the corresponding stock market by the total number of shares that are in the market.

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

Reading a stock index also implies 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, it can lead to failures.

If one index grows 500 points in one day, while another only gets 20, it might appear that the former performed better. But, if the former started the day at 30,000 points and the other at 300, you can see that, in percentage terms, the gains for the latter were considerable.
