Stock market indices… what?

stock index It is an indicator that shows how the price of a certain set of assets changestherefore it collects data from different companies or sectors of the market.

These indicators are mainly used by the stock exchanges of different countries and businesses with specific requirements can integrate each such as having a similar market capitalization or belonging to the same industry, likewise, there are some indexes that consider only a handful of shares to determine their value or others that consider hundreds of shares.

Stock market indices act as an 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 entity shares. In general, if investors lack confidence, stock values ​​tend to fall.

They also work for the asset manager performance and allow comparisons between profitability and risk; the opportunities of measuring a financial asset or creating portfolios.

This type of indicators began to be used at the end of the 19th century after journalist Charles H. Dow. He looked carefully at how company stocks tended to go up or down together in price, so he created two indexes: one of the top 20 railroad companies (since it was the industry’s largest more at the time), as well as 12 acts of other types. of affairs

Today there are various indexes and they can also be grouped by geography, sectors, company size or asset typeFor example, the US Nasdaq index consists 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 it calculated and how to read them?

Each stock index has its own way of measuring it, but the main factor is the market capitalization of each company that integrates it. This is obtained by multiplying the day’s value of activity on the corresponding stock market by the total number of shares held by the investors.

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

To read a stock index one must also pay attention to its evolution over time. New indexes are always opened with a fixed value based on stock prices on your start date, but not everyone follows this method. Therefore, it can lead to failures.

If one index rises 500 points in a day, and another index only adds 20, it may appear that the first index has outperformed. But, if the first day started at 30,000 points and the next day at 300, it can be concluded that, in percentage terms, the gains were significant for the latter.
