What is a stock index and what is it for?

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

These indicators are mainly used by the stock exchanges of countries and companies with different specialties can integrate each for example having a similar market capitalization or belonging to the same type of 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, share prices tend to fall.

They also work for the asset manager performance and enable investors to compare 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 carefully researched how company stocks tended to go up or down in price together, so he created two indexes: one of the top 20 railroad companies (the largest industry there at the time), as well as 12 acts of other types of businesses.

Today there are various indexes and they can 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 a stock index measured?

Each stock index has its own calculation method, but the main component is the market capitalization of each firm 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 on the market.

Businesses listed on the stock exchange are required to present a balance of its composition. That report must be published every three to six months, as appropriate.

Reading a stock index also involves observing its changes over time. New 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 misleading.

If one index grows 500 points per day, while another index only gains 20, it may appear that the first index performed better. However, if the first day started at 30,000 points and the next day at 300, you can see that, in percentage terms, the gains were significant for the latter.
