What is a stock index and what is it for?

stock index it is an indicator that measures the evolution of the value of a certain set of assetstherefore it collects data from different companies or sectors of a part of the market.

These indicators are mainly used by the stock markets of different countries around the world and firms with different specialties can integrate each for example having a similar market capitalization or belonging to the same type of industry, also, there are some indexes that only take into account 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 company 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 indicator began to be used at the end of the 19th century after journalist Charles H. Dow. He looked closely at how company stocks tended to go up or down together in price, so he created two indexes: one containing the top 20 railroad companies (since it was the industry’s most more at the time), as well as 12 acts of other types of businesses.

Today in humanity there are various indices and they can be clustered based on 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 to read an index?

Each stock index has its own way of measuring it, but the main factor is the market capitalization of each firm that integrates it. This is obtained by multiplying the day’s value of the share in the corresponding stock market by the total number of shares in circulation in the market.

Listed companies are required to present a balance of its composition. That report must appear every three to six months, as appropriate.

Reading a stock index is all about paying attention to its changes over time. Current indices always start with a fixed value based on the prices of the securities on your start date, but not everyone follows this method. Therefore, it can lead to failures.

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, it follows that, in percentage terms, the gains for the latter were greater.
