What is a stock index and what is it for?
a stock index is an indicator that shows how the value of a given set of assets evolves so you need to have data from different companies or sectors of a market fragment.
These indicators are mainly used 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 type of business, likewise, there are some indices that only consider a handful of shares to determine their value or others that consider hundreds of shares.
Stock market 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 company shares. Generally, if investors lack confidence, equity costs will tend to fall.
They also work to measure the performance of an asset manager and they allow to be able to compare between profitability and risk; measure the opportunities of a financial asset or create portfolios.
This type of indicators began to be used at the end of the 19th century after journalist Charles H. Dow. carefully researched how company stocks tended to go up or down in price together, so he created two indices: one containing the top 20 railroad companies (it was the biggest industry at the time), as well as 12 actions of other types of businesses
Currently in our economy there are various indices and they can be grouped according to their location, sectors, company size or even the type of assetFor example, the US Nasdaq index is made up of the 100 largest companies largely 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 company that integrates it. This is obtained by multiplying the value of the day of the share in the corresponding stock market by the total number of shares that are in circulation in the market.
Companies listed on the stock exchange are required to present a balance of its composition. This report must be notified every three or six months, as appropriate.
Reading a stock index also implies observing its changes over time. Current indices always start with a fixed value based on stock prices on your start date, but not everyone follows this method. Therefore, it can lead to inaccuracies.
If one index adds 500 points in a day, while another only achieves 20, it might seem that the first index performed better. However, if the former started the day at 30,000 points and the other at 300, it can be deduced that, in percentage terms, the gains for the latter were more remarkable.
