A stock index is an indicator that measures how the price of a certain 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 the countries and each one of them can be integrated by companies with different specificities, such as having a similar market capitalization or belonging to the same business type. There are also some indices that only consider a handful of shares to determine its value or others that consider hundreds of shares.
Stock indices serve 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 stocks and shares of a company. Generally, if investors are not confident, stock values tend to fall.
Likewise, they 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 investigate 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
Today there are various indices and they can be grouped based on their location, sectors, company size or even the type of asset, for 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) .
Each stock index has its own way of being measured, 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 bond in the corresponding stock market by the total number of shares that are in the hands of investors.
Firms listed on the stock market are required to present a balance sheet of their composition. Said report must be disclosed every three or six months, as appropriate.
Reading a stock index also requires analyzing its variations over time. New indices always open with a fixed value based on the prices of the securities on their start date, but not all follow this method. Therefore, it can be misleading.
If one index grows 500 points in one day, while another only adds 20, it might appear that the former outperformed. However, if the first started the day at 30,000 points and the other at 300, it can be assumed that, in percentage terms, the gains for the second were more important.
