A stock index is an indicator used to show the evolution of the value of a certain set of assetsfor which you need to have data from different companies or sectors of a part of the market.

These indicators are mainly used by the stock exchanges of various countries and each of them can be integrated by firms with specific characteristics such as having a similar market capitalization or belonging to the same industry, there are also some indices that only take into account a handful of shares to determine their value or others that consider hundreds of shares.

Stock market indices serve as indicator of stock market confidence, business confidence, health of the national and global economy, and stock investment performance and shares of an entity. Generally, if investors lack confidence, stock prices tend to fall.

Likewise, they function to measure the performance of an asset manager and allow investors to compare 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 the journalist Charles H. Dow. looked closely at how company shares tended to rise or fall in price together, so he created two indices: one that contained the 20 most important railway companies (as it was the most important industry at the time), as well as 12 shares of other types of businesses

Currently in our economy there are various indices and They can be associated based on their geography, 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).

Each stock index has its own calculation method, but the main component is the market capitalization of each firm that comprises it. This is obtained by multiplying the day's value of the share in the corresponding stock market by the total number of shares that are on the market.

Companies that are listed on the stock market are required to present a balance of its composition. Said report must be delivered every three or 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 sees an increase of 500 points in one day, while another only adds 20, it might appear that the first one performed better. But, 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 larger.
