With the arrival of the new year, comes the fun, enthusiasm, and resolution. It is surveyed that about 64% of the population gets the gym membership and oaths to stay motivated and healthy throughout the year.
This becomes very common and appreciated. Do you wonder how this estimation of such surveys is made? Do you think is it possible to gather the choice of interest of the entire population easily? It is quite a time-taking and confusing at the same time.
The technique that they use is Sampling, It is a method of statistical analysis in which a predetermined number of observations are taken from a larger population.
I understand it is confusing and boring. How is Sampling related to the stock market? I am pretty sure you have heard of Sensex and Nifty. They are related to sampling in the stock market.
There are millions of companies registered and double the millions of stock, so keeping a record of stock performance and data is quite troublesome. For that, a sample of stock is taken to represent the performance of the whole stock.
This method of sampling for the stock market record is Index. The value of the same is calculated by the stock price as per the sampling.
What Is An Index?
Stock Index or Stock Market Index, is the statistical measurement of changes taking place in the stock market. Certain stocks are stacked taking similar securities listed in the stock exchange this way it is created. The size of the company, their market capitalization, or type of industry is the criteria of selection.
Fluctuation of the prices of the securities underlying gives the index value overall. Index and prices are dependent on each other, if the price goes high, the index gets too. Similarly, if the price is down, the index gets down too.

On the other hand, if the stock is lower then indices become underperformed.
This results in the stock market giving the performance and idea of how to invest according to the curve. Passive investment, that investing in a portfolio in securities that resembles closely the index also gets through this stock indices. This helps to cut down expenditure in research and selection of equities with the help of passive investment.
