What is Sensex and Nifty in simple words?
What is Sensex and Nifty?

What is Index? Definition of Index is “An Index is a statistical aggregate that measures change.” Remember this throughout this post – ‘statistical aggregate’. All Index are not same – they can be differentiated based on countries, the market cap of stocks they cover or even how any stock will become part of Index. Sometimes I feel even construction of an index is an art & not science Sensex & Nifty both are large cap Index but from different stock exchanges BSE NSE.

What is Sensex?

Full Form of Sensex is Sensitive Index. People are happy when the Sensex goes up and upset when it goes down. Sensex is the stock market index of the Bombay Stock Exchange or BSE – it is also called BSE Sensex.

Sensex Meaning

It is the market weighted stock index of 30 companies that are selected on the basis of financial soundness and performance. Usually, large and well-established companies that are are representatives of the various industrial sectors are chosen.

It was first published in 1986. The base value of Sensex is 100 and the base year is 1978-79.

Let us look at some numbers.

The number of stocks in the Sensex – 30

As of March 15, 2017, the Full Market capitalization of Sensex is 4,986,299 crores and the free float market capitalization is Rs. 2,687,777 crores.

How Sensex is calculated?

The Sensex is calculated using the Free-float Market Capitalization’ method. In this method, the index reflects the free-float market value of the 30 constituent stocks relative to a base period.

What is meant by free float market capitalization?

Free float stands for the shares that are open for trading. All shares may not be free floating. Some may be pledged, some may be in the hands of the persons or bodies having controlling interest/promoters, some shares may be government holdings etc. Such locked-in shares are not considered free floating.

What is Market capitalization?

Market capitalization is the combined worth of all the stocks of different companies within the stock exchange.

The market capitalization of a company is arrived at by the product of the price of its stock and number of shares issued by the company.

This figure is multiplied by the free-float factor to determine the free-float market capitalization. The free float factor is derived from the information each company submits regarding the free floating shares. Every company has to give the information on a quarterly basis in a format given by BSE.

The free float market capitalization of all companies is summed up.

The free float market capitalisation is then divided by an index divisor to get the Sensex value. This divisor adjusts for changes in stocks and other corporate actions. The divisor is the value of the Sensex Index in the base year.

How Sensex Works – example

Suppose the index has two companies – X and Y.

Company X has 500 shares out of which 300 are free floating or available for general public to buy and sell. The price of each share is Rs.80.

Company Y has 1000 shares out of which 700 are free floating. The price of each share is Rs. 100

Market capital of Company X = 40000

Market capital of Company Y = 100000

Free-float factor for Company X = 0.60

Free-float factor for Company Y = 0.70

Total free float market capital of the index = (40000*0.60) + (100000*0.70) = 94000

Let us assume the base year index was 5000.

Value of Index = (94000 x 100)/5000 = 1880

So the Value of the Index is 1880.

The Same example can be applied to how nifty works.

What are the Highs and Lows of Sensex in last 10 years?

The market is affected by various political, social and economic factors across the world. The lowest points were reached in 2008 when the stock markets in U.S. started crashing and there were major credit losses in the U.S. There was a steep drop in 2015 as well.
