The Bombay Stock Exchange (BSE) was established in 1875 and is one of Asia's fastest stock exchanges. It has over 5,000 listed companies from various industries, with a total market capitalization of over $1.5 trillion. BSE provides an efficient market for trading equities, debt instruments, derivatives, and mutual funds. Two important indices tracked on BSE are the SENSEX, which tracks the performance of 30 major companies, and the BSE National Index. These indices are important indicators of how the overall stock market is performing.

4. SENSEX and The BSE NATIONAL INDEX:
The two critical indices
• The S&P BSE SENSEX (S&P Bombay Stock Exchange Sensitive Index), also-called the BSE 30 or simply the SENSEX
• Is a free-float market-weighted stock market index of 30 well-established and financially sound companies listed
on Bombay Stock Exchange.
• The 30 component companies which are some of the largest and most actively traded stocks, are representative of
various industrial sectors of the Indian economy.
• Regarded as the pulse of the domestic stock markets in India.
• The base value of the S&P BSE SENSEX is taken as 100 on 1 April 1979, and its base year as 1978–79.

5. • The launch of SENSEX in 1986 was later followed up in January 1989 by introduction of BSE NATIONAL INDEX
(Base: 1983-84 = 100)
• It comprised 100 stocks listed at five major stock exchanges in India - Mumbai, Calcutta,
Delhi, Ahmedabad and Madras.
• The BSE National Index was renamed BSE-100 Index from 14 October 1996 and, since then, its calculations
take into consideration only the prices of stocks listed at BSE.

6. Working of the BSE
• BSE disseminates information on the Price-Earnings Ratio, the Price to Book Value Ratio, and the Dividend Yield
Percentage of all its major indices on day-to-day basis.
• The values of all BSE indices are updated on a real time basis during market hours and displayed through the BOLT
system, the BSE website, and news wire agencies.
• All BSE Indices are reviewed periodically by the BSE Index Committee.
• This Committee, which comprises eminent independent finance professionals, frames the broad policy guidelines for
the development and maintenance of all BSE indices. The BSE Index Cell carries out the day-to-day maintenance of all
indices and conducts research on development of new indices.
• Bolt: This automated, screen-based trading platform called BSE On-line trading (BOLT) had a capacity of 8 million
orders per day

8. Sensitive Index
• How the value of the “BSE Sensex” or “sensitive index” is calculated?
• The Sensex has a very important function. The Sensex is supposed to be an indicator of the stocks in the BSE.
• It is supposed to show whether the stocks are generally going up, or generally going down.
• To show this accurately, the Sensex is calculated taking into consideration stock prices of 30 different BSE
listed companies.
• It is calculated using the “free-float market capitalization” method.
• This is a world wide accepted method as one of the best methods for calculating a stock market index.

9. Market Capitalization
• Market cap or market capitalization is simply the worth of a company in terms of it’s shares! To put it in a
simple way, if you were to buy all the shares of a particular company, what is the amount you would have to
pay? That amount is called the “market capitalization”!
• To calculate the market cap of a particular company, simply multiply the “current share price” by the
“number of shares issued by the company”!
i.e, Market cap of company ‘X’ = (current share price) x (no. of issued shares by company X)
• Depending on the value of the market cap, the company will either be a “mid-cap” or “large-cap” or “small-cap”
company!

10. According the BSE, any shares that DO NOT fall under the following criteria, can be considered to be open
market shares:
• Holdings by founders/directors/ acquirers which has control element
• Holdings by persons/ bodies with "controlling interest"
• Government holding as promoter/acquirer
• Holdings through the FDI Route
• Strategic stakes by private corporate bodies/ individuals
• Equity held by associate/group companies (cross-holdings)
• Equity held by employee welfare trusts
• Locked-in shares and shares which would not be sold in the open market in normal course.

11. Free-Float market cap
• Many different types of investors hold the shares of a company! The Govt. may hold some of the shares.
Some of the shares may be held by the “founders” or “directors” of the company. Some of the shares may be
held by the FDI’s etc.
• Now, only the “open market” shares that are free for trading by anyone, are called the “free-float” shares.
When we are calculating the Sensex, we are interested in these “free-float” shares.
• A simple way to understand the “free-float market cap” would be, the total cost of buying all the shares in
the open market!

12. Calculation of free-float Market Cap
• First: Find out the “free-float market cap” of all the 30 companies that make up the Sensex!
• Second: Add all the “free-float market cap’s” of all the 30 companies!
• Third: Make all this relative to the Sensex base. The value you get is the Sensex value!
Example:
• Suppose, for a “free-float market cap” of Rs.100,000 Cr... the Sensex value is 4000…
• Then, for a “free-float market cap” of Rs.150,000 Cr... the Sensex value will be..
• So, the Sensex value will be 6000 if the “free-float market cap” comes to Rs.150,000 Cr!
Please Note: Every time one of the 30 companies has a “stock split” or a "bonus" etc. appropriate changes
are made in the “market cap” calculations.

13. Why 30 Companies?
• Now, there is only one question left to be answered, which 30 companies, why those 30 companies, why no
other companies?
• The 30 companies that make up the Sensex are selected and reviewed from time to time by an “index
committee”.
• This “index committee” is made up of:
• Academicians
• Mutual fund managers
• Finance journalists
• Independent governing board members
• Other participants in the financial markets.

14. Main criteria for selecting the 30 stocks
• Market capitalization: The company should have a market capitalization in the Top 100 market
capitalization’s of the BSE. Also the market capitalization of each company should be more than 0.5% of the
total market capitalization of the Index.
• Trading frequency: The company to be included should have been traded on each and every trading day for
the last one year. Exceptions can be made for extreme reasons like share suspension etc.
• Number of trades: The scrip should be among the top 150 companies listed by average number of trades
per day for the last one year.
• Industry representation: The companies should be leaders in their industry group.
• Listed history: The companies should have a listing history of at least one year on BSE.
• Track record: In the opinion of the index committee, the company should have an acceptable track record.
