How
We Did It
The math behind the most comprehensive
update on Indian companies.
Chances are, this is the first
comprehensive update on the Indian market you'll be reading since the
world started talking in a different tongue after that fateful morning of
September 11, 2001. A reason why we decided to take another
parameter-average market capitalisation of the top 500 companies between
the period April 1-September 15, 2001.
How
We Crunched The Numbers |
»
Began with a universe of 4,894 companies
»
Separated public sector units from private
companies
»
Eliminated stocks that traded for less than
20% of 251 traded days
»
Computed the daily market capitalisation of
each company
»
Aggregated the daily market capitalisation
of each company
»
Divided the aggregate by the number of days
the scrip was traded
»
Ranked the 500 most valuable companies by
market capitalisation
»
Ranked the 500 according to marketcap for
two more time-frames
»
Ranked each company on sales and net
profits
»
Calculated the change in sales and
net profits over the previous fiscal |
In all other aspects, there's no change in
the way we created this database, except that we dropped equity capital
from the list and brought in one more parameter, the average market
capitalisation for 1999-2000. Since we strive for value all the time-like
our toppers whom you'd see in the list-we decided to rank the companies on
the two aforementioned parameters too. That means three sets of ranking on
three platforms of time. Giving you an idea of yesterday, today, and a
little bit of tomorrow.
Once again, it was the Mumbai-based Centre
for Monitoring Indian Economy (CMIE) to whom we entrusted the arduous task
of crunching megabytes of data. CMIE began with a universe of 4,894
companies selected on the basis of their average market capitalisation on
the BSE.
In terms of exclusions, companies owned by
the state-state-owned public sector companies, banks, and financial
institutions (FI)-were omitted from the sample unless the government's
equity stake in them had fallen to at most 50 per cent last year. Instead,
they were analysed in a separate study, The Most Valuable PSUs.
Eventually, our master sample constituted the 1,350 companies that traded
for at least seven days between April 1, 2000, and March 31, 2001.
Our Methodology
Ever since the year before last, the BT-500
listing has been drawn up based on each company's market value all through
the financial year-and not just on March 31. To compute that, each
company's market capitalisation was calculated on each trading day between
April 1, 2000, and March 31, 2001. Those values were aggregated and
divided by the number of days on which the scrip actually traded. This
yielded the company's average market value for the year.
Companies that were thinly traded had to be
eliminated. Since the BSE was open for trading on 251 days between April
1, 2000, and March 31, 2001, all those companies whose stocks traded for
fewer than a minimum of 20 per cent of the total number of trading days-or
51 days-were excluded from the study. To facilitate comparison, the
accounting period was standardised as the financial year ended March 31,
2001. In the case of companies whose accounting years ended on any other
dates-say, December 31-the figures for the latest financial year for which
results were declared were used. Sales and profit figures are annualised.
Our Definitions
All the definitions used in the computation
and the presentation of BT-500 are standard.
SALES: Operating Sales plus Other
Income and Excise.
NET PROFITS: Profits After Tax,
Interest, and Depreciation.
EARNINGS PER SHARE (EPS): Net profits
divided by the number of equity shares.
MARKET CAPITALISATION: The average
market value between April 1, 2000, and March, 31, 2001. In addition, the
market capitalisation on March 31, 2001, and the average market
capitalisation for the period between April 1, 2000, and September 15,
2001 have been presented alongside.
All the data for this research project was
provided by the CMIE, and analysed by Team BT.
