BT 500:
METHODOLOGY
How We Did It
It wasn't rocket science, but pure
arithmetic that we used.
The first
thing you would notice about the BT-500 tables this time is that they are
smaller than their predecessors of the past eight years. Company data,
traditionally presented in a double-spread, has been tightened to fit in
one page. Also, there is no BT-500 Directory.
There's a reason behind the changes: while
we wanted to give the numbers-hungry a comprehensive listing of India's
500 most valuable companies, we did not want to short-change our other
readers. Therefore, you would find most of our regular sections
intact-albeit thinner.
In all other aspects, there's no change in
the way we created this database. 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 Bombay Stock Exchange (BSE).
In terms of exclusions, companies owned by
the state-Central or states-owned public sector companies, banks, and
financial institutions-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, 1999, and March 31, 2000.
Our Methodology
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 capitalization 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
each company on sales and net profits |
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, 1999, and March 31, 2000. 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, 1999, and March 31, 2000, 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,
2000. 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.
Equity: The paid-up shareholder
capital.
Market Capitalisation: The average
market value between April 1, 1999, and March, 31, 2000. In addition, the
market capitalisation on March 31, 2000 has been presented alongside.
All the data for this research project was
provided by the CMIE, and analysed by Team BT.
