BSE Top 100 Companies
The S&P BSE 100 is a price-sensitive stock index designed to measure the performance of stocks of the top 100 most liquid companies listed on the Bombay Stock Exchange (BSE).
The stocks forming part of S&P BSE 100 belong to S&P BSE's Large to MidCap category.
The BSE 100 index is calculated in Indian Rupees. The index consists of float-adjusted stocks (float-adjusted means considering only shares available for investors and not held by other companies or the government). The S&P BSE 100 index was launched in January 1989, but the base year for BSE 100 is taken as the financial year 1983-84, with a base value of 100 points.
The list of BSE 100 companies is revised semi-annually in December and June every year. The BSE 100 companies are selected based on the following criteria-
- The constituent (i.e., company) should be a member of S&P BSE LargeMidCap
- The selection is based on the free-float market cap
- The weightage of the companies is based on the constituent's float-adjusted market capitalization
- The company should have a minimum annualized traded value of greater than or equal to 10 billion. Here, annualizing means converting a value from a short-term calculation or rate to an annual rate.
- The BSE 100 companies are selected based on their rankings. The list is obtained as a combination of their liquidity and market capitalization.
