What is BSE 500?
The BSE 500 Index is a broad market equity index comprising 500 companies listed on BSE (formerly Bombay Stock Exchange). It is designed to represent a large portion of the Indian listed equity market and includes companies from a wide range of industries.
The index is used by investors, analysts, fund managers, and researchers to track the performance of a broad group of listed companies as compared to indices that focus solely on a specific segment, such as large cap, mid cap or small cap companies.
History and origin of the BSE 500
The index was launched on August 9, 1999, with a base date is February 1, 1999, and a base value is 1,000.
Over time, the BSE 500 Index has become a widely used broad market benchmark because it includes companies across multiple sectors and market capitalisation segments.
How is the BSE 500 calculated?
The BSE 500 Index is calculated using something called the free-float market capitalisation method. Sounds technical, but it is simple. Companies that have a larger value of shares available for public trading usually get a bigger weight in the index. So, their stock price movements can have a bigger impact on how the index moves.
The BSE 500 is selected from the larger BSE 1000 universe. But not every company automatically gets in. A company must meet a few basic conditions, which include the following:
- It should rank among the top 750 companies based on annualised traded value.
- It should rank among the top 750 companies based on average free-float market capitalisation over the previous six months.
- It should have traded on at least 80% of the trading days during the six-month review period.
After this, the eligible companies are ranked based on their average daily total market capitalisation. The top companies are then selected so that the index has 500 stocks. Existing companies in the index may get some continuity during the review, while new eligible companies may be added if needed.
The index is reviewed from time to time so that it continues to represent a broad mix of listed companies in India, as per the prescribed index methodology.
Which companies are included in BSE 500?
The BSE 500 includes companies from a broad range of sectors, including financial services, consumer-oriented industries, industrials, energy, healthcare, information technology, and utilities.

Risks to consider before investing in BSE 500
Although a broad market index may reduce reliance on a limited number of companies compared with narrower benchmarks, it remains subject to equity market risks.
Some key risks include:
Market risk: Equity prices may decline because of factors such as economic slowdowns, earnings weakness, interest rate changes, global developments, or valuation adjustments.
Concentration risk: Although the index contains 500 companies, larger constituents continue to carry higher weights and may have a greater influence on overall index performance.
Sector-specific risk: Weakness in major sectors may affect the performance of the index.
Tracking error risk: Index funds and ETFs tracking the index may not perfectly replicate index returns because of expenses, cash holdings, portfolio rebalancing, and other operational factors.
Liquidity considerations: ETF investors may experience differences in trading liquidity depending on the product and prevailing market conditions.
