What is the BSE SENSEX Index?
The BSE SENSEX Index is a benchmark index of the Bombay Stock Exchange (BSE), representing the 30 largest and most actively traded companies in India. Introduced in 1986, the index reflects the overall performance of the stock market and serves as an indicator of the economic health of the country. The BSE SENSEX includes companies from various sectors, such as banking, IT, energy, and FMCG, providing a comprehensive snapshot of market sentiment. Calculated based on a free-float market capitalization method, the index tracks price movements of its constituent stocks in real-time, offering investors insights into market trends. A key metric for both domestic and international investors, the BSE SENSEX Index plays a vital role in portfolio management and decision-making in India’s financial markets.
How is the BSE SENSEX Index Value Calculated?
Calculation of the BSE SENSEX Index involves use of the free-float market capitalization method, reflecting market dynamics by excluding locked-in shares. It consists of 30 companies from various sectors, representing India's economy. The index value is determined by multiplying each company's free-float market capitalization by a price-weighted divisor, which is periodically adjusted to account for stock splits, dividends, or rights issues, ensuring consistency.
To compute the value of the BSE SENSEX, the following formula is applied:
SENSEX = (Index Divisor ∑ (Free-Float Market Capitalization of 30 Companies))
This formula ensures that only the actively traded shares influence the index value, providing a transparent and accurate reflection of market trends. The BSE SENSEX Index serves as a key benchmark for investors and analysts to gauge the overall performance of the Indian stock market.
