The BSE SENSEX, officially known as the S&P BSE SENSEX, is a benchmark stock market index of the Bombay Stock Exchange (BSE) in India. Established in 1986, it is one of the oldest stock indices in the country and serves as a barometer for the Indian equity market. The index comprises 30 of the largest and most actively traded companies across various sectors, reflecting the overall performance and health of the Indian economy.
What is SENSEX?
The term SENSEX is a portmanteau of "Sensitive Index." It represents a free-float market capitalization-weighted index that tracks the performance of 30 financially sound and well-established companies listed on the BSE. These companies are often referred to as "blue-chip" firms due to their large market capitalization, liquidity, and significant contribution to the economy.
Why Does SENSEX Matter?
The SENSEX holds significant importance for several reasons:
- Economic Indicator: It acts as a barometer of the Indian economy, providing insights into the market's overall direction. A rising SENSEX indicates investor confidence and economic growth, while a declining SENSEX may signal economic downturns.
- Investor Benchmark: Investors use the SENSEX as a benchmark to evaluate the performance of their investments. Mutual funds and portfolio managers often compare their returns against the SENSEX to assess their performance.
- Market Sentiment: Movements in the SENSEX reflect investor sentiment and can influence spending and investment decisions. Positive trends may boost consumer confidence, leading to increased economic activity.
How is SENSEX Calculated?
The SENSEX is calculated using the free-float market capitalization methodology, which considers only the shares readily available for trading in the market, excluding promoter-held and other locked-in shares.
Calculation Formula:
SENSEX=(∑(Free-float Market Capitalization of 30 Companies)Index Divisor)SENSEX=(Index Divisor∑(Free-float Market Capitalization of 30 Companies))
Key Components:
- Free-float Market Capitalization: This represents the market value of a company's shares that are available for trading by the public.
- Index Divisor: A predetermined figure used to maintain continuity and consistency of the index value over time, adjusting for corporate actions like stock splits or dividends.
This methodology ensures that the index reflects the market dynamics by giving more weight to companies with higher free-float market capitalization.
