Sensex: A Guide To Achieving Your Goals

Sensex, short for the Sensitive Index, is a stock market index that serves as a benchmark for the performance of the Bombay Stock Exchange (BSE), one of the major stock exchanges in India. It is a market capitalization-weighted index that includes the BSE’s 30 largest and most regularly traded equities.

The Sensex launched on January 1, 1986, with a base value of 100 points.Since then, it has become one of the most widely tracked and reported indices in India and serves as a key indicator of the overall health and direction of the Indian stock market.

The calculation methodology of the Sensex takes into account the free-float market capitalization of the constituent stocks. The complete market value of a company’s shares that are accessible for trade in the market is referred to as free-float market capitalization. It excludes shares held by promoters, government entities, and strategic investors that are not available for regular trading.

The stocks included in the Sensex represent various sectors of the Indian economy, such as banking, information technology, manufacturing, energy, and consumer goods. The composition of the index is periodically reviewed to ensure that it reflects the changing market dynamics and represents the most influential and actively traded companies.

The movement of the Sensex is influenced by various factors, including domestic and international economic developments, corporate earnings, government policies, interest rates, and global market trends. Investors and market participants closely monitor the Sensex as an indicator of market sentiment and to make investment decisions.

The Sensex is widely regarded as a barometer of the Indian stock market’s performance and is used by investors, financial institutions, and analysts to assess the overall direction and trends in the market. It serves as a reference point for measuring the performance of mutual funds, portfolio returns, and comparing the performance of individual stocks against the broader market.

It’s important to note that the Sensex is just one of the many stock market indices in India, and there are other indices like Nifty 50, Nifty Bank, and sector-specific indices that provide additional insights into specific segments of the market.
