Table of content

What is the Full Form of SENSEX?

SENSEX is an abbreviation for the Stock Exchange Sensitive Index. This widely recognized term is crucial in the Indian financial landscape, serving as a benchmark index for the Bombay Stock Exchange (BSE), one of the oldest and most prominent stock exchanges in Asia.

What is Stock Exchange Sensitive Index?

The Stock Exchange Sensitive Index, commonly known as SENSEX, is a free-float market-weighted index that represents the performance of 30 well-established and financially sound companies listed on the Bombay Stock Exchange. These companies, often referred to as blue-chip companies, are leaders in their respective industries and serve as a barometer for the Indian economy's health and performance.

Origin and Development of SENSEX

SENSEX was first introduced on January 1, 1986, with a base value of 100 points. Over the years, it has evolved to become the most widely tracked Indian equity index. The index's composition is reviewed semi-annually to ensure it accurately reflects the current market conditions and economic landscape.

How does SENSEX work?

SENSEX operates as a weighted average of its 30 constituent stocks. The weightage of each company in the index is determined by its free-float market capitalization. This means that companies with higher market values and more freely tradable shares have a greater impact on the index's movement.

The index is calculated in real-time during market hours, providing investors with a snapshot of the overall market sentiment. A rise in the SENSEX indicates a bullish trend in the market, while a fall suggests bearish sentiment.
