The stock market is a crucial component of any economy as it provides investors with a platform to buy and sell securities. One of the most popular stock market indices in India is the S&P BSE Sensex or simply, the Sensex. In this article, we will discuss what Sensex is and how it works.
What is Sensex?
The Sensex is a stock market index that is composed of the 30 largest and most actively traded companies listed on the Bombay Stock Exchange (BSE). The index was introduced on January 1, 1986, and is maintained and operated by Asia Index Pvt. Ltd, a joint venture between S&P Dow Jones Indices LLC and BSE.
How does Sensex work?
The Sensex is a market capitalization-weighted index, which means that the weightage of each company in the index is based on its market capitalization. Market capitalization is calculated by multiplying the total number of shares outstanding of a company with its current stock price.
To calculate the Sensex, the total market capitalization of the 30 companies is first calculated. This is then divided by a number called the "divisor" to arrive at the index value. The divisor is a number that is adjusted periodically to maintain continuity in the index value.

The Sensex is calculated in real-time and is updated every second. The index value reflects the overall performance of the 30 companies in the index. If the index value goes up, it means that the share prices of the companies in the index have increased. Similarly, if the index value goes down, it means that the share prices of the companies in the index have decreased.
Why is Sensex important?
The Sensex is an important indicator of the performance of the Indian stock market. It is widely used by investors, analysts, and researchers to gauge the health of the Indian economy. A rising Sensex indicates a bullish sentiment in the market, which means that investors are optimistic about the future prospects of the Indian economy. On the other hand, a falling Sensex indicates a bearish sentiment in the market, which means that investors are pessimistic about the future prospects of the Indian economy.
In conclusion, the Sensex is an important tool for investors and analysts to monitor the performance of the Indian stock market. It is a market capitalization-weighted index that reflects the performance of the 30 largest and most actively traded companies listed on the BSE. The index is calculated in real-time and is updated every second, providing investors with up-to-date information about the market.
