Introduction to Sensex — BSE Sensitive Index
The Sensex, widely regarded as the benchmark stock market index of India, is a vital component of the country's financial landscape. Launched in 1989 by the Bombay Stock Exchange (BSE), the Sensex is a 30-stock index that represents the performance of the Indian equity market. As a financial analyst, understanding the dynamics of the Sensex is crucial for making informed investment decisions. In this article, we will delve into the intricacies of the Sensex, its history, methodology, and significance in the Indian stock market.
History and Evolution of Sensex
The first Sensex was launched on April 23, 1989, with a base value of 100. Initially, it consisted of 30 stocks from various sectors, including energy, finance, consumer goods, and more. The index was designed to track the performance of the Indian equity market and provide a benchmark for investors to gauge their portfolio's performance.
Over the years, the Sensex has undergone several changes. In 1995, the BSE introduced the Sensex Sectoral Indices, which categorized stocks into different sectors. This allowed investors to track the performance of specific sectors and make more informed investment decisions. In 2003, the BSE launched the Sensex Futures, a derivative product that allows investors to trade on the future value of the Sensex.
Methodology of Sensex Calculation
The Sensex is calculated using a market capitalization-weighted method, where the stocks are weighted based on their market capitalization. The calculation involves the following steps:
- Stock selection: The BSE selects 30 stocks from various sectors based on their market capitalization, liquidity, and other factors.
- Market capitalization: The market capitalization of each stock is calculated by multiplying the number of outstanding shares by the stock price.
- Weighting: The stocks are weighted based on their market capitalization, with the largest market capitalization stocks receiving the highest weightage.
- Calculation: The Sensex is calculated by taking the weighted average of the stock prices.

Deep-Dive into Strategy
The Sensex is calculated using a market capitalization-weighted method, which means that the stocks with the largest market capitalization receive the highest weightage. This can lead to a concentration of weightage in a few large-cap stocks, which can be beneficial for investors who want to track the performance of these stocks.
However, this concentration of weightage can also lead to a lack of representation of smaller-cap stocks, which can be beneficial for investors who want to track the performance of these stocks. To address this issue, the BSE has introduced the S&P BSE SmallCap Index, which tracks the performance of smaller-cap stocks.
