The Sensex, India’s premier stock market index, is often seen as the pulse of the country’s economic and market trends. With a legacy dating back to 1986, the Sensex comprises 30 of the largest and most actively traded companies on the Bombay Stock Exchange (BSE).
For investors, understanding how the Sensex is calculated and its relationship with the Nifty value is crucial to making informed decisions. This guide unveils the secrets behind its calculation and highlights effective ways to invest in it.
What is the Sensex?
The Sensex stands for the Sensitive Index and reflects the performance of 30 well-established companies from various sectors. These companies are selected based on factors like market capitalisation, trading frequency, and industry representation. The index is widely recognised as a barometer of the Indian stock market and plays a pivotal role in shaping investment strategies.
How is the Sensex Calculated?
The Sensex is calculated using the free-float market capitalisation methodology. This approach takes into account the total market value of a company’s shares available for trading (free float) and adjusts it against a base value to derive the index.
1. Free-Float Market Capitalisation
The free-float market capitalisation is the total market value of a company’s publicly available shares. Restricted shares, such as those held by promoters, are excluded from the calculation.
2. Base Year And Value
The base year for the Sensex is 1978-79, and the base value is set at 100. This provides a reference point to compare current market performance.
3. Formula For Sensex Calculation
The formula for calculating the Sensex is:
Sensex = (Free-float Market Capitalisation of 30 Companies ÷ Base Market Capitalisation) × Base Value.
This formula ensures that the Sensex reflects real-time market trends, making it a reliable indicator of market performance.
Relationship Between Sensex And Nifty Value
The Sensex and Nifty value are two leading indicators of the Indian stock market, each representing a different stock exchange. While the Sensex tracks the BSE, the Nifty value represents the NSE through its flagship index, the Nifty 50.
Both indices employ the free-float market capitalisation methodology, but their composition and sectoral weightages differ. Monitoring both indices provides investors with a comprehensive view of market dynamics.
Ways To Invest In The Sensex
1. Index Funds
Index funds are mutual funds that replicate the performance of the Sensex. By investing in these funds, investors gain exposure to all 30 Sensex companies, ensuring diversification and minimising risk. Index funds are ideal for passive investors seeking long-term growth.
2. Exchange-Traded Funds (Etfs)
Sensex-based ETFs are traded on stock exchanges like regular shares. These funds closely track the Sensex’s performance, providing flexibility and liquidity. ETFs are suitable for investors who prefer real-time trading and lower expense ratios.
3. Direct Investment In Sensex Stocks
Investors can directly purchase shares of companies listed in the Sensex. This approach allows for customised portfolios but requires detailed research and monitoring.
4. Derivatives Trading
For experienced traders, derivatives such as futures and options based on the Sensex provide opportunities to profit from market volatility. However, these instruments carry higher risks and require expertise.
5. Systematic Investment Plans (SIPs)
SIPs in Sensex-based mutual funds enable investors to invest regularly in small amounts. This method leverages rupee-cost averaging, reducing the impact of market fluctuations.
