The Nifty 50 is a benchmark index comprising 50 large and actively traded companies listed on the NSE. It reflects the performance of major sectors of the Indian economy and is calculated using the free-float market capitalisation method, which considers only publicly tradable shares.
The index is based on prices as of November 3, 1995, with a base value of 1000. It includes 50 stocks and is reviewed and rebalanced twice every year. As of September 2025, the Nifty 50 represents around 54.10% of the total free-float market capitalisation of NSE-listed companies and contributes nearly 26.84% of the exchange’s total traded value over the previous six months.
The index is dominated by Financial Services with the highest weight, followed by Oil & Gas and Information Technology. It also includes significant exposure to Auto, FMCG, Telecom, Healthcare, Metals, Power and Construction, making it a broad representation of the Indian economy.
HDFC Bank holds the largest share in the index, followed by Reliance Industries and ICICI Bank. Other major contributors include Bharti Airtel, Infosys, Larsen & Toubro, SBI, ITC, Axis Bank and Mahindra & Mahindra.
On January 19, the Nifty 50 closed at 25,517.40, down 176.95 points or 0.69%. A total of 21 stocks advanced while 29 declined. The index traded between 25,496 and 25,653 during the session. Valuations stand at a P/E of 22.40 and P/B of 3.49. The 52-week range remains between 21,743 and 26,373.

The index has declined slightly in the short term, with negative returns over 1 week, 1 month and 3 months. However, it remains positive over longer periods, delivering gains over 6 months, 1 year, 3 years and 5 years.
Indigo led the rally with nearly 4% gains, followed by Tech Mahindra, Kotak Bank, Hindustan Unilever and Maruti Suzuki, driven by sector-specific buying.
Wipro saw the sharpest fall of over 6%, while ICICI Bank, Reliance Industries, Tata Motors DVR and Cipla also declined, pulling the index lower.
Despite the day’s decline, the Nifty 50 continues to be India’s most reliable benchmark, capturing broad market trends across leading sectors. While short-term volatility persists, its diversified nature and long-term growth track remain intact.
