Nifty Infrastructure

What is the Nifty Infrastructure index?

The Nifty Infrastructure index is designed to track the performance of companies from the infrastructure sector, listed on the National Stock Exchange (NSE). It includes companies engaged in various infrastructure-related activities such as power, construction, transportation, oil & gas, telecommunications, and more. The index comprises 30 stocks that reflect the performance of key industries responsible for India’s physical and economic development. Infrastructure being a core sector in any economy, the index helps investors gauge the overall health and growth potential of infrastructure-related businesses in India.

Given the government's continued focus on infrastructure development through initiatives like Gati Shakti and National Infrastructure Pipeline (NIP), this index offers a thematic opportunity for long-term investors. The Nifty Infrastructure index serves as a performance benchmark for mutual funds and ETFs that focus on capital goods and utilities. It is well-suited for investors looking to capitalise on India’s urbanisation and industrialisation trends.

Nifty Infrastructure selection criteria

Stocks for the Nifty Infrastructure index are selected from the Nifty 500 universe. The selection is based on the average free-float market capitalisation and average daily turnover over a six-month period. Eligible stocks should belong to infrastructure-related sectors such as construction, power, telecom, transport services, and ports. The top 30 stocks that meet the eligibility criteria and show strong liquidity are selected. The index is reviewed semi-annually in March and September.

Companies must also have a minimum listing history and should not be under any suspension. The focus remains on representativeness and liquidity within the sector. This method ensures the inclusion of companies that are leaders in the infrastructure domain while maintaining investability. By filtering through various layers like sector, liquidity, and size, the index ensures that only prominent and stable companies are represented.

How is the Nifty Infrastructure index calculated?

The Nifty Infrastructure index is calculated using the free-float market capitalisation-weighted methodology. In this system, each stock’s weight is determined by its market capitalisation adjusted for promoter holdings and other non-publicly traded shares. The base date for the index is January 1, 2004, and the base value is set to 1000. Real-time index values are updated during trading hours using live prices. To ensure diversification, individual stock weights may be capped at the time of rebalancing. NSE Indices Ltd, a subsidiary of the NSE, manages and maintains the index. It is rebalanced semi-annually to reflect changes in the market and maintain the integrity of sector representation. The free-float methodology ensures that the index mirrors the actual investable portion of the market. It also helps prevent index distortion by companies with high promoter ownership but low public float.
