What is the NIFTY Infrastructure?

NIFTY Infrastructure is a popular thematic index in India. It is an index on the National Stock Exchange (NSE), which operates the entire range of indices. The index value can help you understand the overall performance of the infrastructure sector in India. It denotes the performance of the infrastructure sector in real time. It consists of 30 constituents, which are the top infra companies in India.

The index consists of 30 public companies listed on the NSE. These companies belong to Railways, Roads, Telecom, Power, and other sub-sectors forming the infrastructure industry. Some companies forming the index are ACC, Adani Ports, Ambuja Cements, Apollo Hospitals, Ashok Leyland, Bharti Airtel, and GAIL. Launched on the 7th of August 2007, it has become one of India’s most trusted thematic indices. The index’s base date and base value are 1st of January 2004 and 1000, respectively.

Every constituent in the index has a weightage. However, some companies or sub-sectors might have more weightage than others in it. Based on their weightage, each stock contributes to its value. The index is reconstituted semi-annually by the concerned parties. BOD of NSE Indices, the Index Advisory Committee, and the Index Maintenance Sub-Committee are responsible for managing it for investors.

How is NIFTY Infrastructure Calculated?

The index consists of 30 stocks belonging to 11 different sectors. You already know that each stock has a weightage in the index’s total value. Stocks are weighted based on the capped free-float market cap. Also, the free-float market cap is measured relative to the base market cap. Before we get to the formula, you must know that there are certain conditions for stocks to be included in it. For instance, a stock should be listed on the NSE and part of the NIFTY 500 . Stocks that do not fulfil the conditions might be removed from the index after some time.

You can calculate the NIFTY Infrastructure index value with this formula:

NIFTY Infrastructure Index Value = Real-time index market cap / (base free float market cap * 1000)

In the above formula, you can get the real-time index market cap by finding the product between outstanding shares, capping factor, share price, and IWF (Investable Weight Factors).

How are Stocks Selected for Inclusion in NIFTY Infrastructure?

As discussed above, stocks must fulfil certain criteria to be included in the index. However, there might be a case where the eligible stocks for the stocks go below ten. In such a case, the top-ranked stocks based on daily turnover and full market cap are selected. Another condition for inclusion is that the company must belong to the infrastructure sector in India.

Constituents of the NIFTY Infrastructure index must have a trading frequency of 90% or more in the past six months. Also, the company must have a listing history of at least six months for inclusion. Usually, the eligibility criteria for different stocks are checked for six months. However, the period might decrease to three months for a newly-listed company in the infrastructure sector. Also, the weightage of a single stock in the index cannot go beyond 20%.

How to Invest in NIFTY Infrastructure?

It is crucial to note that this thematic index is not a financial instrument. It tracks the performance of the top infra companies in India. For the same rationale, you cannot directly invest in this index or any index. Most investors use it to perform investment research in the infrastructure sector. However, you can find financial instruments attached to it.

Investors can find mutual fund schemes and Exchange Traded Funds (ETFs) that track their performance. You can also find exchange-traded derivatives based on its value. FUTIDX DIX and OPTIDX are some popular derivatives with their value as the underlying asset. You can also purchase individual stocks and try to replicate their performance in your portfolio.
