Nifty Oil & Gas

The NIFTY Oil & Gas share price is computed by weighting its 15 stocks on the basis of periodically capped free-float market capitalization relative to a base market capitalization value on a real-time basis. 

In order to be considered for inclusion in the NIFTY Oil & Gas index, the securities must fulfill the following eligibility criteria:

1. Should be listed on the National Stock Exchange.
2. Should form a part of NIFTY 500.
3. Should be a part of the oil, gas & petroleum industry.
4. If the number of eligible stocks falls below 10, then in such cases, the deficit number of stocks shall be selected from the universe of top 800 ranked stocks based on both average daily turnover and average daily full market capitalization data of the previous six months from NIFTY 500’s universe.
5. Should have a trading frequency of at least 90% in the past six months.
6. Must have a listing history of at least six months.
7. New securities will be included, if their float-adjusted market capitalization is at least 1.5 times of the index’s smallest constituent’s free-float market capitalization.
8. A recently listed company (IPO) can be included if it meets the above eligibility criteria for a period of three months instead of six months.
9. Should adhere to the cap of 33% in case of a single stock and 62% for the top 3 stocks cumulatively at the time of rebalancing.

The index value is calculated as follows – 

    Index Value = Current Index Market Capitalization/ (Base Free Float Market Capitalization * Base Index Value)
