How are Companies Selected for NIFTY Energy?

The selection of companies for the NIFTY Energy index is based on several criteria to ensure that only relevant and significant players in the energy sector are included. Here are the primary factors considered for inclusion:

Listing on NSE: Companies must be listed on the National Stock Exchange of India and already be a part of the NIFTY 500 index.

Sector Classification: The companies should be classified under the energy sector. This includes sub-sectors such as oil and gas, power generation, and renewable energy.

Market Capitalisation: Companies must meet specific market capitalization requirements to ensure they are significant players in the industry. Typically, the companies with larger market capitalisations are given preference.

Free-Float Market Capitalisation: The selection is often based on the free-float market capitalisation, which excludes shares held by promoters and other large shareholders, focusing on shares available for trading by the public.

Liquidity: The companies must have high liquidity, meaning their shares are actively traded on the NSE. This ensures that the stocks can be easily bought and sold without causing significant price fluctuations. The required trading frequency is at least 90% in the previous six months.

The selection process is periodically reviewed – twice each year – to ensure that the NIFTY Energy index accurately represents the sector. Companies that no longer meet the criteria may be removed, and new companies that meet the requirements may be added. This dynamic approach helps maintain the relevance and accuracy of the index.

How is the Value of NIFTY Energy Index Calculated?

The value of the NIFTY Energy index is calculated using a free-float market capitalisation-weighted method. This method ensures that the index reflects the market value of the constituent stocks while considering only the shares available for trading.

The formula used is:

NIFTY Energy Index =(Sum of Market Capitalisation of Constituent Stocks) / (Base Market Capitalisation) × (Base Index Value)

Free-Float Market Capitalisation: First, the free-float market capitalisation of each company in the NIFTY Energy index is determined. This is calculated by multiplying the company's share price by the number of shares available for trading.

Weight Assignment: Each company's weight in the index is based on its free-float market capitalisation relative to the total free-float market capitalisation of all the companies in the index. Companies with higher market capitalisations have a greater influence on the index’s value.

Index Calculation: The index value is then calculated by summing the free-float market capitalisations of all the companies in the index and dividing by a divisor. The divisor is a value that is adjusted to ensure continuity of the index value despite changes in the constituent stocks or other corporate actions.

Periodic Adjustments: The index is periodically reviewed and adjusted to reflect changes in the market capitalisation of the constituent companies, as well as any additions or deletions from the index. This ensures that the index remains an accurate representation of the sector.

Index Base Value: The NIFTY Energy index has a base date and base value, which serve as a reference point. The base value is typically set at a specific date with an arbitrary index level (e.g., 1000 points). The current index level indicates the change in market capitalisation relative to the base date.

By using this methodology, the NIFTY Energy index provides a comprehensive and accurate measure of the performance of the energy sector. It allows investors to track the sector’s overall performance and make informed investment decisions based on the index movements.
