FINNIFTY, or the Nifty Financial Services Index, is a vital barometer for India's financial sector. It tracks the performance of the 20 largest companies in the country. Get more details here!

Introduction to FINNIFTY

In January 2021, the National Stock Exchange (NSE) launched Nifty Financial Services Index. FINNIFTY is the symbol for Nifty Financial Services Index in the stock market.  It is an index that includes the stock values of various companies that are part of the Indian financial sector. 

Although banks constitute well over 65% of the index, there are other major financial institutions in the list of component stocks as well. This includes insurance companies, housing finance, NBFCs and other companies that offer financial services. 

FINNIFTY, in a way, tracks the performance of such companies or subsectors within the economy in one single index. Therefore, if the financial sector of India is doing well in terms of finances and investor confidence, then FINNIFTY will probably gain in value and vice versa.

Given this diversification, FINNIFTY is attractive as a benchmark for trading and investing. 

Read on to learn more about the FINNIFTY index in detail, why you should invest and how to go about it.

FINNIFTY at a Glance

  5. FINNIFTY is reconstituted on a semi-annual basis.
  6. In order to reduce turnover, a buffer is applied based on free-float market capitalisation, which also determines each stock’s weightage.
  7. The weight of each stock in the index depends on its free float capitalisation value in the market. 

An easy way to understand free float market cap is: 

Free-float market capitalisation = Shares outstanding x Price x Investible weight factors

Issues such as declining revenues, strikes, rise in financing cost, narrowing profit margins, drop in sales etc., all count as non-systematic risks. These can easily be solved by making your portfolio diversified. By investing in a few different companies, you can spread out your risks. This is the crux of smart portfolio-building.

  • Sectoral bet

If you are bullish about the finance sector as a whole and not just the banking sector, you now have a benchmark that is better suited to your needs. You can now build ETFs, index funds as well as option trading strategies around a benchmark that is a better representation of the entire financial industry than Nifty Bank.
