How Do They Select Stocks For NIFTY 50

NIFTY 50 follows the trends and patterns of blue-chip companies, i.e. the most liquid and largest Indian securities.

There is also an eligibility criterion to first be considered a potential player.

  • The company must be based in India and listed on the National Stock Exchange (NSE).
  • The stock should be highly liquid, measured through its average impact cost — the cost of executing trades relative to its index weight and market capitalization. For eligibility, this impact cost must stay at or below 0.50% for six months, with at least 90% of trades evaluated on a ₹10 crore portfolio.
  • The company must have been traded on every single trading day over the past six months.
  • The stock’s average free-float market capitalization should be at least 1.5 times that of the smallest company currently included in the index.
  • Companies that issue Differential Voting Rights (DVR) shares can also be included in the index.
The Index is reconstituted every six months to make sure that the index’s performance is judging the whole market carefully. Also NIFTY 50 is calculated based on free-float market cap.

How is NIFTY for Share Market Calculated?

NIFTY 50 is calculated using the Free-Float Market Capitalization Weighted Method — meaning the index value is based on the total market value of India’s top 50 companies that are available for public trading.

NIFTY Index Value = (Current Free-Float Market Cap of 50 Companies / Base Market Cap) × 1000

  • Base Year: 1995
  • Base Value: 1000
  • Base Market Cap: Market cap of NIFTY companies in 1995 (adjusted)

Suppose the total free-float market cap of all 50 companies today = ₹120 lakh crore

Base Market Cap (adjusted from 1995) = ₹12,000 crore
NIFTY = (120,00,000 crore / 12,000 crore) × 1000 = 10,000

So NIFTY would trade around 10,000.

History Of NIFTY 50

  • 1995–1999: Birth of NIFTY 50

NIFTY 50 was launched in 1996 with 1995 as its base year (base value 1000). It became India’s first modern, automated, free-float market-cap index, representing the country’s top companies and quickly emerging as a standard benchmark for investors.

  • 2000–2003: Dot-Com Boom & Crash

The early 2000s saw tech stocks soar, making IT companies dominant in the index. But when the dot-com bubble burst, NIFTY fell sharply, testing market resilience and reshaping sector weights within the index.

  • 2004–2008: Growth & Market Reforms
India experienced a strong economic expansion, and NIFTY benefited from rising corporate profits and new sectors. NSE also introduced index derivatives like NIFTY Futures & Options, which became some of the world’s most traded contracts.
 
  • 2008–2010: Global Financial Crisis & Recovery
NIFTY dropped over 50% during the 2008 financial crisis, but the recovery was swift as global liquidity improved. By 2010, the index returned to new highs, reflecting India’s growth momentum.
 
  • 2014–2019: Long Bull Run
A stable economic environment and rising foreign investment pushed NIFTY to major milestones, including crossing 7,000 in 2014 and 10,000 in 2017. Financials, IT, FMCG, and autos became the dominant sectors.
 
  • 2020–2021: COVID Crash & Fastest Recovery
NIFTY fell nearly 40% during the pandemic shock in March 2020 but recorded one of its fastest recoveries. Within months, it hit fresh all-time highs, driven by liquidity, tech adoption, and strong corporate earnings.
 
  • 2022–Present: India’s Market Surge
India became one of the world’s top stock markets by market cap. NIFTY saw major structural shifts as companies in banking, technology, energy, and conglomerates like Reliance and Adani gained influence. The index continues to reflect India’s rapid economic transformation.
