At its core, NSE serves as India’s largest digital marketplace for financial products. Just as Amazon connects buyers with sellers of products, NSE connects investors with companies through its advanced electronic trading platform to invest in NSE listed companies.

2. Clearing and Settlement

Think of NSE’s clearing function as a trusted middleman ensuring both buyers and sellers keep their promises. When you buy shares of a company:

Benchmark Index of the NSE

The NIFTY 50 is the benchmark index of the National Stock Exchange. Launched in 1996, the NIFTY 50 represents the top 50 companies listed on the exchange based on their market capitalisation and liquidity. Covering over 12 sectors of the economy, it serves as the barometer for the Indian stock market’s overall health and performance.

Features of NSE Index – NIFTY 50:

  • Free-Float Market Capitalisation: Only shares available for public trading are considered in the index calculation.
  • Performance Indicator: It captures approximately 54% of the NSE’s free float market capitalisation as of September 30, 2024.
  • Diversification: Companies across sectors like banking, IT, FMCG, and energy are included.

Apart from the NIFTY 50, other major indices on NSE include NIFTY 100, NIFTY Midcap 100, and NIFTY Bank, providing investors insights into specific segments of the market.

Major Indices Traded on NSE

Market indices tell us about the health of different parts of our economy. NSE’s indices help investors, from seasoned professionals to newcomers, understand how various sectors of the Indian economy are performing.

The NIFTY 50 is NSE’s most-watched index, working like a thermometer for India’s economic temperature. When you hear news anchors say “The market is up today,” they’re usually talking about the NIFTY 50. This index tracks India’s 50 largest companies, which together represent about 54% of the free float market capitalisation of the stocks listed on NSE as on September 30, 2024. Think of these companies as the Indian economy’s premier league – they include industry leaders from the technology, banking, energy, and consumer goods sectors.

For example, if the NIFTY 50 crossed 23,000 points in the near future, these top 50 companies would collectively grow stronger, often reflecting increased profits, better economic conditions, or positive investor sentiment. This matters because when these companies do well, they generally create more jobs, pay more taxes, and contribute more to India’s growth.

The NIFTY Bank index tells an equally important story. Banks are like the blood vessels of our economy – they help money flow where it’s needed. This index tracks 12 of India’s largest banks, both government-owned and private. When these banks show strong performance, it usually means businesses are growing (taking loans) and people are prospering (saving money).
