Today, let's embark on an exploration of the Nifty 50, one of the most significant stock market indices in India. The Nifty 50 represents the top 50 companies listed on the National Stock Exchange (NSE), showcasing a diverse range of sectors, including finance, technology, and consumer goods.
Unlocking Nifty's Core
The Nifty 50 index includes 50 companies, but it doesn’t treat each stock the same. Understanding how this index is weighted is important for making smart trading and investment choices.
What is Free-Float Market Capitalization?
• Market Capitalization generally refers to a company's total shares multiplied by their current market price.
• However, free-float market capitalisation specifically considers only the shares actively traded by the public. It excludes shares that are not regularly available for trading, such as:
- Promoter shares, which represent ownership by company founders or owners.
- Insider shares, which are owned by senior officers or directors; trading requires exchange notification.
- Shares held by government institutions, like LIC, and those in the President's name also hold significance.
- A higher proportion of free-float shares increases a company's weight in the Nifty 50 index.
