Why Sensex has 30 and Nifty has 50?
Is there any logic behind Sensex keeping only 30 stocks and Nifty 50 having 50 stocks in the index?

Sensex and Nifty are both benchmark indices of India. But they were designed by different exchanges with slightly different goals.
- Sensex was started in 1986 by BSE as India’s first equity index. At that time, the market was smaller and less liquid, so they picked 30 of the biggest, most actively traded companies to represent the market. A smaller number made it easier to calculate and maintain with the systems and data available then.
- Nifty 50 was launched later in 1996 by NSE. By then, Indian markets had grown, more sectors were listed, and technology had improved. NSE decided to cover more companies across more sectors, so they chose 50 stocks to get a broader picture of the economy while still keeping the index manageable.
So, there is no magical reason behind “30” and “50”. Both are just design choices. Sensex is narrower because it’s an older benchmark. Nifty 50 is broader as it came almost 10 years later than the Sensex.
