Nifty vs Sensex: Major Differences You Didn’t Know

Sensex and Nifty are two popular indices that measure India's stock market performance. Both serve as the Indian equity market's primary barometer, though composition, calculation, and significance differ significantly. These differentiators are pertinent for every investor who wants to make informed decisions. 

What is Sensex?

Sensex, which stands for S&P BSE Sensex is the benchmark index for the Bombay Stock Exchange (BSE). The index consists of the 30 largest companies listed on BSE, selected based on market capitalization and liquidity and representation of key sectors in the Indian economy. Arching back to 1986, it can be said that Sensex is the most venerable and reliable of all in India, giving an overview of the performance of the Indian stock market.

What is Nifty?

Nifty, more formally Nifty 50, is the benchmark index of the National Stock Exchange (NSE). Nifty, on the other hand, has 50 companies from different sectors, thus giving it a wider representation of the Indian equity market as compared to Sensex. Launched in 1996, the Nifty 50 is administered by NSE Indices Limited and is widely used as a benchmark for equity mutual funds, derivatives trading, and investment strategies.

Sensex tends to be steadily quoted as a past benchmark and largely referred to by the media in its coverage.

Nifty, on the other hand, is mainly preferred among the traders, especially in derivative trading like Nifty futures and options.

7. Volatile & Stable

Since Nifty has more companies, it tends to be a little less volatile than Sensex, which is affected by the movement of individual stocks more significantly.

Understanding Market Volatility: India VIX: Meaning

An important variable that influences both Sensex and Nifty is market volatility. This is where India VIX comes into consideration.

What is India VIX?

India VIX, the Volatility Index, quantifies the expected volatility in the market in the next 30 days. Mostly termed as the 'fear index' as it used to move up during the times of uncertainty and generally rises with more expectations of fluctuations in the market as a result of lower value, whereas lower value suggests more stability in the market.

How India VIX Affects Nifty and Sensex?

When the India VIX goes up, investors expect volatility in the markets and tend to trade cautiously, indicating a possible downward movement in the market.

India VIX goes down; the market remains more stable and usually leads towards bullishness in Nifty and Sensex.

Traders and investors gauge the India VIX before undertaking any investments or trade decisions regarding their risk levels.

Which Index to Follow?

Both Nifty and Sensex are reliable indicators of the Indian stock market, but your decision needs to be made based on your investment approach.

The Nifty 50 can be more representative of the broader market because it has 50 stocks, which means it reduces the sectoral risks.

If you are looking for the historical track record, Sensex is an important tool for market movements and sentiments.
