Category : Investing Guides September 18, 20245 minutes read

What are Nifty and Sensex? While Nifty and Sensex are the two main indices representing the Indian stock market, they differ significantly in composition, methodology and impact. While Sensex tracks 30 large-cap stocks on the Bombay Stock Exchange (BSE), Nifty comprises 50 stocks listed on the National Stock Exchange (NSE). In this blog, we will understand the meaning of Nifty and Sensex, the importance of Sensex and Nifty in the stock market, the differences between them, and see how each index affects investment decisions and market sentiment. As an investor, it is important to understand the difference between Sensex and Nifty to make informed investment decisions.

Introduction

What are Nifty and Sensex? The Sensex, short for sensitive index, is a benchmark index that includes 30 major stocks listed on the Bombay Stock Exchange (BSE). It is an indicator of the performance of India’s leading blue-chip companies, reflecting market trends and investor sentiment. Meanwhile, the Nifty or National Stock Exchange Fifty is a comprehensive index that includes 50 stocks listed on the National Stock Exchange (NSE). It represents a broad spectrum of the Indian stock market and provides insights into various industries and sectors.

In this guide, we will explore the meaning of Sensex and Nifty, the fundamental differences between the Sensex and Nifty, and break down their compositions, methodologies, and their importance in the Indian financial market.

What is Sensex?

What is the Sensex? The Sensex is a benchmark index that tracks the performance of 30 large-cap stocks listed on the Bombay Stock Exchange. It provides insights into market trends and investor sentiment in the Indian stock market.

Now, how is Sensex calculated? It is not as simple as just adding up the stock prices. The Sensex is calculated using the free-float market capitalisation method. This means that it takes into account not just the total value of a company’s shares but specifically the portion that’s available for trading.

Each stock in the Sensex can be similar to a piece of a puzzle, with its size determined by its worth in the market. The Sensex is constantly being updated and adjusted to ensure it accurately reflects the ever-changing dynamics of the stock market.

So, when the Sensex hits new highs or lows, you need to understand that it’s not just a number but a reflection of the collective strength and resilience of India’s economy. When the Sensex is rising, investors and traders resort to buying stocks, which they see as a sign of positive market momentum. Conversely, if the Sensex declines, many investors may opt for a more cautious approach and stay away from major moves.

Now that we understand the meaning of Sensex, let’s understand how the 30 stocks in the Sensex are selected:

  1. Stock Exchange Listing: One of the key differences between Nifty and Sensex is the stock exchange listing. For Sensex, the chosen stocks must be listed on the Bombay Stock Exchange (BSE), ensuring they meet the regulatory standards of this major exchange.
  2. Market Capitalization: Preference is given to large-cap stocks with substantial market capitalization. These companies typically have a significant presence and influence within the market.
  3. Liquidity: Stocks included in the Sensex must demonstrate high liquidity, meaning there’s enough trading activity and demand for their shares in the market.
  4. Average Daily Turnover: The stocks selected should have a consistent and robust average daily turnover, indicating active trading and investor interest.
  5. Industry Representation: The Sensex aims for diversity by including stocks from a wide range of industries. This ensures that the index provides a balanced representation of various sectors of the economy.

Regular monitoring of Sensex trends is important for market participants as it provides valuable insights into overall market trends and sector-specific trends.
