All Indices

Stock market indices are considered benchmarks that represent the performance of a specified group of equities or stocks. These stocks are carefully selected based on criteria such as market capitalization, investment strategy, industry, or sector. Investors rely on market indices to understand the market movements and analyze the performance of their investments. Each index highlights a particular market segment - for example, Nifty Bank represents bank sector stocks.

Globally and in India, major market indices are used as a barometer, signalling market trends, investor sentiment, and economic health.

Stock market indices are often calculated using particular mathematical methods. These approaches are designed to reflect how all the stocks in an index perform accurately. Some commonly used methods are outlined below:

• Price-Weighted Method

  :

  In this approach, stocks with high stock prices have a greater impact on the index performance. So, companies relatively small in size but with high share prices can significantly impact the performance of the index.

  The influence of each stock in the index solely depends on its price, not on its overall size. A known example of this method is the Dow Jones Industrial Average and Nikkei 225.

• Market Capitalization-Weighted Method

  :

  In this approach, companies with larger market capitalization exert more influence on the index. Here, the size of the company matters more, meaning larger companies impact index movements rather than the smaller ones. This widely-adopted calculation approach helps to reflect the true economic significance of each company present in the index.

  Earlier, Nifty and Sensex were popularly calculated using this method.

• Equal-Weighted Method

  :

  As the name suggests, this approach helps to analyze indices in which companies contribute equally, regardless of their share price or size. Smaller companies receive comparatively higher importance than market-cap weighted indices. These companies may provide greater growth potential, but could also lead to higher volatility.

• Free-Float Market Capitalization in India

  :

  The free-float market capitalization approach is widely adopted by major Indian market indices. Here, the stocks included in the index are based on the weights of each security depending on the free float market cap. Equities available for public sharing, excluding promoter holders and government-owned shares, are considered in this method.

  To ensure consistency over time, index calculations are also adjusted for different corporate actions such as stock splits, bonus issues, and dividends. Popular Indian indices like Sensex, Nifty, and SX40 are based on the free-float market cap method.

You'll find various types of market indices, each serving a different purpose. Let's take a look at some of the index categories:

1. Market Capitalization-Based Indices: This category includes indices such as large-cap, mid-cap, and small-cap. Such indices are created based on the size of the companies. Monitoring market-cap-based indices helps investors analyze how companies of different sizes are performing in the market. A few examples include indices like NIFTY 100 and NIFTY Smallcap 250.
2. Broad Market Indices: Indices present in this category reflect the performance of the overall stock market or a large portion of it. They represent equities of companies across sectors and market capitalization. For example, NIFTY 50 and SENSEX. These indices provide a general overview of market trends and investment performance.
3. Sectoral Indices: This category of indices tracks the performance of different industries in the market, such as IT, banking, energy, pharmaceuticals, etc. Investors analyze these indices to understand and get insights into how a particular sector is performing in the market.

   You can find indices such as NIFTY Bank and NIFTY IT in this category.

4. Thematic Indices: Indices under this category represent companies based on specific themes or ideas, such as infrastructure, manufacturing, ESG, etc. These indices are different from sectoral as they are created based on relevance to the chosen theme rather than sector. You may find equities from various sectors, but they are analyzed based on a common investment idea.

   Examples can include NIFTY 100 ESG or NIFTY India Internet Index.

5. Global Market Indices: International markets and economies are tracked under global indices. Investors use these indices to track global market trends and compare how the domestic market is performing with other countries. Indices like the MSCI World Index or the NASDAQ Composite come under this category.
6. Fixed Income Indices: Fixed income indices track the performance of debt instruments like government securities, corporate bonds, treasury bills, and money-market instruments. They are widely used as benchmarks for debt mutual funds and conservative investment strategies.

   Common examples include NIFTY G-Sec Index, NIFTY Corporate Bond Index, and BSE Gilt Index.

7. Hybrid Indices: Hybrid indices combine multiple asset classes, typically equity and debt, into a single index. These indices aim to reflect balanced or asset-allocation-based investment strategies. These indices are a useful tool for fund managers to evaluate their hybrid fund or consider the same as an underlying benchmark.

   Some popular examples of hybrid indices include the NIFTY Equity Debt Index and Balanced Advantage-style indices.

8. Strategy Indices: Strategy indices are designed using specific investment strategies or factors such as value, quality, low volatility, momentum, or equal weighting. These indices follow predefined rules rather than traditional market-cap weighting.

   NIFTY Low Volatility 50, NIFTY Alpha 50, NIFTY Value 20, and NIFTY Equal Weight Index are common examples of strategy indices.

Indian market indices are used to measure the overall performance of the Indian stock market. NSE (National Stock Exchange) and BSE (Bombay Stock Exchange) primarily manage these indices. They represent different market segments, from large-cap stocks to sector-specific companies.

Indian stock market indices are essential tools for individuals looking to invest in the Indian stock market, as they help track performance, analyze investments, and monitor market trends.

Both global and Indian market indices help to track market performance; however, they follow different structures and scopes. Let's understand the difference between them:

Let's take a look at some of the major market indices in India:

• SENSEX

  : This index includes equities of 30 large-cap companies listed on the BSE.

• NIFTY 50

  : This index includes equities of the 50 top companies listed on NSE.

• NIFTY IT

  : This index includes equities of companies providing information-technology services.

• NIFTY Bank

  : This index includes equities of banks.

• NIFTY Midcap 100

  : This index includes mid-sized companies.

These represent the core of all indices in the Indian stock market, followed by investors.

Investors use indices to gauge overall market performance and investor sentiment accurately. It helps them:

• Assess the market direction, whether it is trending upward, downward, or moving sideways.
• Compare their portfolio against other major indices and analyze the performance of their investments.
• Understand economic trends, identify sector strengths, allocate assets effectively, and diversify to reduce risks.

In index trading, you buy and sell instruments that track an index rather than individual stocks. This can be done through:

• Index Future & Options
• Index Mutual Funds
• Exchange-traded Funds

Index trading provides exposure to a broader market segment efficiently.
