Betting on the House: Why Nifty Capital Market Funds Are Soaring

A Nifty capital market index fund is a “passive” mutual fund that tracks the Nifty Capital Markets Index. It may not select stocks based on research or prevailing market conditions. Instead, it only replicates the index. Consequently, the fund invests:

• In the same companies that are part of the index and

• In the same proportion as defined by the index methodology.

When the index is reviewed and its composition changes, the fund also adjusts its holdings to match those changes. This ensures the fund stays aligned with the benchmark it tracks.

One of the major potential advantages is a lower expense ratio compared to active equity funds. Since Nifty capital market index funds replicate the Nifty capital market, they do not require large research teams or frequent portfolio reshuffling. 

Due to this passive approach, the overall cost of managing the fund is generally lower than that of “actively managed” equity funds. This leads to lower expense ratios, which means a larger portion of the portfolio remains invested instead of being used towards fund management expenses.

Additionally, some more advantages you may realise are:

1. Participation in India’s Expanding “Investment Ecosystem”

India’s financial market awareness and participation have increased over the last few years. Studies show that, as of October 02, 2025, around 63% of Indian households (approximately 213 million) are now aware of at least one securities market product. Also, around 9.5%, or nearly 32.1 million households, actively participate in the markets.

Additionally, FY24–25 marked a breakout year for demat account growth in India. Reports show that around 4.1 crore new accounts were added, reflecting nearly 27% year-on-year growth. This pushed the total number of demat accounts to about 19.24 crore by March 2025, and further to over 20 crore by August 2025. (Source: Business Standard)

As these trends continue, businesses such as stock exchanges, brokerage firms, and AMCs may witness potential growth in:

•     Trading activity
•     Transaction volumes, and
•     Investment inflows.

A Nifty capital market fund may offer investors a potential opportunity to benefit from the long-term expansion of India’s financial sector.

2. Exposure Across Multiple Capital Market Businesses

Although a Nifty capital market fund is “sector-focused”, they do not invest only in one type of financial company. The fund tracks the Nifty capital markets index, which includes different types of businesses within the capital markets ecosystem. 

This creates exposure across:

•      Exchanges
•     Brokerage firms
•     AMCs
•     Depositories, and
•     Wealth management companies.

Note that the Nifty capital markets index funds follow a passive investment strategy. The fund manager does not actively select or remove stocks based on market views. Instead, the fund invests according to the prevailing composition of the Nifty capital markets index (as mentioned above).

Nifty capital markets funds carry “concentration risk” as they invest only in companies that are linked to India’s capital market system. This “narrow focus” gives exposure only to a specific part of the financial sector. 

As a result, index fund returns can be more volatile compared to diversified equity funds that invest across multiple sectors. Additionally, some more risks you must be aware of are:

1. Exposure to Investor Sentiment and Market Mood

As per the general market understanding, capital market companies depend heavily on market participation and trading activity. When equity markets rise and investor participation increases, the potential revenues of brokers, exchanges, and asset managers generally improve. 

However, during market downturns or long correction phases:

• Trading volumes decline and
• Investor sentiment weakens

This reduces income for these companies and can negatively influence their stock prices. In such situations, the Nifty capital markets index may decline, and since the fund tracks this index, the Net Asset Value (NAV) of the Nifty capital markets fund may also fall in line with the index movement.
 

2. Lack of Broad Market Diversification

Since the fund is focused only on capital market businesses, it does not benefit from diversification across different sectors such as:

• Healthcare
• Information Technology (IT), or 
• Consumer goods

As a result, if the financial services segment “underperforms”, the NAV of a Nifty capital markets fund can fall.

1. How is the portfolio of a Nifty capital market index fund constructed? 

The fund manager builds a portfolio that “mirrors” or replicates the Nifty Capital Market index. For example, as of May 29, 2026, the top three constituents by weightage in the index were:

• BSE Ltd.: 23.73%
• Multi Commodity Exchange of India Ltd.: 16.98%
• HDFC Asset Management Company Ltd.: 12.28%

Now, the Nifty capital market fund may also invest in these companies in similar proportions. Resultantly, a higher share of the fund’s total assets may be allocated to stocks with higher index weightage, while lower-weight stocks receive a smaller allocation.
 

2. Is the Nifty capital market index fund actively managed?

No, the Nifty capital market fund is an index mutual fund and is “passively” managed. There is no active stock picking or frequent trading based on market opinions. Portfolio changes may happen when the index rebalances.
 

3. How are the returns of the Nifty capital market index fund calculated?

The index fund returns depend directly on how the Nifty Capital Markets Index performs. 

• If the companies in the index gain value, the fund’s NAV (Net Asset Value) may also increase. 
• If the index falls, the fund’s NAV reflects that decline.

Note that the potential objective of a Nifty capital market fund is not to outperform the Nifty Capital Market index but to deliver returns that closely match its performance, after accounting for tracking errors.
