Overview on Nifty 500 Index
The Nifty 500 is a broad market index that represents the performance of the top 500 listed companies in India, selected based on full market capitalisation and liquidity. It covers large cap, mid cap, and small cap stocks, accounting for a significant portion of the Indian equity market. Because of its wide coverage, the Nifty 500 is often used as a benchmark to track overall market trends and the performance of diversified equity portfolios
What is the Nifty 500 Index?
The Nifty 500 index includes companies across all major market capitalisation segments, making it a broad representation of the Indian equity market. It comprises large cap, mid cap, and small cap companies, each contributing differently to the overall index composition.
Large cap companies
Large cap companies account for the largest portion of the Nifty 500 index. These businesses generally have an established market presence and relatively stable operations. They account for approximately 70.8%* of the total index weight, which influences the overall movement of the index. As per regulatory guidelines, large cap stocks are those ranked 1 to 100 on recognised exchanges.
Mid cap companies
Mid cap companies constitute around 18.6%* of the index. These firms are typically in an expansion phase and may offer higher long-term growth potential compared to large caps, along with relatively higher volatility. As per regulatory guidelines, mid cap stocks are those ranked 101 to 250 on recognised exchanges.
Small cap companies
Small cap companies contribute roughly 10.4%* to the index. These companies may experience higher volatility and carry higher risk. Their limited weight within the index helps moderate their overall impact on index-level fluctuations. As per regulatory guidelines, small stocks are those ranked 251 and beyond on recognised exchanges.
By including companies across market capitalisation segments, the Nifty 500 reflects broader market trends and provides a comprehensive view of the Indian equity market.

Why choose the Nifty 500 Index?

How is the Nifty 500 calculated?
The Nifty 500 index is calculated using the free-float market capitalisation method. This approach considers only those shares that are available for public trading. Shares held by promoters, the government, strategic investors, trusts, or other locked-in holdings are excluded.
To calculate the index value, the combined free-float market capitalisation of all 500 constituent companies is computed and compared with the market capitalisation during the base period.
The calculation follows a simple formula:
Index value = (Current market capitalisation / Base market capitalisation) x 1,000
The base date for the Nifty 500 index is January 1, 1995, with a base value of 1,000. Company weights are determined by their respective free-float market capitalisation, which means larger companies have a greater influence on index movements.
Benefits of the Nifty 500
- Wide market coverage
The Nifty 500 covers more than 90% of India’s listed equity market capitalisation. It includes companies from a wide range of sectors, which may help reduce company-specific and sector-specific concentration risk.
- Exposure across market caps
The index includes large cap, mid cap, and small cap companies. Large caps contribute relatively lower volatility, while mid and small caps add exposure to potential long-term growth over time. Overall, the index reflects a diversified equity exposure.
- Balanced profile
Compared to indices focused solely on mid cap or small cap stocks, the Nifty 500 may show lower volatility. However, since the index has more than 65% exposure to equities, it should be considered high risk and subject to market fluctuations.
- Suitability for long-term horizons
Due to its diversified structure, the Nifty 500 may be suitable for investors looking for potential wealth creation over the long term, provided they have a high risk appetite and the ability to remain invested through market cycles.
How to invest in the Nifty 500?
It is not possible to invest directly in a market index such as the Nifty 500. An index primarily serves as a benchmark to measure market performance and compare portfolio outcomes.
Investors seeking exposure to the Nifty 500 may consider passive investment products designed to track the index. These include index mutual funds and ETFs that aim to mirror the index composition and performance.
Another approach involves constructing a portfolio that closely resembles the index by holding constituent stocks in similar proportions. However, this requires careful execution, regular rebalancing, and ongoing monitoring.
A third way to get indirect exposure to some of the index’s constituents is through actively managed funds that are benchmarked against this index. Such funds seek to potentially outperform the index over the long term.
