What is a Index Funds Fund?

High Volatility

Index Funds are passively managed mutual funds that aim to replicate the performance of a specific market index — such as the Nifty 50 or Sensex — by generally holding the index's constituent stocks in similar weights, subject to tracking error. Unlike actively managed funds, there's no fund manager trying to pick winning stocks or time the market, which typically results in a much lower expense ratio and returns that closely track (rather than try to beat) the index, minus a small tracking error.

Key Terms

Tracking Error

The difference between an index fund's returns and the actual index it tracks, caused by expense ratio, cash holdings, and rebalancing lag — lower tracking error means the fund more closely mirrors the index.

Expense Ratio

The annual fee (as a % of assets) an AMC charges to manage the fund — Index Funds typically have the lowest expense ratios among equity mutual funds since there's no active research/stock-picking cost.

Frequently Asked Questions

Which Sensex index funds have the lowest tracking error right now?

+
As of 15 October 2026, the Sensex index funds with the lowest tracking error are Nippon India Index Fund - BSE Sensex Plan (0.03%), ICICI Prudential BSE Sensex Index Fund (0.03%) and UTI BSE Sensex Index Fund (0.03%). Funds tracking the same index should return almost the same, so the one that follows the index most closely ranks first. Past performance is not indicative of future results.

How are Index Funds ranked on FundSageAI?

+
Funds tracking the same index should deliver nearly identical returns, so FundSageAI groups Index Funds by the index they track (Nifty 50, Sensex, Nifty Next 50, Midcap 150, Smallcap 250, Nifty Bank) and ranks each group by tracking error — how closely the fund follows its index, lower is better. Expense ratio is shown alongside, since it is the other cost of owning an index fund. Direct-Growth plans only.

Are Index Funds better than actively managed funds?

+
It depends on the category and time period. In large cap equity, many actively managed funds have struggled to consistently beat their benchmark index after fees, making Index Funds a popular low-cost alternative. In less-researched segments like small cap, skilled active managers have more often demonstrated an ability to add value — though this varies by fund and period.

What is the expense ratio of a typical Index Fund?

+
Direct Plan Index Funds in India typically charge expense ratios between 0.1% and 0.3% per year, significantly lower than actively managed equity funds (often 0.5%-1.5% for Direct Plans), since there's no active stock-picking research cost.

Which index do most Index Funds in India track?

+
The Nifty 50 and Sensex (BSE 30) are the most commonly tracked indices, representing India's largest companies. Some Index Funds also track the Nifty Next 50, Nifty 500, or specific sector indices.

How often is this ranking updated?
