India’s shift toward ETFs and index funds is real, but the attraction is cost and transparency—not certainty of return.
The scale of passive investing
AMFI’s May 2026 monthly note placed passive-fund assets at about ₹15.27 lakh crore, up from ₹15.19 lakh crore in April. The total includes multiple passive categories, and institutional allocations can make headline AUM look larger than retail adoption alone.
What an ETF provides
An ETF seeks to track an index before costs. It reduces manager-selection risk and usually charges less than active funds. It does not remove market risk, valuation risk or concentration risk. A Nifty 50 ETF can still be dominated by a small number of large companies and sectors.
Four checks before buying
Expense ratio is only the advertised cost. Tracking difference measures the realised performance gap. Bid–ask spread captures trading friction. Market liquidity and the creation-redemption process affect execution, particularly in sector, international and debt ETFs.
Index design is an active choice
Market-cap, equal-weight, factor and sector indices behave differently. Choosing the index is an allocation decision even when the product is labelled passive.
The bottom line: ETFs are efficient building blocks, not guaranteed-return products. Broad, liquid, low-cost funds may suit core exposure, while narrow thematic ETFs require the same valuation discipline as individual sectors.
