The Rise of a 'Set It and Forget It' Mindset
Passive investing has moved from a niche strategy to a mainstream movement in India. Assets in passive funds, which include index funds and Exchange Traded Funds (ETFs), have surged dramatically, with AUM growing nearly 18-fold in the seven years leading
up to 2025. Unlike active investing, where a fund manager tries to beat the market by picking winners, passive investing aims to simply mirror the performance of a market index, like the Nifty 50. This approach embraces a 'time in the market, not timing the market' philosophy. By buying and holding a fund that tracks the broader market, investors participate in overall economic growth without needing to constantly monitor individual stocks or react to short-term news cycles. This shift reflects a maturing investor base that is increasingly focused on disciplined, long-term wealth creation.
The Unbeatable Allure of Lower Costs
One of the most compelling reasons for the long-term commitment to index funds is their low cost. Actively managed funds employ teams of analysts and managers, which results in higher fees, known as expense ratios. These fees, which can seem small annually, have a massive corrosive effect on returns over time due to compounding. For instance, a Value Research analysis showed that over 15 years, a hypothetical ₹10 lakh investment in an active fund with a 1.5% fee would result in a corpus ₹8.6 lakh smaller than the same investment in an index fund with a 0.2% fee, based on cost alone. As investors become more aware of how fees impact their net returns, the mathematical advantage of low-cost index funds for long-term goals becomes undeniable.
Diversification on Autopilot
Index funds offer instant diversification, a core principle of sound investing. By purchasing a single unit of a Nifty 50 index fund, an investor gains exposure to the 50 largest companies on the exchange. This automatically spreads risk across various sectors and industries, reducing the impact that the poor performance of any single company can have on the overall portfolio. This built-in diversification provides a buffer against volatility and eliminates the complex and time-consuming task of building and maintaining a diversified portfolio of individual stocks. It’s a simple, effective way to avoid the pitfalls of concentrating all your capital in a few bets, making it an ideal strategy for investors who prefer a hands-off approach.
The Performance Paradox
For years, the primary appeal of active management was the promise of outperforming the market. However, data increasingly shows this is harder than it sounds, especially over the long term. Numerous studies have consistently shown that a majority of actively managed funds, particularly in the large-cap space, fail to beat their benchmark indices after fees are accounted for. According to the SPIVA India scorecard, 84.4% of Indian large-cap active funds underperformed their benchmark over the five years ending in 2025. While some active managers do outperform in the short-term or in less efficient market segments like small-caps, the consistency is lacking over longer 5- or 10-year periods. This performance data has led many investors to a logical conclusion: if you can’t consistently beat the market, the next best thing is to match it at the lowest possible cost.
A Foundational Shift in Investor Behaviour
Ultimately, the trend of holding index funds longer signals a behavioural shift. Investors are moving away from speculative, short-term trading and towards a more disciplined, goal-oriented approach. Data shows that the holding period for mutual fund assets is increasing, with the share of assets held for more than five years growing significantly. This indicates a greater understanding of the power of compounding and the importance of letting investments ride out market cycles. Rather than chasing hot tips or reacting emotionally to market volatility, investors are using index funds as the stable, long-term core of their portfolios, a strategy that aligns with achieving major financial goals like retirement. This patient approach is a hallmark of a maturing market, where long-term strategy is finally winning out over short-term speculation.
