Systematic Investment Plans (SIP) are driving a disconnect between where India’s mutual fund investors put their money and where returns are actually being generated, according to a new report.
Despite macroeconomic uncertainty, the Indian mutual fund industry held steady at Rs. 81.58 lakh crore in assets as of May 31, 2026. Equity funds saw their 63rd consecutive month of net positive inflow. However, the money is not going where the money is made. The report highlights a stark contradiction: some of the least-subscribed fund categories outperformed the most popular bets.
Micro-cap funds and small-cap funds delivered the highest returns in May, at around 5.7% and 3.4% respectively. In contrast, large-cap funds returned less than 1.5%, the weakest monthly performance among the major categories. Investors poured Rs. 8,565 crore into large-cap funds, nearly four times what small-cap funds received and more than double mid-caps.

This divergence shows a clear pattern of lower return, more flows. While the best performers were the smallest companies, the largest funds absorbed the bulk of retail savings. Flexi-cap funds, which delivered 2.1%, drew Rs. 5,350 crore, while Large and Mid-cap funds collected Rs. 2,617 crore at 1.9%.
The Math Doesn’t Favor the Investor
The unambiguous pattern of lower return, more flows is due to the growing trend of Systematic Investment Planning. Monthly standing instructions on large caps and flexi-cap index trackers mechanically route the bulk of retail savings toward the largest funds, regardless of monthly performance. The SIP calculation measures safer capitalisation to invest rather than chasing higher returns.
The SIP is a disciplined method of investing a fixed amount of money at regular intervals, such as monthly or weekly, into a mutual fund. Instead of a large, one-time lump sum, it allows investors to build wealth gradually with small contributions. In the micro-cap context, the SIP approach prioritizes capital preservation over chasing higher yields.

Investors are mechanically routing their savings toward the largest funds, even when those funds are underperforming smaller segments. This creates a scenario where the most popular funds often have the lowest returns, simply because they have the most money flowing into them.
Banking Sector Shows Similar Disconnect
The mismatch isn’t limited to small and large caps. The banking sector also shows a disconnect between targeted exposure and category breadth. BFSI funds led the race this month, returning 5.5% and attracting Rs. 1,013 crore. Within this sector, PSU Bank funds gained 6.9% and drew a net flow of Rs. 436 crore. Private Banks funds gained 6.5% and collected Rs. 329 crore together drawing Rs. 765 crore, while Broad basket Bank funds returned the same 6.5% as private banks but simultaneously saw Rs. 421 crore in redemption.
This trend suggests that many investors prioritize safety and liquidity over seeking the highest possible yield. The mechanical nature of regular contributions often overrides the opportunity to invest in higher-growth segments. Consequently, the market structure often rewards the passive flow of capital rather than the active selection of high-performing assets.
