Recent analysis of investors who began mutual fund investments during the September 2024 market peak reveals starkly different outcomes based on investment approach. According to the latest reports, lump sum investors who deployed ₹2 lakh at market peak faced significantly deeper losses compared to SIP investors. The comparison used a monthly SIP of ₹10,000 versus a lump sum investment of ₹2 lakh made at the same time. This analysis comes as the Sensex has declined nearly 9.4% so far in 2026 and remains over 4% lower compared to the previous year, highlighting the importance of timing and investment methodology in volatile market conditions.
The core principle behind SIP investing is rupee cost averaging, where investors systematically invest a fixed amount regardless of market conditions. As reported by the source, this approach allows the same investment to purchase more units when markets fall and fewer units when markets rise. An example provided shows ₹5,000 invested monthly at different NAV levels: ₹100 (50 units), ₹50 (100 units), and ₹75 (66.7 units). Despite price fluctuations, the average cost per unit remains lower than investing the full amount at market peaks, making SIPs popular among long-term retail investors seeking discipline without constant market prediction.
Large-cap mutual funds delivered relatively stable performance but returns remained modest for most SIP investors. Among the better-performing schemes, the Bank of India Large Cap Fund generated nearly 4.4% XIRR through SIP investments, with a total investment of ₹2 lakh growing to around ₹2.07 lakh. A few other schemes, including Taurus Large Cap Fund and Quant Large Cap Fund, delivered marginal gains in the 1-2% range. However, several large-cap funds barely managed to avoid losses, while others delivered negative returns despite continuous monthly investing. The Nifty 50 TRI return was reported near minus 2%, reflecting the difficult market environment, with some investors suffering losses between 4 and 5.5% in certain schemes.
Mid-cap mutual funds painted a much stronger picture for SIP investors, with ICICI Prudential Midcap Fund generating nearly 17% XIRR for SIP investors. A ₹2 lakh investment through monthly contributions reportedly grew to more than ₹2.27 lakh. Other schemes such as HSBC Midcap Fund also delivered returns exceeding 14%. Several mid-cap funds generated returns in the 8-9% range, outperforming the Nifty Midcap 150 TRI benchmark, which delivered around 7.1% returns. However, the category also showed wide performance gaps between funds, with some schemes generating only around 1% returns while others delivered losses close to 9%.
Small-cap mutual funds demonstrated the highest risk-reward potential, with Union Small Cap Fund emerging among the stronger performers with approximately 13.4% XIRR through SIP investing. Several other funds delivered returns in the 9-10% range, significantly outperforming the Nifty Smallcap 250 TRI benchmark, which delivered roughly 3% returns during the same period. However, the risk factor remained equally high, with some small-cap schemes posting losses approaching 9.5% despite regular SIP investments. The risk associated with lump sum investing became most visible in small-cap funds, where even the best-performing lump sum investment reportedly generated returns of only around 2%. Most other schemes either stayed flat or slipped into negative territory, with investor losses touching nearly 13% in several cases.
