# Lumpsum edges STP in medium term, gap narrows over time 2026-08-21T02:36:25+00:00 | Business & Economy | Indian Opinion Desk Corroboration: 1 independent outlet A 25-year analysis of Nifty 50 Total Return Index data by FundsIndia shows that investing a large corpus as a lump sum delivers a modest return advantage over a six-month systematic transfer plan (STP) in the medium term. Over a one-year holding period, the average annualised return from lump sum was 16%, three percentage points higher than the 13% from STP. The gap narrowed to one percentage point over three, five and seven years. Over longer holding periods of 10, 15 and 20 years, the average annualised returns from both approaches converged at 14-15%. The data indicates that the method of deploying a large corpus matters more for shorter and medium-term investments, while the difference becomes negligible for long-term investors. The analysis covers data from 2000 to 2025 and accounts for different market cycles. ## Indian Opinion Analysis The key insight for Indian investors is that the timing of market entry has a meaningful impact on medium-term returns, but this effect largely disappears beyond 10 years. This reinforces the principle that long-term equity investing rewards patience regardless of the deployment method. For those with a lump sum who fear near-term volatility, an STP can reduce anxiety without materially hurting long-term outcomes. The study uses the Nifty 50 TRI, which includes dividends, making it a more accurate return measure than the price index. Investors with a horizon under five years should consider their risk tolerance before deciding on a deployment strategy. ## Coverage - livemint.com Presents data-driven comparison without advocating for either approach, citing FundsIndia research.
