Many investors are questioning their Systematic Investment Plans (SIPs) due to recent muted equity market returns. However, historical data suggests that periods of low initial returns have often paved the way for stronger long-term growth. Rather than stopping, understanding the benefit of accumulating units during market dips is key, alongside a regular review of fund performance.
Indian equity investors, particularly those using Systematic Investment Plans (SIPs), have encountered a period of muted returns as the Nifty 50 Total Returns Index has faced stagnation in recent months. When SIP returns stay in the single digits over several years, it is natural for investors to question whether the strategy remains effective. However, a long-term look at market cycles suggests that such periods of underperformance are not always a signal to pause.
Historical Context of SIP Cycles
A study conducted by WhiteOak Capital Mutual Fund, analyzing data for the BSE Sensex TRI from August 1996 through June 2026, provides a counter-intuitive insight. The research found that periods where the first five years of SIP returns were 8% or lower actually yielded higher long-term results. On average, these periods were followed by 10-year SIP returns of 18.3%. In contrast, periods that began with stronger initial five-year returns (above 8%) delivered an average 10-year return of 14.7%.
This phenomenon is rooted in the concept of rupee-cost averaging. When equity markets remain flat or decline, the fixed monthly investment amount purchases a larger number of mutual fund units. These accumulated units are then well-positioned to benefit when the market eventually enters a recovery phase. By maintaining the SIP during low-return periods, investors are essentially lowering their average purchase cost, which can amplify gains once market sentiment turns positive.
When to Review Instead of Staying
While historical data suggests that sticking to an SIP during market downturns can be beneficial, this does not mean investors should hold on blindly regardless of the fund's quality. It is essential to distinguish between a temporary market cycle and a fund that is structurally underperforming. Investors should periodically review their portfolio to ensure that the specific mutual fund has not consistently lagged behind its benchmark or peer group over a meaningful timeframe.
Furthermore, individual financial circumstances change. A review is necessary if the original investment goal, time horizon, or risk tolerance has shifted. If the fund manager has changed significantly or the investment strategy no longer aligns with the investor's objectives, adjusting the portfolio may be appropriate regardless of short-term market returns.
Tax Considerations
Before making any decision to redeem or halt investments, investors should also consider the tax implications. For equity-oriented mutual funds, short-term capital gains (on units held for less than 12 months) are taxed at 20%. Long-term capital gains on units held for more than 12 months are subject to a tax of 12.5% on gains exceeding Rs 1.25 lakh in a financial year. Factoring in these tax costs is a standard part of evaluating whether changing an investment strategy is financially logical. The most effective approach often involves balancing long-term patience with regular, objective assessments of fund performance and personal financial needs.
