According to DSP Mutual Fund's September 2026 Netra report, missing just 10 best trading days out of 11,025 sessions over 47 years reduced wealth multiplication from 607x to 213.5x - a 65% reduction in terminal wealth. The analysis, covering trading days from May 2, 1979 to August 31, 2026, reveals that compounding turns what appears as a small 2.5 percentage points annual underperformance into a massive gap in final corpus. As the report notes, the range is enormous: 213x if the 10 best days are missed versus 1,733x if the 10 worst days are avoided - an 8.1x difference in terminal wealth created by just 20 exceptional trading sessions. The best and worst days are often clustered around periods of extreme volatility, when jittery investors typically head for exits.
According to Mint reports, investors often describe themselves as long-term investors but struggle to maintain this commitment during market volatility. Rhishabh Garg, CEO of FundsIndia.com, explains that investors typically use 'long term' to describe return expectations rather than fixed investment horizons. The clearest signs of performance chasing include changing investments based on trailing one- to three-year returns rather than original investment plans, and recent underperformance becoming the primary reason for fund switches. Investors should monitor how frequently they check portfolios and whether their mood aligns closely with latest quarterly returns.
As reported by The Economic Times, frequent trading can quietly eat into returns through multiple small charges that add up significantly. Varun Saboo, Head – Equities at Anand Rathi Share and Stock Brokers, explains that for long-term investors doing SIPs or occasional lump-sum investments, UPI charges are a rounding error against multi-year compounding. However, these costs matter far more for high-frequency traders, small-ticket transactions, and thin-margin intermediaries where costs compound per transaction. The cumulative impact of Securities Transaction Tax (STT), transaction charges, GST on brokerage, stamp duty, and UPI-related charges can create a real drag on returns, particularly for active traders.
According to the Mint report, Garg recommends making important investment decisions in advance when markets are not under immediate pressure. The 7-5-3-1 framework for SIP investors includes a minimum seven-year commitment horizon, diversifying equity allocation across five distinct investment styles, increasing SIP amounts by at least 10% annually, and recognizing three emotional phases: disappointment, irritation, and eventually panic. A predefined rebalancing rule can help investors rebalance when equity allocation moves around five percentage points away from intended allocation. As per Business Standard, successful long-term investors focus on quality businesses with strong earnings, capable management and sustainable growth prospects rather than chasing multibagger stories.
As highlighted by The Economic Times, portfolio resilience now means surviving regime uncertainty - not knowing if the next macro shock is a hike, currency shock, or trade-tariff shock. It requires liquidity buffers to avoid forced selling, genuine diversification across uncorrelated return drivers, and position-sizing discipline over prediction. Saboo emphasizes that selectivity over wholesale de-risking is the better approach for most investors, with better results from tilting toward quality and reasonable valuations rather than blanket exits based on valuation alone. According to Business Standard, successful long-term investors avoid selling simply because markets have turned volatile or because a stock has delivered short-term gains, focusing instead on fundamentals and their original investment thesis.
