can be powerful wealth-creation tools, but a “buy and forget” approach may not always be the best strategy. Periodic portfolio reviews help investors ensure their investments remain aligned with their financial goals, risk appetite, and asset allocation targets. Experts explains how often should investors review their mutual fund portfolio, when rebalncing is required and what mistakes investors should avoid.
How often should investors review their mutual fund portfolio?
Reviewing a mutual fund portfolio should be a disciplined exercise, explains explains Arijit Sen, SEBI Registered Investment Adviser, Co-Founder, Merry Mind.
- I recommend a light tactical check at periodical interval to monitor allocation drift, concentration
- and any manager or mandate alerts, and a deeper strategic review at least once a year.
“Regular checks help you spot allocation slippage — for example, when equity exposure has grown far beyond your target because of a market rally — while the annual review is the time to reassess whether each fund still serves the original goal, whether the expense ratio and tracking error remain competitive, and whether the manager’s tenure and process are intact,” he pointed out.
What are the key indicators that suggest a portfolio needs rebalancing?
Rebalancing should be triggered by measurable deviations rather than gut feeling.
Practical triggers include:
- allocation drift of more than five to ten percentage points from your target,
- a single sector or stock representing an outsized share of your equity exposure,
- a sustained change in a fund’s volatility or beta that pushes the portfolio outside your risk tolerance.
“Rebalancing is not about timing the market; it is about restoring the portfolio to the risk profile and asset mix that match your objectives.”
Also, where possible, rebalance using new contributions and systematic investments to minimise transaction costs and tax impact.
What are the biggest mistakes investors make while reviewing mutual funds?
Investors commonly make avoidable mistakes when reviewing funds.
For example:
- chasing last year’s top performers,
- reacting emotionally to short‑term drawdowns,
- ignoring the tax and exit‑load consequences of switching,
- and failing to check for mandate drift or manager changes are frequent errors.
“Another common mistake is focusing solely on absolute returns without considering risk, costs and the fund’s role in the portfolio; this undermines compounding and increases churn,” the expert concludes.
Rather than chasing short-term performance, investors should adopt a disciplined review process focused on long-term goals, asset allocation and risk management. Regular monitoring, timely rebalancing and avoiding emotional decisions can help preserve portfolio health
