How to Review an Existing Mutual Fund Portfolio
The short answer
Review a portfolio in a fixed order: list what you hold and which goal each holding is for, check whether your asset allocation has drifted from what you chose, look for overlap between schemes that hold the same securities, measure your own XIRR rather than reading fund factsheets, and check costs and exit terms. Compare each scheme against its own category and benchmark over the same period — a scheme whose whole category is out of favour is a different situation from one lagging its peers. Review at sensible intervals, not after every market move.
Most portfolios are not built; they accumulate. A fund bought after a good year, another added because a colleague mentioned it, an ELSS from a tax deadline, a SIP started and forgotten.
A review is how an accumulated collection becomes a portfolio again. Done in the right order, it takes an evening and answers more than a year of watching NAVs.
Step 1: Write down what you own and why
Start with a consolidated view of every folio across fund houses. A consolidated account statement from the RTAs, or the CAS you receive, gives you this in one place rather than by logging into several portals.
Next to each holding, write the goal it is for and roughly when that money is needed. Any holding you cannot assign a goal to is the first thing to examine — not necessarily to sell, but because a holding with no purpose cannot be evaluated against anything.
Step 2: Check allocation drift
Compare your current split between equity, debt and other assets against the allocation you intended. After a strong equity run, a portfolio set at 60% equity may now be at 75% — which means your risk rose without you deciding anything.
Drift is the most common finding in a first review, and the most consequential, because it changes the portfolio's risk rather than just its composition.
Step 3: Look for overlap, not fund count
Check whether your schemes actually hold different things. Several large-cap or flexi-cap funds typically share many of the same companies, so holding four of them may give you the diversification of roughly one, with four times the paperwork.
Overlap is not automatically a problem to fix by selling — exit loads and tax apply — but it tells you where new contributions should not go.
Step 4: Measure your own return, not the fund's
The return on a fund's factsheet assumes one investment held for the whole period. Your return depends on your dates and amounts, which is what XIRR measures.
Computing your own XIRR often reveals something a factsheet cannot: that the schemes performed reasonably while your own timing — adding after strong runs, pausing after falls — did most of the damage. That is a more actionable finding than any fund comparison.
Step 5: Judge performance against the right comparison
Compare a scheme with its own benchmark and its own category over the same period. A mid-cap fund down 12% in a year when mid-caps generally fell 15% did not underperform — its category was out of favour, which is a different fact with different implications.
Look across several distinct market periods rather than one. A single weak year is normal for a fund with a defined mandate; persistent lagging against its own peers over multiple periods is a stronger signal. Check also whether the scheme still does what it did when you bought it: a change of mandate, a significant shift in the portfolio's character, or a change in its riskometer are more substantive than a year of returns.
Step 6: Check the costs and the exit terms
Confirm the current expense ratio of each scheme and plan you actually hold — it changes over time, and the figure you checked when you invested may not be the one you are paying now.
Before acting on anything you find, check the exit load position and the tax consequence. A switch is a redemption, and a review that generates avoidable tax has cost you something real to fix something theoretical.
What a review is not
A review is not an instruction to trade. Most reviews should end with small adjustments, or with redirecting future contributions rather than selling anything.
Nor is it a monthly activity. Reviewing at sensible intervals — annually, or when your goals or circumstances genuinely change — gives you enough information to act on. Daily market movement does not.
Key takeaways
- Start with a consolidated view and assign every holding to a goal.
- Allocation drift is the most common and most consequential finding.
- Count what your schemes hold, not how many schemes you hold.
- Measure your own XIRR — a fund's published return is not your return.
- Compare each scheme with its own category and benchmark over the same period.
- Check exit load and tax before acting; redirecting new money often beats selling.
- Review at intervals, not after every market move.
