Tighter scheme categorisation, disclosure of risk and expense details, nomination requirements and stress testing for small-cap funds all change what you can see and compare. Here is what matters for your portfolio.
Mutual fund regulation rarely makes for exciting reading, which is unfortunate, because SEBI's rule changes over recent years have quietly done more for ordinary investors than most product launches. The direction has been consistent: make schemes comparable, make costs visible, make risk measurable and make it harder to be misled.
Here is what has changed, why it exists, and what you should actually check in your own portfolio.
Scheme categorisation: why every fund house has similar funds
Before categorisation rules, a fund house could run a dozen equity schemes with overlapping mandates and confusing names, making genuine comparison almost impossible. SEBI's categorisation framework fixed this by defining a limited set of categories with specific rules, and permitting generally one scheme per category per fund house.
| Category | Defining rule |
|---|---|
| Large cap | Predominantly invested in the largest listed companies by market capitalisation |
| Mid cap | Predominantly invested in companies ranked below the large-cap band |
| Small cap | Predominantly invested in companies below the mid-cap band |
| Large and mid cap | Substantial minimum allocation to each of the two bands |
| Flexi cap | Predominantly equity with freedom to allocate across market capitalisations |
| Multi cap | Minimum allocations required across large, mid and small caps |
| ELSS | Equity-linked savings scheme with a statutory lock-in |
The practical benefit: a large-cap fund from one house is genuinely comparable to a large-cap fund from another, because both must follow the same allocation rule. Before this, the same label could mean very different portfolios.
The practical limitation: categorisation constrains the label, not the quality. Two funds in the same category can still perform very differently based on stock selection and expenses.
The riskometer, and what it does and does not tell you
Every scheme must display a riskometer with a risk level from low to very high, calculated from the actual portfolio rather than assigned by the fund house. It is updated monthly and disclosed.
What it is good for: catching drift. If a fund you bought as moderate risk is now showing very high, its portfolio has changed and you should look at why.
What it is not good for: comparing two funds in the same category, since they will usually show the same level. It is a category-level signal, not a fund-selection tool.
Cost disclosure and why the expense ratio deserves your attention
The total expense ratio is deducted from the fund's assets daily. You never see it as a line item, which is precisely why it gets ignored.
The difference compounds brutally. On a Rs 10,000 monthly SIP over 20 years at an assumed 12 percent gross return, a 0.5 percent expense ratio versus a 2 percent expense ratio produces a difference in final corpus running into many lakhs. Nothing about the fund's strategy changes; the cost simply eats a growing share of the compounding.
Two actions follow:
- Check whether you hold regular or direct plans. Direct plans have lower expense ratios because they exclude distributor commission. If you research your own funds, you are paying for advice you are not receiving.
- Compare the expense ratio within the category before selecting. In index funds particularly, where the portfolio is defined by the index, cost is close to the only differentiator that matters.
You can model the effect of different cost assumptions in the SIP calculator by comparing outcomes at different net return rates.
Stress testing for mid and small cap funds
SEBI required fund houses to publish stress test results for mid-cap and small-cap schemes, disclosing how many days it would take to liquidate a specified portion of the portfolio under stressed conditions.
The reason is liquidity, not performance. Small-cap stocks can become very difficult to sell quickly during a sharp decline. If a large number of investors redeem simultaneously, a fund may be forced to sell its most liquid holdings first, leaving remaining investors with a less liquid portfolio.
What to do with the disclosure: treat a long liquidation estimate as a reason to size your small-cap allocation conservatively and to hold it with a genuinely long horizon, not as a reason to panic. Small-cap funds are the wrong place for money you might need in three years, and the stress tests quantify why.
Nomination requirements
SEBI has tightened requirements around nomination for mutual fund folios and demat accounts, requiring investors either to register a nominee or to formally opt out.
This sounds administrative and is genuinely important. Without a nominee, transmission of holdings after death becomes a slow, document-heavy process for the family at the worst possible time. With a valid nomination, it is comparatively straightforward.
Check every folio you hold. Many investors registered a nominee once, years ago, and have since married, had children or lost the person named. Also note that a nominee is a trustee for the legal heirs rather than automatically the final owner, so nomination is not a substitute for a will.
Other changes worth knowing
Faster redemption and settlement timelines mean money reaches your account sooner after redemption, which improves the practical liquidity of debt and liquid funds used for short-term needs.
Standardised performance disclosure requires funds to show returns against a defined benchmark and in a prescribed format, reducing the scope for selective presentation of favourable periods.
Scheme-level disclosure of portfolio holdings at defined intervals lets you actually see what you own, including overlap between funds you hold. Portfolio overlap is one of the most common hidden problems in retail portfolios: four different equity funds can hold substantially the same top ten stocks.
Rules around unclaimed amounts and inactive folios have been tightened, with clearer processes for claiming money from folios that have gone dormant.
A portfolio review checklist
- Count your funds. More than five or six equity schemes almost always means duplication rather than diversification.
- Check for overlap. Compare the top ten holdings of your equity funds. Heavy overlap means you are paying multiple expense ratios for one portfolio.
- Confirm direct versus regular. Switching to direct plans is straightforward, though check the tax and exit load implications before switching.
- Verify nominations on every folio. Update anything stale.
- Compare each fund's expense ratio against the category average.
- Check the riskometer against what you thought you bought.
- Size small-cap exposure honestly against your actual time horizon.
- Consolidate rather than accumulate. New schemes launch constantly; almost none of them solve a problem your portfolio actually has.
What regulation cannot do
SEBI can make schemes comparable, costs visible and risks disclosed. It cannot stop investors from buying whatever performed best last year, holding fifteen overlapping funds, or redeeming in a panic during a drawdown.
The disclosures only help if you read them. The single highest-return activity available to most mutual fund investors is an hour spent reviewing what they already own.
What the disclosures cannot protect you from
The most expensive mistakes in retail mutual fund investing are behavioural, and no circular addresses them.
Chasing last year's winner. The best-performing category in one year is frequently among the worst in the next, particularly for small caps and sector funds. Money flows in after the returns have already been earned, which is why investor returns lag fund returns so consistently.
Treating a new fund offer as an opportunity. An NFO is a fund with no track record priced at a nominal unit value that means nothing. There is no discount and no advantage. Existing schemes with a history are almost always the better comparison.
Confusing more funds with more diversification. Adding a seventh equity fund to a portfolio of six overlapping ones increases paperwork, not protection.
Redeeming during a drawdown. The single most costly action available, and the one most likely to feel responsible at the time.
Regulation has made it far easier to see what you own and what it costs. Whether you act on that is the part that remains entirely yours, and it accounts for more of the difference in outcomes than fund selection ever does.
