Stress Tests for Small Cap and Mid Cap Mutual Funds
Small cap and mid cap schemes in India publish a monthly liquidity stress test that answers one question: how many days would the fund need to sell 25% and 50% of its portfolio in an orderly way. SEBI pushed for this disclosure through AMFI in early 2024, after a long run-up in small cap valuations raised worries about crowded, illiquid positions.
The number is a liquidity gauge, not a prediction of loss. A fund that needs 30 days to sell half its portfolio is far more exposed to a redemption rush than one that needs 6 days, but neither figure tells you how much the fund could fall in a bad market.
Each AMC publishes the disclosure on its own website, and AMFI hosts a consolidated view, usually within a fortnight of month end.
What Days to Liquidate Actually Means
The calculation asks how long it would take to sell a slice of the portfolio without moving prices unreasonably, given how much each stock actually trades. AMFI prescribes a common methodology so numbers are comparable across fund houses, and it includes a few important choices.
- Pro rata selling: the test assumes the manager sells a proportional slice of every holding, not the easy ones first.
- Least liquid tail excluded: the bottom portion of the portfolio by liquidity is left out of the calculation, so the true worst case is worse than the printed number.
- Volume based participation: selling is capped at a fraction of each stock’s recent traded volume, with a limit on acceptable price impact.
- 25% and 50% thresholds: both are shown, and the 50% figure is usually more than twice the 25% figure because deeper selling hits thinner names.
Read the AMFI methodology note alongside the numbers, because the assumptions have been refined since launch and a change in assumptions moves every fund’s figure at once.
The pro rata assumption is the interesting part
Real managers do not sell pro rata under stress. They use cash first, then sell the most liquid large and mid cap names, which protects investors who redeem early and leaves the illiquid tail to whoever stays. That is precisely the fairness problem the disclosure is designed to make visible.
What Else the Disclosure Contains
The stress test is published with a set of companion metrics that matter just as much.
| Metric | What it tells you | What to watch for |
|---|---|---|
| Days to liquidate 25% and 50% | Portfolio liquidity under orderly selling | Rising trend month after month |
| Cash and equivalents | First line of defence against redemptions | Very low cash with high days to liquidate |
| Top 10 investor concentration | How much sits with a few large holders | Institutional money exits fast and in size |
| Top 10 stock weights | Single name concentration | Heavy weights in thinly traded stocks |
| Portfolio turnover | How actively the manager trades | High turnover in illiquid names |
| Valuation and volatility metrics | Portfolio price to earnings, beta, standard deviation | Comparison against the benchmark |
The combination is what matters. A scheme with 15 days to liquidate 50%, 2% cash and 35% of units held by ten investors is carrying a very different risk from one with 15 days, 8% cash and a purely retail SIP base.
How to Use This as an Investor
- Compare funds within the same category only. Small cap numbers are naturally worse than mid cap numbers.
- Track the trend for your own fund across six months rather than reading one month in isolation.
- Check whether AUM has grown much faster than the fund’s liquidity metrics. A larger fund in the same universe usually takes longer to exit.
- Note whether the AMC has capped lump sum inflows or limited SIP amounts, which is a manager signalling that new money is hard to deploy.
Fund houses have tools if redemptions spike. SEBI regulations allow a scheme to borrow up to 20% of net assets for up to six months to meet redemption needs, and there are separate provisions under which redemptions can be restricted in specified circumstances. Those are emergency levers, not routine ones.
The misconception to correct
A high days-to-liquidate number does not mean a fund is about to freeze your money, and a low one does not make a small cap fund safe. Liquidity risk and market risk are separate. A small cap scheme with excellent liquidity metrics can still fall 40% in a drawdown, which is the risk most investors actually experience.
Frequently Asked Questions
Where do I find my fund’s stress test result?
Every AMC publishes it monthly on its own website, and AMFI hosts a consolidated view across schemes. It is released within roughly a fortnight of month end. Search for the small cap and mid cap disclosure section rather than the standard factsheet.
Should I sell a fund with a high days-to-liquidate figure?
Not on that number alone. Read it with cash levels, unitholder concentration, AUM growth and the trend over several months, then judge whether the fund’s process still matches your holding period. If you are investing for ten years through SIPs, liquidity stress affects you far less than someone planning to exit in a year.
Do large cap and flexi cap funds publish stress tests?
The mandated monthly disclosure targets small cap and mid cap schemes, since those hold the least liquid stocks. Flexi cap funds with large small cap allocations carry similar risk without the same disclosure. Read their monthly portfolio and market cap split instead.
Why did every fund’s number change in one month?
Either market volumes shifted, or the prescribed methodology was refined. AMFI has updated assumptions since the framework began, and a change applies to all schemes at once. Check the methodology note published with the data before concluding your fund changed behaviour.
Key Takeaways
- Small cap and mid cap schemes disclose days to liquidate 25% and 50% of the portfolio every month.
- The test assumes pro rata selling and excludes the least liquid tail, so the real worst case is harsher.
- Read it with cash levels, top 10 stock weights and top 10 unitholder concentration.
- Compare only within a category and follow the trend across several months.
- Liquidity stress is not market risk, and a good score does not prevent a deep drawdown.
