The stress test your smallcap fund has to publish every month

Since 2024 small and midcap funds must disclose how long it would take to liquidate a quarter and half the portfolio — the only published redemption-risk number.

The risk that distinguishes a smallcap fund from a largecap one is not that the stocks fall further. It is that when many holders redeem at the same time, the fund has to sell the same thin stocks into the same falling market, and the selling itself moves the prices it is selling at. No return chart shows this. Since 2024 there is one published number that speaks to it directly, in a common format across every fund house, and it is updated every month.

Think of it like this
Eight hundred guests, one gate

A wedding hall is rated for 800 people and has one usable gate. On an ordinary evening nobody notices, because guests leave in ones and twos over three hours. The gate only matters on the night everybody decides to leave at once — and that is not a fact about the guests, it is a fact about the gate, which was measurable the whole time.

In the market

The stress test measures the gate. It asks how many days of ordinary trading volume it would take to sell a quarter, and then half, of what the fund owns. On most months the answer is irrelevant. It describes the one month when it is not.

What is actually published

From March 2024, every small cap and mid cap fund must publish a liquidity stress test within 15 days of each month end, in a format standardised by AMFI so that the numbers are comparable across fund houses. The headline is a pair of figures in days. Around them sits a set of disclosures that are arguably more useful, and that most coverage ignores.

  • Days to liquidate 50% of the portfolio, and separately 25%, computed on a pro-rata basis across holdings.
  • Investor concentration — the share of the fund's assets held by its largest investors. A fund where the top holders own a large slice can face a redemption that no retail pattern would produce.
  • Valuation against the benchmark — the fund's price-to-earnings and price-to-book set beside the Nifty Smallcap 250 or Midcap 150, so you can see whether the manager is paying above or below the index for the same category.
  • Portfolio composition across large, mid and smallcap, plus cash. A smallcap fund holding a quarter of its assets in largecaps and cash is a different proposition from one that is fully invested down the curve.
  • Volatility of the portfolio and the benchmark, and the fund's size, which is the variable that most directly drives the liquidation figures.

How the number is built

The method, in four moves
  1. 1
    Drop the least liquid fifth

    The bottom 20% of the portfolio by liquidity is excluded before anything is computed. This is the single most important thing to know about the figure: the hardest-to-sell part of the portfolio is not in the headline number.

  2. 2
    Assume you can only take a share of each stock's volume

    For each remaining holding, the calculation assumes the fund can sell only a fixed proportion of that stock's recent average daily traded volume without disrupting the price, using trailing three-month data.

  3. 3
    Sell pro-rata, not best-first

    The test sells across the portfolio in proportion, rather than dumping the liquid names first. That is the conservative assumption — a manager under real pressure would sell the easy stock first and be left holding the difficult ones.

  4. 4
    Report the days for 25% and 50%

    The output is two numbers. Because the divisor is trading volume and the numerator is fund size, the same strategy in a bigger fund necessarily produces a longer number.

Worked example
Two smallcap funds with almost identical three-year returns
Illustrative, using figures within the range the category has disclosed
Fund A: assets under managementMid-sized for the category₹4,200 crore
Fund A: days to liquidate 25% / 50%Could raise a quarter of the portfolio inside a week3 days / 6 days
Fund B: assets under managementAmong the larger funds in the category₹28,000 crore
Fund B: days to liquidate 25% / 50%Over a month to raise half, in an orderly market13 days / 27 days
Fund B: top-10 investor concentrationFewer decisions needed to produce a large redemptionHigher than Fund A
Three-year returnsThe return chart shows none of the aboveWithin a percentage point of each other
These two funds look the same on every screen that ranks by return. They differ on how long it would take to convert the portfolio into cash if a large share of holders wanted out together — which is not a prediction that anything will go wrong, but it is the size of the gate, and it is the one number the performance table cannot carry.

What the number does not tell you

  • It assumes an orderly market. The trailing three months of volume are the input. In the week when everybody wants out, volumes in exactly those stocks are not what they were in the three months before.
  • It excludes the worst 20%. That exclusion is deliberate and disclosed, and it means the true tail is quieter in the report than in reality.
  • Pro-rata is not how anyone behaves. A manager meeting redemptions sells what is liquid, which leaves the remaining unitholders with a more concentrated and less liquid portfolio than they had.
  • A short number can be bought. Holding more cash and more largecaps shortens the days figure and also makes a smallcap fund less of a smallcap fund. The composition disclosure beside it is what tells you which is happening.
  • It is not a forecast and not a rating. No number here says a fund will face redemptions, and nothing in the disclosure is a view on the manager. It measures one specific structural risk, and only that one.

Simple bhasha mein
Hall bada, darwaza chhota

Shaadi ka hall hazaar logon ka hai aur nikasi ka darwaza ek. Bhare hue hall mein yeh dikkat nahi lagti — dikkat tab dikhti hai jab sab ek saath uthein. Smallcap fund ko har mahine batana padta hai ki portfolio ka 25% aur 50% bechne mein kitne din lagenge — return chart yeh kabhi nahi dikhata, aur asli farak yahi hai.

What to remember
  • Small and midcap funds publish a liquidity stress test monthly, in a common AMFI format.
  • The headline is days to liquidate 25% and 50%, computed pro-rata on trailing volumes.
  • The least liquid 20% of the portfolio is excluded before the number is calculated.
  • The figure scales with fund size, so compare a fund with its own history rather than with rivals.
  • It measures the exit, not the returns — and equity funds cannot side-pocket or swing price.

Common questions

Short, direct answers to what people ask about this topic.

what is the liquidity stress test for smallcap funds
It is a monthly disclosure, mandatory for every small cap and mid cap fund since March 2024, showing how many days it would take the fund to liquidate 25% and 50% of its portfolio on a pro-rata basis. AMFI standardised the format so the figures are comparable across fund houses. Alongside the two headline day counts sit investor concentration, portfolio composition across large, mid and smallcap plus cash, valuation against the benchmark, and volatility.
where can I see my smallcap fund’s stress test result
On the AMC’s own website, published within 15 days of each month end in the AMFI-standardised format, with AMFI also collating the category. It is free and needs no login. Because the format is common across fund houses, the same two day-counts — 25% and 50% of the portfolio — can be read side by side, though the more informative comparison is a single fund against its own figure a year earlier.
the days to liquidate figure in a mutual fund stress test is driven mainly by
The size of the fund measured against the traded volumes of the stocks it holds. The arithmetic is close to linear in assets under management: double the AUM with the same portfolio and the same market volumes and the days roughly double. That is why the numbers cluster by fund size rather than by manager skill, and why they say nothing about stock selection or about future returns.
how much of the portfolio is left out of the stress test calculation
The least liquid 20% of the portfolio is excluded before anything is computed — the exclusion is deliberate and disclosed, and it means the hardest-to-sell holdings are not in the headline number at all. Two further assumptions soften it: the calculation uses trailing three-month volumes, which are not the volumes available in a week when everyone wants out, and it sells pro-rata rather than liquid-names-first, which is not how a manager under real pressure behaves.
does a high days to liquidate number mean a fund is bad
No — the figure measures one structural feature, how long the portfolio would take to convert to cash under heavy simultaneous redemptions, and it is neither a forecast nor a rating. Nothing in the disclosure says a fund will face redemptions or expresses a view on the manager, and a short number can itself be produced by holding more cash and more largecaps, which makes a smallcap fund less of a smallcap fund. Read it beside the composition disclosure, the way you would read an evacuation plan rather than a weather forecast.
