Multicap vs flexicap: the same shelf, opposite mandates

A cousin forwarded me two funds last week and asked which one to buy.

Both were sitting under the same tab on his app. Diversified equity. Go anywhere. He was about to pick whichever one had the bigger return on the screen, which is what most people do.

I asked him one thing first. Did he know that one of those funds is required, by rule, to keep a quarter of his money in small caps every single day it exists, crash or no crash. And that the other one, on the same shelf, is free to hold none.

He did not. Most people do not.

Here is the part nobody reads. A multicap fund is boxed in by SEBI. At least 25 percent in large caps, 25 in mid, 25 in small. Three quarters of the book locked into a fixed shape. A flexicap has exactly one constraint. Keep 65 percent in stocks. After that the manager roams wherever he likes, and the floor under small caps is zero.

Now the detail that gives the whole thing away. Flexicap did not always exist. SEBI wrote the 25 in small caps rule in September 2020. Eight weeks later it opened the flexicap category, and most of the big fund houses converted their multicaps into flexicaps almost immediately. The thing they were escaping was that forced small cap sleeve.

So when a fund is labelled diversified, that word is doing almost no work. One version has to sit through every small cap drawdown with a quarter of your money. The other can dodge it, or double down, depending on one human's read of the market. Neither is automatically safer. But they are not the same fund, and the shelf will never tell you which one you are holding.

Read the mandate, not the tab.

Two mandates, as SEBI writes them

The current wording sits in SEBI's categorisation circular of 26 Feb 2026, which carries the 2020 rules forward. Side by side, the two categories are almost opposites.

Those size bands are the same ones NSE uses for its indices. The Nifty Midcap 150 holds the companies ranked 101 to 250, and the Nifty Smallcap 250 the next 250. So "a quarter in small caps" means a quarter of your money in companies ranked 251 and below.

The eight weeks that made the shelf

1. 6 Oct 2017SEBI standardises fund categories

   A multi cap fund had to be at least 65 percent in equity, with no size rule.

2. 11 Sep 2020Multi cap gets a fixed shape

   Circular on asset allocation of multi cap funds: 25 percent minimum in each size band.

3. 6 Nov 2020Flexi cap created

   A new equity category with only a 65 percent equity floor.

4. 26 Feb 2026Categories restated

   Both mandates carried into the updated framework.

The old multi cap rule from 2017 is, almost word for word, today's flexi cap rule. When the 2020 circular forced a small cap floor onto multi caps, the fund houses that did not want it had a new category to move into within eight weeks.

What a quarter in small caps does in a bad year

Size bands do not fall together by the same amount. NSE's own factsheets show the difference in day to day risk.

Now a worked example. Say in a bad year large caps fall 10 percent, mid caps 20 and small caps 30. These are round numbers, not a forecast, but the order is typical of a risk off year.

• Multi cap at its floor, with the free quarter in large caps: 50 percent large, 25 mid, 25 small. The fall is 5 plus 5 plus 7.5: about 17.5 percent.
• Flexi cap leaning large: 80 large, 20 mid, nothing small. The fall is 8 plus 4: about 12 percent.
• Flexi cap leaning small: 40 large, 20 mid, 40 small. The fall is 4 plus 4 plus 12: about 20 percent.

Same "diversified equity" tab, a range from a 12 percent fall to a 20 percent fall, decided by one weight the label never shows. A 20 percent fall needs a 25 percent climb to get back. That is the number to know before the bad year, not during it.

Why neither is automatically safer

The multi cap's floor cuts both ways. It forces the fund to hold small caps through a crash, but it also forces it to hold them before a small cap rally, when a cautious flexi cap manager might have sat out. Over the five years to 30 Sep 2026, NSE's factsheets show 14.51 percent a year for the small cap total return index, the Nifty Smallcap 250, against 6.38 for the Nifty 50. A fixed quarter in small caps was paid for that ride.

The flexi cap's freedom also cuts both ways. Its size mix is one person's market view, and it can change between factsheets. If you hold one, the monthly portfolio is the only place to see which fund you own this month.
