What is AUM (Assets Under Management)?

AUM (Assets Under Management) is the total amount of money a mutual fund scheme manages on behalf of all its investors. A ₹20,000 Cr AUM fund holds ₹20,000 crore of investors' money, valued at current market prices. AUM moves for two reasons: markets rising or falling, and investors putting money in or pulling it out — a growing AUM isn't automatically proof of skill.

Is a bigger AUM better?

It depends heavily on the category:

• Large-cap & debt: a big AUM is usually fine — even good. It signals trust, spreads fixed costs (SEBI's fee slabs mean a lower expense ratio at scale), and these markets are liquid enough to absorb large positions. The biggest large-cap funds in India run well past ₹50,000 crore without obvious strain.
• Mid-cap: workable at scale, but watch for the portfolio quietly drifting toward larger names as the fund grows.
• Small-cap: a very large AUM can be a handicap. Small-cap stocks trade thinly, so a huge fund moves prices against itself when it buys or sells, and may be forced to hold 80–100 stocks or park money in large caps just to stay invested. Some of the best small-cap funds have periodically stopped accepting lumpsum money precisely for this reason — a sign of discipline, not weakness.

The other end: too small

Funds under roughly ₹100–500 crore carry their own risks: expenses spread over a small base, key-investor concentration (one large exit hurts everyone), and a higher chance of the scheme being merged or wound up. Tiny AUM plus a short track record is the classic profile of funds that quietly disappear.

A worked intuition

Imagine a ₹40,000 crore small-cap fund wanting a 2% position — that's ₹800 crore in one stock. In a company with only ₹2,000 crore of freely traded shares, building that stake would take weeks and push the price up against the buyer the whole way. The same trade is trivial for a ₹500 crore fund. That mechanical friction, not manager skill, is why size drags returns in small caps.

How to use AUM on Dhanik

Treat AUM as a sanity filter, not a ranking signal: avoid the extremes — very tiny funds anywhere, and bloated funds in small-cap. Between those bounds, judge funds on returns, consistency, risk and cost. You can see and sort AUM for every scheme, and check a fund house's total AUM on its AMC page.
