In most Indian equity funds, the biggest bet is one of two banks

Two banks at the top

Every fund has one position larger than the rest. Across the 135 actively managed funds in SEBI's named diversified categories, that position is ICICI Bank in 53 funds and HDFC Bank in 25: 78 funds, or 58%. No other stock is the largest holding of more than three.

Mid-cap and small-cap funds are the exception by rule. SEBI's categories require them to invest most of their money outside India's hundred largest companies, so the biggest banks cannot lead them. Leave those 29 funds out and the two banks are the largest holding in 78 of the remaining 106: 74%.

Part of this is the benchmark. These two banks are the heaviest stocks in the indices large-cap funds are measured against: in the Nifty 50 portfolio of August 2026, HDFC Bank weighed 9.85% and ICICI Bank 9.45%. A manager who holds less of them than the index is making an active bet against them, so holding them near their index weight is the default.

But the split between the two is a choice. A fund holding both banks at their index weights would lead with HDFC Bank, the slightly heavier of the two. Instead ICICI Bank is the top holding in more than twice as many funds, 53 against 25: on balance, India's active managers are leaning towards ICICI Bank and away from HDFC Bank.

How big the biggest bets are

The median fund's largest position is 6.36% of its net assets. Thirty-four funds hold 8% or more in their top stock, and 24 hold 9% or more. Only two are above 10%: quant Mid Cap Fund in Aurobindo Pharma and DSP Large Cap Fund in ICICI Bank. SEBI's rules cap a scheme's investment in any one company at 10% of its net assets, with exceptions for index and sector funds, and a month-end weight can drift above that as prices move.

Six of the ten are bets on ICICI Bank. The others are the kind of conviction calls a fund house is known by: quant Mutual Fund holds Aurobindo Pharma at 9.5% to 10.5% of net assets in three different schemes.

How concentrated are the funds?

The median fund in this group holds 55 stocks and keeps 36.1% of its net assets in the ten largest. The spread around that is wide.

Six of the ten most concentrated funds belong to one fund house, quant Mutual Fund. The least concentrated sit at the other extreme: Nippon India Small Cap Fund spreads its money over 254 stocks and keeps 14.5% in its top ten; HDFC Large & Mid Cap Fund holds 240 stocks with 19.3% in its top ten. Two funds in the same SEBI category can therefore be very different products, which the category name alone does not tell you.

What it means if you own several funds

If you own a large-cap fund, a flexi-cap fund and a tax-saver, there is a good chance ICICI Bank is the largest holding in at least two of them. Across three funds that can add up to a bigger single-stock position than any one fund would take. The fund overlap tool shows how much two or three of your funds share, and every stock page lists all the funds holding it, ranked by weight.
