What Are Large Cap Mutual Funds Buying And Why?

Four of the 5 large cap mutual funds examined opened positions in National Stock Exchange of India in September 2026. But their portfolios reveal more than interest in a newly listed company. SBI kept adding Kotak Mahindra Bank shares, while ICICI Prudential reduced them. Nippon increased its ITC holding, while Mirae sold shares in the same company.

There is another revealing detail. HDFC Bank became a larger part of the HDFC and Mirae portfolios in September even though neither scheme added a single share. Understanding these differences helps investors read mutual fund portfolios without mistaking every higher allocation for fresh buying.

This analysis compares the complete physical equity portfolios of SBI, ICICI Prudential, HDFC, Nippon India and Mirae Asset large cap funds on July 31, August 31 and September 30, 2026. September was the latest common month verified from official AMC files during research on November 4. October portfolios were not located in the disclosure listings checked, so no October buying claims are made.

Which Stocks Are Large Cap Mutual Funds Buying?

The 5 large cap mutual funds managed a combined approximately ₹2.53 lakh crore at September end. These are selected major active schemes, rather than a verified ranking of the 5 largest funds. Their Direct Growth plans provide an investor-facing reference, while the underlying portfolios and assets below cover the whole scheme.

The table below identifies meaningful increases in shares held between August and September. These are net additions across the month, rather than a record of every purchase and sale made during it.

The scale of a change matters as much as its percentage. Valuing the additional Kotak shares at the September-end price gives SBI an estimated ₹408.66 crore increase, equivalent to approximately 0.78% of its September AUM. This measures the value of the net shares added at one reference price. It does not reveal what the fund actually paid.

The longer comparison also matters. SBI Large Cap Fund held 3.80 crore Kotak shares in July, 4.80 crore in August and 5.78 crore in September. Its holding increased 52.11% across 2 monthly intervals, making this a clearer accumulation pattern than a single increase in portfolio weight.

Why Might Fund Managers Be Adding These Stocks?

The portfolio files establish what changed, but generally do not explain individual trades. No stock-specific manager explanation for these additions was established in the official material reviewed. The business connections below are analytical interpretations, and results published after September are identified as later evidence rather than information that caused an earlier purchase.

Kotak offers a growth story with a margin trade-off. In its October 24 results, Kotak Mahindra Bank reported standalone September-quarter profit of ₹4,212 crore, up 29% from a year earlier. Net interest income, broadly the interest earned after interest paid, grew 16%. However, its net interest margin fell to 4.31% from 4.54% a year earlier, showing that faster growth did not eliminate pressure on lending profitability.

For investors assessing the September positions today, that creates a useful question. Can loan growth and improving credit costs compensate for a narrower lending margin? The September-end share price implied by the portfolio disclosures was approximately ₹417, or about 2.13 times the ₹196 consolidated book value per share subsequently reported for September. This retrospective valuation snapshot does not establish that Kotak was cheap, or explain the managers’ decisions.

Swiggy combines growth potential with continuing losses. Information available before September included its August 6 ambition to reach ₹10,000 crore in adjusted operating earnings by FY31. That was a management target, dependent on execution. Its June-quarter shareholder letter also showed quick-commerce contribution margin near break-even, while the segment still recorded an adjusted EBITDA loss of ₹778 crore. Contribution margin covers a narrower set of costs than overall operating profitability.

The later October 22 update showed food delivery adjusted EBITDA of ₹341 crore, but a quick-commerce adjusted EBITDA loss of ₹895 crore. The investment debate therefore involves the pace of growth, spending and eventual profitability. SBI opening a position and ICICI Prudential adding shares show willingness to hold that exposure, without proving agreement on a valuation or a profit timetable.

BEL provides exposure to defence execution and order conversion. ICICI Prudential Large Cap Fund increased its physical Bharat Electronics holding almost 5 times in September. BEL subsequently reported rounded standalone quarterly revenue of ₹7,291 crore and profit of ₹1,541 crore, against ₹5,764 crore and ₹1,286 crore a year earlier. Its order book stood at ₹68,717 crore on October 1, according to its October 30 release.

An order book represents work to be delivered, rather than revenue already earned. It can support business visibility, while execution delays, payment collection and margins still matter. There is also a portfolio qualification. ICICI Prudential disclosed a long BEL futures position in August that was absent in September, so the increase in physical shares overstates the increase in total economic exposure if the earlier derivative exposure is ignored.

Cipla shows why additions should not automatically be described as buying strong current earnings. Its October 27 consolidated results showed revenue of ₹7,404 crore against ₹7,589 crore a year earlier, and profit of ₹878 crore against ₹1,351 crore. India revenue grew 12%, but North America revenue declined. A potential recovery case therefore has to be weighed against actual earnings weakness, without claiming that this was ICICI Prudential’s reasoning.

NSE was the clearest shared new position. HDFC, ICICI Prudential, Mirae and Nippon disclosed NSE shares in September after reporting none in August. NSE held its IPO during September 17–21 and announced its listing on September 24. The timing makes new-issue participation relevant, although monthly portfolios cannot identify how much came through allotments or subsequent market purchases.

Owning an exchange provides exposure to trading, clearing and other market services. It carries risks from regulation, competition and changes in trading activity. These positions are therefore different from buying a broad index fund, and their September appearance alone provides no evidence of sustained accumulation or an attractive entry valuation.

Where Do Large Cap Fund Managers Agree and Disagree?

NSE was the only stock added by more than 2 of these funds in September. Several other companies attracted additions from 2 funds, but that overlap should be read alongside the scale and persistence of each position.

Source, official July, August and September 2026 portfolios. Three month-end observations establish 2 monthly changes, not 3 consecutive months of purchases.

Yet overlap is only part of the story. ICICI Prudential reduced Kotak by 15,86,284 shares in September as SBI and Mirae increased their holdings. Nippon India Large Cap Fund added 50 lakh ITC shares, while Mirae reduced ITC by 50,66,163 shares.

ITC illustrates why disagreement can be reasonable. Its November 2 statement reported 19% growth in consolidated FMCG–Others revenue and margin improvement, alongside continued cigarette volume pressure from higher taxes. Those are competing business developments, and this later update is context for investors reviewing the holdings. It cannot establish either manager’s September reasoning.

Nippon’s September market outlook discussed improving consumer demand and more reasonable valuations. That provides broad context for its consumer additions, including ITC, Hindustan Unilever and a new Dabur position. It was an AMC-wide view, rather than a confirmed explanation of those specific trades.

Does Buying More Shares Mean Stronger Conviction?

A fund can add a stock and still hold less of it than its benchmark. Conversely, an existing holding can become a larger active position without any trading. Looking at both share counts and benchmark-relative weights prevents these differences from being missed.

The following estimates reconstruct Nifty 100 weights from the official, same-date free-float market capitalisations of its Nifty 50 and Nifty Next 50 constituents. They are approximate because the source market capitalisations are rounded. The 3 funds below use Nifty 100 TRI as their benchmark.

Source, AMC September portfolios and NSE Indices September 2026 constituent market-capitalisation reports. Active weight equals fund weight minus benchmark weight. BSE 100 weights were not independently established for SBI and Nippon, so Nifty weights are not substituted for their benchmarks.

Mirae Asset Large Cap Fund bought 15 lakh Kotak shares in September and remained underweight this estimated benchmark allocation. HDFC held a much larger relative position, although its Kotak share count was unchanged. Neither observation reveals the manager’s motivation on its own.

HDFC Bank offers an even simpler example. HDFC Large Cap Fund held exactly 3,87,52,638 shares in both August and September, while its weight rose from 6.88% to 7.36%. Mirae likewise retained 4,61,44,484 shares as its allocation increased from 8.57% to 9.19%. Changes in prices and total fund assets explain why allocation percentages can rise without purchases.

What Do the Sector Changes Reveal?

The clearest common allocation changes were higher financial-services and healthcare weights, with lower technology and automobile weights across all 5 funds. However, those are changes in the value of portfolio exposure, rather than proof that every manager bought or sold those sectors.

The technology example is especially useful. A lower sector allocation can coexist with purchases of an individual company within it. The evidence supports selective portfolio changes, rather than a claim that all managers share one view of the economy or market.

Should Investors Copy What Large Cap Mutual Funds Buy?

Monthly portfolios are useful for understanding a fund’s behaviour, but they are incomplete instructions for building a personal stock portfolio. They do not reveal every trade, entry price, investment horizon or internal valuation estimate. Fund inflows, redemptions and derivative positions can also affect the interpretation of a higher physical share count.

Position size adds another constraint. SBI’s new Swiggy holding represented approximately 0.53% of its September portfolio. Copying that company with a large share of personal savings would create a very different investment, even if the stock name were identical.

For an existing fund investor, the next disclosure is more useful as a consistency check. Does the fund retain its investment approach, keep concentration within a range the investor understands, and explain important changes clearly? Holdings should then be considered alongside expenses, performance across market cycles and the amount of risk taken to earn those returns.

The next step is to watch whether October disclosures extend September’s additions, reverse them or simply leave holdings unchanged. Repeated share additions can establish a pattern, while business results help investors judge what that exposure now represents. Neither turns a professional manager’s portfolio into a ready-made personal buy list.
