How to find which mutual funds are buying a stock

To learn how to find which mutual funds are buying a stock, you work from the monthly scheme portfolio every Indian fund house must publish. Paragraph 6.1.1 of SEBI's Master Circular for Mutual Funds dated 20 March 2026 (read on 19 September 2026) sets the rule: AMCs disclose the portfolio, with the ISIN, as on the last day of the month for all their schemes, on their own website and on the AMFI website, "within 10 calendar days from the close of each month in a user-friendly and downloadable spreadsheet format". Debt schemes go fortnightly, within 5 calendar days of every fortnight, and carry the yield of the instrument. Calendar days, not working days, is the detail that sets your expected publication date. Compare one month to the next and the additions, trims and exits appear on their own.

Where does the data showing which mutual funds are buying a stock come from?

Paragraph 6.1.1 of the master circular is the whole answer. Every AMC discloses the portfolio, along with the ISIN, as on the last day of the month for all its schemes, on its own website and on the AMFI website, within 10 calendar days from the close of each month, in a downloadable spreadsheet. Debt schemes repeat the exercise fortnightly, within 5 calendar days of each fortnight, and include the yield of each instrument. The prescribed layout is Format No. 4C, which is why one scheme's spreadsheet lines up against another's: security name, ISIN, quantity, market value and percentage of net assets.

Paragraph 6.1.2 adds the push version. Unit holders with a registered email address are sent the monthly or fortnightly statement within the same deadlines, with a link to view or download only the schemes they hold, alongside the scheme risk-o-meter and the benchmark's risk-o-meter.

How much is on the other side of those spreadsheets: AMFI's monthly report for August 2026 counts 1,985 schemes across the industry, with net assets under management of INR 87,07,887.74 crore as on 31 August 2026.

A workflow to find which funds are buying a stock

1. Pull the monthly portfolios for the schemes you care about, or search across schemes for the stock's name.
2. Compare month over month. A position that is new, or larger than last month, means the fund added to it. A smaller or missing one means it trimmed or exited.
3. Note the as-of month on every portfolio before drawing any conclusion. The data reflects month-end and publishes up to 10 calendar days later.
4. Cross-check the shareholding pattern. A company's quarterly shareholding pattern names mutual funds holding above 1%, which is a second public view of large fund positions.

The limits to keep in mind

• The lag is real. Between month-end and the 10-calendar-day publishing window, a scheme can already have traded. This is a dated snapshot, not a live feed.
• The reason is not disclosed. The portfolio shows what changed, not why. A fund can add to a stock for many reasons, and the filing does not say which.
• Look for overlap. When several independent funds, or a fund plus known individual investors, hold the same name, that ownership overlap is a fact you can verify in the filings. The same discipline lets you track individual investors.

That is how to find which mutual funds are buying a stock: read the monthly portfolios, compare across months, and mind the date. Flock assembles this public disclosure data and keeps every holding stamped with its month and source. What it means for you is your call to make.
