Method & sources

amcs.fund is built only from official sources. Nothing is estimated from third-party aggregators.

Portfolios

SEBI requires every mutual fund house to publish the complete portfolio of every scheme each month, within 10 days of month end. We fetch each fund house's own file (Excel or a zip of Excel files) from its website, detect the header row, and read every line that carries an ISIN: instrument name, ISIN, industry or rating, quantity, market value, % to net assets, yield and maturity where given.

• Scheme size is the disclosure's own “Net Assets” or “Grand Total” row, never a sum of holdings (which would double-count hedges).
• Cash & others is scheme size minus the holdings that carry an ISIN: TREPS, reverse repo, net current assets and margin money.
• Money is shown in ₹ crore (“L cr” = lakh crore). Disclosures state ₹ lakh; we divide by 100 once.
• Rows whose market value exceeds the scheme's own net assets are dropped as corrupt cells and counted.

Industry and fund house totals

Adding up every scheme counts some money twice. Fund house and industry totals remove it the way AMFI's monthly industry figure does; each scheme and category still shows its full disclosed size.

• Domestic fund-of-funds are left out of totals. Their money already sits in the schemes they buy; AMFI shows them for information only.
• Units of the same fund house's schemes held by its other schemes are removed: an arbitrage fund parking cash in its own liquid fund, or a multi-asset fund holding its own gold ETF. SEBI's monthly report excludes such inter-scheme investments. Units of other houses' funds stay in, as in AMFI's figure.
• Liquid and overnight funds are kept as disclosed. Money arriving on the first working day of the next month gets units at the month-end price, so it appears in the fund houses' month-end portfolios, while AMFI's month-end figure leaves it out. Our total can therefore run slightly above AMFI's (about 0.5% in September 2026) when that day is a working day.

Commercial paper

RBI requires every commercial paper issue and every secondary trade to be reported to CCIL's F-TRAC trade repository. We read its public issuance and trade reports each working day. Outstanding is every reported issue dealt on or before a date and maturing after it, at face value; a re-opened paper counts each time it is issued. Mutual funds are the only holders that disclose CP paper by paper, matched to F-TRAC by ISIN. Their holdings are month-end market values, slightly below face value, so their share reads a little low. Banks, insurers, company treasuries and foreign investors do not disclose holdings by paper, so they are shown together as the remainder, never estimated.

Issuer type comes from official registers, not from the name. An issuer is its ISIN issuer code, so group companies stay separate. Development banks are RBI's all-India financial institutions (NABARD, SIDBI, Exim Bank, NHB, NaBFID) and NCDC, the statutory lender to cooperatives. Housing finance, holding companies (core investment companies) and finance companies are the entities on RBI's lists of registered NBFCs and asset reconstruction companies, by the class RBI gives them; lenders that have since merged or closed come from RBI's list of cancelled registrations. Brokers are on SEBI's register of stock brokers. Everyone else is a company. Each type is checked against the stock exchange industry of the issuer's shares and reviewed where the two disagree; the reviewed decisions, with reasons, are in our data. Hover over a type in the issuers table to see its basis.

Buys and sells

A buy or sell is a change in the number of shares a scheme holds between two monthly disclosures, valued at this month's price. Changes in market value alone are never counted as flows, because they mostly reflect price moves. Flows are shown only where both months disclose quantities.

Classification

• Scheme category is AMFI's, matched from AMFI's daily NAV file. AMFI is moving to new category names; where a new name has no exact old equivalent we keep AMFI's wording.
• Instrument type comes from the ISIN structure (equity, commercial paper, certificate of deposit, debentures, government securities, T-bills, state loans) and, where that is ambiguous, from the disclosure's section heading.
• Sector is the SEBI/AMFI classification from the exchanges. Large/Mid/Small follows SEBI's rule (rank 1-100, 101-250, 251+ by full market cap), computed on current market cap, so it can differ from AMFI's six-monthly list near the cut-offs.
• Issuer groups every instrument an entity has issued using the issuer code inside the ISIN.

History & coverage

History goes back as far as each fund house still publishes its monthly files. Every file's month is taken from the date printed inside it, never from its name. A month counts as partial when the files we could read add up to less than 70% of the average AUM AMFI reports for that fund house that quarter; partial months are shown but flagged.

Source files

Every month links to the fund house's own disclosure files it was built from, and to each file's archived copy in the Internet Archive. Click a cell in the map, or pick a fund house and month.
