Funds

2,407 series matching. One row per SEC series ID — the portfolio an investor actually buys into.

Fund (series)↕	Registrant↕	Ticker↕	Latest report↕	Net assets▼
iShares Broad USD Investment Grade Corporate Bond ETF S000013699	iShares Trust CIK 0001100663	USIG	2026-02-28	$16.99B

Amendments are applied. NPORT-P/A filings supersede the original for the same series and report date. Both rows are kept as filed, but every holdings figure here reads through holdings.v_latest_filing, which picks the surviving one. Joining the filing table directly would double-count amended months.

Not every fund can be reached. 1,193 of 5,620 ETF-family securities reach no series at all: commodity trusts (ETV) and notes (ETN) are not registered funds and have no series ID, and funds launched since the snapshot are not in it yet. "No holdings reported" and "cannot reach holdings from here" are different statements.
