what: 'US listed ETFs from iShares, SPDR, Vanguard, Invesco and Global X, each from the issuer''s own full holdings file. Beside them, 1,982 other US stock ETFs, listed under tickers_sec, come from their latest public SEC Form N-PORT filing, which describes the portfolio at a quarter end, usually two to four months back; each of their fund files gives that date as report_date. From the same filings: 924 fixed income ETFs (tickers_bond), 250 multi-asset ETFs (tickers_multi_asset) and 1,398 derivative-based ETFs (tickers_derivative). 131 trusts and commodity pools (tickers_trust) come from their own SEC filings. 140 funds from their sponsors'' own files (tickers_sponsor), too new for a Form N-PORT, are read from the holdings their sponsors publish on their own sites. 282 more (tickers_prospectus) have a file from their prospectus and no holdings yet.'
