Instructions

TickerInside is an open, machine-readable database of US ETF holdings, with the source and date of each holding. It covers 5,404 US ETFs, 623 of them read daily from their issuers' own files and the others from their latest SEC filings or their sponsors' files, and 5,043 US stocks with a file. Its tools answer questions about an ETF's holdings, the overlap between ETFs, which ETFs hold a stock, what a portfolio of ETFs holds underneath, where its risk comes from, how an ETF's holdings changed from one file to the next, and which stocks the ETFs read daily bought or sold. Every answer includes the source file's date and a source link. Measurements, not investment advice.
