Known data limitations

Form 4 lag: insiders have 2 business days to file after a trade (weekends and holidays extend this), and this site re-ingests once daily — a transaction can appear here roughly three business days after it happened.
13F lag: quarterly 13F-HR holdings cover the prior quarter-end and are due 45 days after it — every institutional position shown here is at least 45 days old by construction, often more.
CUSIP→ticker gaps: 13F positions are reported by CUSIP; some holdings cannot be matched to a current ticker (delistings, corporate actions, thin metadata) and appear without one or are omitted from ticker-level views.
EDGAR timing variability: institutions file at different hours and days within their windows; amended filings (4/A, 13F-HR/A) can restate earlier periods, so historical aggregates may change between batches.
