US Stocks Dataset ↗ · dataset updated 2026-06-25. Third-party informational snapshot. Individual observation times and price currency are not supplied. Not live market data. Descriptions may be truncated by the source. Snapshot price and market cap are shown in source units; currency is unspecified. These values do not replace the imported price history above.
All imported asset types, including options. Counts are disclosure rows, not unique investment decisions or proof of current ownership. Source aliases can produce more than one profile for the same person; profile counts are not deduplicated people.
Newest disclosure first. Fund increases/decreases compare snapshots; their exact trade dates are unknown. Reported amount ranges are preserved, not treated as exact invested sums.
119 matching records · page 1 of 4
Latest stored snapshots, not current holdings or purchase dates. Coverage can be stale or partial; portfolio weights and inferred investment totals are intentionally omitted.
No source-backed fund snapshot is stored for this symbol. Legacy illustrative holdings are excluded.
Coverage is limited to imported sources and symbol matches; ticker reuse, renamed securities and incomplete filings can affect history. The earliest imported reported transaction/snapshot date is 2013-12-27. A disclosure may describe a spouse, dependent or fund rather than a personal trade. Stock prices, token listings and these records do not establish an executable trade route. Live copying remains disabled.
