Bounded public source preview, up to 25 disclosed events.
How to read the disclosure dates
The tables report different things: insider transactions, institutional positions and Congressional transaction ranges. Read each table with its source dates and units. They cannot be added into a combined ownership percentage.
Company insiders
SEC Form 4 purchases, sales and awards report transactions and their public filing availability.
Institutional managers
13F reports disclose delayed quarter-end positions. They are not a record of trades between quarters.
Congressional filers
Periodic transaction reports disclose transaction dates and amount brackets. Public filing dates determine what researchers could know.
Read the transaction codes
Awards use transaction code A, purchases P and sales S. An acquisition from an award is not the same as an open-market purchase. Joint filers may share a transaction. Use original receipts and availability dates to interpret the events.
