Insider Bought. What Did They Actually Buy?
The word \"purchase\" can describe several different insider transactions. The SEC filing shows how the shares actually moved.

"Insider bought" is a summary. The filing is the evidence.
Watch the video above, or read the evidence and reasoning below.
Previously, Before You Copy That Trade showed why a congressional disclosure needs its dates, range, and source context. This article turns to SEC Forms 3, 4, and 5. Next, Big Contract. Big Impact? examines another headline that can overstate what the underlying record establishes.
Situation: insider filings are public
SEC ownership filings can show transaction codes, share counts, prices, resulting holdings, ownership form, footnotes, and amendments. That makes them a valuable research source.
Complication: different events receive the same headline
An open-market purchase is different from an option exercise, stock grant, conversion, or transfer. One filing can contain multiple linked entries. Direct ownership can mean something different from holdings associated with a spouse, trust, or another entity. A matching acquisition and disposition may describe a transfer rather than new economic exposure.
Question: what did the insider actually do?
1. Identify the transaction type
Start with the SEC transaction code and the filing's footnotes. Do not assume every acquisition is an open-market purchase.
2. Follow the ownership
Check whether the filing reports direct or indirect ownership and whether it identifies a trust or other entity. Preserve the filing's language instead of inferring beneficial ownership beyond the evidence.
3. Reconcile the filing
Review the shares, price, resulting holdings, filing date, and any amendment. Related rows may only make sense when read together.
Resolution: organize the filing before interpreting it
Public Filings Intelligence organizes SEC Forms 3, 4, and 5, connects related entries, preserves provenance, and surfaces ambiguity that a sortable transaction table can hide. It helps investors move from a dramatic headline to a defensible question.
What this proved
The important question is not simply whether an insider "bought." It is how the shares moved, who owns them, what the transaction code means, and whether the complete filing supports the interpretation.
