How to Check Form 4 Table I Against Table II

How to Check Form 4 Table I Against Table II is a practical workflow for turning raw filings into usable investor context. The goal is not to copy a famous holder or react to a headline. The goal is to ask whether the data shows a real change in ownership, a passive benchmark artifact, or a mechanical insider transaction.

Start with the right comparison set

Begin with the stock page, then compare it with related names. For a technology headline, that might mean Nvidia, Microsoft, Apple, Amazon, Meta, Broadcom, Vanguard, BlackRock, FMR. For a consumer or retail headline, it might mean AEO, WMT, TGT and NKE. The comparison set keeps one filing from becoming an unsupported thesis.

Next, separate holder type. Vanguard, BlackRock and State Street can dominate reported value because they represent broad market exposure. Active managers such as FMR or specialized funds may be more useful when you are looking for discretionary sponsorship.

Use share counts before dollar values

Dollar values move with price. Share counts reveal whether a filer actually added or reduced exposure. If NVDA rises sharply and a manager's reported value rises while shares are flat, the filing confirms exposure but not new conviction. If shares rise after a difficult headline, the signal is stronger because the manager chose to own more through the event window.

The same rule applies after market news. Record the headline date, record the next filing quarter, and compare shares. That gives you a clean before-and-after frame without pretending that every price move is a portfolio decision.

Check insider forms for mechanical activity

For Form 4 analysis, transaction code matters. An open-market purchase is different from an option exercise. A tax-withholding transaction is different from a discretionary sale. Table I and Table II also need to be read together, especially for founders, executives and multi-class issuers. The Jay Schottenstein profile is a good example of why a Table I line should not be turned into a total ownership claim without checking derivative or indirect holdings.

Build a repeatable checklist

A simple checklist works better than a dramatic headline. First, identify the event and the date. Second, open the stock page and record total holders, active top holders and top filer types. Third, compare share-count changes in the next 13F cycle. Fourth, check whether Form 4 or 13D/G filings add a second signal. Finally, compare the same pattern with related stocks so you know whether the move is company-specific or sector-wide.

This workflow is intentionally conservative. It will not turn every filing into a signal, but it will reduce false positives. That is the point of 13F Insight: use ownership data to find smart-money events, not spreadsheet noise.
