Ownership literacy
Read the transaction, not the color.
Form 4 data becomes useful only after decoding transaction codes, ownership type, footnotes, planned-sale programs, derivative securities, and the executive’s remaining exposure.
Economic size
Compare transaction value with compensation, net worth, prior trading, and remaining holdings.
Cluster activity
Independent purchases by several insiders can carry more information than one isolated action.
Timing context
Map activity around earnings, guidance, trading windows, vesting, and pre-arranged plans.
Gross-sale bias
A large sale can leave an executive with substantially more economic exposure than before an option exercise.
Footnote blindness
Indirect ownership, trusts, family entities, and 10b5-1 plans often live in footnotes.
Selection bias
Memorable insider wins are easier to recall than routine or poorly timed transactions.
Classify the code
Identify acquisition or disposition, security type, price, and ownership form.
Read every footnote
Check plan adoption dates, tax mechanics, trusts, vesting, and derivative terms.
Calculate net exposure
Measure shares before, shares after, and the change in beneficial ownership.
Compare history
Inspect at least several years of behavior before calling an event unusual.
