Options, grants, withholding, and gifts are context, not voluntary market purchases or sales.

Reported sales can reflect planned or tax-related transactions and do not by themselves indicate a view on the stock.

Purchase and sale labels describe reported transaction codes; they do not indicate whether the transaction is favorable.
