Context
Code F withholding often occurs when an executive exercises stock options or when restricted stock units vest and the company withholds shares to satisfy tax obligations. These withholdings are administrative/tax events and do not necessarily indicate the insider is selling shares on the open market or changing their view of the company. For retail investors, outright purchases are generally more informative about insider sentiment than routine tax-related withholdings.
