Worth a closer look

  • Open-market purchase with their own money (Form 4 code P), not a grant or option exercise.

Reasons for caution

  • Other insiders sold $13M in the same 90 days, more than was bought (15% of it pre-planned).
  • Bought by a 10% owner or investment firm, whose reasons often differ from an executive's.
  • Small next to what they already own (holding up 0.6%).
  • Similar past buys beat the S&P 500 only 46% of the time (1,159 cases); the typical one trailed it by 1.8%.
