Worth a closer look

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

Reasons for caution

  • Bought by a 10% owner or investment firm, whose reasons often differ from an executive's.
  • Held indirectly (a trust, fund or family entity), so the economic owner isn't only the named insider.
  • Similar past buys beat the S&P 500 only 45% of the time (1,823 cases); the typical one trailed it by 1.8%.
