Worth a closer look

  • Open-market purchase with their own money (Form 4 code P), not a grant or option exercise.
  • Raised their own holding by 10%.
  • 3 different insiders bought in the last 90 days.

Reasons for caution

  • 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%.
  • Their past buys: only 1 of 5 beat the S&P 500.
