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 $204K in the same 90 days, more than was bought (100% of it pre-planned).
- Similar past buys beat the S&P 500 only 46% of the time (1,159 cases); the typical one trailed it by 1.8%.
