Worth a closer look
- Open-market purchase with their own money (Form 4 code P), not a grant or option exercise.
- Bought by the CEO, one of the two people with the fullest view of the company.
- Raised their own holding by 16%.
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 47% of the time (163 cases); the typical one trailed it by 1.5%.
