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.
Reasons for caution
- Other insiders sold $9.1M in the same 90 days, more than was bought (64% of it pre-planned).
- Similar past buys beat the S&P 500 only 35% of the time (68 cases); the typical one trailed it by 3.0%.
- Reported 1 business day after the SEC's 2-day deadline.
