Worth a closer look

- Raised their own holding by 33%.
- Their first purchase here in our data, after 1 sale.
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 44% of the time (339 cases); the typical one trailed it by 2.6%.
