I'll say this, since Eric has to file with the SEC as an insider/BOD member, which he did mid Dec and again Tues, rest assured Jerry (Dad) has been selling too, but he is no longer an insider thus does not have to file. Once Jerry got below 5%, no more filings required.
This is not a secret that the trust has been selling.
It's not a matter of lack of confidence in the future of the company IMO.
Selling in small amounts over time does us a small favor.
