No wonder I didn't see this PR on Yahoo finance recently. It appeared in 2013, not 2015. So, the only thing that appeared last Tuesday was the Cox piece, on Mauldin Economics (for subscribers only).
I should have caught this right away but didn't. Would have helped if a date had been provided. After reading the post I started thinking back over the events of 2015 and concluded that even though Dr. Boniuk has made a number of purchases this year on the open market, a new $7MM from him didn't add up.
