The significant and unusual part is not that they announced an open-ended buyback plan which is common as you mentioned, but that they announced a dutch-auction type plan where they committed 1/2 their cash to paying a minimum of $5.00 per share. Yet the price is at $4.80. People are selling for lower than what they would get in the plan.
I have about 40 graded cards. I expect they will still be there no matter what happens to the company that graded them.
In 10 years I'll be on part 44, one post per quarter
