The day before the buyback was announced GFRE closed at $6.51 and went to 7.49 before closing at 7.31 on 9/27 the day of the PR. If it was undervalued then, it sure is now.
It climbed to +$10 without them having to buy any.
It's walk the talk time. If they planned to use stock for their next purchases, it should pay for itself.
