10b5-1 plan lets them buy back during the black period. it would be absolutely retarded to back load buybacks when you think the company is undervalued. it would also be retarded to spread out your buy back through out the year when you think your company is undervalued.

This. If they feel that their business is strong, and the share price is going to rise, they will start buybacks sooner rather than later to save money. If they do something different then the CFO should start firing the analysts that work for him.
