Retrospectively, the last year delivered a frustrating 8.3% decrease to the company's top line. The last three years don't look nice either as the company has shrunk revenue by 28% in aggregate.

Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now.
