Could it be the recent upgrade to BUY by Davidson (I believe they are the market maker in this stock)? New Product well received? The recent acquisition? Or maybe because they are considered an indicator company for the recovery as R&D expands using their products. Hmmmm. I'm holding on for this ride. I think it will be 16 again this year. I know that sounds unreasonable, but as someone else said, look at the chart.
