" the company can declare the figures “an earnings beat” and watch shares rise by much more than the lowered guidance cost them."
If the BTE earnings always cause the shares to jump by more than the lowered guidance takes them down, one might reasonably expect the stock to have advanced over the last ten years, no? And yet, the shares have NOT advanced over the last decade. In fact, these shares were north of $70 a little over ten years ago. Got any more of that "foolish" analysis to share with us?
