545.77 is where it closed the day before the report for a drop of 57.46 or 10 1/2% as of today's close
I have seen drops greater than that on one bad earnings report. Not exactly what I would call a panic sell-off. But then again it may not be over yet. We shall see.
The company continues to have zero long-term debt, healthy sales growth, is nowhere near saturation, and guaranteed ongoing sales (& profits) on maintaining support and instrument sales to existing base of installed units. Any dip is a bargain, for years to come unless the fundamentals crumble, which shows no sign of happening any time soon. (I own no shares now, but have owned off and on ever since $42.00, and plan to own shares again soon.) The PE ratio is accurate for this company, and low based on a general historical range of (going by memory here) 35:1 to 45:1 or more, and the earnings kept right on a-growing, making it a bargain to have bought at those PE ratios. Do your own homework, and invest based on that. I do. Ignore the hype, chatter and mud-slinger epithets.
