Why CIEN dropped

Ciena reported a record Q3 (revenue and EPS both beat estimates handily) but gave Q4 revenue guidance that only matched, rather than beat, analyst expectations, and hinted gross margins might dip slightly — that "good but not great enough" outlook was enough to crater a stock that had run up hugely on AI-networking optimism.
