Ciena Corp is trading 5.5% down at $461.25 as investors continue to take profits following last week’s sharp post-earnings reversal.
- Despite the current slide, the company reported strong Q2 FY26 results with revenue and EPS beats and raised full-year guidance driven by booming AI cloud demand.
- Shares have been under pressure since June 3 as an extended buy-the-rumor, sell-the-news reaction and broader rotation out of high-multiple tech stocks unwind the prior AI-driven surge.
