Ciena is trading at $440.60 (down 4.4%) as it extends a selloff driven by valuation concerns and profit-taking following its recent earnings report.
- Although the company posted strong fiscal 2026 results with revenue and EPS beats and raised guidance, investors are locking in gains following a massive prior rally.
- Market sentiment is being weighed down by concerns over high valuation multiples and potential supply chain constraints.
- Today's move appears to be a continuation of the post-earnings repricing phase rather than a reaction to fresh fundamental news.
