Key numbers explained

• Price: 355.91 USD, down -3.43% today — the price is what one share currently costs; the daily change shows how the market re-priced it today.
• Market cap: 50.47B USD — the total value of all shares; this places Ciena among larger technology companies.
• P/E ratio: 79.8 trailing, 30.2 forward — the trailing P/E divides the share price by the last twelve months' earnings per share (4.46 USD); the forward P/E uses expected earnings, which is why it is lower.
• 52-week range: 133.67 – 637.51 USD — the lowest and highest prices over the past year, a wide range that signals substantial price movement.
• 52-week change: 166.3% — how much the price rose from one year ago to now.
• Revenue: 6.02B USD, growing 37% year over year — total sales over the trailing twelve months and how fast they increased.
• Margins: 10.9% profit, 18.1% operating — the share of revenue left after all costs, and after operating costs only.
• Dividend yield: 0% — Ciena pays no dividend, so returns come entirely from price changes; the dividend yield measures annual dividends as a percentage of the price.

Recent news

Headlines report that Wall Street has been aggressively upgrading several stocks, including a jump in Ciena shares following an Evercore ISI upgrade to Outperform.

What to watch

As a communication equipment maker, Ciena's results depend on telecom and cloud operator spending, so revenue growth (37% year over year) and order trends are key indicators. Its next earnings date is Sep 3, 2026. The stock's beta of 1.31 suggests it tends to move more than the overall market, and its high valuation multiples mean results relative to expectations matter. Broader technology sentiment — as seen in moves by peers like Motorola Solutions (MSI) and Cadence Design Systems (CDNS) — can also influence the share price.
