Ciena (NYSE: $CIEN) Surges After Strong Q4 ResultsCiena Corporation (NYSE: CIEN) delivered a strong fiscal fourth quarter and full-year 2025 performance, underscoring its critical role in high-speed connectivity and the rapidly expanding AI-driven infrastructure cycle. Revenue for Q4 came in at $1.35 billion, up 20% YoY, while full-year revenue grew 19% to $4.77 billion. Profitability also improved, with adjusted EPS rising to $0.91 for the quarter and $2.64 for the full year, both significantly above 2024 results.
The growth was primarily fueled by sustained demand from hyperscalers and service providers, particularly within Ciena’s Networking Platforms division. Optical Networking revenue climbed to $929.2 million, while Routing and Switching surged to $118.4 million, reflecting strong enterprise and cloud onboarding trends. Ciena’s strategic acquisition of Nubis Communications bolstered its high-bandwidth optical capabilities, expanding its positioning within the AI ecosystem—where data center interconnect (DCI) demand continues to accelerate globally.
The company also executed a shareholder-friendly $329.7 million share repurchase program during 2025, signaling confidence in long-term cash flow strength. Looking ahead, management forecasts FY26 revenue between $5.7B and $6.1B, supported by durable cloud demand and expanding AI network infrastructure. Ciena expects continued margin stability, with non-GAAP gross margin guided around 43%.
Technical Analysis
The chart reflects a strong bullish structure. CIEN has been riding a clean ascending trendline for months, with the latest earnings surge triggering a breakout to new all-time highs near $248. Price now trades well above the 9-day SMA, confirming strong momentum. Volume expansion supports the breakout, indicating institutional participation.
If the uptrend holds above the $220–$230 support zone, CIEN may target the next psychological levels around $260–$280. RSI remains elevated but not overextended, suggesting momentum continuation. Only a breakdown below the trendline would signal cooling.

Double-Top Coming For Ciena?Based on historical movement, the trough could occur anywhere in the larger red box. The final targets are in the green boxes. The pending top should occur within the larger green box as has been the historical case. Half of all movement has ended in the smaller green box. In this instance, the signal indicated BUY on February 15, 2022 with a closing price of 68.53.
If this instance is successful, that means the stock should rise to at least 69.51 which is the bottom of the larger green box. Three-quarters of all successful signals have the stock rise 8.261% from the signal closing price. This percentage is the bottom of the smaller green box. Half of all successful signals have the stock rise 17.521% which is the end point of the black dotted arrow. One-quarter of all successful signals have the stock rise 27.504% from the signal closing price which is the top of the smaller green box. The maximum rise on record would see a move to the top of the larger green box. These are the same concepts for the levels in the red boxes as well.
The ends/vertical sides of the boxes are determined in a similar fashion. The peak of the rise can occur as soon as the next trading bar after signal close, while the max rise occurs within the limit of study at 35 trading bars after the signal. A 1% rise must occur over the next 35 trading bars in order to be considered a success. Three-quarters of successful movement occur after at least 9 trading bars; half occur within 20 trading bars, and one-quarter require at least 31 trading bars.
The black dotted arrow represents median historical movement. Medians are a good metric, but they are just one of many I use when forecasting future movement.
As always, the stock could decline the very next bar after the signal without looking back (therefore the red boxes would not come into play) or the stock may never decline (and the green boxes may never come into play).
