Ciena Corporation shares rose 13.94% to $441.54 on Wednesday as fiber-optic connectivity stocks advanced in sympathy with Lumentum Holdings Inc.'s stronger-than-expected fourth-quarter results. Lumentum reported earnings of $3.23 per share versus a consensus estimate of $2.97, while revenue reached $1.01 billion, ahead of the $987.89 million Street estimate and up from $480.7 million a year earlier. The company also issued first-quarter guidance above analyst expectations, fueling positive momentum across the group. The wider market was also firmer, with the Nasdaq up 0.86%, the S&P 500 gaining 0.29% and technology leading sectors with a 1.57% rise. From a technical standpoint, Ciena remained in a constructive longer-term trend, up 358.11% over the past 12 months and trading 22% above its 200-day SMA (simple moving average) of $360.70, although it was still 6.4% below its 100-day SMA of $470.28. In the near term, the stock traded 12.9% above its 20-day SMA of $389.87 and about 1% above its 50-day SMA of $435.78, while a bearish crossover, with the 20-day SMA still below the 50-day SMA, remained a caution signal. Key resistance stood at $485.50 and key support at $424.50, near the 50-day EMA (exponential moving average) of $428.04.
