Key Takeaways:
Shares of Lumentum Holdings Inc. (LITE) surged over 7% on Monday as investors piled into optical communication stocks, betting on accelerating demand for high-speed networking components driven by the buildout of artificial intelligence infrastructure. The rally, which also lifted peers like Applied Optoelectronics Inc. (AAOI) and Credo Technology Group Holding Ltd (CRDO), underscores the critical role of optical transceivers in the AI supply chain.
"The transition from 800G to 1.6T optical modules is acting as a clear inflection point, with LITE’s revenues accelerating," Zacks Investment Research said in a recent report. The firm noted that Lumentum is now in the “lead pack” of suppliers as customers move to 1.6T networks.
Lumentum reported a 65% year-over-year increase in revenue to $665.5 million for its second-quarter fiscal 2026, largely driven by its cloud transceiver business. The stock has gained 133.3% year-to-date, and analysts recently increased the average price target by 10.52% to $840.44. However, its forward price-to-sales ratio of 13.06x is more than double the industry average of 6.2x, according to Zacks.
The surge in Lumentum's stock highlights a broader investor bet on the AI infrastructure boom extending beyond just chipmakers like Nvidia Corp. (NVDA). With the transition to 1.6T networking gaining momentum, companies that can deliver these high-speed optical components are poised for significant growth, though lofty valuations are becoming a key concern for investors.
The market for high-speed optical components is becoming increasingly competitive. While Lumentum is benefiting from the current demand surge, it faces stiff competition from Coherent Corp. (COHR) and Applied Optoelectronics.
Coherent recently secured a multi-year strategic agreement with AI-chip giant Nvidia, which includes a multi-billion dollar purchase commitment for Coherent's laser and optical products and a $2 billion investment to expand production. This partnership solidifies Coherent's position as a key supplier for AI data centers.
Meanwhile, Applied Optoelectronics is also capitalizing on the demand for its 400G and 800G products. The company has also been diversifying its supply chain, reducing its reliance on China to less than 10% for its 800G and 1.6T components.
