Shares of LuxNet and Alloptr surged to the daily limit as strong July earnings and rising AI infrastructure spending fueled investor optimism.

What Happened

Cloud Capex Surge: A recent Morgan Stanley report highlights that major cloud service providers, including Microsoft, Google, Amazon, and Meta, are expected to significantly increase capital expenditures through 2027. This massive investment in AI infrastructure is creating a favorable environment for Taiwanese optical communication suppliers.

LuxNet's Strong Performance: LuxNet reported a 60% year-over-year increase in net profit for July, driven by robust demand for high-speed AI optical communication. Analysts are optimistic about the company's growth, citing the mass production of 800G ZR modules and expanded capacity in its laser product lines, with revenue projected to grow 38% in 2026.

Alloptr's Strategic Focus: Alloptr also posted impressive results, with a 140% year-over-year profit growth in July. The company is focusing on CPO architecture and high-speed switch applications, with plans to enter mass production following client validation, positioning itself well for the AI data center market.

Institutional Buying: Driven by strong fundamentals, foreign investors have been actively accumulating shares in both companies. LuxNet has seen six consecutive days of foreign buying, while Alloptr has shifted from net selling to net buying, pushing both stocks to their daily price limits as institutional capital flows into the AI optical sector.
