Is 'Light In, Memory Out' Becoming the New Trading Narrative in the U.S. Stock Market?
Is "Light in, Memory out" Becoming the New Narrative in U.S. Stock Trading?
Following the growing market consensus that AI chip valuations may have peaked, capital is seeking the next AI-related theme. In this context, the "Light in, Memory out" narrative is emerging – signaling a shift where optical communication stocks are taking the baton from memory.
Optical communication, utilizing light signals (primarily via fiber optics) for data transmission, is critical for AI. AI model training and inference rely on massive GPU clusters that require frequent exchange of vast data, generating immense east-west traffic. Traditional copper interconnects face physical limits at high speeds (short distances, high power, interference). Optical interconnects solve this with higher bandwidth density, longer reach, and better energy efficiency, becoming crucial for scaling AI clusters.
The narrative is validated by diverging stock performance. While memory stocks (like Micron, SK Hynix) have corrected amid crowded positioning and growth concerns, optical communication stocks (AAOI, COHR, LITE) have surged roughly 40-50% since August, driven by strong earnings and accelerating demand from AI cluster expansion and the transition to 800G/1.6T technology.
LITE’s recent earnings solidified the story, beating estimates with impressive margins (gross margin above 50%, operating margin 36.4%). Its guidance projected an operating margin near 40% next quarter, faster than expected. Management noted laser capacity remains insufficient to meet strong demand and confirmed its key CPO (Co-Packaged Optics) client is accelerating plans.
COHR's upcoming earnings are highly anticipated for further confirmation. However, risks are evident after the sector's sharp rally. The current dilemma is believing the narrative while avoiding buying at a peak. In a thematic rotation market, survival is key – prepare your tools before deciding how to position.
