Sector Logic: Computer Hardware & Peripherals

Data Storage (HDDs)

Growth Drivers: AI applications are driving exponential data storage needs, shifting demand structurally toward data centers. HDD manufacturers maintain capacity discipline, creating a structural supply shortage that provides OEMs with sustainable pricing power. Next-gen HAMR (Heat-Assisted Magnetic Recording) technology is scaling up, enhancing capacity and lowering costs, while long-term contracts with hyperscalers lock in persistent demand.

Market Outlook: The industry is undergoing a valuation paradigm shift from cyclical to quasi-consumer staples. Scenario analysis indicates structural earnings upside, with potential EPS for top HDD makers reaching $45. Under supply constraints and improving $/TB pricing, operating margins are expanding significantly, with recent reports showing record GAAP/non-GAAP margins surpassing 47%.

Recent Moves: Driven by record-setting quarterly financial metrics—including revenue growth of 44% YoY and massive free cash flow generation—storage stocks have seen multiple upward target price revisions. Market focus is now shifting from short-term beats to the sustainability of HAMR deployment, long-term contract visibility, and the ongoing de-leveraging and capital return story.

Active Electrical Cables (AECs)

Growth Drivers: As AI clusters scale, short-reach interconnects within data centers face power and reliability bottlenecks. AECs, which integrate retimer chips at both ends of a copper cable to regenerate signals, offer a reliability rate two orders of magnitude higher than optical modules and roughly 30% lower power consumption, making them a critical solution for AI backend connectivity.

Market Outlook: The market is poised for rapid volume expansion. Ethernet AEC shipments are projected to double from approximately 5 million units in 2025 to 10 million in 2026, with 800G as the mainstream form factor. Currently priced at around $500 per unit using a value-pricing model referencing optical modules, the next-generation 1.6T AECs are slated for release in 2026 to align with new computing platforms.

Recent Moves: The competitive landscape is taking shape around retimer chip performance, cost control, and customer certification moats. With nearly half of the AEC's bill of materials tied to the retimer chip, vertical integrators and system builders are racing to secure design wins. Investors are increasingly modeling future AEC penetration based on XPU installation volumes and network architecture shifts.
