Part 1. US Market Focus and Insights

§1 Sub-industry Themes

Analysts' earnings upgrade momentum this week is clearly concentrated in the semiconductor equipment, key components, and materials sectors that support AI infrastructure. Market focus is extending from chip design giants to the entire manufacturing and Advanced Packaging ecosystem. The Leader on the list, TTM Technologies (TTMI.OQ), a leader in high-end printed circuit boards (PCB), reflects the strong demand for high-density, high-layer count PCBs in AI servers. Simultaneously, Onto Innovation (ONTO.N), focused on semiconductor process control, and Knowles (KN.N), a micro-acoustic solutions provider, also received significant upgrades. The former benefits from inspection demand in advanced processes, while the latter may ride the trend of specification upgrades in edge AI devices. Overall, the market is actively rotating into the "arms dealers" of the AI hardware supply chain that were previously less noticed but are vital, expecting their profitability to accelerate alongside the expansion of AI capital expenditures.
