Oil may fall below ninety.
Trump is pushing a Middle East meeting to discuss ending the Iran war, and ceasefire reports are increasing. If WTI crude falls below $90, the speaker expects a significant rise in risk appetite, so the oil setup is bearish and event-driven.

CPU substrate makers benefit from hikes.
Intel and AMD CPU/GPU price increases should benefit Korean CPU/package substrate makers. The speaker specifically names Simmtech and TLB as companies related to CPU substrates that can see demand and pricing benefits.

AI chip demand remains very strong.
NVIDIA's Jensen Huang said chip sales could double next year, above NVIDIA's own 70% revenue-growth guidance, while Nebius raised GPU cloud prices up to 21% and AMD and Intel plan CPU/GPU price hikes. The speaker reads these as evidence of very strong AI demand and memory supply shortage, supporting the broader AI semiconductor supply chain including memory, AI servers, CPUs, and GPUs.
