π§ Assessment
The strongest thread this hour is the memory chain: Micron’s 60k wafer/month HBM expansion targeting HBM4 12-high, plus Montage’s adoption at Samsung/Hynix and the 10-20% iPhone 18 price-hike view, reinforces the AI memory supercycle narrative β US memory names could see a catalyst tonight.
Tesla’s Cybercab milestone arrives with regulatory risk in tow: public rides are a key validation step for the Robotaxi story, but NHTSA’s review of the steering-wheel-free design keeps uncertainty over rollout pace.
All three geopolitical fronts (Russia-Ukraine civil aviation, Iran-Israel, Hormuz) are heating up but remain in “assessment/preparation” rather than action β oil is supported in the 89-90 range yet lacks a one-way driver; range-bound view holds.
Gold’s pullback to 4467 basically wipes out Asian gains; capital is standing aside pre-NFP, leaving direction to tonight’s 20:30 data, with two-way swings likely until then.
A-share pork limit-ups and HK property surge are theme-spread moves β the former has supply-shrink logic, the latter needs property sales data for confirmation; avoid chasing at emotional peaks.
