Powertech

Issue 004: Powertech (TWSE:6239). A real AI-packaging chokepoint that was priced for a flawless ramp. A cohort selloff has now put the price inside our accumulate zone. Our call: Accumulate (starter) at NT$266.5.

TOWA

Issue 006: TOWA (TSE:6315). A two-session chip-cohort selloff took the shares down 17.9% to ¥2,791, before a partial recovery to ¥2,848. The gap to fair value has closed part-way; we still hold, and wait for a better price. Our call: HOLD, medium conviction.

Everyone's right about SK Hynix. That's the problem.

Issue 002: SK Hynix (KRX:000660). We are the house bulls on memory, and we are not buying it here. The chokepoint is real, the moat is melting, and the price already pays for the peak. Our call: ACCUMULATE, patient.

TE Connectivity: the cheaper half of the AI-connector duopoly

Issue 003: TE Connectivity (NYSE:TEL). The number-two connector in the one duopoly AI cannot route around, trading at a 43% discount to its twin and below its own ten-year average. The catalyst is a re-rating. Our call: BUY, medium conviction.
