AI memory
Samsung's Q3 operating profit jumped nearly ninefold year-on-year to roughly $80bn, driven by advanced AI memory demand — Nikkei's number, filed from Seoul on Oct 8. The company also earmarked 10.5% of the memory unit's profit for union bonuses and is spending $5bn to expand semiconductor operations in Vietnam. Micron sells into the same pricing backdrop and rose 4% in the prior session, now up 245% YTD on a 5.3x forward P/E. The whole trade rests on HBM pricing holding into Q4 — any supply catch-up resets it fast.
Buy Samsung Electronics — Nikkei's near-ninefold profit jump on AI memory demand, plus a locked-in union bonus deal, is the cleanest single read on the memory cycle we have this morning.
Buy Micron — Samsung's blowout confirms the pricing Micron sells into; MU rose 4% last session, is up 245% YTD, and still trades at 5.3x forward P/E — cheap only if memory pricing holds.
Buy Semiconductors — Record memory earnings at the largest maker is a sector-wide read on AI capex staying hot; SOXX sits 11% below its 52-week high after a 1.1% pullback last session.
Buy South Korea equities — Samsung is the KOSPI's biggest weight and the profit beat plus bonus payouts are a direct index tailwind; EWY is 17% below its 52-week high and up 80% YTD.
