Memory cycle has not peaked; valuations for Samsung Electronics and SK hynix remain cheap at 5-6x P/E versus global peers at 9-10x. HBM and AI demand continue to support earnings, and foreign selling is portfolio rebalancing, not a fundamental exit. The sector's extreme concentration creates short-term volatility but does not change the long-term uptrend.

Korean nuclear and electrical equipment names are seeing clear foreign buying even on a heavy down day, supported by a positive analyst report on Doosan Enerbility (CCL export strength and higher target price). The sector's relative resilience amid a broad selloff points to differentiated inflows and a favorable supply-demand backdrop.

KOSDAQ-listed semiconductor equipment and materials stocks (so-bu-jang) are rallying in sympathy with the major semiconductor names. These include Tech, PSK, TES, Wonik IPS, and others. The recovery in Samsung and Hynix provides lift to the entire supply chain, and order momentum (e.g., HBM-related) supports further upside.

MLCC (multi-layer ceramic capacitors) are entering a shortage phase driven by the rising cost share in NVIDIA's Vera Rubin platform. MLCC cost share jumped from under 10% (in GB300) to nearly 30% in Vera Rubin, and MLCC revenue grew 182%. This benefits Samsung Electro-Mechanics and LG Innotek directly, as they are key MLCC suppliers. The shortage narrative is similar to what happened with memory semiconductors, providing a strong demand tailwind despite elevated valuations.

Department stores (Shinsegae, Lotte Shopping), apparel (Handsome), and beauty/medical devices (PharmaResearch) are seeing strong sales. Handsome, in particular, is a late-cycle indicator as men's clothing purchases signal peak consumption.

This will likely trigger a governance restructuring, directly benefiting Hyundai Mobis (core parts affiliate) and Hyundai Glovis (logistics affiliate), which are key instruments in the restructuring.

Samsung Electronics and SK Hynix are expected to announce aggressive shareholder return programs. A DS report suggests Samsung preferred shares could offer up to 6.2% dividend yield in a best-case scenario, far above the normal 1%, making them attractive to foreign investors. SK Hynix is also anticipated to unveil shareholder returns as its quiet period ends. These catalysts could trigger a re-rating of the stocks.
