Summary

Park Se-ik reviews semiconductor, power equipment, and defense stocks after a sharp market sell-off. He argues that memory names Samsung Electronics and SK Hynix have become attractive as HBM pricing fears are overblown and Chinese competition is muted. He urges caution on HD Hyundai Electric due to margin pressure from product mix and suggests avoiding Hyundai Rotem over JV margin uncertainty, while viewing LIG Nex1 as a buy on strong export-driven margin expansion.

  • Memory stocks (Samsung Electronics, SK Hynix) plunged on HBM contract negotiation worries, but Park argues the impact is limited and production can shift to high-margin general DRAM.
  • Chinese memory maker CXMT’s effective market share is overstated due to technology gaps and slow equipment procurement, easing oversupply fears.
  • HD Hyundai Electric posted decent results but margin headwinds from distribution transformers and potential ASP normalization call for caution; wait for margin breakout.
  • LIG Nex1 is favored for its export order backlog driving revenue share from 26% to 45% and supporting margin expansion, unlike peers with JV risks.
  • Hyundai Rotem faces margin uncertainty from overseas JV assembly operations, and the stock has broken below its trading range, warranting avoidance.
  • The broad market sell-off has made many Korean stocks attractively priced, shifting focus from risk management to profit management.
Ideas

Memory sell-off overdone, buy Samsung, SK Hynix
The sharp sell-off in Samsung Electronics and SK Hynix on HBM pricing concerns is overdone. HBM accounts for only 10-15% of revenue, and the companies can shift wafer capacity from HBM to general DRAM, which currently enjoys 80% operating margin, sustaining profitability. Fears of oversupply from Chinese memory maker CXMT are exaggerated because equipment procurement is slow, effective bit output market share is well below wafer-input share due to technological gaps, and they have only recently turned profitable, constraining aggressive investment. With SK Hynix trading near 150,000 won, down from 298,000, valuations have become attractive, presenting a buying opportunity.

Avoid HD Hyundai Electric on margin risk
Despite robust order growth and long-term demand from US data centers, HD Hyundai Electric faces margin headwinds from product mix shift toward lower-margin distribution transformers and potential normalization of high ASP. Historically, the stock has seen severe multiple compression when operating margins retreated even slightly. With current OP margin at 25% and 2027 consensus only 28.6%, modestly above prior peak, the risk/reward is unattractive. Wait for a clear breakout above 27% margin before considering entry; near-term caution is warranted.

Buy LIG Nex1 on export margin expansion
LIG Nex1's strong export order backlog (60% of total backlog is export) will drive export revenue share from 26% to 45%, powering sustained operating margin expansion from 8.5% to over 10%. Unlike land-system makers facing JV margin uncertainty, LIG Nex1's domestic production for export ensures margin visibility. The recent sharp sell-off has created an attractive entry point for a defense stock with multi-year earnings growth and improving profitability.

Avoid Hyundai Rotem on margin uncertainty
Hyundai Rotem's operating margin has already peaked around 17-18% and is unlikely to improve further as overseas JV assembly projects in Poland and Peru introduce cost uncertainties that could erode margins. The company itself cannot provide clear margin guidance for JV operations, and the stock has broken below its multi-month trading range, signaling investor unease. Prefer to avoid until margin visibility improves.
