[하우머니] K-반도체 역대급 실적에도 주가 박스권…앞으로의 변수는?

Summary

The program examined why Korean semiconductor stocks remained range-bound despite record earnings. Industry analyst Lee Ju-wan offered a notably bearish interpretation, arguing that recent earnings and export strength may overstate underlying demand and that the memory cycle could be near a peak. These are the analyst’s views, not independently verified conclusions.

Analyst’s Key Arguments

• Memory-cycle peak risk: Lee interpreted Micron’s guidance and declining margins as signs that the memory upcycle may have peaked. He said memory prices had stopped rising by September and could begin falling around the fourth quarter. He estimated there was a greater-than-90% chance that Samsung Electronics and SK Hynix were near their own peaks. The interview also referred to differing interpretations of Micron’s timing, so the exact quarter of a peak was not settled.
• Exports may reflect prices more than volumes: September semiconductor exports exceeded $60 billion, but Lee argued this was largely a price effect. He cited government data showing cumulative DRAM exports down 40% through August and what appears in the subtitles to be NAND exports down 60%; the latter figure is unclear in the transcript.
• Production cuts and utilization: Lee disputed companies’ claims about operating at full capacity. He cited utilization estimates of approximately 78–81%, saying the figures supported his view that production had been deliberately constrained. In his analysis, supply—not demand—is the main driver of memory prices and the memory cycle.
• AI and memory are separate issues: Lee argued that AI investment does not necessarily prevent a memory downturn. He questioned whether AI services can generate enough revenue to justify data-center spending and suggested the AI investment boom could face a reckoning next year. He described data-center investment as a roughly three-year spending cycle followed by a three-year payback period, while acknowledging uncertainty about whether the investments will earn adequate returns.
• Longer-term growth: He said semiconductor demand can continue to grow while its growth rate slows, as the industry moves from a high-growth phase toward a more mature one.
• China competition: Lee said China is already a competitive threat, not merely a future one. He claimed China accounts for 58% of global semiconductor demand and that Chinese semiconductor exports have exceeded Korea’s since 2019. He warned that Korean companies’ exposure to Chinese customers makes substitution by domestic Chinese suppliers a risk to Korean revenues.
• Materials and equipment: Lee said materials demand is tied more directly to production volumes, while equipment is tied to investment. Based on a cycle pattern he said he had tracked for about 10 years, he expected semiconductor-equipment makers’ performance to lag chipmakers’ by roughly one year—potentially making next year stronger for equipment firms if chipmakers peak this year.
• Valuation and foreign selling: Lee gave fair-value estimates of ₩70,000 for Samsung Electronics and ₩200,000 for SK Hynix, arguing that earlier share-price gains were bubble-driven and vulnerable if memory prices decline. He also cited continued foreign selling as consistent with his bearish view.

Framework and Data to Monitor

Lee recommended focusing on supply conditions rather than demand forecasts when assessing memory cycles:

• Track production, shipments, inventories, and operating rates in the semiconductor manufacturing industry.
• Check the monthly data on the KOSIS (Statistics Korea) portal and use spreadsheets to chart trends.
• Compare price movements with production and capacity utilization to assess whether supply is tightening or overshooting.
• Treat strong nominal exports cautiously: distinguish price increases from actual volume growth.

Other Developments Mentioned

• A reported antitrust lawsuit, described as filed on June 25, involving memory companies and alleged supply restriction. Lee expected litigation and possible appeals to take two to three years. The transcript says no final decision had been announced.
• Large technology buyers were reportedly signing long-term supply agreements. Lee viewed that as purchasing at current prices, rather than proof that future demand would sustain the cycle.
• The discussion mentioned Micron’s profitability, Samsung Electronics, SK Hynix, and Chinese memory producer CXMT. Some translated company or product references in the subtitles are unclear.

Assets and Companies Mentioned

• Companies/securities: Samsung Electronics, SK Hynix, Micron, CXMT, NVIDIA, TSMC, AMD, OpenAI, Anthropic
• Products/sectors: DRAM, NAND, HBM, semiconductors, semiconductor materials and equipment
• Other references: AI and data-center investment; foreign investors; exchange-rate effects
