Summary

The video examines how liquidity rotation after single-stock leveraged ETF regulations lifted KOSDAQ and semiconductor materials/parts/equipment names. Park Se-ik gives a deep fundamental breakdown of TCK's near-monopoly SiC ring business for high-layer 3D NAND and estimates valuation upside. Im Director adds TCK chart and Samsung SDI relative-strength analysis; Dr. So Hyun-chul argues Samsung SDI is fundamentally better than LG Energy Solution.

  • KOSDAQ saw liquidity shift after restrictions on Samsung Electronics and SK Hynix single-stock leveraged ETFs.
  • Semiconductor materials, parts, and equipment led weekly KOSDAQ gainers.
  • TCK's SiC ring business is analyzed as a high-layer NAND consumable near-monopoly with tight inventory.
  • TCK valuation scenarios suggest upside in base and bull cases, with downside risk from delayed fab investment.
  • Technical analysis favors buying TCK on pullbacks toward 200,000-230,000 KRW.
  • Samsung SDI is identified as the secondary-battery sector leader over LG Energy Solution.
  • Fundamental arguments for SDI include no overhang, Samsung Display stake value, prismatic strength, and earnings turnaround.

Liquidity rotation favors KOSDAQ strongly.
After the July 31 financial regulator restrictions on Samsung Electronics and SK Hynix single-stock leveraged ETFs, liquidity rotated toward KOSDAQ. KOSDAQ trading value increased, credit burden fell from about 11 trillion won to the 5 trillion won range, institutions and individuals bought aggressively, and KOSDAQ rose 24% over four trading days.

Semiconductor materials/parts/equipment sector is leading.
Among KOSDAQ 200 and KOSDAQ 150 stocks that rose more than 8% this week, 122 names were concentrated in semiconductor materials, parts, and equipment. The rotation showed semiconductor materials/parts/equipment as the strongest area, followed by cosmetics, robots, biotech, power equipment, and secondary batteries.

TCK's SiC ring monopoly benefits NAND.
TCK is a near-monopoly maker of SiC rings used in semiconductor etch and deposition, especially essential for high-layer 3D NAND. It holds 70-75% share, with competitors entering lower 100-layer segments while TCK dominates 200-layer and 300-layer-plus production with a 2-3 year technology gap. SiC rings are recurring consumables replaced about every 15 days, high-layer NAND increases chamber count and shortens replacement cycles, inventory is only about 0.7 months, and 2026-2027 volume/ASP estimates support P and Q growth. Valuation scenarios show about 25% base-case upside and 60% bull-case upside, with downside to about 209,000 KRW if fab investment delays.

Buy SDI, the secondary battery leader.
Samsung SDI is fundamentally better than LG Energy Solution. SDI has prismatic battery leadership, a seven-quarter earnings turnaround, no large overhang from its largest shareholder Samsung Electronics, and a 15.2% stake in Samsung Display worth over 10 trillion won that can be monetized to fund future investment. LG Energy Solution is weighed down by potential overhang from LG Group's stake, so the better secondary-battery leader to own is Samsung SDI.
