Summary

The video examines US Treasury yields above 5%, expected Fed and BOJ rate hikes, oil above $100, and AI capex speed-control concerns. Park Ji-hun argues the KOSPI is near a box bottom and highlights October recovery potential in memory semiconductors, power equipment, cosmetics, steel, batteries, nuclear, and selected KOSDAQ tech. He also covers department stores, US consumer weakness, AI substrates/MLCC, HD Hyundai Heavy Industries, and biotech rate headwinds.

  • US 10-year Treasury yield above 5% and Fed/BOJ policy dominate macro.
  • Oil near $106-108 and AI speed-control talk keep volatility elevated.
  • KOSPI is framed as a 6,500-7,000 box with foreign accumulation possible.
  • Samsung Electronics and SK hynix earnings trust may recover from October.
  • HBM4 conversion lifts semiconductor post-processing test equipment demand.
  • Power equipment, cosmetics, steel, batteries, nuclear, and fuel cells are highlighted.
  • Department stores and US consumer stocks face weak demand and a Q4 watch.
  • AI substrates/MLCC and selected KOSDAQ names are tactical picks.
Ideas
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 9:12
KOSPI box bottom offers recovery setup
The KOSPI is near a box bottom around 6,500-6,600, where excessive selling is less rewarding. Growth fundamentals remain valid despite high rates, foreign investors may accumulate beaten-down large caps, and October could bring a trust recovery if semiconductor triggers strengthen.

China share shift benefits Korean suppliers
As the US and Europe try to reduce China's market share in EV and robot value chains, Korean suppliers may receive reflexive orders. Robotis in actuators and PCB companies BH and DKT are cited as potential beneficiaries to watch after the September 24 US-China summit.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 19:20
October memory trust recovery despite FX noise
Foreign investors are shifting away from the view that memory peaks in H2 next year. LTA contracts and DRAM/HBM supply conditions support medium-term earnings, while FX-driven EPS cuts are temporary noise. Samsung Electronics and SK hynix may recover earnings trust from October and gap higher on a semiconductor trigger.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 20:13
FX weakness may revive cosmetics exports
Cosmetics stocks had corrected but may recover as a weaker won improves export competitiveness. He expects a more positive setup from October-November and suggests split buying after the Chuseok holiday.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 20:18
Power contracts may restart sector rally
Power equipment stocks may rebound again as power-sector contracts restart, similar to semiconductor LTAs. Hyosung Heavy Industries' contract is a sign of renewed ordering, and although valuations are burdensome, export/FX conditions support the sector.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 21:04
HBM4 testing drives equipment orders
Samsung's Onyang fab conversion from commodity DRAM to HBM4 and a new Vietnam fab require far more burn-in/CXT testing. Samsung has ordered over 1,000 testers and SK hynix also needs them, benefiting DI, Exicon, KoMiCo, and Unitest with staged orders into 2027 and improving post-processing equipment earnings.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 32:20
Energy shortage favors fuel cell theme
Energy shortage remains a core theme, and fuel cells are still attractive. Doosan Fuel Cell is cited as a representative name within the Korean fuel-cell theme.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 32:27
CPO telecom equipment remains structural winner
CPO-related telecom equipment for data-to-data transmission remains part of a larger structural wave. Even with macro noise, these communication equipment stocks are showing strong price action and are not candidates for exclusion from the AI/energy buildout.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 37:22
Samsung SDI top pick on IRA
If Trump and Bessent lose persuasive power, anti-Trump sectors such as secondary batteries should be watched. Samsung SDI is the top pick due to IRA confirmation, early 2027 re-rating potential, ESS/prismatic exposure, and a sharp operating-profit turnaround; LG Energy Solution is also attractive for its sodium-ion preparation.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 39:05
Steel spreads improve on lower input costs
Steel stocks are underowned but improving: iron ore and coking coal prices are falling, reducing input costs, while distribution prices are rising to improve spreads. Hyundai Steel is attractive for its very low PBR in a high-rate environment, and SeAH Besteel Holdings and POSCO Holdings are also worth watching.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 40:00
ESS prismatic cans benefit Sangshin P
As Samsung SDI wins large prismatic ESS orders, cans are essential, making its value-chain can suppliers attractive. Sangshin P is named as a representative SDI ESS can supplier idea.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 42:31
Wait until Q4 to buy department stores
Korean department stores are weak now because inbound tourist demand is slowing and a weaker won reduces luxury shopping incentives. Third-quarter growth is decelerating sharply, so he would not buy now but would gradually buy from Q4 as consumption indicators potentially bottom.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 43:24
High mortgage rates hurt US consumers
US consumer stocks are showing earnings shocks because mortgage rates above 7% and depleted savings leave households with little spending capacity. The consumer discretionary backdrop is unattractive.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 44:52
AI substrates benefit from SOCAMM demand
AI substrate demand tied to SOCAMM and Vera Rubin is improving, while substrate stocks have consolidated for one to two months. Samsung Electro-Mechanics is viewed as attractive at current levels, and Simmtech and TLB are named as beneficiaries, requiring selective buying.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 46:32
Haesung DS gains from substrate leverage
Haesung DS has seen automotive lead-frame utilization reach full capacity, while its substrate business shows improving operating leverage and margins from Q3. Foreign investors have accumulated shares, and consensus into 2026-2028 is upward, making the recent move more than a technical bounce.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 48:57
MLCC price hikes lift earnings
Global MLCC peers such as Panasonic and Taiwanese makers have started raising prices, forcing Korean MLCC companies to raise prices by more than 10%. Customers appear to be accepting the increases, which should flow directly into earnings.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 52:16
HD Hyundai Heavy needs double bottom
HD Hyundai Heavy Industries needs a double-bottom confirmation after its post-capacity-expansion decline. If that bottom forms, downside should be protected because its recent LPG carrier orders show rising prices and qualitative growth even while broader newbuilding prices are stagnant.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 54:15
Nuclear must be included in rebound
Nuclear should be included among stocks that can rise again. The government is expected to brief on US investment, the 12th electricity plan may require new large nuclear and SMR capacity, and an APR1400 export of more than two units would be a surprise. Recent selling in Doosan Enerbility and nuclear equipment names such as KEPCO E&C may not be just a one-day sell-on.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 56:52
US biotech okay despite five percent yields
Even with 5% yields, US biotech is still not bad. The US biotech backdrop remains relatively resilient compared with domestic Korea biotech.
Park Ji-hoon Director, Asset Management Consulting Dept., NH Investment & Securities 56:59
Korean biotech cannot beat high rates
Domestic Korean biotech is not in an environment that can beat high rates. Even cash-generating platform names such as Celltrion, Alteogen, and Samsung Biologics are not moving much, and only companies with individual conference or pipeline catalysts may rebound intermittently. Broad Korean biotech exposure is unattractive while yields stay near 5%.
