Kim Min-soo — CEO

Summary

In this interview, Kim Min-soo, CEO of Lemon Research, discusses a strong but crowded Korean market, then focuses on under-owned nuclear, power equipment, cable, and optical communications sectors. He sees strong nuclear news but weak timing and supply, favoring a watchful approach on large nuclear names and selected value-chain plays. He is more constructive on power equipment and transformer names given earnings, and highlights optical communications as an AI-driven theme, with Daehan Optical Telecom as a US-order beneficiary despite convertible-bond overhang.

  • Market is strong but crowded; high leverage, cash, and position concentration warrant caution.
  • Nuclear news flow is positive, but stocks lack momentum; orders and contracts are the key trigger.
  • Nuclear value-chain names discussed include Doosan Enerbility, Hyundai E&C, KEPCO, KEPCO E&C, KEPCO KPS, BHI, Woori Technology, Woojin, Bosung Powertech, and KNR Systems.
  • Power equipment and transformers are favored for earnings and grid buildout; Sanil Electric is a buy-on-dip idea.
  • Cable and wire names such as Daehan Electric Wire, LS, and Iljin Electric are presented as related watch or long ideas.
  • Optical communications is highlighted as an AI-era bottleneck solution because electrical signaling faces speed and latency limits.
  • Daehan Optical Telecom has US orders and expected revenue growth, but convertible bond supply may cap sharp rallies.
  • The host, Park Hyun-sang, frames the discussion around nuclear, power, cable, and optical communications.
Ideas
Nuclear orders key; wait for trigger.
Nuclear news flow is strong: the government is pushing two large reactors and one SMR, and overseas contract talk is building. However, the sector has not yet broken out because supply and positioning are poor and the timing is not right. The key trigger is visible orders or contracts, especially in the Middle East or Europe; until then, monitor rather than chase.
Doosan offers nuclear plus gas turbines.
Doosan Enerbility is a core nuclear equipment name, but its differentiated edge is the combination of nuclear exposure with LNG combined-cycle power and large gas turbines. Any broad energy or power plant buildout should benefit it, but the stock has already risen and supply and timing make chasing risky; watch for order catalysts.
Hyundai E&C is core nuclear EPC.
Hyundai E&C is one of the two key nuclear plays because construction and EPC capability are essential alongside main equipment. If overseas nuclear orders materialize, large EPC names are likely early movers; current news is good but the stock is already strong, so watch for entry rather than chase.
KEPCO benefits from nuclear cost cuts.
JPMorgan argues KEPCO is a power company, not a nuclear company, but nuclear expansion can lower generation costs while data-center demand increases electricity volumes. As a regulated monopoly with relatively low and lagged tariffs, KEPCO has a favorable cost-volume setup, though the stock has already risen.
KEPCO E&C designs nuclear plants.
KEPCO E&C is the nuclear engineering and design arm and should attract attention if nuclear projects move forward; the speaker flags it as a nuclear value-chain name with high interest.
KEPCO KPS is later nuclear mover.
KEPCO KPS, a nuclear maintenance and service name, is likely a later mover than equipment leaders; if the nuclear sector broadly runs, maintenance and service names may follow late.
BHI offers nuclear, LNG boiler exposure.
BHI has combined nuclear and LNG combined-cycle exposure, with strength in HRSG heat-recovery steam generators. As energy and power installations rise, its equipment niche should benefit; the stock is already strong and sector timing remains the risk.
Woori, Woojin lead nuclear instrumentation.
Woori Technology and Woojin are long-established Korean players in nuclear control systems and instrumentation; if nuclear orders come, they can win sole or scarce domestic roles, making them high-beta beneficiaries. The speaker cautions that speed may be tricky because they have already risen.
Bosung has nuclear steel certification.
Bosung Powertech is a steel-structure company with nuclear certification, so it gains attention when nuclear themes heat up. It has been moving already, making it a momentum name to watch rather than chase.
KNR Systems plays nuclear decommissioning robots.
KNR Systems is a nuclear decommissioning robot play. Decommissioning could become a large market, around KRW 25tn, but it is an early-stage and later-moving theme; if decommissioning orders materialize, KNR Systems should be highlighted.
Power equipment earnings support re-rating.
Any power plant buildout, whether nuclear, renewables, or LNG, requires transformers, transmission, and grid equipment, so power equipment is a broad beneficiary. HD Hyundai Electric and LS Electric reported good earnings and are re-aligning with the uptrend; ESS-specific transformers could add further upside.
Sanil Electric buy post-earnings dip.
Sanil Electric is a special transformer and ESS-exposed name with a good outlook, but the market expects a possible Q4 earnings miss. If earnings disappoint and the stock shakes out, the speaker prefers buying that dip rather than chasing strength.
Daehan Wire and LS attractive.
Cable and wire names are downstream beneficiaries of grid and power-plant construction. Daehan Electric Wire and LS have finally come into the speaker's target zone, so they are worth watching alongside power equipment.
Iljin Electric setup remains favorable.
Iljin Electric's technical setup is good within the power and cable-related space, making it a favorable watch or long candidate.
G&E Energy buy after consolidation.
G&E Energy is a smaller power-related name whose earnings and orders are trending up, but valuation debate makes it volatile. The speaker prefers buying only after speculative attention cools and the stock consolidates with low volume.
AI migration favors optical communications.
AI-era data centers and servers cannot keep scaling on electrical signals because speed and latency limits are binding; the answer is light and optical communications. This should drive optical modules, transceivers, and optical cabling as data centers and glass-substrate server architectures grow.
Daehan Optical has US revenue growth.
Daehan Optical Telecom is a direct optical-communications beneficiary with US orders already being installed; revenue is expected to grow about 220% this year. The main risk is a large overhang from convertible bonds, so sharp rallies may see supply; the speaker would trim into strength and look to rebuy.
