Summary

The January 21 pre-market show analyzed a sharp overnight US decline, volatile after-hours KOSPI trading, and whether Korean equities could rebound. Guests debated whether the selloff was driven mainly by Greenland/US-Europe geopolitical risk and bond yields rather than fundamentals. They favored semiconductors, energy/nuclear, storage, robotics, defense, and selective KOSDAQ rotation ideas while stressing risk management and avoiding leverage.

  • US and Korean markets fell on Greenland/US-Europe tensions, bond-yield spikes, and risk-off sentiment.
  • Semiconductor leaders Samsung Electronics and SK hynix were seen as supported by earnings expectations into January 29.
  • Energy, nuclear, natural gas infrastructure, and power equipment were highlighted as resilient non-semiconductor trades.
  • Storage names such as SanDisk and Seagate were favored for data-center-driven SSD/HDD demand.
  • Robotics and Hyundai Motor Group remained major themes, though some speakers warned of climax risk in Hyundai Motor.
  • Japanese insurers were pitched as rate-hike beneficiaries, while Korean hardware was favored over internet software.
  • KOSDAQ, cosmetics, entertainment, construction, and stablecoin-related names were discussed as rotation or event-driven ideas.
  • Several guests advised trimming high-beta winners, holding cash, and not using margin during elevated volatility.
Ideas
Park Hyun-sang Deputy Head 4:52
Buy semiconductors into January 29 earnings.
The recent KOSPI decline is driven by Greenland/Trump geopolitical risk and temporary foreign selling, not by semiconductor fundamentals. Foreign selling was small enough for retail buying to absorb, and Samsung Electronics and SK hynix should remain supported into the January 29 earnings season because HBM and memory pricing trends are still positive.
Park Hyun-sang Deputy Head 9:44
Rotate to Korean secondary batteries.
If the semiconductor-led market takes a breather, funds should rotate toward Korean secondary battery shares. The sector is oversold, KOSDAQ strength requires battery heavyweights, and the expanding robot narrative can also lift battery-related sentiment.
Park Hyun-sang Deputy Head 12:27
Buy KOSDAQ biotech after Samsung earnings.
Korean biotech may start moving after Samsung Electronics reports earnings. Historically, January-end KOSDAQ strength and biotech rallies follow the JP Morgan Healthcare Conference, with a second catalyst from AAC in March-April, and stocks with strong holders are already showing resilient supply.
Park Hyun-sang Deputy Head 13:33
Stay long Hyundai Motor Group.
Hyundai Motor Group remains a market leader because the auto sector has attached a concrete robot narrative. Domestic motor and actuator suppliers are receiving real inquiries, and if robot contracts or broader logistics/other robot applications materialize, the group can keep re-rating.
Park Hyun-sang Deputy Head 19:27
Buy cosmetics when Samsung stalls.
Korean cosmetics often act as a tactical rotation destination when Samsung Electronics is under pressure for two days. The sector moved when semiconductors stalled, making it a short-term place to watch for funds leaving large-cap tech.
Park Hyun-sang Deputy Head 23:23
Favor robot-exposed auto parts.
If autos continue higher, capital may rotate into cheaper auto parts names with even a small robot or actuator linkage. These parts stocks are less crowded, more supply-sensitive, and could attract institutional flows as a second-derivative robot play.
Park Hyun-sang Deputy Head 24:26
Buy Korean securities on volume.
Korean securities firms are a direct beneficiary of the market's elevated trading activity. Trading value has not yet fully peaked, and ongoing extended trading hours should support brokerage earnings and share prices.
Kim Tae-seong Division Head, Xangle 30:11
Trade copper for higher beta.
With geopolitical uncertainty around Greenland and US-Europe tensions, commodity prices are the clearest trend. Gold and silver have surged, but for trading purposes he prefers copper because it offers higher elasticity and better tactical expression than slow-moving safe-haven gold ETFs.
Kim Tae-seong Division Head, Xangle 35:06
Buy energy/nuclear infrastructure on dips.
Energy infrastructure, power equipment, cables, and nuclear are the safest non-semiconductor areas. They held up despite the selloff and should be bought on market weakness because real energy demand, cold weather, and nuclear buildout support earnings and order flow.
Kim Tae-seong Division Head, Xangle 36:24
Own Doosan Enerbility on gas turbines.
Doosan Enerbility is not just a future nuclear story. Its gas turbine business is already winning orders, giving it current earnings growth as well as nuclear optionality, which makes it attractive even if the broader market opens weak.
Kim Tae-seong Division Head, Xangle 36:56
Buy US natural gas infrastructure.
The cold wave has driven natural gas sharply higher, and US natural gas infrastructure companies should benefit. Long-term contracts mean producers and infrastructure owners can earn elevated margins when gas prices spike, and related equities already showed relative strength.
Kim Tae-seong Division Head, Xangle 37:56
Favor Korean valves and shipbuilders.
In Korea, the energy and natural gas theme can spill into fitting valves and shipbuilding as niche beneficiaries. These are less direct but can be tactical opportunities when energy infrastructure spending and LNG demand increase.
Kim Tae-seong Division Head, Xangle 38:55
Buy Nasdaq below 22,950 if calm.
If Europe's emergency meeting does not produce retaliatory tariffs, Nasdaq weakness below 22,950 points is a buying opportunity. If retaliation cards are played, investors should avoid trying to predict the bottom and wait through the weekend into next week.
Kim Tae-seong Division Head, Xangle 39:28
Buy storage on data-center demand.
Data center growth will require massive additional SSD and HDD storage, making storage hardware one of the strongest AI infrastructure expressions. SanDisk and Seagate are preferred over M7 names because their product demand should explode as data centers are built.
Kim Tae-seong Division Head, Xangle 43:43
Buy medical devices on recurring consumables.
Healthcare equipment and medical device companies are attractive because their high-margin recurring consumables create durable profit streams. In a volatile market, this consumables-driven model offered relative strength within Russell 2000 healthcare.
Kim Tae-seong Division Head, Xangle 45:14
Watch PharmaResearch rebound.
PharmaResearch is a Korean way to watch the medical-device consumables theme. It had already started rebounding, and because its business benefits from recurring consumable sales, the sector flow is worth monitoring even if Korea lacks many direct medical-device peers.
Kim Tae-seong Division Head, Xangle 47:43
Buy battery materials on lithium recovery.
Korean secondary battery materials and recyclers can benefit as lithium carbonate prices recover. Better lithium pricing improves inventory valuation into earnings season, supporting EcoPro, POSCO Future M, and recycling-related names such as SungEel HiTech.
Kim Tae-seong Division Head, Xangle 48:42
Buy Daewoo E&C on nuclear backlog.
Daewoo E&C is a cheaper nuclear construction implementation idea. Its nuclear and data center order backlog is increasing, and if Hyundai E&C and Samsung C&T valuations rise further, investors may look to Daewoo E&C as the next beneficiary in the nuclear construction chain.
Lee Ju-hyeon Director, Xangle 64:49
Watch POSCO International on Alaska LNG.
The surge in natural gas and cold weather keeps attention on the Alaska LNG project theme in Korea. POSCO International is a key related name to watch because it has direct exposure to the LNG project narrative while short-term gas theme stocks may be noisy.
Lee Ju-hyeon Director, Xangle 67:28
Buy entertainment on China thaw.
China-Korea cultural exchange and a possible Hanryeo easing should benefit Korean entertainment stocks. HYBE is the key name because BTS's overseas tour could generate multi-trillion-won revenue, and other agencies also have veteran artist comeback momentum in 2026.
Lee Ju-hyeon Director, Xangle 68:43
Buy cosmetics on earnings recovery.
Korean cosmetics are at a bottoming zone. Companies have continued to earn money and EPS has risen, but share prices are depressed, so the sector may gradually improve even if the recovery pace is slow.
Lee Ju-hyeon Director, Xangle 69:16
Watch hotel/leisure sector rebound.
Hotel and leisure names have been left behind as supply crowded into other sectors. Lotte Tour Development and Seobu T&D are among the beaten-down asset-like names that deserve renewed attention if sector rotation resumes.
Lee Ju-hyeon Director, Xangle 69:43
Stay long humanoid robotics.
Humanoid robots remain a core 2026 momentum theme. Atlas pricing could pay back within two years, Tesla targets about 50,000 Optimus units, and labor cost pressure from union demands is accelerating automation demand, so robotics momentum should continue.
Lee Ju-hyeon Director, Xangle 74:19
Buy Korean nuclear exporters.
Team Korea's nuclear export pipeline is strengthening through Vietnam, Turkey, Saudi Arabia, and the UAE. KEPCO is pushing a large Vietnam nuclear project with government financing, and the compressed large-nuclear beneficiaries should include KEPCO, Doosan Enerbility, and BHI.
Lee Ju-hyeon Director, Xangle 85:38
Buy defense on Western split.
US-Europe tensions over Greenland are splitting the Western alliance, which should push defense stocks higher. Even if military conflict is unlikely, trade conflict and alliance fragmentation increase the strategic importance of defense spending.
Lee Ju-hyeon Director, Xangle 94:04
Watch Samsung for time correction.
Samsung Electronics has reached a technical target and may enter a time correction rather than a price crash. If it breaks the 137,000-138,000 won support area, investors should see it as a cheaper buying opportunity because AI data center demand and semiconductor earnings are not structurally broken.
Lee Ju-hyeon Director, Xangle 113:52
Watch SK hynix at resistance.
SK hynix has been sideways since early January. If it breaks above the 145,000-146,000 won resistance, it can resume an upward trend; otherwise it may continue to rest while the market waits for earnings.
Min Jae-gi Team Leader, KB Securities Prime Club 120:04
Buy Japanese insurers on rate hikes.
Japanese insurance stocks are direct beneficiaries of rising Japanese government bond yields and fiscal expansion. Despite global bond-market volatility, Japanese insurers held up strongly, so they can be held as a hedge against the Japan rate-rise theme.
Min Jae-gi Team Leader, KB Securities Prime Club 122:59
Favor hardware over internet software.
Within Korean IT, hardware is stronger than software. Samsung Electronics and SK hynix are holding up relatively well while NAVER and Kakao are weaker, so investors should favor semiconductor hardware over internet software.
Min Jae-gi Team Leader, KB Securities Prime Club 122:59
Favor hardware over internet software.
Within Korean IT, hardware is stronger than software. Samsung Electronics and SK hynix are holding up relatively well while NAVER and Kakao are weaker, so investors should favor semiconductor hardware over internet software.
Min Jae-gi Team Leader, KB Securities Prime Club 128:44
Watch Hyundai Motor climax risk.
Hyundai Motor's trading value could be approaching a climax if it reaches 20-25% of KOSPI turnover, similar to past POSCO Holdings and secondary battery peaks. The stock has re-rated on robot and PBR themes without matching earnings, so a sharp trading-value spike should be watched as a warning.
Min Jae-gi Team Leader, KB Securities Prime Club 133:15
Buy SK Telecom on AI value.
SK Telecom is becoming a defensive telecom name with an AI value story because of its Anthropic stake. If Anthropic eventually lists, SK Telecom's stake value could be re-rated, while its low PBR and improving supply make it attractive in volatile markets.
Min Jae-gi Team Leader, KB Securities Prime Club 135:13
Buy Daewoo E&C valuation gap.
Daewoo E&C is cheaper than Hyundai E&C and is part of Team Korea's nuclear value chain, including the Czech nuclear project. With construction earnings depressed and nuclear orders improving, it is a valuation-gap trade within the nuclear construction theme.
Min Jae-gi Team Leader, KB Securities Prime Club 136:11
Watch regional construction recovery.
Korean regional construction companies are a contrarian recovery idea. Local real estate prices are being pulled up by rent and lease prices, unsold inventory is declining, and housing supply is falling faster than demand, so construction shares may bottom before earnings recover.
Min Jae-gi Team Leader, KB Securities Prime Club 139:18
Buy beauty laggards on bottoming.
Beauty laggards such as Silicon2 and Cosmecca Korea are showing relative strength after being neglected. Their fourth-quarter results may mark a bottom, and in a volatile market, beaten-down names with improving earnings can outperform.
Min Jae-gi Team Leader, KB Securities Prime Club 140:05
Watch Korean Air on pullbacks.
Korean Air is a watch-list name because asset value underpins it and it has not rallied much with smaller aerospace names. If market volatility pulls it back, its KF-21 and drone-related momentum becomes a more attractive study for re-entry.
Lee Kwon-hee CEO, Economist 145:43
Buy Samsung and SK hynix.
Samsung Electronics and SK hynix should not be sold. Memory semiconductor fundamentals are expected to stay strong through next year, the US memory complex held up during the selloff, and any correction driven by external risk is an opportunity to buy rather than a reason to exit.
Lee Kwon-hee CEO, Economist 154:27
Buy cosmetics and APR.
Korean cosmetics, including APR, are acting as a relative safe-haven within consumer names. Beauty stocks were strong even while the broader market fell, and the sector is attracting rotation demand from investors looking for non-semiconductor growth.
Lee Kwon-hee CEO, Economist 154:43
Watch stablecoin winners if legalized.
If stablecoin legislation passes, the main beneficiaries should be Kakao Pay and NAVER because payment and internet platforms could open the market beyond banks. This is an event-driven theme to watch rather than a confirmed trade.
Lee Kwon-hee CEO, Economist 161:59
Buy Hyundai Motor on robot story.
Hyundai Motor remains a core long because foreign investors have been under-owned and can be forced to chase, while short covering adds upside. The Boston Dynamics/Atlas robot narrative and group restructuring support a potential move toward 600,000 won, so pullbacks should be bought.
Lee Kwon-hee CEO, Economist 171:26
Watch KOSDAQ February rotation.
KOSDAQ may get a February rotation because the government's KOSPI 5,000 promise has been mostly achieved and policy attention could shift toward revitalizing KOSDAQ. If large-cap leaders enter a sideways period, funds may move into smaller KOSDAQ names.
Lee Kwon-hee CEO, Economist 171:40
Buy semiconductor equipment on investment plans.
Korean semiconductor equipment and materials stocks may become a buy around the January 29 earnings season. Samsung Electronics and SK hynix could announce investment plans with results, which would provide a catalyst for the domestic semiconductor equipment supply chain.
Lee Kwon-hee CEO, Economist 173:56
Buy KEPCO on pullbacks.
Korea Electric Power has become a stable nuclear and energy beneficiary as its PBR reaches around 1x. The stock is no longer cheap in the same way, but it remains attractive on pullbacks because nuclear exports and power demand keep improving its story.
Lee Kwon-hee CEO, Economist 175:13
KOSPI can reach 6,000.
The KOSPI can move beyond the 5,000-point target toward 6,000 because global demand for Korean companies has structurally increased and EPS growth is among the fastest in the world. Investors should not anchor to the symbolic 5,000 level.
