Ideas
US chip equipment rebounding, trend reversing
US semiconductor equipment stocks are rebounding sharply from a steep correction. Lam Research, Applied Materials, and KLA rose strongly, and their charts are approaching or confirming trend reversals, helped by J.P. Morgan's upgraded wafer-fab-equipment growth forecasts.
SOX breakout supports semiconductor uptrend
The Philadelphia Semiconductor Index broke above the upper line of a converging triangle after a two-month consolidation, a technical resolution that points to a semiconductor uptrend reversal. This should support Korean semiconductor and AI-infrastructure-related names.
Nasdaq box breakout would lift market
Nasdaq remains in a box, but if it breaks above the box top after the SOX breakout, market momentum should improve broadly, including for KOSPI.
KOSPI likely breaks 60-day resistance
KOSPI has moved right up to its 60-day moving average. With Samsung Electronics and SK hynix likely to open strongly after the SOX breakout, KOSPI is likely to gap up and finally break above the 60-day line after roughly two months of range-bound trading.
Samsung, SK Hynix to end range
Samsung Electronics and SK hynix are likely to end their two-month range as SOX breaks out and semiconductor pricing strength persists; SK hynix ADR rose 2.4% and a strong open should lift both Korean semiconductor leaders.
KOSDAQ holds breakout, needs bio batteries
KOSDAQ has already broken above its 60-day moving average and is holding above it, but further momentum depends on pharma/biotech and secondary battery stocks contributing upside.
Buy Korean chip equipment and materials
Korean semiconductor equipment and materials names are regaining momentum, and investors who do not own them should consider buying. Both front-end and back-end processes look good, with front-end strength continuing and back-end improving in the second half; Jusung Engineering and Doosan Tesna are front-end names, while Hana Micron, SFA Semicon, Hanyang Digitech, and Intekplus are back-end beneficiaries.
Hold AI infrastructure leaders
AI-infrastructure-related companies remain a core holding area because semiconductor and equipment leadership is broadening and the market's next leg should stay concentrated in AI infrastructure.
Optical communications trend remains intact
Optical communications should continue to work; a sharp rally may cause a short pause, but that is a pullback, not a trend reversal. RF Materials is the only Korean vendor to Lumentum and a direct beneficiary of optical-communication growth with improving earnings, while RFHIC and Sungwoo Electronics are fundamentally substantial names.
CIBR breakout on AI security demand
US cybersecurity stocks have been strong as AI advances increase both cyber threats and security demand. The CIBR cybersecurity ETF is testing a breakout toward new highs, and further upside is plausible if the breakout succeeds.
Korean cyber stocks speculative, mostly avoid
Korean cybersecurity shares may move next week on AI-security headlines, but they are speculative theme stocks with weak competitiveness versus US peers. Only short-term traders should trade them; longer-term investors should leave them alone.
Power infrastructure outlook stays strong
Power infrastructure, cables, and electrical equipment should keep working as AI-infrastructure expectations build. LS Electric and Sanil Electric are in early turnarounds or breakouts, and Hyosung Heavy Industries, Iljin Electric, and Daewon Cable also have positive price action.
ESS momentum will return; prepare early
ESS shares the same momentum as secondary batteries. Batteries have been quiet, but ESS momentum will return, so investors should prepare in advance.
Fuel cell and SOFC names attractive
Fuel-cell and SOFC-related names are attractive within the power/AI energy theme; Doosan Fuel Cell and related SOFC companies are worth watching.
Korean robotics remains attractive
Korean robotics was strong early this week and then paused, but order flow remains solid and stock prices are holding up, so the sector still looks attractive.
Aerospace momentum intact after pullback
Korean aerospace and space stocks pulled back after a sharp rally as SpaceX weakened, but momentum is maintained and the charts are resting in healthy patterns; SeAH Besteel Holdings is also worth watching.
HD Hyundai Heavy is shipbuilding main
Shipbuilding stocks are still weak and better approached by waiting and preparing rather than chasing. HD Hyundai Heavy Industries is the main name in the sector and is sufficient as a representative exposure.
HD Hyundai Marine gains from engine expansion
HD Hyundai Marine Solution has the strongest share price among shipbuilders because HD Hyundai Heavy Industries announced engine-plant capacity expansion; as an MRO and repair/maintenance company, it should receive more work as that capacity expands.
MLCC sector recently looks okay
MLCC-related shares have recently been doing well, making the area a minor positive within the broader electronics-component market.
Large biotech bottoming; Alteogen still weak
Large Korean pharma/biotech companies appear to be forming a bottom, though the move is slow and Alteogen remains too weak. Investors can wait for the turn before acting, but early bottom-fishing is not unreasonable.

Prepare secondary batteries via L&F, Samsung SDI
The secondary battery sector should be prepared in advance; the speaker continues to focus on L&F and Samsung SDI as the core names.
SM best; HYBE weak; JYP bottoming
Entertainment shares have moved well and can act defensively during pullbacks. SM Entertainment looks best, JYP Entertainment appears to be bottoming, while HYBE is not attractive.

Energy defensive; WTI range-bound
WTI fell below $100 but remains inside the $90-$110 box; a meaningful oil breakdown needs a move below $95 and especially below $90. Geopolitical attacks could push oil back above $100, so refiners and energy names may keep swinging, but earnings improve through next year and one defensive energy holding is not a bad idea.
