Summary

Yoo Chang-hee, CEO of YooStar, shares his outlook and stock picks on a Korean investment show. He argues that August will be stronger in the second half, with KOSDAQ leading while Samsung Electronics and SK Hynix consolidate. He highlights several trading ideas across robotics, biotech, construction, shipbuilding engines, defense, and airlines, underpinned by specific catalysts and technical patterns. He advises investors to hold existing positions, focus on momentum, and avoid chasing random sectors.

  • KOSDAQ is outperforming and could challenge 1100–1200 by year-end; the 5-day moving average is key support.
  • Samsung Electronics and SK Hynix are cheap and building a base, aided by massive shareholder return plans; patience required.
  • SPG shows a bullish technical pattern and benefits from the robot theme highlighted by the UNITREE IPO.
  • Alteogen is the biotech leader with strong SC conversion data and earnings; it could lift the broader sector.
  • GS Construction rides Gangnam reconstruction expectations and a resilient technical pattern.
  • Shipbuilding engine makers (HD Hyundai Heavy, Hanwha Engine, STX Engine) gain from high-margin engine orders.
  • LIG Nex1 stands out in defense by recovering a negative earnings shock quickly.
  • Korean Air is a macro play on stabilising oil and a stronger won, with upside to mid-30,000 KRW range.
  • Overall market is stock-picking driven; sell-offs provide opportunities, but avoid random rotation.
Ideas
KOSDAQ leads, 1100-1200 target possible.
KOSDAQ is leading the market, showing relative strength against KOSPI. The guest argues that investors (except those trading Samsung Electronics/SK Hynix) should focus on the KOSDAQ chart, and if the KOSDAQ holds its 5-day moving average, it could challenge the previous high of 1100–1200 by year-end. The global equity backdrop is strong (S&P 500, Europe, Japan at all-time highs), which supports Korean risk assets, and KOSDAQ is the primary beneficiary of rotation.
Samsung/Hynix cheap, base-building, eventual upside.
Samsung Electronics and SK Hynix are in a bottoming/consolidation phase with limited downside. Valuations are cheap (PER ~4x for Hynix, ~3.5x for Samsung vs Micron 6-8x). Both companies are expected to announce massive shareholder return plans (Samsung up to 200tn KRW, Hynix 100tn KRW) that provide a floor and long-term catalyst. Once the stocks stabilise (expected within 1–1.5 months) and moving averages converge, they can break higher. Samsung is slightly preferred for new entries because its conference call communication was clearer.
Engine makers benefit from strong order margins.
Shipbuilding engine makers are seeing positive news flow: HD Hyundai Heavy Industries sold 30 units of 1GW-class engines for a data center power project, worth about 1 trillion KRW. Engine manufacturing enjoys operating margins of 40–50%. Hanwha Engine and STX Engine are also preparing similar capacity, so the engine sub-sector within shipbuilding can show relative strength.
Alteogen biotech leader, strong momentum, sector catalyst.
Alteogen is the leading biotech name, showing strong recovery after a sharp drop. Positive data on SC conversion rate (10.5%) for Keytruda and solid 2Q operating profit (60bn KRW) support a re-rating. The stock quickly reclaimed the gap-down area, indicating strong momentum. Alteogen's strength can lift other biotech stocks, and a lower interest rate environment provides additional tailwinds for the sector.
SPG in bullish pattern, robot IPO catalyst.
SPG, a robot reducer supplier, is exhibiting a bullish 'ascending three methods' pattern from a bottom. The upcoming UNITREE (Chinese humanoid robot) IPO is raising market awareness of the robot theme, which should benefit domestic robot component names like SPG. If the stock breaks through the current supply zone, it can advance further.
LIG Nex1 shows resilience among defense names.
Most defense stocks are still bottoming, but LIG Nex1 looks meaningful. Despite a negative earnings-related red candle, the stock recovered that loss quickly, indicating underlying demand. Among defense names, LIG Nex1 is the one worth watching for potential upside towards 100,000 KRW.
GS Construction rides reconstruction theme, momentum intact.
GS Construction has risen significantly but still has room to go higher on expectations for Gangnam reconstruction and government housing supply measures. The stock is showing a bullish technical pattern where it held the prior low during the recent market crash and is now challenging resistance. Continued policy momentum could provide further upside.
Korean Air benefits from oil and FX tailwind.
Korean Air is attractive because oil prices are stabilising and the KRW has strengthened (USD/KRW falling to ~1,410), which benefits airline dollar-denominated debt and fuel costs. Even though summer holiday season is ending, the macro setup suggests the stock should move higher, potentially to 33,000–35,000 KRW.
