Summary

Lim reviews the September 11 Korean market after KOSPI fell 1.76% and broke below 7,000, while KOSDAQ fell 1.95%. He focuses on support and resistance for Samsung Electronics and SK hynix, relative strength in MLCC, power equipment, nuclear, cosmetics, and shipbuilding names, and warns on stocks that have lost their 5-day or 60-day moving averages.

  • KOSPI broke 7,000 and KOSDAQ stayed directionless as foreign and institutional investors sold.
  • Samsung Electronics and SK hynix are the key index drivers, with the 60-day average and 1.8 million won level in focus.
  • MLCC stocks led the market, led by Samwha Capacitor, on AI and EV/autonomous driving demand.
  • Nuclear leader KEPCO E&C was compared favorably with relative laggard Doosan Enerbility.
  • Shipbuilding, power equipment, and cosmetics showed selective strength, while many names remain capped by 60-day averages.
  • Stocks that broke their 5-day moving averages, such as Alteogen and EO Technics, were flagged as weak.
  • The speaker advises tracking strong relative-strength names and using moving averages as support/resistance guides.
Ideas
Lim Learning Department Manager, Chesley 1:08
KOSPI needs Samsung-Hynix upturn
KOSPI broke below 7,000 and lost its 5-day moving average, but it held the 10- and 20-day averages and intraday buying appeared from the opening low. For a broader uptrend, Samsung Electronics and SK hynix need to turn upward; until then the index is a support/resistance watch.
Lim Learning Department Manager, Chesley 3:21
Samsung capped by 60-day resistance
Samsung Electronics fell 3.5%, breaking its 5-, 10-, and 20-day averages, and remains capped by the 60-day moving average. It is trading in a 240,000-280,000 won mini-box, and KOSPI needs it to break the 60-day resistance before a real uptrend can resume.
Lim Learning Department Manager, Chesley 4:32
SK hynix must hold 1.8M won support
SK hynix fell 2.2% but held above the 1.8 million won level, which turned into support after the September 9 breakout. It is important that it does not fall back below 1.8 million won; holding that level keeps the upward setup alive, while 1.56 million won is the lower support.
Lim Learning Department Manager, Chesley 5:40
HD Hyundai Heavy gains on engine investment
HD Hyundai Heavy Industries rose 5% and reclaimed its 5-, 10-, and 20-day averages with rising volume after a July 29 low. The market reacted positively to news that HD Hyundai will invest 1 trillion won in engines, suggesting investors are giving the news a favorable score.
Lim Learning Department Manager, Chesley 6:38
Alteogen trapped below broken 5-day
Alteogen has been unable to reclaim its 5-day moving average since breaking it on August 31, and the 5-day line has turned into resistance. The failed trend means the stock may need a long time to repair, so it is unattractive to own for now.
Lim Learning Department Manager, Chesley 7:10
EcoPro names capped by 60-day average
EcoPro fell 2.8% and EcoPro BM fell 7%, with both capped by their 60-day moving averages. The 60-day resistance is blocking a rebound, so the group remains in a weak technical position.
Lim Learning Department Manager, Chesley 7:23
Jusung Engineering holds 5-day uptrend
Jusung Engineering had a volatile day, reaching +3.8% intraday before closing down 5.4%, but it remains above its 5-day moving average and has not broken its uptrend. The stock is preserving a strong trend despite the weak market.
Lim Learning Department Manager, Chesley 7:38
EO Technics breaks 5-day support
EO Technics broke below its 5-day moving average and closed down 2%, ending the prior uptrend support. The break of the 5-day line is a negative technical signal for the stock.
Lim Learning Department Manager, Chesley 7:48
LS Electric capped by 60-day average
LS Electric fell 6% and remains capped by its 60-day moving average. Until it breaks that resistance, the stock lacks the strength to turn upward.
Lim Learning Department Manager, Chesley 8:20
Hyosung Heavy blocked by 60-day
Hyosung Heavy Industries fell 1.2% and is still blocked by its 60-day moving average. The stock needs to clear that resistance before it can move higher.
Lim Learning Department Manager, Chesley 9:28
Gaon Cable holds 5-day uptrend
Gaon Cable is in an uptrend, rose 1.6%, and has not broken its 5-day moving average on a closing basis. The stock is signaling that it wants to keep the 5-day support intact and should be watched.
Lim Learning Department Manager, Chesley 10:17
PSK Holdings holds 5-day trend
PSK Holdings is a semiconductor equipment name that rose 1.29% in a weak market and has not broken its 5-day moving average. It is digesting overhead supply from a double-top pattern, and the intact 5-day trend keeps it strong.
Lim Learning Department Manager, Chesley 11:14
HPSP tests key 10-day support
HPSP fell 4% and broke its 5-day moving average, but its key support is the 10-day line, which has repeatedly held. It is up 94% from its low, so the 10-day moving average is the level to watch for whether the strong trend survives.
Lim Learning Department Manager, Chesley 12:00
Simmtech consolidates while holding 5-day
Simmtech fell 2% but has not broken its 5-day moving average, and it is consolidating below a mini-box resistance near 134,000 won. The stock is conserving strength while it works through supply.
Lim Learning Department Manager, Chesley 12:53
Samwha Capacitor leads MLCC surge
Samwha Capacitor surged 18%, reached +27% intraday, and saw heavy volume with foreign and institutional net buying. As an MLCC-related name with a 1.4 trillion won market cap, it is attracting concentrated buying on the AI and EV component demand theme.
Lim Learning Department Manager, Chesley 13:30
MLCC demand grows with AI and EVs
MLCC-related stocks led the market as analysts highlighted expanding MLCC demand from AI acceleration and growth in autonomous driving and electric-vehicle electronic components. The sector has a positive demand narrative and strong market leadership.
Lim Learning Department Manager, Chesley 13:47
Amotech is high-beta MLCC play
Amotech hit the daily limit-up as an MLCC-related stock, and its small market cap of about 280 billion won makes it move more lightly than larger peers. The stock offers a high-beta expression of the MLCC theme.
Lim Learning Department Manager, Chesley 14:08
Samsung Electro-Mechanics is MLCC proxy
Samsung Electro-Mechanics is the representative MLCC stock and closed flat despite the sector's strength. If the market and MLCC cycle turn, it is unlikely to stay at this level, so it should be tracked as the large-cap proxy for MLCC recovery.
Lim Learning Department Manager, Chesley 14:42
TSE breakout validity still unclear
TSE pulled back below the breakout level after hitting a 52-week and all-time high, but volume on the decline was not heavy. The breakout is ambiguous, so it remains a watch to see whether it defends the breakout zone or rolls over.
Lim Learning Department Manager, Chesley 16:27
Hanwha Engine box breakout watch
Hanwha Engine rose 4% and has been trading in a two-month box. If it breaks out above that box, a more sustained trend advance could follow.
Lim Learning Department Manager, Chesley 16:49
KEPCO E&C leads nuclear names
KEPCO E&C rose 4.8% and has been the leader among nuclear stocks since August 25. It pulled back from 120-day resistance without volume, then resumed rising with higher volume in an N-shaped pattern; if trading nuclear, the speaker says to focus on KEPCO E&C as the leader.
Lim Learning Department Manager, Chesley 17:36
Doosan Enerbility lags nuclear leader
Doosan Enerbility is the weaker nuclear comparison: it rose about 60% from its low versus KEPCO E&C's 97%, and its rebound is less powerful. The speaker prefers the leading nuclear name over Doosan Enerbility.
Lim Learning Department Manager, Chesley 18:12
Samsung SDI holds 20-day support
Samsung SDI fell 2.8% after being picked as a weekly rising stock, but it is finding support at its 20-day moving average and is still moving inside a mini-box. The stock is a consolidation watch rather than a clean trend trade.
Lim Learning Department Manager, Chesley 19:03
L&F tries to resume uptrend
L&F, a cathode-material leader, rose about 100% in August and about 140% from its low to high, and is now consolidating while trying to turn back up. The stock is a high-momentum battery-material name to watch for a renewed upward turn.
Lim Learning Department Manager, Chesley 19:22
Korea Cosmetics Manufacturing leads cosmetics
Korea Cosmetics Manufacturing rose 19%, reached +28% intraday, and saw volume surge, making it the strongest cosmetics stock of the day. Its market cap of about 350 billion won means it moves more lightly, supporting its high-beta momentum.
Lim Learning Department Manager, Chesley 20:07
DB HiTek holds 5-day after pullback
DB HiTek fell 8% but held its 5-day moving average and remains above the mini-box it broke out of on September 8. The uptrend is still intact, so it should be tracked for continuation.
