Summary

The video is an August 31 midday market interview with Lee Ju-hyun, CEO of Blue Dream Research. He explains that KOSPI recovered from early weakness driven by hawkish Fed interpretation and China memory news, helped by Samsung Electronics and SK Hynix buybacks. He highlights secondary battery materials, SK IE Technology, beauty/cosmetics and bank stocks, while noting Cosmecca Korea has reached fair value.

  • KOSPI started weak on hawkish Fed interpretation and China LPDDR6 memory news before recovering.
  • Samsung Electronics and SK Hynix buybacks supported downside; Samsung's medium/long-term uptrend is intact.
  • SK Hynix's target-price cut still implies meaningful upside, and its HBM competition concern is seen as stale.
  • Secondary battery materials led by L&F and POSCO Future M on lithium and ESS demand.
  • Beauty sector remains at new highs, with September 1 export data as the next key check.
  • Big four Korean bank holding companies are favored on rate spreads, dividends and defensive flows.
  • Foreigners net bought about 3 trillion won of KOSPI futures in August, with positions likely held into September expiry.
Ideas
Lee Ju-hyeon Director, Xangle 5:02
Buyback supports downside; medium-term uptrend likely.
Samsung Electronics is being supported at the downside by its buyback/shareholder-return policy and by investor confidence; the stock defended its prior low and reversed intraday from a sharp drop. Near-term price action is still forming lower highs and may see more short-term adjustment, but from a medium/long-term perspective the uptrend is likely to continue.

Target cut still leaves meaningful upside.
SK Hynix was pressured after LS Securities cut its target price from 330,000 won to 240,000 won while keeping a buy rating, but with the stock near 160,000 won the target still implies meaningful upside. The report's HBM competition concern is seen as stale because Samsung and Micron have been competing in HBM for some time, so the target-cut logic is questionable.

Lithium and ESS demand boost battery materials.
The secondary battery sector is relatively strong in a weak tape, with L&F and POSCO Future M leading within the group. The move is driven by rising lithium carbonate prices and increasing ESS demand tied to the energy mix, giving the sector momentum.

Lee Ju-hyeon Director, Xangle 11:30
Merger plunge reversed; valuation still cheap.
SK IE Technology fell sharply on merger-related news from its prior low but reversed strongly today. The stock was already cheap on valuation following the merger, and the additional event-driven drop made it cheaper; today it is rebounding aggressively and standing out among secondary battery names.
361610.KS MED
Lee Ju-hyeon Director, Xangle 14:01
Fair value reached; upside attractiveness wanes.
Cosmecca Korea rose about 10% this morning and reached roughly 10 times earnings based on projected 2028 earnings of about 160 billion won, implying a market cap around 1.6 trillion won. The stock is not expensive but no longer cheap; fair value has been reached and upside attractiveness has dropped sharply. Heavy volume here could be a late-stage signal.
241710.KQ MED
Lee Ju-hyeon Director, Xangle 15:23
Beauty sector hits highs; watch export data.
The Korean cosmetics/beauty sector is making new highs and remains one of the most visible sectors. The next key test is the September 1 export data, which should be watched to see whether the sector's momentum carries into September.
KORU MED
Lee Ju-hyeon Director, Xangle 15:40
Rate spreads and dividends favor big banks.
Korea's big four bank holding companies are making new highs. Bond yields rose after two consecutive rate hikes, widening interest spreads and supporting bank margins; banks also have shareholder return policies and dividends, and defensive flows into banks when the market is weak should support a slow, steady advance.

Foreign futures buying likely persists until expiry.
Foreigners have been net buying KOSPI futures since early August, accumulating about 3 trillion won by month end. This futures position is likely to be maintained at least until the September futures/options expiry. Today's intraday volatility is mostly weekly option trading, so the underlying futures position remains supportive and limits downside.
