📈 KOSPI Surges 2.6% as Semiconductors and Banks Lead Broad-Based Rally With Samsung and SK Hynix Flagged as Undervalued

South Korean equities posted their strongest session in weeks, with the iShares MSCI Korea ETF +2.55% reflecting a broad advance led by Tech/Semiconductors +2.76% and Banks +1.64%. The session delivered across all three major tracked sectors — Tech/Semi, Banks, and Industrials +1.47% — making today's move a conviction broad rally rather than a narrow sector rotation. LPL (LG Display) led gainers at +2.76%, while the banking complex showed unusual strength with SHG (Shinhan Financial Group) +1.71%, KB Financial +1.65%, Woori +1.56%, and KEP (KEPCO) +1.47% all posting solid gains. Korea's semiconductor story is the most closely-watched theme globally: the consensus view among Korean market analysts today, per 뉴시스 financial reporting, is that both Samsung Electronics and SK Hynix are still in undervalued territory despite recent gains — the HBM (High Bandwidth Memory) cycle thesis remains intact heading into Q4. Korean Bitcoin and crypto investors are also in focus: with a cryptocurrency capital gains tax deadline three months away, 82.9% of Korean investors surveyed say the tax needs either a delay or major revision — a policy watch item that could affect the retail-driven KOSDAQ volatility profile.

Samsung and SK Hynix Flagged as Still Undervalued — HBM Cycle Thesis Intact

Korea's 뉴시스 financial desk reports that leading local analysts are calling Samsung Electronics and SK Hynix 'in undervalued territory' despite recent KOSPI gains, with the HBM cycle thesis underpinning the bullish case for both semiconductor names. SK Hynix, the dominant supplier of HBM3E memory to Nvidia's H100 and H200 AI accelerators, has been the stronger performer of the two but still trades at a discount to its through-cycle DRAM revenue potential. Daniel Park's read: the key to breaking out of the current KOSPI trading range for semis is the next Samsung earnings cycle — order books for 2027 HBM supply agreements with US hyperscalers are the data point that could trigger a re-rating that current prices don't reflect.

Korea Faces 241 Trade Restriction Cases on Exports as Protectionism Rises Globally

동아일보 reports that Korean exporters now face 241 separate trade restriction or anti-dumping investigation cases globally, up 11 in the last six months — reflecting accelerating protectionist pressures on Korea's steel, battery, semiconductor, and EV component export sectors. The most exposed Korean sectors are steel (POSCO, Hyundai Steel) and EV battery (LG Energy Solution, Samsung SDI, SK On), where trade remedies from the US and EU are increasingly targeting Korean manufacturers for alleged dumping and subsidy violations. This is a structural headwind for Korea's export-driven economy: the KOSPI's heavy weighting toward chaebol export names means trade restriction escalation is a direct multiple-compression risk for the index, even on days like today when the broader sentiment is positive.

82.9% of Korean Crypto Investors Want Delay or Revision to Tax Starting December

뉴시스 reports that a survey of Korean cryptocurrency investors found 82.9% believe the capital gains tax on crypto — set to take effect in three months — needs either a delay or substantive revision, continuing years of political tension between crypto-native retail investors and Korea's tax authorities. Korea has the highest retail cryptocurrency participation rate of any major economy, with crypto trading volumes on KRW exchanges frequently exceeding the KOSDAQ by daily notional value. The policy risk is real: a December 2026 implementation without revision could trigger a pre-tax-deadline sell-off in Korean crypto and a retail re-allocation into gold, KOSDAQ growth names, or offshore assets — a KOSDAQ volatility catalyst to track into Q4.

Tech/Semi+2.76%Banks+1.64%Industrials+1.47%

Smart-money note

Today's +2.55% KOSPI print was broad-based with the right sectoral composition: Tech/Semi +2.76% means institutional money is re-entering the Samsung/SK Hynix trade after a period of relative underperformance versus the Nikkei and Taiwan markets. Banking +1.64% is the second institutional signal — Korean banks (Shinhan, KB, Woori) outperform when global yield curves steepen and domestic credit quality holds, both of which are true today. The chaebol governance discount is an underappreciated tailwind: FSC guidance on governance reform for Korean conglomerates is nudging holdco structures toward more shareholder-friendly capital allocation, similar to what Japan's TSE reforms achieved — this is a multi-year structural multiple expansion driver for KOSPI large-caps. The 241 trade restriction cases on Korean exports is the most important structural risk I'm watching this quarter — if the EU follows the US in imposing battery tariffs on Korean EV suppliers, LG Energy Solution and Samsung SDI face a significant revenue reforecast cycle. Risk for tomorrow: KRW/USD — the Korean won is sensitive to global risk sentiment, and any geopolitical escalation over the weekend (Middle East, North Korea DMZ situation) would trigger a KRW weakness spike that reverses today's KOSPI gains at the Monday open.

What to watch tomorrow

Samsung Electronics order backlog

Any news on Samsung's HBM4 supply agreements with US hyperscalers for 2027 delivery — even informal reports — is the single highest-impact catalyst for the KOSPI's semiconductor sector, where current prices embed skepticism about Samsung's ability to close the HBM gap with SK Hynix.

Korean crypto tax policy signal

With the December crypto capital gains tax 3 months away, watch for any government statement on delay or revision — a delay announcement would trigger immediate retail KOSDAQ-buying euphoria, while a 'tax as scheduled' signal could start a pre-deadline crypto selloff in November.

Bank of Korea rate path commentary

BoK's next scheduled meeting is in October; any weekend commentary from Governor Rhee Chang-yong on inflation and rate trajectory matters for KRW direction and the banking sector's NIM expansion expectations — the Chuseok season's food price surge (+16-18% beef prices) adds a hawkish CPI complication to the BoK's easing calculus.
