01WHAT THE WEEK LEFT BEHIND

Three days pressed by yields and selling ·
two days back on different catalysts

Only what this week left in price · flows · breadth · For the day-by-day path, see each Daily

Weekly performance · 2026.09.28~10.02Top 10 stocks by market cap plus benchmark indices · versus Sep. 23 close

Stocks use regular-session closes on Sep. 23 and Oct. 2 · Samsung Electronics and Samsung Electronics Pref. include the Sep. 29 ex-dividend move · stock returns and index returns use different calculation methods, so they are not ranked together

01

Foreigners sold all five days ·
Other corporations took the other side

  • Foreign KOSPI cash selling was largest on Sep. 28 at -KRW 3.226tn· the daily amount then shrank each session, reaching -KRW 144bn
  • on Oct. 2 · five-day totals: foreign -KRW 8.873tn · institutions -KRW 948bn · individuals +KRW 1.763tn · subtracting their combined -KRW 8.058tn from zero implies about +KRW 8.058tn for other corporations
  • Foreigners were net sellers of KOSPI 200 futures by KRW 778bn over five days, but on Oct. 2 alone they bought +KRW 859bn · futures turned before cash equities did
02

A broad advance,
a heavy-index Monday

  • On Sep. 28, KOSPI was -2.70%while the share of advancing stocks was 66.9% · Samsung Electronics -5.43% · SK hynix -5.05% · SK Square -7.56%
  • Sep. 28 showed the index and market breadth moving in opposite directions · on the 29th, KOSPI fell 0.27% and the share of advancing stocks was 25.4%· both index and breadth weakened together · Samsung Electronics rose 0.93% that day versus its ex-dividend reference price
03

The below-half streak
ended on Monday

  • Share of advancing stocksis the number of KOSPI gainers divided by all KOSPI-listed stocks that day · the dashed line marks 50%
  • All eight sessions covered by the previous Weekly, Sep. 14–23, were below half · this week, three of five sessions were above half
04

Even on all three KOSPI down days ·
KOSDAQ rose

  • Weekly KOSDAQ +5.78% · KOSPI -1.09% · gap 6.87%p · on Sep. 28–30, when KOSPI fell, KOSDAQ gained +0.25% · +0.38% · +0.72%
  • Foreign selling was concentrated in KOSPI cash equities · five-day foreign flow: KOSDAQ -KRW 95bn · KOSPI -KRW 8.873tn · KOSDAQ institutions +KRW 642bn, including KRW 568bn on Oct. 1 alone
  • Sep. 28 · Biotech · HLB limit-up (+29.95%) · after U.S. FDA approval of its cholangiocarcinoma treatment on Sep. 23 local time · KOSDAQ Pharmaceuticals +2.76%

LAST WEEK'S QUESTION · Did the reopening session hold its opening level?
NOT MET.
  • Sep. 28 open 7,057.86 · close 6,889.74 · versus the open -168.12p
  • the gap was only -23.06 points; most of the decline came after trading began
LAST WEEK'S QUESTION · Did the share of advancing stocks recover above 40%?
MET.
  • Above 40% on three days · Sep. 28 · Oct. 1 · Oct. 2 · all three also exceeded 50%
  • But on Sep. 28, the index itself fell 2.70%
LAST WEEK'S QUESTION · Did the U.S. 10-year return below 5%?
NOT MET.
  • U.S. Treasury daily par yields · Sep. 28 5.24% · 29th 5.26% · 30th 5.29% · Oct. 1 5.24% · 2nd 5.28% · zero days below 5%
  • Even after August PCE inflation came in below expectations (core 3.0% · consensus 3.3%), the 10-year did not come down
02THREE VARIABLES FOR NEXT WEEK

Three trading days,
the numbers packed into them

Korean trading days: three sessions, Oct. 6–8 · market closed Oct. 9 for Hangul Day · on the 8th: Fed minutes · China reopening · Samsung Electronics preliminary earnings · Q1 and Q2 are scored across all three sessions · Q3 on Samsung Electronics preliminary earnings alone

Q.01

Will KOSPI finish
above 7,000 on all three days?

  • Oct. 2 close: 7,003.74 · distance from 7,000: 3.74p · KOSPI was below 7,000 near the end of continuous trading at 15:20, then moved back above it in the closing auction
  • The Oct. 6 open will absorb U.S. September payrolls · the U.S. September ISM Services Index on Oct. 5 local time · and two U.S. sessions at once · with the market sensitive to long-term yields above 5%, the ISM price and employment components are the first numbers to watch
  • The Oct. 8 Korean open comes after the Fed's September meeting minutes at 03:00 · despite weak payrolls, the U.S. Treasury 10-year par yield has risen from 5.24% to 5.28% · the minutes are therefore a discount-rate variable on par with earnings, in our reading · mainland China also reopens at 10:30 that day for the first time since Sep. 30
  • NH Investment & Securities puts next week's KOSPI range at 6,500~7,500· and cites a potential Samsung Electronics earnings shock and a renewed rise in U.S. hike odds as downside risks, according to media reports

SCORECARD · Met if KOSPI closes above 7,000 on all three sessions from Oct. 6–8 ·
Partly met if one or two sessions · not met if zero

SIGNS IT HOLDSForeign net buying in cash equities · advancing stocks above 50% · Samsung Electronics and SK hynix both higher
CONDITIONS FOR A BREAK BELOWSamsung Electronics preliminary earnings fall into Q3's “not met” zone · U.S. Treasury 10-year par yield at or above 5.30% (top of Hanwha Investment & Securities' October range)
SEPARATE VARIABLE TO WATCHThree trading days followed by another three-day holiday · the Oct. 8 close is the price investors carry across the Hangul Day break
Q.02

Will foreigners in KOSPI cash equities
turn net buyers?

  • Since Sep. 23: six straight sessions of net selling · but this week's daily selling amount fell every day
  • On Oct. 2, foreign flow in KOSPI 200 futures was +KRW 859bn net buying · futures turned before cash equities did
  • On Oct. 2, the No. 1 and No. 2 stocks by foreign net selling were SK hynix and Samsung Electronics · No. 1 net buy was Samsung Electro-Mechanics · No. 2 was SK Innovation (rankings only)
  • Hanwha Investment & Securities calculates that the gap between foreign-owned Korean market cap and ACWI has widened to +107.7pp · historically, it says foreign investors ultimately reduced exposure toward global-index weights · Yuanta Securities notes that foreign buying tends to dominate when USD/KRW is below its six-month moving average · this week USD/KRW moved from KRW 1,358.4 to KRW 1,350.6 per dollar, based on 15:30 weekly closes

SCORECARD · Met if foreigners (including other foreign investors) are net buyers of KOSPI cash equities on
at least two of Oct. 6–8 · partly met if one day · not met if zero · based on the KRX 15:38 tally

SIGNS OF A TURNFutures net buying continues · USD/KRW below 1,350 · semiconductors move into the top net-buy list
CONDITIONS FOR CONTINUED SELLINGSamsung Electronics misses earnings expectations · U.S. yields rise again · SK hynix and Samsung Electronics remain No. 1 and No. 2 in foreign net selling
HOW TO READ THE NUMBERScore cash equities and futures separately · also check over the same three sessions whether buying by other corporations fades
Q.03

Will Samsung Electronics Q3 operating profit
exceed KRW 110tn?

  • Operating-profit consensus has fallen from KRW 113.1tn in early September to KRW 109.5tn· a downgrade reflecting won strength, according to media reports · Q4 consensus is KRW 120.8tn
  • Daishin Securities uses above KRW 110tnas the line to watch · broker estimates range widely, from KRW 104tn at DS Investment & Securities to KRW 118.8tn at Hana Securities
  • DS Investment & Securities cites USD/KRW falling about 11% from the end of Q2 (FX assumption: KRW 1,430 → KRW 1,370 per dollar), mobile input costs, and appliance expenses as reasons for a miss
  • The same day is also Daishin Securities' estimated end date for Samsung Electronics' buyback · earnings and flows converge on one session

SCORECARD · Met if preliminary operating profit is at least KRW 110tn · partly met if at least KRW 104tn but below KRW 110tn ·
Not met below KRW 104tn · KRW 110tn is the consensus/Daishin threshold · KRW 104tn is the DS Investment & Securities estimate · if the release date changes, score the number on the actual release date

SIGNS OF AN UPSIDE BEATMemory-price gains outweigh the FX drag · Q4 expectations remain around KRW 120tn
CONDITIONS FOR A MISSWon strength has a larger-than-expected impact · pressure from mobile and appliance costs
HOW TO READ THE NUMBERPreliminary earnings include only revenue and operating profit · segment figures come with final results at end-October · stock-price reaction will be recorded separately from the score
03SECTOR PRIORITY

Only No. 1 semiconductors gets the full catalyst path · the other three are reduced to why now · what to watch · risk in three lines

Semiconductors · Memory

WHAT TO WATCH FIRST IN THIS SECTOR

The first checkpoint is Samsung Electronics Q3 preliminary earnings
A number lands on the two stocks topping foreign net selling

Expected around Oct. 8, based on media reports · this week Samsung Electronics -3.33% · SK hynix -1.13% · Samsung Electronics Pref. -8.64% including the ex-dividend move · both fell on the week even with Micron's results and record September semiconductor exports of $60.3bn · on Oct. 2, they were again No. 1 and No. 2 in foreign net selling
Why it matters WHY NOW
  • SK hynix Q3 operating-profit consensus is KRW 77.55–78.13tn (Hanwha/Daishin compilations) · Samsung Electronics consensus · estimate range · threshold are 02 Q3
  • The flow calendar overlaps too · Daishin Securities estimates Samsung Electronics' buyback will end around Oct. 8 · and SK hynix around Oct. 16 (58.8% of the plan completed)
  • The industry evidence is already visible · Micron says demand will exceed supply through 2028 and that more than 75% of its 2027 output is already committed to customers · IBK Securities points to strategic customer agreements (SCAs) rising from 16 in the prior quarter to 26
KRW 109.5tnSamsung Electronics Q3 operating-profit consensus · based on media reports

Exports hit a record ·
but earnings estimates moved the other way.

BROKER VIEWS WHAT THE STREET SAYS
  • Daishin Securities sees Q3 earnings as key to breaking KOSPI out of a 6,500–7,200 range · its bullish threshold is above KRW 110tn for Samsung Electronics and KRW 80tn for SK hynix
  • DS Investment & Securities sets a KRW 530,000 target for Samsung Electronics · and cuts its SK hynix target from KRW 3,100,000 to KRW 2,640,000
  • Hana Securities estimates KRW 118.8tn for Q3 and KRW 126.6tn for Q4, with a KRW 480,000 target price
  • NH Investment & Securities says the semiconductor earnings uptrend remains intact despite near-term profit concerns from won strength and lists the sector as a core holding, according to media reports
WHERE VIEWS DIVERGE

The numbers diverge even within the same week's research · a chart in Hanwha Investment & Securities' September export report shows month-on-month export prices per kilogram down 3.5% for commodity DRAM and 22.0% for NAND, while the text describes DRAM pricing as “unchanged” · Eugene Investment & Securities calculates that semiconductors accounted for about 79% of September's export increase, showing greater concentration · Daishin Securities says peak-cycle concerns are premature · the real disagreement is not whether prices are rising, but how much of that rise survives into earnings estimates

NEXT CATALYSTS AND FAILURE CONDITIONS NEXT CATALYST
  • Oct. 6 Reopening · absorbs U.S. September payrolls · ISM Services and two U.S. sessions · Nvidia hit an intraday record high on Oct. 2 local time
  • Oct. 8 · 03:00 Fed September meeting minutes · Samsung Electronics preliminary earnings expected the same day, based on media reports · for the schedule, see 05 · DATES
  • Oct. 14 · 21:30 U.S. September CPI · final inflation print before the Oct. 27–28 Fed meeting · Daishin Securities sees whether core month-on-month inflation exceeds 0.3% as key to the October hike decision
  • FAILURE CONDITIONS · preliminary operating profit falls into Q3's “not met” zone · Samsung Electronics and SK hynix both underperform KOSPI that day · the two remain No. 1 and No. 2 in foreign net selling

Outside semiconductors ·
each catalyst has a different confirmation date.

DATE-BOUND

Refining

WHY NOW

Oct. 2 · S-Oil +11.69% · SK Innovation +10.32% · Reuters reported that Chinese refiners halted refined-product exports outside Hong Kong and Macau until further notice · Asian gasoline cracks versus Brent reached a record $50.53 per barrel

WHAT TO WATCH

China's National Day holiday ends Oct. 7 · reports say any restart depends on inventories and refinery runs · China's commodity futures markets also trade again on the 8th for the first time since Sep. 30 · the Oct. 4 local OPEC+ meeting is expected to keep November production targets unchanged (Reuters · ahead of the decision) · according to Yuanta Securities, Q3 operating-profit consensus over one month: S-Oil KRW 1.0935tn → KRW 1.5686tn · SK Innovation KRW 1.6387tn → KRW 2.8123tn · Hana Securities target prices: S-Oil KRW 220,000 · SK Innovation KRW 200,000

RISK

Kiwoom Securities cites procedures for up to 40 million barrels of additional U.S. Strategic Petroleum Reserve supply · resumed Saudi exports · and October U.S. refinery maintenance as reasons crude oil has largely found a near-term peakin its view · even within petrochemicals, estimates diverge · one-week Q3 earnings revisions: refining +10.0% · chemicals -17.4% (Yuanta) · chemicals remain unable to pass through higher input costs (Eugene)

COUNT THE STAGES

Defense

WHY NOW

Oct. 2 · K-AI Defense TOP5+ +4.66% · LIG Defense & Aerospace +5.25% · Hanwha Systems +5.07% · closing reports cited a combination of heightened Middle East military tensions and news on selection of developers for the KF-21 guided-weapons system

WHAT TO WATCH

Kiwoom Securities says the sector's 12-month forward P/E has fallen from 34x to 21x, near what it sees as a bottom, but makes year-end air-defense ordersa prerequisite for recovery · Q4 expectations include a contract for 16 Indonesian KF-21s (more than KRW 4tn) · Kiwoom target prices: LIG Defense & Aerospace KRW 1,350,000 · Hanwha Aerospace KRW 1,580,000

RISK

Saudi and Iraqi orders could slip from year-end into early next year (Kiwoom) · one day's Middle East news should not be conflated with the order process · count framework agreements separately from final contracts, and deliveries separately from orders

NEEDS CONFIRMATION

Secondary batteries

WHY NOW

LG Energy Solution's weekly return was +5.55%No. 1 among the top 10 stocks by market cap · K-AI Secondary Battery +3.38% on Oct. 2 · Tesla delivered 486,532 vehicles in Q3 on Oct. 2 local time, above Bloomberg's 463,000 consensus, according to reports

WHAT TO WATCH

Hana Securities sees the absence of batteries as a direct agenda item at this U.S.-China summit as a near-term easing of policy risk · it sees ESS orders concentrated in Q4 · Hanwha Investment & Securities expects lithium to remain in supply deficit for three straight years from 2026 to 2028

RISK

Earnings revisions are moving in opposite directions · LG Energy Solution's full-year EPS estimate is down 35.9% in one month · Samsung SDI Q3 operating-profit consensus is up 39.2% in one month (Hanwha compilation) · do not treat Tesla deliveries and Korean cell makers' earnings as the same signal

04WHAT CROSSES THE HOLIDAY

While Korea is closed,
the numbers arriving first

Weak U.S. payrolls · U.S. long-term yields that still did not fall · Chinese refined products waiting on the end of the holiday · and the remaining window for those absorbing foreign selling

10.02 · U.S. PAYROLLS

Payrolls were weak · the 10-year still did not come down

  • U.S. September nonfarm payrolls +29,000 · consensus +84,000 to +90,000 depending on source · unemployment rose to 4.2% · July and August revised down by a combined 60,000 · average hourly earnings +3.0% YoY
  • On Polymarket, the probability of an October hike fell from about 69% on Sep. 28 to 16%· Treasury yields fell immediately after the release, then rebounded · the Treasury 10-year par yield moved from 5.24% to 5.28%· and the 2-year from 4.78% to 4.83%
  • Stocks rose after the weak jobs report · Dow +0.49% · S&P500 +0.73% · Nasdaq +1.19%
  • In a pre-release note, Kiwoom Securities argued that even softer employment would not quickly pull the 10-year lower · Hanwha Investment & Securities sets an October 10-year range of 5.08–5.30%
10.01–08 · CHINA

Refined-product export halt · the first test comes in the two days after the holiday

  • Chinese refiners halted exports of gasoline · diesel · jet fuel outside Hong Kong and Macau until further notice (Reuters) · PetroChina canceled several October cargoes
  • After the National Day holiday ends on Oct. 7 reports say any restart depends on inventories and refinery runs · that date will tell whether the catalyst for Korean refiners lasts beyond one day
  • On Oct. 8, mainland Chinese equities and commodity futures reopen for the first time since Sep. 30 · they will absorb accumulated moves in oil · U.S. payrolls · and U.S. equities at once · 10:00 KST commodity futures · 10:30 KST equities
  • Oil · Dec. Brent at $102.31 on Oct. 1 local time (+4.37%)
09.28–10.08 · FLOWS

The side absorbing foreign selling · the remaining window

  • This week's implied other-corporation buying was about +KRW 8.058tn · not a directly reported figure, but zero minus the sum of foreign · institutional · and individual flows
  • Samsung Electronics' buyback was also under way over the same period · scheduled Aug. 24–Nov. 21 · planned amount about KRW 15tn · progress differs by source (Daishin compilation: KRW 10.31tn cumulative · 74.7% of plan · media reports: about 90% by end-September)
  • Daishin Securities estimates completion around Oct. 8 for Samsung Electronics and around Oct. 16 for SK hynix · there is no stock-by-stock dataset that directly links the other-corporation category with company buybacks
  • Views differ · iM Securities says large-cap flows could weaken once buybacks end · Daishin Securities says foreign investors and financial-investment firms could fill the gap if rates and FX stabilize
05DATES TO CHECK
