A Narrow Rally,
Afternoon Breakdown

KOSPI -0.58% · after reaching 7,171.52 intraday, it closed near the day's low · 217 points surrendered from the high
Oil, trade, inflation and the yen all weighed on risk appetite in the afternoon, but the market's underlying support had been narrow since the morning
By 09:45, decliners already outnumbered advancers; by the close, only one in four stocks was higher

External catalysts reversed the direction, but the market had been vulnerable to a breakdown since the morning
MARKET PATH / 01

An Index Above 7,100, With Narrow Breadth From the Start

When did the direction change, and what was driving it?

THE READ

The morning advance was driven by the largest-cap names · even while the index was up more than 2%, decliners still outnumbered advancersKOSDAQ turning lower soon after the open sent the same signal · the index and the market beneath it were diverging from the startThe afternoon news flow was the trigger that reversed direction, not the sole cause of the day's character · because breadth was narrow, the pullback spread immediately across the marketEven then, the KOSPI 200 closed down less than the KOSPI · the two names at the very top of the market kept supporting the index into the close

OPEN · MORNING

Above 7,000 at the Open, but Breadth Was Narrow From the Start

Memory optimism after OpenAI Astra extended into strength in European semiconductors, +0.72% at the openAt 09:45: 7,070.16 · 336 KOSPI advancers versus 507 declinersKOSDAQ rose as high as 830.05, then had reversed lower to 821.69 by the same time

AFTERNOON

Direction Changed Above 7,100

The index reached the day's high of 7,171.52 around 13:00 · the upper candle on the 15-minute chart was the 13:00 bar13:27 7,162.06 · 13:50 7,139.83 · 14:00 7,071.09, a 100-point reversal in one hourOil, trade, inflation and yen-related concerns converged during this stretch

CLOSE

Closed 217 Points Below the High

The close was just 2.74 points above the intraday low · the reversal lasted through the bell 1,100.08(-0.46%) · 0.12 percentage point less than the KOSPI KOSPI 25.4% · KOSDAQ 29.4%, both below one-third of their respective markets

This is not a raw 15-minute chart. The line connects the four confirmed points—open, high, low and close—with reported intraday index levels. The dashed line marks the previous close at 6,995.39. The low occurred just before the close and overlaps the closing point, so it is not plotted separately.
WHY / 02

What Pressured the Afternoon—and What Drove the Morning

Only the catalysts that actually explain the day's direction
01

The main driver of the afternoon reversal was crude oil, which jumped on fears of Middle East supply disruption

Oil rose to a six-week high as the previous session's attack on Saudi Aramco's Jizan refinery coincided with an escalation in U.S.-Iran military clashesThe rise in oil was read as a renewed inflation risk and overwhelmed the morning's bullish narrative · rate-sensitive areas such as growth, biotech and gaming moved to the top of the declinersAt 13:19, foreign media reported that the Houthis had attacked cities in southern Saudi Arabia and Aramco facilities with missiles and drones, injuring 73 people · the timing overlapped with the index beginning to retreat from its high

+2.83%WTI $94.07 · during Korean trading hours
View evidence
Aramco's Jizan refinery was hit locally on September 7 · capacity of 400,000 barrels per day · the attacker had not been identified at that point
On September 5 local time, U.S. Central Command attacked three Iranian vessels · the U.S. described it as a response to Iran's ballistic-missile attack on U.S. Navy ships
Brent traded in the $97 range · highest since July 23 · WTI also at its highest level since late July
Houthi attacks on Saudi Arabia · from the night of September 7 into September 8 local time, missiles and drones targeted Abha, Khamis Mushait, Jizan and Najran · foreign-media reports at 13:19 KST confirmed the attacks and 73 injuries during the Korean session
A fire at energy facilities and partial operational shutdowns were reported later at 17:24 KST · because that information came after the Korean close, it was not reflected in today's pricing
The U.S. 10-year Treasury yield reached a 34-month high of 4.82% on September 3 before easing to the 4.78% area · September 4 close 4.784% · U.S. markets were closed on September 7, so there was no fresh confirmed close to compare during Korean trading hours
02

Trade, Inflation and Yen Concerns Added to the Oil Shock

Canada's retaliatory tariffs on U.S. goods took effect today · the measures had been announced on August 25, so this was not new information, but together with oil they brought trade uncertainty back into focusUSD/JPY fell to 152.89, the yen's strongest level in seven months · concerns over weighed on risk assets broadlyInflation caution ahead of U.S. producer prices on September 10 and consumer prices on September 11 pointed in the same direction

152.89USD/JPY · first move into the 152 handle since February
View evidence
Canada's retaliatory tariffs · about US$20bn (C$27.6bn) · roughly 700 product categories · 50% on steel, aluminum, furniture and apparel · 25% on appliances, dairy and seafood · 15% on industrial tools
Announced by the Canadian government on August 25 · effective September 8 · a response to the U.S. imposing 50% tariffs from August 22 on roughly US$20bn of Canadian goods
About 68% of Canada's total exports go to the U.S. · roughly 80% of those enter tariff-free under the trade agreement, but the latest U.S. measure relies on legal authority outside the agreement's exemption framework
Yen · after the joint U.S.-Japan intervention in July, USD/JPY had rebounded to 160 by late August before reversing in September · reports attributed the acceleration in yen strength to large stop-loss buying
USD/KRW 1,345.6 · up 5.1 won · daytime-session close · first rise in five sessions
03

The Morning Rally Came From Astra's European Follow-Through and a U.S.-Investment Nuclear Report

The previous session's strength in U.S. semiconductors had already been reflected in Korea on September 7 · what drove this morning was the extension of that momentum into European semiconductor stocksA report said the U.S. had proposed allocating US$120bn of the US$200bn investment package for the U.S. to the construction of as many as eight large nuclear reactors, lifting electricity & gas and construction names · negotiations are still under way, and the project mix and timeline remain unconfirmed

Retail Sold KRW 3tn, Concentrated in Samsung Electronics and SK hynix

Who moved the index today
INDIVIDUAL · KOSPI CASH
-KRW 3.033tn

Selling was concentrated in the two stocks that had surged the previous session · combined selling in the two names totaled KRW 3.4481tnThat was more than twice the KRW 1.275tn combined net buying by foreigners and institutionsBoth stocks also face a known September 10 KRX Semiconductor Index overhang · these are not shares that traded today

Samsung Electronics-KRW 2.1126tn
SK hynix-KRW 1.3355tn
Rebalancing overhang · futures · program trading · detailed flows
The KRX Semiconductor Index caps any single stock at 20% · as of September 4, SK hynix was 36.75% and Samsung Electronics 22.78%, both above the cap
Broker estimates of required selling: SK hynix KRW 1.244tn · Samsung Electronics KRW 206.8bn · estimated buying: Hanmi Semiconductor KRW 306.4bn · Jusung Engineering KRW 179.5bn · actual rebalancing trades are expected near the September 10 close
Jusung Engineering ranked fourth in foreign net buying today at +KRW 63.6bn and Hanmi Semiconductor fifth at +KRW 53.7bn, suggesting early positioning toward the names due for higher weights
Foreign +KRW 365bn
Institutional KOSPI 200 futures-KRW 1.277tn
KOSPI program trading+KRW 78.9bn
+KRW 123.3bn
Program trading split between arbitrage -KRW 44.4bnand non-arbitrage +KRW 123.3bn · a sharp reduction from +KRW 1.8565tn in the previous session
The cash KOSPI 200 closed at 1,100.08 at 15:30 while the futures contract ended at 1,098.40 at 15:45, a 1.68-point gap · because the closing times differ, this is not used as directional evidence
Samsung Electro-Mechanics was the top foreign net sell at -KRW 307.1bn, 23.8% of the KRW 1.289tn total value of foreign net-sell positions · it was also the largest institutional net sell at -KRW 124.4bn · both groups sold the same stock while retail absorbed the supply
Retail net buying: Samsung Electro-Mechanics +KRW 435.4bn · LG Innotek +KRW 88.9bn · Hyundai Motor +KRW 82.9bn · LG Energy Solution +KRW 67.3bn
buy/sell uses as its denominator the sum of the values of all stocks in which that investor group was a net buyer (or net seller), not the market-wide net balance · total foreign net-buy positions KRW 1.9973tn · total institutional net-buy positions KRW 1.583tn
KOSDAQ retail +KRW 149bn · foreign +KRW 62bn · institutional -KRW 218bn · the signs were opposite to KOSPI
KOSPI turnover was KRW 25.959tn, 137.5% of the five-day average · previous session KRW 21.762tn · KOSDAQ KRW 8.002tn, 143.2%
Short selling: KOSPI KRW 1.2751tn · 3.49% of applicable turnover (3.10% previous session) · KOSDAQ KRW 338.4bn, 3.62% · the short-sale data cover the combined KRX and NXT regular markets, so the denominator differs from the KOSPI turnover figure above

Today's distribution of strength and weakness, not just a ranking table

Strength survived only in nuclear/power and construction; almost everything else moved lower together.Those two pockets were driven by the U.S.-investment nuclear report, while the rest of the market was pushed in the same direction by the afternoon catalystsThe weakest areas were rate- and cost-sensitive growth, biotech and gamingElectrical & Electronics fell -0.41%, less than the KOSPI manufacturing average · semiconductors were the area still supporting the index

Answers to Yesterday's Questions

Checking today's result against the previous session's conditions
YESTERDAY → TODAY

Yesterday's first question was whether KOSPI could close above 7,000 · today's answer: no · the index traded above 7,000 from the open and reached 7,171.52 intraday, but closed at 6,954.52The second question—whether foreigners and institutions would continue to buy together—was still positive in sign, but the amount fell to roughly one-quarter of the previous sessionThe third question—whether the rally would broaden—went the other way · the share of advancers fell from about half the market to one in four, confirming the concern left open yesterdayIn the 11 sessions since August 24, KOSPI has closed above 7,000 zero times · on August 27 it stalled at an intraday high of 6,996.12 · today it traded more than 171 points above 7,000 intraday but still finished back below it

What to Check Next Session

Conditions that can actually be scored, rather than probabilities
Does the 25.4% share of advancers recover?

The root of today's decline was narrow breadth from the morning · even if the index rebounds, a reading below 30% would mean a few top-cap names are still carrying the index · check it alongside KOSDAQ's 29.4%

Does crude oil keep weighing on the index next session?

Watch whether WTI moves higher from $94.07 and Brent from the $97 area · after U.S. markets reopen tonight, score it using the direction of oil and the U.S. 10-year yield, then the signs on Korean chemicals, transportation and airline stocks next session

How do flows in the two mega-cap chip names behave around the September 10 semiconductor-index rebalancing?

Estimated selling in Samsung Electronics and SK hynix totals roughly KRW 1.45tn · because rebalancing falls on the same day as derivatives expiry, watch it together with program flows · also check the signs on Hanmi Semiconductor and Jusung Engineering, whose index weights are expected to increase

Between an intraday break and a closing hold, KRW 3tn in retail selling showed how formidable the 7,000 line still is.
