Review Note

The direction was right, but the reason was different. All three internal-market signals cited for the upside persisted, yet the jobs report—excluded from the probability score—was what actually drove today's session. And the outcome of that report, which had been classified as a downside risk, worked in the opposite direction. The revised conditions introduced on Aug. 7 were applied for the first time today and worked as intended. Under the old conditions, the signal would have failed simply because both top market-cap stocks fell. But a decline of less than 0.5% cannot reasonably be called a sharp drop.

What Drove Today
TriggerOn the night of Aug. 7, U.S. July payrolls fell by 23,000. That overturned expectations for an 83,000 increase, but the retreat in rate-hike expectations was priced first: the Nasdaq rose +1.30% ⁠· SOXPhiladelphia Semiconductor Index (SOX), a key gauge of global semiconductor stocks +2.56%, while the S&P 500 finished at a record high
PathKOSDAQ triggered a buy-side sidecar at 09:50 and climbed throughout the day, while the KOSPI retreated from its 6,394.06 high under foreign selling before rebounding
ResultKOSPI +0.65% · KOSDAQ +6.97%. In the Semiconductors & Semiconductor Equipment sector, 159 of 171 stocks advanced, yet the sector index rose only +0.30%

Unemployment rate (%)4.24.1
Labor-force participation rate (%)N/A61.4

May and June payrolls were also revised down by a combined 103,000 downward revision⁠· The 4.1% unemployment rate came with a decline in labor-force participation to 61.4%, making it difficult to read as a straightforward improvement in labor conditions. U.S. equities nevertheless rose. The market first priced a reduced need for further rate hikes: the U.S. 10-year yield fell to 4.660%, and the Russell 2000 +1.10% outperformed the S&P 500 (+0.62%).

02
The Two Stocks That Held Back the Index—and the Rest That Rose

· The KOSPI's No. 1 and No. 2 names by market cap moved against the broader market: Samsung Electronics KRW230,000 (-0.43%) and SK Hynix KRW1,420,000 (-0.14%)· The next tier rose: Samsung Electronics preferred KRW172,000 (+1.12%), SK Square KRW949,000 (+1.06%), LG Energy Solution KRW367,500 (+2.08%), and HD Hyundai Heavy Industries KRW532,000 (+5.1%)· KOSDAQ leader Alteogen moved to the front at KRW348,000 (+14.1%)

The modest KOSPI gain despite very strong breadth was largely due to slight declines in its two heaviest stocks. For sector-level strength and weakness, see Sector Strength & Weakness below.
03
Who Bought and Sold

Foreign investors sold KOSPI for a third straight session, with net selling again exceeding KRW1tn. The selling was once more concentrated in three large IT names, led by Samsung Electronics. Retail and institutions absorbed the supply, while foreigners were net buyers on KOSDAQ.

For investor-level amounts and stock-level flows, see Flow Structure below.
What the Close Means

Index +0.65% alone does not capture the scale of today's move. Of 79 sectors, 57 finished higher; of 219 themes, 214 advanced.

Flow StructureKOSPI⁠· Naver Finance investor data
Retail+KRW900.3bn
Foreign−KRW1.4887tn
Institutions+KRW566.9bn

The bars above use Naver Finance investor data; the stock-level flows below use KRX stock-level investor data . Because the market scopes differ, the figures are not summed and no cross-market shares are calculated.

Foreign selling was again concentrated in three large IT names, led by Samsung Electronics. Samsung Electronics −KRW1.0164tn · SK Hynix −KRW410.3bn · Samsung Electro-Mechanics −KRW156.4bn. KRX all-stock market basis: Samsung Electronics accounted for 42% of net selling and the top five names for 69%. Concentration, which had eased to 23% and 37% yesterday, narrowed again. On the other side, retail bought Samsung Electronics for +KRW842.2bn, while institutions bought +KRW145.1bn . That helps explain why a stock sold by foreigners by more than KRW1tn fell only 0.43% at the close.

In absolute terms, KOSPI turnover at KRW18.84tn was far larger than KOSDAQ's KRW7.07tn. The divergence was relative to normal levels: KOSPI turnover was just 72% of its five-day average, the thinnest in this phase, while KOSDAQ reached 122%, above average. Relative to normal activity, trading momentum tilted sharply toward KOSDAQ.

Foreign investors returned to net buying after two sessions, this time buying large-cap semiconductors. Retail took profits

08.04Retail+KRW0.82tnForeign−KRW0.37tnInstitutions−KRW0.54tn

All three investor groups kept the same direction, but the amounts shrank sharply. The focus of selling shifted to institutional selling of Samsung Electronics

Five-session cumulative flow (Aug. 4–Aug. 10): Retail +KRW4.14tn / Foreign −KRW4.61tn / Institutions +KRW208.0bn. As the Aug. 3 figure of −KRW2.82tn dropped out of the five-session window, cumulative foreign selling declined, while institutions' two consecutive buying sessions turned their five-day cumulative flow positive.

Cash-Futures Closing Basis

Cash 977.84 · Futures 979.00. The cash market closes at 15:30, while KOSPI200 futures close at 15:45, so the two closing prices have different timestamps. The simultaneous 15:30 futures price was not verified and is therefore excluded from the upside/downside assessment.

The combination of foreign cash-equity selling and futures buying has persisted for three sessions. One day's data cannot determine whether the futures buying reflects a directional turn or the unwinding of earlier short positions. KOSDAQ program trading switched to +KRW190.1bn net buying, the exact opposite of KOSPI's −KRW1.3679tn net selling. Program trading is already included in investor-level flow data, so it is not added separately.

Nonferrous Metals recovered in two sessions from last place on Aug. 7 (-7.23%). Semiconductors & Semiconductor Equipment +0.30% ranked 53rd, but the picture inside the sector was completely different (Sector Read 01). ※Single-stock sectors and “Other” are excluded from ranking commentary.

Declines in the No. 1 and No. 2 stocks by market cap diluted much of the rise in the rest of the sector. The seven-stock S7 large-cap semiconductor theme +0.42% shows the contrast clearly. Short SellingSelling borrowed shares to profit from a decline in the share price accounted for KRW1.36tn on KOSPI, or 5.4% of combined KRX+NXT turnover, down from 6.2% the previous session.

The sector index and the picture inside the sector diverged. Nearly all semiconductor materials, parts and equipment names rose, while the index was held down by declines in the two largest market-cap stocks.

Only 21 of 79 sectors and 5 of 219 themes declined. The top two laggards fell for different reasons. Banks weakened alongside the retreat in rate-hike expectations, with 8 of 11 bank stocks declining. Telecom, by contrast, generally benefits from lower rates, so its weakness was closer to relative underperformance as capital rotated into growth stocks.

The 21 declining sectors cannot be tied to one macro cause. Banks were driven by rates; telecom by capital rotation.

What to Watch Next Session
Next-Session Probability⁠· Upside bias based on domestic closing signals
Upside 55%
Downside 45%

55:45 is not a quantified forecast probability. It represents the relative weight of upside and downside conditions confirmed as of the 15:30 market close.

Upside ① Advancers have led for six straight sessions, with breadth widening from 60.9% to 76.5%, the strongest in this phase ② U.S. July employment weakened, reducing rate-hike expectations ③ Institutions bought KOSPI for a second straight session and KOSDAQ by +KRW566.1bn. Downside ① Foreign cash-equity selling extended to a third session and widened to −KRW1.4887tn② KOSPI turnover was only 72% of its five-day average ③ Program selling continued for a third session and more than doubled from yesterday ④ U.S. July CPI remains ahead on the night of Aug. 12.

FlowsWhether foreign cash-equity selling extends to a fourth session, and at what size⁠· Fourth straight session of foreign futures buying⁠· Fourth straight session of program selling If the selling remains concentrated in large IT names, the index can stay heavy while the rest of the market rises. If foreign selling spreads into mid-caps, that adds downside weight
BreadthWhether KOSDAQ holds the 850 level⁠· Whether advancers lead for a seventh straight session⁠· Whether Samsung Electronics rebounds from KRW230,000 and SK Hynix from KRW1,420,000 Broad breadth + no simultaneous sharp selloff in multiple top market-cap names would add upside weight

Possible next paths depending on foreign cash flows and any KOSDAQ retracement
Return of Large CapsForeign selling narrows + Samsung Electronics and SK Hynix rebound → test the 6,365–6,394 band; a breakout would put 6,550.94 as the next reference level

RetracementProfit-taking after KOSDAQ's one-day surge + foreign selling remains above KRW1tn → retest 6,232.45; a break opens room toward 6,158.73

The assessment will consider the closing direction together with the breadth of foreign selling.

One-Line Glossary
sidecar
A circuit-breaker mechanism that suspends program-trading quotes for five minutes when index futures move sharply. The trigger conditions differ between KOSPI and KOSDAQ. For KOSPI, KOSPI200 futures must move at least ±5% for one minute. For KOSDAQ, KOSDAQ150 futures must move at least 6% and the cash index at least 3%. On Aug. 10, a KOSDAQ buy-side sidecar was triggered at 09:50; KOSPI did not trigger one.
Limit Up⁠· Limit Down
The maximum daily price move of ±30%. On Aug. 10, 11 KOSDAQ stocks hit limit-up; no KOSPI stocks hit limit-up, and neither market had a limit-down stock.
Employment Report
Monthly labor-market data released by the U.S. Department of Labor. Nonfarm payrolls and the unemployment rate are the key figures and are widely used as market benchmarks. The July report was released on the night of Aug. 7, with nonfarm payrolls down by 23,000.

The share of the working-age population that is either employed or actively seeking work. If this rate falls at the same time, the unemployment rate alone becomes less informative about labor conditions.
CPI⁠· PPI
CPI is the Consumer Price Index and PPI the Producer Price Index. Both are released monthly by the U.S. Bureau of Labor Statistics, with markets typically focusing on CPI first. July data are due on the nights of Aug. 12 and Aug. 13.
Russell 2000
An index of 2,000 U.S. small- and mid-cap stocks. It is rate-sensitive and often outperforms large-cap indexes when rate pressure eases.
SOX
Philadelphia Semiconductor Index (SOX), a key gauge of global semiconductor stocks
consensus⁠· guidance
Consensus is the average of brokerage forecasts; guidance is the company's own outlook for the next quarter. On earnings days, share prices often react more to guidance than to the reported quarter.
Short Selling
Selling borrowed shares to bet on a stock decline. KOSPI short selling of KRW1.36tn on Aug. 10 equaled 5.4% of combined KRX+NXT turnover. The KRW18.84tn KOSPI turnover figure in the body is KRX-only, so the denominators differ.
Program Trading
Automated orders that buy or sell multiple stocks at once, an important route through which indexes and investor flows move. Because program trades are already included in investor-level flow data, they are not added separately.
Arbitrage⁠· Non-arbitrage
Arbitrage program trading exploits price differences between cash and futures; non-arbitrage refers to other program trading such as index-tracking orders. Non-arbitrage is a major channel for foreign and institutional cash-equity orders.
Basis⁠· Cash-Futures Closing Basis
Basis is futures price minus the cash index. A positive value is contango, the normal structure in which futures trade above cash; a negative value is backwardation. But the cash market closes at 15:30 and KOSPI200 futures at 15:45, so simply subtracting the two closing prices does not produce a same-time basis. That is why this report calls it the closing spread and does not use it as a directional signal.
Onshore Daytime Close
The final USD/KRW transaction in the domestic FX daytime session (09:00–15:30).
Base Exchange Rate
The benchmark exchange rate published as a volume-weighted average of interbank transactions. Used here for JPY/KRW.
Sector⁠· Theme Change
Sector indexes are market-cap weighted, while theme returns are simple averages of constituent stocks. Because the methodologies differ, even identically named groups can show different returns, and themes with fewer constituents can produce larger moves. Where values differ, this report uses the sector figure as the reference.
Market Breadth
The share of stocks that advanced, rather than the index itself—a gauge of how broadly gains or losses are distributed.
Materials, Parts & Equipment
A Korean shorthand for materials, parts and equipment suppliers. In semiconductors, it generally refers to companies supplying materials and equipment to large memory-chip makers; many are listed on KOSDAQ.
