Regime: KR Neutral / US Neutral — selective hold. KOSPI breadth sits at 52.8% above the 50-day MA and 23.0% above the 200-day MA: stock-picking conditions are above average, but broad momentum is absent. The 5-day KOSDAQ–KOSPI divergence of +3.6pp signals active rotation into smaller-cap earnings stories. Primary headwinds: the US 10-year at 5.24% (up 27bp over five days) and a net ₩2.1 trillion in market program selling pressing large-cap index weights.


Market Wrap

Today was a distribution session with selective pockets of strength. Market breadth was clearly negative — 707 advances versus 1,624 declines, ADR proxy 43.5, average stock change −0.66% — yet semiconductor equipment and specialty-tech names drew simultaneous foreign and institutional buying.

Construction was the weakest sector. 대우건설 (047040.KS, −7.01%), 현대건설 (000720.KS, −6.10%), 삼성E&A (028050.KS, −5.70%), and GS건설 (006360.KS, −4.36%) all fell sharply. Rising US long rates pressure project-financing economics, and foreign investors were net sellers across the group. SK이노베이션 (096770.KS, −7.77%) was the single largest name on the institutional-sell list.

Battery and alternative energy also gave ground. 삼성SDI (006400.KS, −4.13%) faced institutional selling. 두산퓨얼셀 (336260.KS, −5.71%) fell even as foreigners bought — institutions and domestic accounts took the other side. LG에너지솔루션 (373220.KS, −3.16%) and 한화솔루션 (009830.KS, −2.55%) added to the ESS/solar weakness.

Semiconductor equipment and PCB names were the clear exception. HPSP (403870.KQ, +8.93%) appeared simultaneously at the top of both the foreign-buy and institutional-buy leaderboards — a rare same-session double that flags genuine accumulation. 코리아써키트 (007810.KS, +7.39%) also drew institutional inflows. On the foreign side, 삼화콘덴서 (001820.KS, +8.62%), 테스 (095610.KS, +5.50%), 테크윙 (089030.KS, +3.55%), and 태성 (323280.KS, +13.33%) were notable buys.

The macro overlay: program selling dominated. Net market program flow was −₩21,176 billion (non-arbitrage −₩21,540 billion), with a futures basis of +7.95 and open interest declining 578 contracts — institutional de-risking rather than fundamental deterioration. ETF net creation of +₩437 billion provided a partial offset. KOSDAQ’s relative outperformance is consistent with this: smaller-cap earnings names are less exposed to index-level program redemptions.


Today’s Quality Re-Rating Candidates

Note: Today’s raw screener cross-tab includes only the PEAD screener as a standalone source; the intersection table registers no 2+ raw-screener overlaps. The KR Meta Screener — which aggregates quality, money-flow, cycle, earnings, consensus, and official-catalyst signals across all daily runs — is therefore the primary ranking tool for today’s candidates.

The meta screener covered 138 tickers. Names reaching five or more independent evidence families warrant the closest attention.

Deep Context: Top 3

1. Samsung Electronics (005930.KS) — Meta Score 78.7

Samsung is the session’s highest-conviction meta candidate, clearing seven independent evidence families — the broadest signal cluster in today’s universe. The quality layer checks out: ROE 10.7%, operating profit +33.2% YoY. The cycle re-rating signal shows operating margin expanded +2.2pp. The flow picture is telling: retail was a net seller of roughly −₩4.19 trillion over the recent window, and that supply was absorbed by foreign investors and quality institutions — a pattern the screener treats as a positive transfer-of-ownership signal. PEAD and RS80-not-late confirmations add timing support on the price axis. Nine recent DART filings are routine (insider and major-shareholder disclosures); no fresh operational catalyst is flagged. What to check next: whether the margin expansion trajectory is accelerating heading into the next earnings cycle.

2. Gigavis (420770.KQ) — Meta Score 70.8

Gigavis carries today’s strongest earnings-surprise story: operating profit +777% YoY, margin expansion of +29.9pp, and a consensus upward revision with a composite z-score of +0.75. The PEAD setup is constructive — the stock is 32.9% below its 52-week high while trading 14.7% above its 50-day MA, suggesting drift room remains without the blow-off risk that disqualifies many PEAD candidates. A DART supply-contract filing from September 15 provides an official catalyst anchor for the revenue improvement story. This is a display-inspection equipment name where earnings, analyst revisions, and price momentum are aligning simultaneously — the combination that historically sustains PEAD. Caution: no short-interest risk flag from Kiwoom today, but the small-cap liquidity profile warrants sizing discipline.

3. Samsung Electro-Mechanics (009150.KS) — Meta Score 68.1

Samsung Electro-Mechanics passes Quality Compounder (ROE 7.4%, OP YoY +24.3%), Cycle Re-rating (margin +0.9pp), and PEAD filters, with retail supply of approximately −₩391 billion absorbed by foreign and institutional buyers. What makes the timing notable: a same-day DART supply-contract filing (September 29) and a subsidiary capex decision disclosure from the prior session — two official catalyst signals within 48 hours. The stock sits 32.7% below its 52-week high, leaving meaningful re-pricing room if the contract ramp confirms the margin trajectory. Key risk to monitor: consensus has not yet revised meaningfully (no Consensus Up screener hit), so the investment case rests on whether the DART catalysts translate into forward estimate upgrades over the next two to four weeks.
