Indicator	Level	5-Day Change	Signal
KOSPI	8,639.4	+5.5%	Large-cap supported
KOSDAQ	1,049.7	−5.0%	Broad weakness
USD/KRW	1,532	+2.5%	KRW under pressure

Brent	$96.2	+1.3%	Mild creep

Regime: KR Bear / US Bull. The 10.5pp KOSPI–KOSDAQ divergence is the headline. Large-cap exporters are holding; domestic small-caps are not. A weakening KRW and rising oil add macro drag for consumer-facing names.

Market Wrap

Source: KR Market Snapshot (same-day DB, 2026-06-04). Full close briefing unavailable for this session.

Breadth tells the story plainly: 916 stocks advanced, 1,043 declined, 203 were flat — across 2,162 names with ADR proxy 87.8 and total turnover of just 2.44 trillion KRW. This was not a broad rally. It was a rotation.

The session’s defining trade was a foreign pivot up the semiconductor value chain. Foreigners sold Samsung Electronics (005930.KS, −2.5%) for −4.40 trillion KRW and SK Hynix (000660.KS, −2.6%) for −1.03 trillion, while domestic institutions stepped in to absorb Samsung (+1.16T KRW net buy). Separately, SK Telecom (017670.KS) fell −13.0% with heavy foreign selling — no apparent fresh negative, but the magnitude suggests real position reduction.

The proceeds appear to have rotated upstream. Equipment names printed circuit-limit or near-limit gains on meaningful foreign inflows: Wonik IPS (240810.KQ, +29.9%), Jusung Engineering (036930.KQ, +27.2%), VM (089970.KQ, +28.2%), Inotechnics (039030.KQ, +14.8%), and Hanmi Semiconductor (042700.KQ, +10.3%) were all in the top foreign buy list. Samsung C&T (028260.KS, +10.2%) drew notable foreign buying as well, though institutions were simultaneous sellers there — a tug of war rather than a clean signal.

Outside semiconductors, strength was thin. Defense names reversed: Korea Aerospace Industries (047810.KS, −3.7%) and Hyundai Rotem (064350.KS, −5.1%) gave back recent gains as foreign sellers moved on after a strong run. Consumer and platform names continued to bleed — BGF Retail (282330.KS, −2.6%), NHN (181710.KS, −12.0%), and Robothiz (108490.KQ, −15.2%) all saw volume-accompanied declines. Robothiz’s −15% slide was the sharpest distribution event of the session.

Session character: selective strength in upstream semiconductor equipment, AI-related equipment, and a few small-cap speculative names (마음AI 377480.KQ +30%, 팸텍 271830.KQ +30%). Broad KOSDAQ was the loser. The KR Bear regime verdict reflects the underlying: unless you were in the right equipment or large-cap defensive corner, the tape was actively negative.

Today’s Quality Re-Rating Candidates

The meta screener ranked 102 tickers and produced 20 article candidates. The framework prioritizes names hitting multiple independent screeners — Quality Compounder (business quality), Smart Money Quality (institutional flow), Cycle Rerating (margin-expansion leverage), Smart Money Earnings (earnings inflection + flow), and PEAD (post-earnings drift).

Top 3 Candidate Context

기가비스 (420770.KQ) — Meta #1, ×5 Screeners Gigavis makes inspection and metrology equipment for advanced semiconductor packaging — a direct beneficiary of HBM and CoWoS capacity build-outs. It is the only name today alongside VM to clear all five independent screeners, giving it the highest meta score in the universe (114.6). The numbers behind the ranking are striking: operating profit grew +777% YoY with margin expansion of 29.9pp and revenue up +101%. Today (June 4), a new single-supply contract was disclosed via DART — a hard catalyst that explains why foreign and quality-institutional buyers absorbed 194.6B KRW of retail supply over the past five sessions (+165.8B net F+QI). At a trailing P/E of 108x, the valuation prices in a great deal of continuation; the contract materiality and client identity are the key verification items before treating this as anything more than a monitored screener candidate.

브이엠 (089970.KQ) — Meta #2, ×5 Screeners VM manufactures CVD (chemical vapor deposition) equipment used in DRAM and NAND fabrication. Its screener profile is a near mirror of Gigavis — operating profit +387% YoY, margin up 29.3pp, all five screeners cleared — but at a lower score (108.7) because its Quality Compounder rank (RS #6 vs #4) is slightly softer. Today’s +28% session move was accompanied by both foreign and institutional buying absorbing 387.7B KRW of retail supply. The PEAD composite score of +1.43 is the highest in Tier A, and at 0% below its 52-week high, the drift has no technical ceiling in the near term. A large-block holder filing appeared June 2 — monitoring for overhang is warranted. Next check: CVD order backlog, customer fab-type breakdown (DRAM vs NAND vs logic).

이오테크닉스 (039030.KQ) — Meta #4, ×4 Screeners Inotechnics makes laser-based processing and dicing systems for semiconductor and PCB manufacturing. It cleared four screeners and, critically, was the top-ranked foreign net buy in the equipment cohort over five sessions (+872B KRW F+QI net) — the single largest institutional inflow among screened names today. Operating profit grew +159% YoY with 11.5pp margin expansion; revenue grew +19%. The Kiwoom surface flags elevated but not extreme volume (거래대금 rank #100), and there is no short-interest concern. The caution worth noting: foreign ownership stands at 24.3% and quality-institutional flows turn slightly negative on the margin on a single-day basis, suggesting the five-day accumulation may be approaching a distribution phase. Next check: laser demand from HBM substrate and advanced packaging customers, and whether today’s +14.8% move was concentrated in one institution or distributed.
