Indicator	Level	5D Δ	Signal
KOSPI	9,114.55	+4.5%	Outperforming
KOSDAQ	968.40	−4.9%	Underperforming

Regime: KR = Bear · US = Neutral. Breadth tells the real story: only 13.7% of KOSPI names trade above their 50-day MA, 25.6% above their 200-day MA. The 9.4 percentage-point five-day spread between KOSPI and KOSDAQ is the session’s defining macro signal.

Market Wrap

Today’s Korea stock market printed a tidy KOSPI +0.69% to 9,114.55 — but the surface is cleaner than what lies underneath. The session was almost entirely a large-cap semiconductor story. SK Hynix (000660.KS) surged +5.6%, extending its extraordinary five-session run to +27.6%. Samsung Electronics (005930.KS) closed marginally lower on the day (-0.1%) but remains +4.9% over five sessions. Strip those two names and the session read much closer to the KOSDAQ’s +0.19% — technically positive, but directionless.

The thematic engine continues to be AI infrastructure. Market commentary concentrated on HBM supply tightness and long-term supply agreement expectations around SK Hynix; AI server MLCC shortages with upward ASP revisions for Samsung Electro-Mechanics (009150.KS); and demand signals from major US hyperscalers continuing to flow through Korean supply chains. The semiconductor and AI infrastructure theme accounted for the overwhelming majority of positive news flow — roughly 30 items by Telegram monitoring — versus energy and power at 11.

Flow signals at the top of the market were mixed in a telling way. SK Hynix saw heavy foreign net selling (approximately 1.43 trillion won over five sessions) while domestic institutional buyers absorbed that flow (+1.24 trillion won net). Samsung Electronics showed both foreign and institutional net selling today, with retail as the marginal bid. On the derivatives side, program trading was negative at -2.55 trillion won, partially offset by ETF net creation of +459.9 billion won. Basis came in at +13.28.

Away from large-cap semiconductors, the session was weak. KOSDAQ breadth failed to improve. Shipbuilding, defense, and broader growth themes continued to distribute. The regime — KR Bear, US Neutral — is unchanged, and the narrow breadth underscores that this remains a stock-picker’s environment rather than a broad risk-on tide.

Today’s Quality Re-Rating Candidates

Today’s screener run across 2,711 Korea-listed names yielded just 23 Quality Compounder passes — a tight filter consistent with sub-2% breadth above the 50-day MA. The five-screener framework layers quality fundamentals, institutional and foreign flow (Smart Money Quality), operating leverage and margin inflection (Cycle Rerating), earnings improvement with smart-money confirmation (Smart Money Earnings), and post-earnings announcement drift (PEAD). Names clearing three or more screeners simultaneously are the session’s preferred research candidates.

QC = Quality Compounder · SMQ = Smart Money Quality · CR = Cycle Rerating · SME = Smart Money Earnings

Gigavis (420770.KQ) leads the scan by a wide margin — the only name to clear all five screeners with a composite meta score of 112.4. The company manufactures Automated Optical Inspection (AOI) systems used in semiconductor and display panel production. Operating profit grew +777% year-over-year as revenue doubled (+100.6%), with margins expanding nearly 30 percentage points — a textbook cycle inflection. The PEAD composite score tops the entire scan (+2.94), with the stock sitting at its 52-week high on a five-day return of +13.6%. A DART supply contract disclosed on June 15 adds a near-term catalyst layer; today’s institutional and foreign buyers are absorbing retail supply (+6.3 billion won net over five sessions). What to check next: the trailing PER of 123x embeds aggressive expectations — the critical variable is whether this is a structural shift in AOI demand or a single-customer capacity ramp.

BVM (089970.KQ) ranks #2 in the meta screener despite hitting only four screeners (no PEAD overlap), because its fundamental quality is stronger than its overlap count suggests. The meta scoring weights margin expansion and earnings trajectory heavily, and BVM’s +29.3 percentage point operating margin expansion — revenue more than doubled (+105.5%), operating income grew +387% — stands out as one of the sharpest inflection profiles in the scan. The company makes semiconductor process equipment in the CVD/ALD adjacent space. Foreign and institutional investors net bought approximately 37.6 billion won over five sessions while retail sold. No DART risk flags in the 21-day lookback. What to check next: whether the revenue doubling reflects a durable capacity expansion cycle at key customers or a lumpy project-based cycle.

DB HiTek (000990.KS) earns its five-screener count as Korea’s primary analog and power semiconductor foundry serving automotive, industrial, and consumer end-markets. Operating profit grew +45% on revenue up +23.5%, with margins recovering +3 percentage points. Five-day institutional and foreign net buying totals approximately 65.3 billion won. Two cautions are worth tracking before any deeper work: short interest at 23.4% of float creates headline risk on any guidance miss, and the PEAD composite score is mildly negative (-1.04), indicating the near-term price drift has not confirmed the earnings beat as cleanly as Gigavis. Hyosung Heavy Industries (298040.KS, ranked #7) filed both an IR roadshow notice and a supply contract amendment via DART today — worth flagging as a same-day catalyst for that name.

The breadth context matters. Fewer than 14% of KOSPI stocks are above their 50-day average. In this environment the screener framework’s job is exactly what it shows today: a compact cluster of names where business quality, institutional capital, and improving earnings are simultaneously pointing in the same direction. Gigavis, BVM, and DB HiTek are where that three-way confirmation is strongest.
