Macro Dashboard

Indicator	Level	5-Day Δ	Signal
KOSPI	8,476.1	+8.0%	▲ Large-cap bid
KOSDAQ	1,074.8	−7.4%	▼ Weak
USD/KRW	1,506	−0.5%	→ Stable
VIX	15.8	−4.8%	● Calm
US 10Y	4.46%	−10 bps	→ Stable
Brent	$91.0	−8.6%	▼ Soft

Regime: Korea = Bear | US = Bull. The 15.4pp gap between KOSPI and KOSDAQ over five sessions is the headline divergence. US breadth (50MA: 57.2%) stays constructive while Korea’s remains thin (50MA: 22.7%, 200MA: 37.5%). Brent’s pullback reduces one inflation tail risk; the dollar is steady near 1,506.

Market Wrap

Today’s session looked strong at the index level and weak everywhere else. KOSPI held near 8,476, but only 439 of 2,487 tracked stocks advanced against 1,846 decliners. The ADR proxy printed 23.8 — deeply below neutral — and the average stock fell 1.22% on ₩27.9 trillion in total turnover. This was not a broad rally. It was a handful of large-cap moves lifting the headline number.

The dominant theme was a sharp re-rating in consumer electronics and IT services. LG Electronics (066570.KS, +29.93%) posted one of the largest single-day moves in the KOSPI on extraordinary ₩2.55 trillion volume; LG Innotek (011070.KS, +28.57%) followed on ₩1.88 trillion. Samsung SDS (018260.KS, +20.32%) and NAVER (035420.KS, +14.15%) also surged, with institutions stepping in behind both. Hyundai Mobis (012330.KS, +11.95%) and Samsung Electro-Mechanics (009150.KS, +15.04%) extended strength into the auto-component and electronics supply chain.

Institutional flow was decisive in the large caps. Samsung Electronics (005930.KS, +5.84%) attracted ₩1.67 trillion in institutional buying even as foreigners sold. Hyundai Motor (005380.KS, +6.79%) and NAVER drew simultaneous foreign and institutional buying — the cleaner co-buy signal on the day. In contrast, SK Hynix (000660.KS) absorbed ₩1.03 trillion in foreign net selling despite a modest +1.92% gain, with retail partially absorbing the supply.

Weakness was broad and indiscriminate outside the large-cap names. Display components, biotech, and smaller materials stocks dominated the decline list, with several shedding 12–21%. Sector rotation rather than macro panic — but breadth at 23.8 ADR leaves no ambiguity about the Bear-regime reading for Korea at the stock level.

Today’s Quality Re-Rating Candidates

Top 3 in Focus

VM (089970.KQ) — Semiconductor Equipment, KOSDAQ VM manufactures deposition and etch equipment for semiconductor fabs. It is the only name today topping both the five-screener overlap list and the meta-screener ranking simultaneously. The numbers are striking: operating profit +387% YoY, margin expansion of +29.3pp, and a PEAD score that ranks #1 among 29 drift candidates. Foreign and quality-institutional buyers absorbed roughly ₩24.1 billion in retail selling over five sessions. The Q1 2026 quarterly report filed on DART (May 15) provides the most recent financial baseline. Key question: whether the margin step-up is structural or a one-quarter outsized project mix.

Gigavis (420770.KQ) — Automated Optical Inspection, KOSDAQ Gigavis builds AOI (automated optical inspection) systems used in PCB and panel quality control — a critical link in the electronics supply chain. Four screeners cleared; PEAD is the only framework it misses, likely because the drift window does not yet show a confirmed price reaction. Revenue doubled (+101% YoY) and operating profit expanded +777%, with a +29.9pp margin jump. Smart Money Quality ranks it #1 among nine names in its universe. The elevated PER (116x) reflects growth expectations already priced in; the next earnings disclosure on DART and consensus revision trajectory are the key monitors. An insider ownership filing was made on May 22.

DB Hi-Tek (000990.KS) — Analog/Power Foundry, KOSPI DB Hi-Tek is Korea’s largest dedicated analog and power semiconductor foundry. It cleared all five screeners — matching VM on coverage breadth — but at a more moderate inflection profile: ROE 11.8%, OP +45% YoY, margin +3.0pp. The stock fell -4.53% today alongside broad sector weakness, yet foreign buyers net-bought against quality-institutional selling — a flow split worth watching. Two items require verification before this candidate advances: (1) a DART filing today for a subsidiary operational suspension event and (2) the risk classification note from the Kiwoom surface overlay (quality institutional flow negative, short interest context). The 5-day foreign + quality-institutional net buy of ₩146.0 billion remains the supporting evidence.
