Regime Verdict — KR: Bull | US: Bull | Stance: Aggressive Expand

Both markets confirmed Bull on April 22 after a brief Neutral interlude. Breadth remains constructive: 61.4% of the KR universe trades above the 50-day MA, 58.6% above the 200-day. The 4.2-percentage-point gap between KOSPI (+4.6%) and KOSDAQ (+0.4%) over the past five sessions signals a large-cap quality tilt. Watch for a Neutral relapse — an identical setup on April 17 and 21 flipped to Neutral within 24 hours.

Market Wrap

Thursday’s Korea stock market session extended a week-long recovery that has pushed the KOSPI back above 6,475 — a level not seen since early April. The character of today’s trade was a quality-led, large-cap advance: broad enough to sustain a Bull macro regime verdict but narrow enough to leave small-caps virtually unchanged.

Large-caps carried the load. The KOSPI’s five-session gain of 283 points (+4.6%) dwarfs the KOSDAQ’s meager +4.3-point uptick (+0.4%) over the same window, a 4.2-percentage-point divergence that reflects institutional rotation toward liquid, high-quality names rather than a broad risk-on sweep. Market breadth of 61.4% above the 50-day MA confirms participation is real but not euphoric.

Semiconductors and industrial infrastructure dominated themes. The screener data is heavily skewed toward special-purpose machinery and semiconductor-adjacent equipment manufacturers posting triple-digit revenue growth — a sign that investors are pricing in continued capex buildout in AI infrastructure and power/energy grids. Power-equipment and transformer names (Sanil Electric, Semyung Electric, Boseong Powertech) cluster at the top of quality rankings alongside semiconductor blue-chips, suggesting the market is rewarding two adjacent capex cycles simultaneously: AI compute and the grid infrastructure needed to power it.

Foreign and institutional flows tilted supportive. The Discovery sub-signal within the screener has been running at 100/100 for 17 consecutive sessions — an unusually persistent momentum reading that typically reflects sustained foreign or institutional accumulation in the top-tier universe. Combined with VIX at a manageable 19.6 and a stable won (1,482/USD, barely moved), the external backdrop removed the tail-risk premium that had weighed on sentiment in mid-April.

Risks on the radar. Brent’s +2.0% five-session move to $97.4 bears watching: at these levels, imported inflation begins to pressure the Bank of Korea’s already cautious easing calculus. A DXY firming toward 99 alongside oil above $97 is an uncomfortable combination for an import-heavy economy. The previous Bull-to-Neutral regime flip (April 22) was short-lived, but the pattern of brief Bull windows followed by retreats suggests the current leg needs macro confirmation to extend.

Thursday Screener Spotlight: Quality Compounder

Methodology: The Quality Compounder screen filters the 2,722-stock KR universe for the intersection of high fundamental quality (ROE, operating margin, low debt), durable revenue growth, and price trend confirmation (RS85+, Near-52W High). Today 179 names cleared the bar; the top 20 are ranked by a composite strategy score (avg 0.905 for this cohort).

Top 3 in Focus

SK Square (402340.KS) — Score 0.966, P/E 10.9x SK Square is the investment holding company that owns a ~20% stake in SK Hynix along with a portfolio of tech subsidiaries (11Street, SK Shieldus, Incross). The 84.1% operating margin reflects the holding-company structure — essentially a leveraged play on SK Hynix’s semiconductor cycle at a significant NAV discount. At 10.9x trailing earnings, it is the cheapest name in the top-20 cohort by a wide margin, and its near-all-time-high RS (99.1 percentile) suggests the market is beginning to close that discount. The +77.8% revenue growth flags meaningful portfolio monetization on top of the HBM cycle tailwind.

Sanil Electric (062040.KS) — Score 0.930, P/E 43.2x Sanil manufactures power transformers and distribution equipment, sitting at the intersection of two secular capex waves: domestic grid modernization and data-center power supply. ROE of 29.2% and a 35.6% operating margin are exceptional for heavy electrical manufacturing, pointing to pricing power from a constrained supply base. Revenue growth of +50.3% YoY reflects backlog execution rather than demand pull-forward, making the 43x multiple more defensible than it appears on the surface.

Leeno Industrial (058470.KS) — Score 0.923, P/E 61.8x Leeno is the dominant Korean maker of semiconductor test sockets — the precision-machined contact pins that sit between IC chips and test equipment during quality control. With a 47.5% operating margin and ROE of 22.5%, Leeno operates a quasi-monopoly niche in a consumables-like business: sockets wear out with use, creating recurring revenue tied to wafer-out volumes. The premium multiple (61.8x) is the market paying for durability; the stock’s 95th-percentile RS confirms institutional patience with that valuation.
