| Indicator | Level | 5-Day Δ | Signal |
|---|---|---|---|
| KOSPI | 8,228.7 | +14.2% | Bull |

Both Korea and US regimes are confirmed Bull. KOSPI’s five-day advance of +14.2% reflects a sustained large-cap recovery; KOSDAQ’s +7.3% points to broadening participation in growth names. VIX at 16.9 is calm. Brent’s −8.1% five-day slide reduces cost-push pressure across Korean industrials and manufacturers. The overall stance is aggressive expansion.
Market Wrap (most recent session data: May 22)
The May 22 session was best described as selective risk-on with notable stock-level dispersion rather than a uniform broad rally. KOSDAQ surged over +4%, outpacing KOSPI’s modest +0.5%, as money rotated into smaller-cap growth stories across pharma/biotech, power/energy, and semiconductor component makers. KOSDAQ breadth reached 36.0% of names above their 50-day MA with 99 names clearing the full quality screen — improving, but still a stock-picker’s market rather than a rising-tide session.
The single strongest performer was Samsung Electro-Mechanics (009150.KS), up +11.3% on the day and +32.7% over five sessions. A Morgan Stanley note circulating across financial channels raised its forecast for high-performance ABF substrate shortage rates from 15% to 22% by 2030, directly reinforcing the investment thesis for both advanced PCB substrate and semiconductor packaging component names. Daeduck Electronics (353200.KS) rose +3.4% on the same thematic read, though foreign and institutional flows split — a divergence worth watching before treating it as confirmed smart-money entry.
On the other side of the ledger, foreign investors sold roughly −1.01 trillion won in Samsung Electronics (005930.KS) on the day, accompanied by program selling of approximately −998 billion won. This came despite Mirae Asset naming both Samsung Electronics and SK Hynix (000660.KS) as H2 re-rating candidates in its latest top-picks note. The simultaneous sell pressure indicated the market needed more confirmation before committing to the memory re-entry narrative — a reminder that broker upgrades and actual capital allocation are different things.
Sector flow summary: biotech/pharma, power infrastructure, and semiconductor equipment components were the strong axes. Large-cap memory semiconductors, telecoms, and prior-session surge names faced profit-taking. Discovery-level names flagged by the daily screener included Jusung Engineering (036930.KS, +20.95%, foreign and institutional co-buy) and Symtec (036070.KS, +5.02%, ABF/PCB axis co-buy with both foreign and institutional participation).
Today’s Quality Re-Rating Candidates (screener data: May 27)
The meta-screener ranks SK Square (402340.KS) first with a score of 84.8 — a meaningful gap above the field. The raw screener-overlap table, by contrast, places HD Hyundai Heavy Industries (329180.KS), EO Technics (039030.KQ), and Hanwha Ocean (042660.KS) first on four screener hits each. The meta-screener order is preferred here: HD Heavy and Hanwha Ocean both miss the Quality Compounder layer, carry debt ratios of 180% and 226% respectively, and have elevated short interest. The meta framework penalizes that profile, pulling their composite scores below names with smaller but structurally cleaner businesses.

SK Square (402340.KS) — Meta #1, Score 84.8
SK Square is the investment holding entity for SK Telecom’s technology assets, with SK Hynix as the primary NAV driver. The quality case is unusually strong for a holding company: ROE of 31.9%, operating profit up +124.8% YoY, and a debt ratio of just 9.1%. What elevates it today is the flow structure — retail investors distributed approximately −194.9 billion won over five days while foreign capital and quality institutional accounts absorbed that supply (+11.5 billion won net). A share buyback completion report was disclosed via DART on May 13 (a concrete return-of-capital catalyst). This combination of quality fundamentals, clean balance sheet, active buyback, and smart-money absorption is the highest-priority configuration in the framework. Next check: Does the retail-to-institutional rotation persist, and does the NAV discount to SK Hynix’s recent rally narrow on volume?
Gigavis (420770.KQ) — Meta #2, Score 73.0
Gigavis manufactures automated optical inspection equipment used in semiconductor and display processes — a direct beneficiary of rising advanced packaging and HBM capex cycles. The earnings data is striking: operating profit up +777% YoY, revenue more than doubled (+100.6%), and margin expanded 29.9 percentage points. The PEAD composite score of +2.20 is the highest in the entire Tier A PEAD universe for this session, suggesting the market has not yet fully re-priced the earnings inflection. It clears Quality Compounder (#5), Cycle Rerating (#12), and PEAD (#1 rank). The 52-week high gap stands at 13.2%, leaving meaningful drift room. Next check: Volume confirmation as the stock approaches prior highs, and whether the margin expansion is durable into the next quarter.
HD Hyundai Heavy Industries (329180.KS) — Meta #4, Score 64.8
Korea’s largest shipbuilder hits four screeners on the strength of operating profit up +188.9% YoY and a margin expansion of +6.7pp. Cumulative five-day foreign and quality institutional buying totals +164.1 billion won as retail investors supplied −99.7 billion won — a classic smart-money absorption pattern. Four official DART catalyst filings (including a preliminary earnings disclosure) landed in the 21-day lookback window. This name fits a momentum/earnings re-rating frame rather than a pure quality compounder angle. Key caution: Short interest at 17.9% is the highest among the top-ten candidates, and the debt structure is leveraged. Position sizing discipline is warranted.
