Regime: KR Bear / US Bull. Despite a violent single-session recovery, the 5-day drawdown remains severe and breadth has not healed — stocks above 50-MA: 1.6%; above 200-MA: 2.6%. The KR/US divergence persists. KR stance: reduce exposure; US: hold.


Market Wrap

Korea staged a textbook relief bounce on June 9, the session after a circuit-breaker halt forced an early close. KOSPI recovered +7.53% to 8,048 and KOSDAQ added +7.16% to 977, with the bulk of the move concentrated in semiconductors and AI infrastructure.

What drove the session. The leading edge was large-cap memory. Sell-side commentary cited three drivers: the U.S. semiconductor index rebounding overnight, sustained AI data-center capex from hyperscalers, and domestic institutional bargain-hunting at valuation support built up over months. Samsung Electronics (005930.KS) rose +9.0%; SK Hynix (000660.KS) surged +15.9%, recording the largest single-day institutional buy in the complex.

Under the hood, flows were split. For Samsung Electronics (005930.KS), institutions net-bought ₩564.9B while foreign investors net-sold ₩492.4B. SK Hynix (000660.KS) showed an even sharper divide: institutions added ₩1.84T against ₩1.36T of foreign selling. This is an institutionally-defended bounce, not a foreign-confirmed trend reversal. The operative question for June 10 is whether foreign flows rotate from distribution to accumulation, or continue offloading into institutional support.

Sector rotation. Electronics, semiconductor equipment, and medical precision were the session’s strongest axes. The clear underperformer was the AI application and IT services cluster — names that had pre-priced Nvidia partnership narratives sold off as the market rotated into the hardware layer. Within equipment, Hanmi Semiconductor (042700.KS, +9.1%) caught attention following DART supply-contract disclosures filed on June 5 and June 8, though elevated short interest and mixed institutional flows tempered the conviction read.

New breakout candidates. Samsung Electro-Mechanics (009150.KS) led daily RS rankings at 99.5 with a +18.4% session, but RSI and price-extension metrics suggest a pullback entry rather than a chase. TES (095610.KQ) and VM (089970.KQ) cleared Minervini momentum filters and topped the breakout screen simultaneously. Both are rebounding from the prior-day collapse, so the operationally conservative read is to watch whether volume holds and the breakout level defends into June 10 before sizing up.

Regime context. Today’s move does not reset the bear verdict. The KR discovery screener sits at 45/100, Day 12 of the weakness-confirmation window. This session reads as a strong mean-reversion trade, not a structural pivot. Tomorrow’s checkpoints: KOSPI sustaining above 8,000; foreign flow in SK Hynix shifting from net-sell toward flat or positive.


Today’s Quality Re-Rating Candidates

The meta screener processed 93 tickers. TES (095610.KQ) ranks first by composite score (77.6); Hyosung Heavy Industries (298040.KS) leads by raw screener overlap (4 signals). The table follows meta-screener order, with overlap count alongside for context.

Why the meta score diverges from overlap on Hyosung Heavy. Hyosung Heavy Industries (298040.KS) hits 4 screeners — the highest count today — yet lands at meta rank #3. The adjustment reflects two caution flags: (1) foreign + quality-institutional net-selling of −₩11.5B over 5 days, absorbed by retail inflows of +₩32.8B; (2) a debt ratio of 201.5%, which the quality filter penalizes. The business fundamentals are genuinely strong — ROE 21.4%, OP YoY +106.1%, margin expansion +5.1pp — but the money-flow pattern is retail-led, not institution-led. TES (095610.KQ) shows the inverse: institutional and foreign buying absorbing retail selling, the cleaner re-rating signal in current conditions.


Top 3 Candidates in Detail

TES (095610.KQ) — Meta #1, score 77.6. TES manufactures semiconductor deposition equipment (CVD and ALD systems), with direct exposure to leading-edge memory and logic fab investment cycles. The name clears all three primary screeners simultaneously: Quality Compounder (ROE 14.5%, OP YoY +50.3%), Smart Money Quality (ranked #1 in that screener), and Smart Money Earnings (also #1). Over the past 5 days, foreign and quality-institutional money net-absorbed ₩26.6B of retail selling. Two DART voluntary supply-contract disclosures — May 21 and June 5 — add a catalyst layer that the meta engine captures via its official-filing overlay. Key risk: Kiwoom flow data shows relatively light total institutional volume (rank #364), and foreign ownership sits at just 10.4%, meaning the re-rating is in early stages. Next check: whether today’s breakout closes above prior resistance on sustained volume in the June 10 session.

Hyosung Heavy Industries (298040.KS) — Meta #3, overlap #1. A power electronics and heavy electrical equipment manufacturer with growing exposure to grid infrastructure, EV charging, and data-center power systems. The 4-screener sweep is genuine — operating leverage spread of +84.1pp, margin expansion +5.1pp, OP YoY +106.1%, and net income growth of +125.6% — placing it at #2 in both the Smart Money Quality and Smart Money Earnings screeners. The primary caution is the current flow structure: retail is driving the bid, not foreign or institutional smart money. Short interest at 12.4% adds a short-squeeze dimension if flow turns. The re-rating story is intact; the timing read depends on whether institutional buying accelerates off today’s bounce.

Korea Circuit (007810.KS) — Meta #5, overlap rank #3. A multilayer PCB manufacturer in the semiconductor supply chain, appearing in 4 screener signals: Smart Money Quality (#4), Smart Money Earnings (#3), Cycle Rerating (#10), and PEAD Tier C (OP YoY +262.3%, margin +5.9pp). The PEAD composite score is the only positive-surface reading among today’s candidates (+0.29), backed by an RS percentile of 98.8 and a 52-week high gap of just 1.6% — the stock is effectively at a breakout pivot. Foreign and quality-institutional net buying of +₩23.7B over 5 days against retail selling of −₩31.2B is the cleanest accumulation pattern in this screen. What to verify next: PCB order-flow commentary for Q2 visibility, and whether the 52-week breakout level holds with volume.
