Global Backdrop — Overnight U.S. Market

• All three major U.S. indices down (May 15): Dow Jones fell 500+ points, S&P 500 and Nasdaq were dragged down by tech weakness and soaring Treasury yields, halting a seven-week winning streak. S&P 500 barely held onto seven weeks of weekly gains, though it closed lower on a daily basis.
• 10-year Treasury yield hits year-to-date peak: Surging oil prices and renewed inflation fears sent the 10-year U.S. Treasury yield to its highest level this year. Market anxiety about potential Fed rate hikes weighed heavily.
• Trump-Xi Beijing summit ends with no major announcements: Two days of talks concluded without headline-grabbing outcomes, triggering market disappointment selling. Investment sentiment that had relied on AI and tech rally reversed into oil spike and inflation panic.
• WTI crude surges: Reignites global inflation concerns, pushing back expectations for Fed rate cuts—emerges as a key variable.
• Sharp reversal after May 14 record high in New York: Led by Cisco, S&P 500 and Nasdaq notched consecutive all-time highs and Dow broke above 50,000 for the first time since February. On May 15, all gains were surrendered in a single session.

Dominant Sectors & Themes

Priority 1: Semiconductors & AI — Surge Followed by Collapse, Epicenter of Losses

• Movement: Samsung Electronics and SK Hynix, the #1 and #2 market-cap stocks, led the charge that breached 8,000, but became the primary targets of massive foreign selling, collapsing sharply. After rallying +129% YTD for Samsung and +191% for SK Hynix on AI investment fever, the aftershock is severe.
• Key holdings:
  • Samsung Electronics (005930) — Spearheaded the 8,000 rally, then hammered by foreign dumping
  • SK Hynix (000660) — Surged intraday only to plunge on foreign selling; KB Securities had just lifted its target price to ₩2.8 million (from ₩2 million) the day prior before the reversal hit
  • Other AI and semiconductor component plays — Fell in tandem
• Checkpoint: Global AI demand remains intact, but valuation overheating concerns collide with foreign profit-taking. Brokerages cite Samsung Electronics targets of ₩430K–₩500K, SK Hynix targets of ₩2.75M–₩3.1M, though near-term fund flow disruption is a wild card.

Priority 2: Battery, Auto Parts, Power Equipment — Rotation Gains Fading into Broad Selloff

• Movement: On May 14, as semiconductors took a breather, battery, auto parts, and power equipment rotated into favor and posted strength (Seoul Economic Daily report), but on May 15 all joined the broad rout.
• Key holdings: KB Securities cited a KOSPI target of 10,500 on May 15, positively evaluating rotation beneficiaries
• Checkpoint: If semiconductor fatigue eases, battery and power sectors could resurface. However, if broad foreign liquidation persists, upside is capped.

Priority 3: Global Inflation & Rate-Sensitive Sectors — Pressured by Bond Yield Spike

• Movement: Cascading effects from 10-year Treasury hitting year-high yields have weighed on rate-sensitive names (utilities, real estate, high-P/E growth stocks) across the board.
• Checkpoint: Renewed Fed rate-hike expectations act as valuation headwinds. Rising oil → energy and refining benefit somewhat vs. consumer discretionary hit.

Key Holdings Response Guide

This guide draws on brokerage reports and public filings for reference price levels only. All investment decisions remain your sole responsibility.

Samsung Electronics (005930)

• Today's close / change: Crashed sharply after breaching 8,000 — real-time confirmation needed
• Fund flows: Massive foreign net selling (primary driver of KOSPI collapse), with some institutional defensive buys
• Fundamental trigger: Memory supercycle expected to persist; domestic brokerages successively raised targets — most reports cite ₩430K+, some push ₩500K
• Brokerage targets / support & resistance: Multiple houses target ₩430K–₩500K range. 52-week box ceiling around 8,000 KOSPI levels pre-breach as reference
• Risk factors: ① Extended foreign exodus could prolong liquidity drought ② Further U.S. Treasury rally could reignite high-valuation pressure
• Response scenarios:
  • Favorable: Foreign selling stabilizes, institutions and retail lead rebound; watch for prior session close recovery
  • Adverse: KOSPI re-enters 7,500 zone, foreign net selling persists; monitor key support breaks

SK Hynix (000660)

• Today's close / change: Rallied then crashed intraday — real-time confirmation needed
• Fund flows: Massive foreign net selling, some institutional accumulation
• Fundamental trigger: KB Securities dramatically raised target from ₩2M → ₩2.8M on May 12 (steep memory pricing + earnings upgrade). YTD surge of +191% marks a spectacular outlier
• Brokerage targets / support & resistance: KB Securities ₩2.8M, broader brokerage range ₩2.75M–₩3.1M
• Risk factors: ① Heavy profit-taking pressures after short-term spike ② Potential AI demand momentum fade warning signals could evaporate upside driver
• Response scenarios:
  • Favorable: Foreign selling eases, global AI investment momentum reconfirmed; targets upper range again
  • Adverse: Foreign net selling extends past two days; further near-term pullback likely; watch ₩2.4M–₩2.5M support zone break

Battery, Power Equipment Leaders (LG Energy Solution & Rotation Candidates)

• Today's close / change: Posted rotation gains May 14, then joined May 15 collapse
• Fund flows: Short-term rotation buy interest → profit-taking on crash mixed together
• Fundamental trigger: Fatigue-driven rotation out of semiconductors into battery, auto parts, power gear anticipated (Seoul Economic Daily report); KB Securities' ₩10.5K KOSPI target and mid-to-longer-term sector broadening thesis remain valid
• Brokerage targets / support & resistance: Individual report data pending; reference recent 52-week highs and lows
• Risk factors: ① Sustained broad foreign exit could limit rotation tailwinds ② Global rate spike pressures all growth valuations
• Response scenarios:
  • Favorable: Once semiconductor pullback stabilizes and rotation resumes, relative strength likely
  • Adverse: Broad market weakness persists; copycat selling inevitable; monitor sectoral ETF support breaks

Must-Watch Events for Tomorrow

• 🇺🇸 Nvidia earnings release (expected mid-May; confirm exact timing): Global barometer for AI chip demand. Earnings surprise directly shapes Samsung Electronics and SK Hynix trajectory
• 🇺🇸 U.S. Producer Price Index (PPI) and Consumer Sentiment Index: Reports expected May 15–16. Inflation persistence signals would reignite Fed rate-hike anxiety, potentially triggering fresh foreign liquidation in Korean equities
• 🇰🇷 Foreign fund flows direction (Monday May 16 market open): Net buying or selling on the first trading day after the weekend will be decisive for near-term KOSPI direction
• 🇰🇷 Bank of Korea monetary policy committee calendar: Monitor for any policy stance shifts in response to U.S. rate pressures (confirm exact schedule via BoK official calendar)
• 🌐 Trump-Xi summit follow-through: Any trade deal announcements could directly impact Korean exporters and semiconductor supply flows

One-Line Strategy Memo

With KOSPI's historic 8,000 breach followed by a ₩2.7 trillion foreign fire sale, a risk-off shift is unavoidable in the near term. As the semiconductor and AI rally unwind from overheating, hold 7,500 as your critical watchline and stay defensive on new buys until foreign flows turn positive. Battery and power equipment rotation candidates merit nibbling only after foreign outflows ease, using stabilizing U.S. Treasury yields as a leading signal.
