1. Weekly Summary
This week's bull run was driven by two independent tailwinds firing simultaneously. First, expectations of a U.S.–Iran 60-day ceasefire MOU sent WTI crude down -9.57% ($87.36) and Brent -11.10% ($92.05) for the week, easing energy-driven inflation pressure. This pulled the 10-year Treasury yield from 4.56% to 4.45% and the 30-year from 5.06% to 4.99% (the first sub-5% close since 2007), improving the discount rate for growth stocks. Second, the AI infrastructure earnings supercycle was validated across the entire stack — chips to memory to servers to software — as Micron crossed a $1 trillion market cap (+18%), Dell AI server revenue surged +757%, and Snowflake gained +39.5% in a single session. The result: the S&P 500 closed at a 9th consecutive record high at +1.43% (7,580.06), the Nasdaq rose +2.39% (26,972.62), and XLK gained +5.89% to lead all sectors. In Korea, Samsung Electronics shipped the world's first HBM4E 12-stack modules and SK Hynix's DRAM price broke $20 for the first time, propelling the KOSPI to an all-time high of +8.01% (8,476.15), with EWY +13.07% and DFEN +13.81% ranking among the top global performers.
Beneath the bullish surface, stagflation signals and an extremely narrow rally breadth lurked. April PCE accelerated to +3.8% (a 3-year high) with core PCE at +3.3%, and Q1 GDP was revised down to 1.6%, prompting bond markets to price in a roughly 50% probability of a year-end rate hike — a diametrically opposite message to equities' AI optimism. More troubling was the rally's internal structure: on 5/29, when the S&P hit a new record, only 2 of 12 sectors — tech and financials — were up, while energy (XLE -5.38%), consumer staples (XLP -2.23%), utilities (XLU -2.05%), and 7 other sectors all fell. The Russell 2000 shed -0.59% and the KOSDAQ dropped -7.43%, laying bare the global bifurcation between AI mega-caps and non-thematic small-caps. Crypto was left out of the risk-on rally, with BTC down -4.42% and crypto ETFs seeing $2 billion in outflows over two weeks.
Next week presents two macro pivot points — the U.S. May CPI on 6/10 (whether it reflects the energy base effect) and Fed Chair Waller's first full FOMC on 6/16–17 — with the final signing of the Iran ceasefire as the wildcard that will determine the oil and inflation path. If the -9.57% oil drop feeds through to May CPI and the narrow rally broadens into consumer and financial stocks, the bull market extends. If negotiations collapse (Iran continues missile strikes toward Kuwait) or AI-driven profit-taking accelerates, a correction risk emerges. Early June earnings from Broadcom and Credo, plus Nvidia CEO Jensen Huang's visit to Korea, are additional catalysts for the Korean semiconductor sector.
2. Prior-Week Forecast Review
| Prior Forecast | Actual Outcome | Verdict |
|---|---|---|
| Iran talks (5/31 target): deal → WTI $70–80s, inflation-relief rally / breakdown → WTI $110+ → S&P -8–12% | 60-day ceasefire MOU draft expectations drove WTI -9.57% ($87.36) and Brent -11.10%; S&P +1.43%, 9th consecutive record high. However, $70–80s target not reached and final signature not completed. | Partial Hit |
| Bank of Korea MPC (5/28) likely 8th consecutive hold; won weakness and foreign net selling as EWY (trail 13.55%) risk | 8th consecutive hold confirmed + Shin Hyun-song hawkish pivot (signaling hike within the year). However, EWY +13.07% and new entry condition met; won actually strengthened (-0.61%, ₩1,495). | Partial Hit |
| AI semiconductor SMH re-meeting entry condition to determine sector direction | Micron $1T and Dell AI server drove SMH to re-meet entry condition on 5/28; SMH +3.92%, XLK +5.89%, sector #1. | Hit |
| Iran breakdown → oil re-surge (25% probability): WTI $110+ → CPI 4%+ → risk-asset plunge | Opposite outcome — ceasefire progress drove WTI -9.57% and risk-asset rally. Risk scenario did not materialize. | Miss |
| Memorial Day thin liquidity + continued foreign selling → weak KOSPI flows | Despite 15 straight sessions of foreign net selling, domestic institutional and retail buying drove the KOSPI +8.01%. Flow weakness materialized in the KOSDAQ (-7.43%) instead. | Partial Hit |
3. Portfolio Drift & Risk
Weekly Portfolio Drift
If W21 was "Iran ceasefire progress → equities and bonds rally together, gold and gold miners liquidated," this week clarified that structure into a definitive "disinflationary risk-on" regime. The -9.57% oil plunge dragged down inflation expectations, pulling bond yields lower (10Y -2.41%, 30Y -1.38%) and improving growth-stock discount rates — while simultaneously delivering an asymmetric direct hit to the energy sector (XLE -5.38%). Gold (GLD +0.80%) and gold miners (GDX +5.26%), which had been weak the prior week, bounced on falling rates, signaling renewed inflows into safe-haven hedges.

Rebalancing Actions
Accumulate / New Entry
Entry condition flipped on 5/27. KOSPI +8.01% all-time high; Samsung Electronics ships world's first HBM4E 12-stack; SK Hynix crosses $1T market cap. Trail buffer recovers to 18.84%. The structural case is the spillover of the AI memory supercycle into Korea.
Accumulate / Re-Entry
Entry condition flipped on 5/28. Micron $1T and Dell AI server +757% triggered a sector re-rating. Trail buffer at 17.82%. Note that Qualcomm-style short-term profit-taking volatility coexists — enter at normal size and avoid chasing.
Exit / Entry Condition Lost
Entry condition flipped False on 5/27. Direct headwind from -9.57% oil decline; trail buffer compressed sharply from 11.16% to 8.70%. Iran ceasefire expectations are the core tailwind. Reduce exposure; monitor only for a snap-back if talks collapse.
Watch / New Entry but Thin Buffer
Entry condition flipped on 5/29 (trail recovered from 5.61% at week-open to 11.83%). Thin buffer just after entry means re-exit risk if volatility expands. Conservative sizing recommended (pair with XLK exposure).
Trim / Entry Condition Lost
Entry condition lost on 5/28; trail at 15.64%. K-shaped consumption dynamics and record-low Michigan consumer sentiment weigh. Monitor on further weakness.
Avoid — risk_flag=True Persists
Trail at -3.16% (negative). Gold edged up to $4,560 but entry condition not met. Unlike gold miners (GDX +5.26%), the ETF trend has not recovered. Avoid.
Hold
Entry conditions intact; trail buffers solid near 29%. Core positions with the thickest cushion despite 9 straight weeks of gains.
Hold / Thin Buffer
Entry conditions intact but CPER trail at 10.29% and DBB at 13.04% are thin. Avoid chasing.
Weekly Signal Events
- New entry conditions met: EWY (2026-05-27), SMH (2026-05-28), MSFT (2026-05-29)
- Entry conditions lost: XLE (2026-05-27), WMT (2026-05-28)
- Trail danger zone (< 5%): None. GLD remains risk_flag=True with trail at -3.16% (negative) — a condition persisting from the prior week, while already failing the entry condition.
- Thin trail buffer (< 15%): XLV 13.46%, XLE 8.70% 🔴, CPER 10.29%, DBB 13.04%, META 13.46%, MSFT 11.83%
Weekly Discussion Recap
Weekly Strategy Summary
With core positions (SPY, QQQ, XLK) and most large-caps maintaining entry conditions and thick trail buffers, the net signal direction for the week was improvement (3 new entries — EWY, SMH, MSFT — vs. 2 exits — XLE, WMT). That said, new entries are concentrated in AI memory and Korea momentum while exits are in energy and consumer, meaning sector bifurcation is now visible at the signal level as well. A VIX of 15.32 supports the risk-on backdrop, but the coexistence of internal weakness (new record highs with 10 sectors down, Russell -0.59%, KOSDAQ -7.43%) and multiple thin-buffer names (XLE 8.70%, GLD negative, MSFT 11.83%, CPER 10.29%) keeps this a "hold existing positions, but avoid chasing new entries" environment.

9. Next-Week Outlook
Key Scheduled Events
- 6/3 (Wed): South Korea local elections — record early-voting turnout of 23.51%. Policy direction on construction, real estate, and energy in focus.
- 6/5 (Fri, est.): U.S. May Jobs Report (NFP) — a beat would raise year-end rate-hike probability, pressuring bonds and growth stocks.
- Early June: Nvidia CEO Jensen Huang visits Korea — meetings with Samsung Electronics, SK Hynix, LG, and Naver on HBM and AI accelerator cooperation. Catalyst for Korean semiconductor stocks.
- Early June: Broadcom and Credo Technology earnings — confirmation of sustained AI infrastructure demand; a miss would risk a semiconductor correction.
- 6/10 (Wed): U.S. May CPI — whether the -9.57% oil decline feeds through. The most important data point ahead of Waller's first FOMC.
- 6/12 (Fri): SpaceX Nasdaq listing target — $1.75T valuation; ETF rebalancing flow implications.
- 6/16–17: FOMC meeting — Kevin Waller's first full chairmanship; rate hold vs. hike decision.
Key Watchpoints
- Iran ceasefire final signing — the week's biggest binary event: The 60-day MOU draft was agreed but Trump has not signed; Iran continues missile strikes toward Kuwait and drone provocations near the Strait of Hormuz. A signed deal means further WTI decline + inflation relief rally broadening; a breakdown means WTI re-enters $100+ and delivers a -5–8% counter-shock to the S&P.
- 6/10 CPI energy base effect vs. 6/17 Waller's first FOMC: If oil's plunge feeds through to May CPI, rate-hike fears ease. However, the stickiness of shelter inflation (+0.6%) and core PCE at 3.3% is the wildcard. A CPI beat would send the probability of a hike at Waller's first FOMC sharply above 15%.
- Whether the narrow rally broadens: The bifurcation — new record highs with 10 sectors down, Russell -0.59%, KOSDAQ -7.43% — is the key tell. If oil's decline spills over into consumer and financial stocks, the bull market extends (Jim Cramer's "broadening" scenario). If AI profit-taking takes over, a dot-com-style correction looms (BTIG and Burry warnings).
Risk Factors
- Iran ceasefire collapse → oil re-surge (30% probability): WTI re-enters $110–125 → May/June CPI breaks 4%+ → 30-year yield re-breaks 5.2–5.5%; risk assets -5–8%.
- AI demand peak / guidance miss (20% probability): Broadcom or Credo earnings fall short or Big Tech signals capex pullback in early June → SMH -10–15%, Nasdaq -2–3%. SMH (trail 17.82%) and MSFT (11.83%) with thin buffers are vulnerable to re-exit.
- KOSDAQ weakness and continued foreign outflows: KOSDAQ -7.43% weekly plunge; foreign net selling for 15 straight sessions. If the KOSPI mega-cap concentration reaches its limit, EWY (new entry, trail 18.84%) faces volatility exposure.
- Bank of Korea July hike materializing → household debt and real estate stress: Governor Shin officially signals hike within the year (dot plot: 3.00% as mode); non-performing loans at ₩17.7T (highest since 2019). If the hike becomes reality, real estate and domestic consumer stocks face pressure.
This Week's Q&A
- In the last week of May, U.S. equities hit all-time highs for the ninth straight week, yet the bond market was simultaneously warning of a year-end rate hike. Two markets looking at the same economy and signaling the exact opposite — which one was right?
- The KOSPI surged +8% that week to an all-time high while the KOSDAQ fell -7%. Same country, same week — why did they go in opposite directions, and which side is my Korea fund exposed to?
- The strategy signals flipped to 'buy' on Korea and semiconductors and 'sell' on energy that week. But the Korea ETF had already surged 13% before the buy signal appeared. Is it still safe to follow it?
