1. Weekly Summary

The Upside

The week's primary upside catalyst was progress in U.S.-Iran peace negotiations. After Secretary of State Rubio declared a deal was "in sight," WTI crude plunged -8.37% on the week to $96.60, pulling inflation expectations lower and dragging the 10-year yield from 4.59% to 4.56% and the 30-year from 5.13% to 5.06%, sparking a broad risk-asset rally. Nvidia's Q1 revenue of $81.6B—beating consensus of $79.2B and rising +85% YoY—delivered an earnings surprise that reaffirmed the durability of the AI infrastructure investment cycle and lifted semiconductors (SMH +3.59%). A last-minute labor agreement at Samsung Electronics averted a general strike on May 20, propelling the KOSPI to its largest-ever single-day gain (+8.42%) on May 21 and a weekly close of +4.73%. The Dow Jones hit a record 50,579; the S&P 500 extended its winning streak to eight consecutive weeks; and the VIX fell from 18.43 to 16.70 (-9.39%), signaling a normalization of fear.

The Friction

Beneath the rally, structural inflation remained unresolved. April CPI at 3.8% (highest since May 2023), core PCE accelerating to a 3-month annualized rate of 4.4%, and the 30-year Treasury at 5.06% (highest since 2007) continued to pressure the Fed regardless of any deal outcome. The swearing-in of Kevin Warsh as the new Fed Chair (5/22) and hawkish April FOMC minutes drove markets to price the probability of a 2026 rate cut below 3%, while the odds of a December hike rose to 39%. University of Michigan consumer sentiment at 44.8 (all-time low) and gasoline at $4.55 deepened K-shaped consumer divergence, and Walmart fell -8.51% on the week, breaking below its 100-day moving average. China (KWEB -4.47%, Hang Seng -1.37%), precious metals (GLD -0.83%, GDX -2.67%), and crypto (BTC -0.58%, BITO -4.17%) were left out of the rally; even Nvidia fell -4.43% on the week as post-earnings "expectation exhaustion" set in.

Outlook

The week's pivotal binary is the May 31 Iran deal deadline (current probability: 35.5%). A deal would send WTI further into the $70–80 range, extending the disinflation rally; a breakdown would push WTI back above $110, triggering an estimated -8–12% shock to the S&P 500. The Memorial Day holiday on May 25 will leave a liquidity vacuum, with weekend negotiation headlines determining the direction of Tuesday's open gap. The Bank of Korea MPC meeting (May 28, Governor Shin Hyun-song's inaugural meeting, with an eighth consecutive hold at 2.50% the base case) and the first FOMC under Warsh on June 16–17 are sequential inflection points. The stretched valuations of AI semiconductors (SOX YTD +65%, Micron +124%) and the supply/demand impact of the SpaceX IPO (targeting June 12) are additional variables to watch.

2. Last Week's Forecast Review

Prior-Week ForecastActual OutcomeVerdict
Nvidia beats (5/20) → SMH trail recovery + semiconductor sector reboundRevenue $81.6B surprise (consensus $79.2B). SMH +3.59%, trail recovered 13.98→18.94Hit
PCE/inflation above expectations → 30Y above 5.2% → risk-off / below → 10Y returns to 4.4%Rates eased (10Y 4.56%, 30Y 5.06%) and risk-on resumed, but the catalyst was Iran negotiations, not PCE. 10Y return to 4.4% fell short.Partial Hit
Samsung Electronics strike materializes → EWY trail approaches 10% / Bank of Korea cut → KRW strengthensStrike called off 5/20 → KOSPI +8.42%, EWY +1.77% (trail 13.55%). Bank of Korea meeting rescheduled to 5/28; no cut occurred.Miss
Inflation persists → 30Y above 5.3% → S&P retests 7,00030Y fell to 5.06%; S&P rose to 7,473 for eighth consecutive week (risk did not materialize)Miss
Iran Strait of Hormuz blockade escalation → WTI $120+ → stagflationNegotiations advanced; WTI fell -8.37% to $96.60—the opposite directionMiss
Foreign investor outflows accelerate → KOSPI retests 7,000Foreign net selling continued (₩1.9T+/week), but retail and institutional buying defended KOSPI, up +4.73%Miss
The only prior-week forecast that came through was the semiconductor rebound tied to Nvidia's strong earnings. The bearish scenario built around inflation, rates, Iran, and foreign outflows largely missed, because an unexpected easing catalyst—the Iran negotiation breakthrough—simultaneously pulled down oil prices and interest rates, neutralizing the macro headwinds en masse. Overweighting macro risks while underestimating the potential for a policy/geopolitical reversal was the central forecasting error of the prior week.

3. Portfolio Drift & Risk

Weekly Portfolio Drift

If last week (W20) was stagflationary—energy the lone gainer while all other asset classes fell together—this week was the mirror image: equities and bonds rallied in tandem while volatility plunged. Iran negotiation progress simultaneously pulled oil (-8.37%) and rates lower, flipping the regime to "disinflation → joint strength in risk assets and bonds." The exception was gold (-0.83%) and gold miners (GDX -2.67%), which fell despite lower yields as safe-haven demand evaporated—a sign that risk-off hedges were being rapidly unwound.

Rebalancing Actions

XLV

Accumulate / New Entry

Entry condition triggered on 5/19. Benefits from defensive rotation amid inflation and rate concerns. However, trail buffer of 13.72% is thin—enter at standard size but avoid chasing.

+3.30%
TSLA

Watch / New Entry but Thin Buffer

Entry condition triggered on 5/22 (trail 14.65→15.40%). Buffer at 15% immediately post-entry makes a re-exit possible if volatility spikes. Conservative sizing advised.

+0.89%
BOTZ

Trim / Entry Exit

Entry condition exited on 5/19 (True→False). Robotics/AI theme momentum fading. Hold off on new additions; manage existing holdings within the 16.6% trail.

+0.15%
SMH

Hold / Trend Not Met but Buffer Recovering

Entry condition still unmet, but trail recovered from 13.98% to 18.94%. Nvidia earnings surprise lifted the sector. Wait for trend re-confirmation before adding.

+3.59%
XLE

Hold / Thin Buffer

Entry condition maintained but trail at 13.74% is thin. Held flat despite oil's -8.37% plunge. Holding due to potential sharp rebound on Iran breakdown.

+0.08%
GLD

Avoid — risk_flag=True Persists

Trail at -3.81% (negative) persists. Entry condition unmet as safe-haven demand weakens despite lower rates. Avoid.

-0.83%
WMT

Hold / Sharp Buffer Decline

Entry condition maintained but trail plunged from 27.98% to 18.98%. K-shaped consumption concerns and a break of the 100-day MA. Reassess if further weakness emerges.

-8.51%
SPY / QQQ / XLK

Hold

Entry condition maintained; trail steady in the 29% range. Eight consecutive weeks of gains have not eroded the buffer—maintain core positions.

+0.9~2.3%

Weekly Signal Events

  • New entry conditions triggered: XLV (2026-05-19), TSLA (2026-05-22)
  • Entry conditions exited: BOTZ (2026-05-19). Additionally, EWY, SMH, and TSLA began the week with their prior Friday (5/15) bullish signals already flipped to unmet at Monday's open.
  • Trail danger zone (< 5%): None. GLD's risk_flag=True has kept trail at -3.81% (negative) since last week, but it already fails the entry condition.
  • Thin trail buffer (< 15%): EWY 13.55%, XLV 13.72%, XLE 13.74%, CPER 10.44%, DBB 12.77%, META 10.52%, MSFT 6.07% 🔴 (lowest)

Weekly Discussion Review

No signal discussions this week

Weekly Strategy Summary

With core positions (SPY, QQQ, XLK) and most large-cap holdings maintaining entry conditions and trail buffers recovering, the net directional signal for the week was a modest improvement (2 new entries—XLV, TSLA—vs. 1 exit—BOTZ). Iran negotiation progress and the Nvidia earnings surprise restored the buffer for SMH and broader semiconductors, while the VIX normalizing to 16.7 reinforced the risk-on regime. However, trail buffers for several new and existing entries (XLV, XLE, TSLA, CPER, DBB) remain below 15%, keeping the market in a "hold existing positions, but avoid chasing" posture. MSFT (6.07%) and META (10.52%) are in unmet territory with thin buffers—avoidance is the priority.

Sentiment opened with cautious bullishness, turned bearish mid-week on NVDA earnings anticipation, Trump insider-trading concerns, and rate anxiety, then pivoted bullish Thursday-Friday on the Nvidia surprise, before retreating to neutral-to-bearish caution over the weekend amid SpaceX IPO overheating fears and the AI capex bubble debate. Sentiment lagged the actual price rally throughout; even within the bull market, persistent high-valuation and bubble worries never fully dissipated—an "anxious bull market" psychology that lingered to the end.

9. Next-Week Outlook

Upcoming Key Events

  • 5/25 (Mon): U.S. Memorial Day holiday — reduced liquidity; weekend Iran talks determine Tuesday's open gap
  • 5/27 (Tue): Samsung Electronics union wage vote results / U.S. markets reopen
  • 5/28 (Wed): Bank of Korea Monetary Policy Board meeting — Governor Shin Hyun-song's first meeting; eighth consecutive hold at 2.50% is the base case
  • 5/31 (Sun): Iran-U.S. peace deal target date — current deal probability: 35.5%
  • 6/10 (Wed): U.S. May CPI release — will energy price declines be reflected?
  • 6/12 (Fri): SpaceX Nasdaq listing target — largest IPO in U.S. history; ETF rebalancing flow impact
  • 6/16–17: FOMC regular meeting — Kevin Warsh's first official policy decision

Key Watch Points

  1. Iran Negotiations (5/31 target) — Near-Term Binary Event: A deal sends WTI into the $70–80 range → CPI slowdown → rate-hike fears ease → additional risk-asset rally. A breakdown pushes WTI back above $110, inflicting an estimated -8–12% reverse shock on the S&P 500.
  2. Bank of Korea MPC Meeting (5/28) + KRW Direction: An eighth consecutive hold is the base case, but forward guidance is the wildcard. KRW weakness (USD/KRW 1,504–1,519) and continued foreign net selling (₩1.9T+/week) are the core risks for EWY (trail 13.55%) positions.
  3. AI Semiconductors — Supercycle Continuation vs. Overbought Profit-Taking: Despite SOX YTD +65% and Micron +124%, Nvidia fell -4.43% on record earnings as "expectation exhaustion" set in. Whether SMH regains its trend entry condition (entry_ok) will determine the sector's direction.

Risk Factors

  1. Iran Negotiations Break Down → Oil Price Spike (Probability: 25%): WTI back above $110 → May CPI above 4% → second inflation shock → 30Y above 5.3%, sharp risk-asset sell-off.
  2. Warsh June FOMC Hawkish Surprise (Probability: 15%): A rate hike signal would send growth stocks down 10–15% with severe impact on REITs, utilities, and long-duration bonds. Unpriced risk relative to the ~15% already reflected in futures.
  3. Memorial Day Low Liquidity + Continued Korean Foreign Outflows: Volume drop around the holiday amplifies volatility. If cumulative foreign net selling converges with margin call selling (exceeding ₩100B), the KOSPI's supply/demand vulnerability will be exposed.
