Today's session was powered by two simultaneous mega-catalysts: Trump's Apple-Intel domestic chip manufacturing push and the US-Iran MOU that eased energy supply fears. Both themes point in the same direction — lower inflation, higher tech multiples — which is why markets absorbed the prior day's hawkish FOMC signal in a single session. However, the sharp USD/KRW surge of +24 won to 1,535.19 is a reminder that the Fed's rate-hike signal is still applying meaningful pressure on emerging market currencies. The key inflection point is June 24, when Micron earnings and Qualcomm's Investor Day will determine whether the semiconductor rally has durable legs.

🧭 Sector Performance
🇰🇷 Korean Investor Perspective
QQQ tracked Nasdaq's +1.91% gain, but the sharp USD/KRW jump of +24 won to 1,535.19 nearly erased real returns for unhedged Korean investors converting back to KRW. For those directly holding MU, INTC, or QCOM, it was an exceptionally strong day in dollar terms. However, SPCX holders face a -18% drawdown from the June 16 all-time high after two consecutive down sessions. TQQQ (3x Nasdaq) holders theoretically gained ~+5.7%, but currency deterioration could cut that to under +3% in won terms. Micron earnings and Qualcomm's Investor Day on June 24 are the pivotal near-term events for semiconductor-focused Korean retail investors.
📊 Market Overview
U.S. equities rebounded sharply on Thursday, June 18, 2026, recovering from the prior session's FOMC-driven selloff. The S&P 500 closed at 7,500.58 (+1.08%, +80.48 pts), reclaiming the 7,500 level, while the Nasdaq surged 26,517.93 (+1.91%, +496.27 pts) as tech buy flows returned forcefully. The Dow Jones edged up to 51,564.70 (+0.14%, +72.15 pts), with gains capped by weakness in energy and financials, which carry significant weight in the index.
The primary catalyst was President Trump's announcement of an Apple-Intel domestic chip manufacturing partnership, igniting a broad-based semiconductor rally. Intel (INTC) surged +10.64%, spreading momentum to Micron (MU +8.70%), Qualcomm (QCOM +6.17%), ARM (+4.91%), and AMD (+4.86%). Conversely, U.S.-Iran MOU signing confirmed the reopening of the Strait of Hormuz, sending oil prices sharply lower and dragging energy stocks — COP (-3.12%) and CVX (-2.22%) — into negative territory.
🔑 Key Issues
1. Trump Announces Apple-Intel Chip Partnership — INTC +10.64%
President Trump announced via social media that Apple has agreed to design and manufacture chips with Intel in the United States. Intel's Oregon, Arizona, and Ohio fabs are expected to produce chips for iPhones and Macs. The U.S. government already holds a 10% stake in Intel (acquired August 2025), amplifying the strategic significance of this deal. Intel closed at $133.99 (+10.64%) on the news. However, Apple CEO Tim Cook signaled potential iPhone price increases, limiting Apple's own stock reaction.
2. Micron Crosses $1 Trillion Market Cap — MU +8.70%
Micron (MU) surged +8.70% to $1,133.99, crossing the $1 trillion market cap milestone. A wave of bullish analyst upgrades, including Wells Fargo raising its QCOM price target from $160 to $230, and anticipation ahead of MU's fiscal Q3 earnings on June 24 accelerated buying. Of 30 tracking institutions, 27 currently hold Buy ratings on Micron. Qualcomm (QCOM) also jumped +6.17% on Wells Fargo's upgrade and excitement heading into its June 24 Investor Day.
3. US-Iran MOU Signed — Oil Prices Plunge, Energy Stocks Hit
The United States and Iran formally signed a 14-point memorandum of understanding in France, confirming the reopening of the Strait of Hormuz. The deal would resume access to Iran's oil markets and unlock over $100 billion in frozen assets. WTI crude fell to $75.83 (-1.25%), while COP (-3.12%), CVX (-2.22%), and other energy names sold off broadly. Stock markets, however, welcomed the inflationary relief as a positive.
4. Nasdaq Rebounds From FOMC Shock
The prior day's FOMC meeting left rates unchanged but signaled possible rate hikes later in 2026, triggering a selloff. On June 18, the sharp drop in oil prices eased inflation concerns, fueling a tech-led recovery. The Nasdaq led all major indices at +1.91%, and the Russell 2000 also gained +2.02%, reflecting broad-based risk appetite.
5. SPCX (SpaceX) Falls for Second Consecutive Day — $185.00 (-3.56%)
SpaceX (SPCX) fell another -3.56% to $185.00, now down approximately 18% from its June 16 all-time high of $225.64. Post-IPO momentum has faded rapidly as profit-taking intensifies. Reports of a potential $20B+ bond issuance amplified leverage concerns, adding additional selling pressure. The day's trading range was $172.11–$192.00. SPCX remains 37% above its June 12 IPO price of $135, but near-term momentum has clearly reversed.

🚀 SPCX (SpaceX) Update
SpaceX (SPCX) closed at $185.00 (-3.56%) on June 18, extending its losing streak to two consecutive sessions. The stock has shed roughly 18% from its June 16 all-time high of $225.64, signaling that post-IPO euphoria has rapidly faded. Reports of bankers exploring a $20B+ bond deal for SpaceX amplified concerns about the company's debt load. Intraday range was $172.11–$192.00, reflecting persistent selling pressure. SPCX still trades at a 37% premium to its June 12 IPO price ($135), but the short-term momentum cycle has clearly reversed.
⚠️ Investor Caution
The Fed's hawkish posture and dollar strength coexist with today's equity recovery, and the USD/KRW jump of +24 won to 1,535.19 is a stark reminder of FX risk for international investors. Despite the US-Iran MOU, final implementation faces significant uncertainty, warranting caution on energy names. Investors should prepare for elevated volatility ahead of Micron earnings and Qualcomm's Investor Day, both scheduled for June 24.
