Important notice: U.S. markets are CLOSED tomorrow, Friday June 19, 2026, for Juneteenth National Independence Day. NYSE and Nasdaq do not open. Bonds, DTC settlement, and banking rails are all paused. The data below covers Thursday June 18 — the final trading session of the week and the session you want to understand before markets reopen on Monday, June 22.
And what a session it was. Chip stocks dominated in a way not seen since the AI boom’s peak. Intel hit a new all-time high of $133.82. Micron surged 8% ahead of its pivotal earnings next week. QuantumScape jumped nearly 16% on a Honda partnership. The S&P 500 added 1% to close at 7,490.21. And oil fell another 2.7% to $73.94/barrel as Trump formally signed the Iran peace MOU.

🟢 TOP STOCK GAINERS TODAY — Thursday, June 18, 2026
1. INTC — Intel Corporation | +9.67% to $132.81 | New All-Time High: $133.82
Intel was Thursday’s undisputed headline winner — and it was not close. After Trump posted on Truth Social that Apple had agreed to design and build chips domestically with Intel, INTC leapt as much as 10.5% to $133.82 shortly after the opening bell — breaching its previous all-time high of $132.75 set on May 11, 2026.
| Metric | Value |
|---|---|
| Thursday Close | $132.81 |
| Intraday High (New ATH) | $133.82 |
| Prior Close (Wednesday) | ~$120.82 |
| 52-Week Low | $18.97 |
| 52-Week High (Set Today) | $133.82 |
| YTD Return | +490–600%+ from January lows |
| Key Catalyst | Apple U.S. chip manufacturing deal |
| 18A-P News (June 17) | Risk production entered |
- The Apple deal is a landmark: Apple historically relied entirely on TSMC for its custom silicon (A/M-series chips). A domestic Intel foundry partnership represents a geopolitical shift of generational significance — and validates Intel Foundry Services (IFS) as a viable commercial-scale alternative to Asian fabs
- Bernstein raised PT to $100 (from $65) this week — but with INTC closing at $132.81, the stock is trading well ahead of even the most constructive analyst models
- AMD also rose 4%+ Thursday; Broadcom gained 4%+; Nvidia added 2% — the Apple/Intel news created a semiconductor sector-wide rerating
2. QS — QuantumScape Corporation | +15.87% to $8.00
QuantumScape surged nearly 16% Thursday, cementing a remarkable week. The catalyst: the company announced a major joint research partnership with Honda for solid-state battery co-development — Honda cited “rigorous evaluations” before committing to the multi-year deal.
| Metric | Value |
|---|---|
| Thursday Close | $8.00 |
| Wednesday Close | ~$6.90 |
| QS June 18 Gain | +15.87% |
| 52-Week Low | $4.16 |
| 52-Week High | $19.07 |
| Honda Deal | Multi-year solid-state co-development |
| Q1 Customer Billings | $11M (growing) |
| FY2026 EBITDA Guidance | -$250M to -$275M (reaffirmed) |
- QS’s 16% single-day gain on top of a strong week represents a genuine sentiment shift: OEM validation from Honda — the world’s 7th largest automaker — signals that QuantumScape’s technology has cleared third-party due diligence
- The expansion into aerospace, defense, and AI data center backup power is the next narrative catalyst that could push QS above $10
3. MU — Micron Technology | +8% (June 18)
Micron was the semiconductor sector’s most anticipated performer Thursday — its Q3 FY2026 earnings are due next week — and the combination of AI memory demand optimism and INTC’s Apple deal creating sector enthusiasm pushed MU up 8%.
| Metric | Value |
|---|---|
| Thursday Gain | +8% |
| Q3 FY2026 Earnings | Due June 24, 2026 |
| AI Memory (HBM3E) | Core demand driver; NVDA allocation |
| 52-Week Range | ~$60 – $145 |
| Analyst Consensus | Buy |
| Implied June 24 EPS | Beat expectations (market pricing) |
- MU at +8% pre-earnings is the market pricing in a beat. The AI memory buildout — driven by HBM3E demand from Nvidia’s GB200/Blackwell systems — gives Micron significant pricing power going into Q3
- Monday risk: If MU rallies 8% Thursday and then misses on June 24, the gap-down after earnings will be severe. Pre-earnings run-ups of this magnitude are a double-edged sword
4. Dow Jones Gainers — CAT, HD, MMM
| Ticker | Company | Thursday Gain | Catalyst |
|---|---|---|---|
| CAT | Caterpillar | +3.67% | Iran peace deal = infrastructure rebuild demand |
| HD | Home Depot | +2.83% | Iran deal + oil lower = consumer spending relief |
| MMM | 3M | +1.68% | Dow positive breadth; industrial recovery |
Caterpillar’s 3.67% gain is thematically significant: a peace deal in Iran means infrastructure reconstruction spending in the region, and Caterpillar’s construction and mining equipment is in direct demand for post-conflict rebuilding. That forward-looking demand signal explains why CAT led the Dow Thursday.
5. NVDA, AMD, AVGO — The AI Chip Cluster
| Ticker | Company | Thursday Gain | Context |
|---|---|---|---|
| NVDA | Nvidia | +2% | Recovered Wednesday’s FOMC decline |
| AMD | AMD | +4%+ | CPU revival narrative (Bernstein) |
| AVGO | Broadcom | +4%+ | AI ASIC demand; sector momentum |
Bernstein published a note Thursday calling AI-driven CPU demand a revival across INTC, AMD, and ARM simultaneously — the shift from pure chatbot AI to agentic AI significantly increases CPU workloads per inference request. That rising-tide thesis lifted the entire chip complex.
6. Airlines — The Oil Peace Dividend
WTI crude fell to $73.94 Thursday — its lowest level since before the Iran war began in late February. Airlines were among the session’s most direct beneficiaries:
- AAL (American Airlines): +5–6% (est.)
- DAL (Delta Air Lines): +4–5% (est.)
- UAL (United Airlines): +4–5% (est.)
WTI at $73.94 — down from $113+ at the war’s peak — translates to billions in annualized fuel cost savings for U.S. carriers. The Iran MOU signing Thursday evening cements the trajectory: if the Hormuz formal reopening proceeds as scheduled (30 days from signing), WTI could test $68–$70 by mid-July, further accelerating airline margin expansion.
7. VIX at 16.96 — The Market’s Exhale
The CBOE Volatility Index fell 8.02% to 16.96 Thursday. That is the market pricing out fear. A VIX at 17 heading into a 3-day Juneteenth weekend — after a Fed decision, an oil crash, and an Intel all-time high — is a statement: investors are not afraid of what happens while markets are closed. That is a constructive setup for Monday June 22’s open.
What Thursday’s Gainers Tell You About Monday June 22
- INTC at $132.81 heading into a long weekend where the Apple deal has had 3 days to digest = either confirmation or profit-taking at the open Monday
- QS at $8.00 with Honda deal momentum = watch for further analyst initiations or target increases over the weekend
- MU +8% pre-earnings = June 24 earnings are the make-or-break event; any miss after this run creates a very sharp correction
- VIX at 16.96 + Russell 2000 +1.41% = broad market risk appetite intact entering the long weekend
The last trade of the week was placed at 4:00 p.m. ET Thursday. The next one is at 9:30 a.m. ET Monday, June 22 — with five new Nasdaq-100 members joining at the bell and the Iran signing in Geneva already in the history books.
