Thursday delivered one of the most dramatic single-session reversals of 2026. One week after Chang Xin Memory Technologies’ 466% Shanghai IPO debut triggered a $1 trillion wipeout in semiconductor stocks, the exact opposite happened. Microsoft surged 16%, adding roughly $450 billion to its market value — the single largest one-day market cap gain by any stock in history. SanDisk rebounded 24%. Samsung warned the memory crunch extends into 2028. And Starbucks, Chipotle, and Coursera all beat and raised guidance.

The Nasdaq 100 advanced 3.13%–3.4% — its best session since April 2025. The Nasdaq Composite finished 2.8% higher at 25,122.18. The S&P 500 gained 1.49%. The Dow climbed 1.09%. Here are the 10 stocks that led the charge.

Session Summary — July 30, 2026:

🚀 #1 — Microsoft (MSFT) | +14.28% to +16% | The Single Largest Single-Day Market Cap Gain in History

This is not a superlative to throw around casually. Microsoft surged 16%, adding roughly $450 billion to its market value — the most ever added by any stock in a single trading session. The previous record (held by Nvidia) just fell.

Q4 FY2026 Results — Full Data:

Why Microsoft Was the Perfect Antidote to the AI Capex Fear:

The market has been living in dread of one specific scenario: hyperscalers raising AI capex indefinitely with no corresponding revenue proof. Alphabet raised its capex and was hammered. Meta raised capex again — the market punished it 9–10%. Microsoft’s results were the first clean counter-narrative: 43% cloud revenue growth (the most since 2022) combined with capex guidance that did not outpace expectations.

“Microsoft’s results suggest concerns about slowing growth may have been overstated,” said Stephen Evans, CIO at Pave Finance. It was also described as the “tale of two AI investment strategies” — Microsoft increasing profits while spending heavily, versus Meta allowing AI costs to destroy bottom-line results.

The Copilot Signal: Azure’s 43% growth directly reflects enterprise AI adoption — companies paying for Copilot, Azure OpenAI Service, and AI-powered Microsoft 365. This is the revenue proof that the market had been demanding from the AI infrastructure buildout, and Microsoft delivered it in the cleanest possible form.

What Comes Next: Microsoft also signalled potential 2027 spending expansion — but framed around growth that justifies that spending. Amazon reports after the bell Thursday with “booming” cloud growth previewed by CNBC — suggesting Microsoft’s bullish session may extend through Friday.

🚀 #2 — SanDisk (SNDK) | +23.9% | Samsung’s Warning Flips the Memory Narrative

SanDisk surged 23.9% — its largest single-session gain in 2026 — driven by one of the most counterintuitive bullish catalysts of the earnings season.

The Samsung Warning That Saved Memory Stocks:

Samsung, in its Q2 2026 earnings call, warned that the memory chip shortage could extend into 2028 — far longer than any analyst had previously modelled. Qualcomm’s CEO separately called the memory chip price increases “very dramatic” on its own earnings call.

Why “Worse For Longer” Is Bullish For Memory Stocks:

This sounds paradoxical until you understand the memory economics: SanDisk is a memory chip producer, not a consumer. Higher memory prices = higher revenue per unit. Samsung’s warning that supply constraints persist through 2028 means:

• SanDisk’s pricing power is structural, not cyclical
• The feared CXMT/YMTC Chinese competitive threat is years away from affecting pricing
• The “memory crunch” that has forced Apple, Microsoft, and others to raise hardware prices benefits producers like SanDisk

The stock had been battered in the prior week — falling 11–14% on CXMT’s Shanghai IPO debut. Thursday’s 24% recovery partially reverses that decline, and Samsung’s 2028 supply shortage warning changes the medium-term thesis entirely.

Key Data:

🚀 #3 — Lam Research (LRCX) | +18.4% | Chip Equipment Leader Roars Back

Lam Research gained 18.4% — one of the largest single-day gains in the chip equipment sector in recent memory — combining an earnings beat with the broader chip sector recovery narrative.

Why Lam Specifically:

Lam Research makes the etch and deposition equipment used to manufacture DRAM and NAND flash. When Samsung warns the memory shortage extends to 2028, it simultaneously signals that memory manufacturers are not sitting still — they are investing in new capacity. Lam supplies the equipment for that capacity expansion. The logic chain: memory shortage → memory producers expand capacity → memory producers buy Lam equipment → Lam’s forward order book grows.

The earnings beat validated that the order book is indeed strong. Management commentary on H2 2026 equipment delivery timelines — which were described as healthy — confirmed the demand signal is real.

🚀 #4 — Micron Technology (MU) | +17.0% | Memory Recovery’s Most Direct Play

Micron surged 17% — recovering from the brutal CXMT-driven selloff of the prior sessions. The Samsung 2028 memory crunch warning directly benefits Micron’s pricing outlook across both DRAM and NAND segments.

Key Context:

Micron had reported extraordinary Q3 FY2026 fundamentals just weeks ago — $41.46B in revenue (+345.7% YoY) and Q4 guidance of $50B. The CXMT selloff had pushed the stock down ~33% from its 2026 peak despite those numbers. Thursday’s 17% recovery represents the market recognising that the near-term CXMT competitive threat was priced in too aggressively — Samsung’s 2028 supply warning gives Micron multiple years of pricing power runway.

🚀 #5 — SK Hynix (SKHY) | +15% | Wednesday’s Loser Becomes Thursday’s Winner

SK Hynix rose 15% — a complete reversal from Wednesday’s session, when the stock fell sharply after Q2 results missed elevated expectations. Samsung’s memory crunch warning changes the HBM pricing outlook for SK Hynix — the world’s dominant HBM producer — materially. If memory supply constraints persist to 2028, SK Hynix’s premium HBM margins are protected for the foreseeable future.

🚀 #6 — Applied Materials (AMAT) | +13.8% | Semiconductor Equipment Sector Surges

Applied Materials climbed 13.8% — the broadest semiconductor equipment company in the cohort, making the deposition, etching, and inspection tools for every major chip type. As the sector recovery broadened from memory to logic chips, Applied Materials benefited from the same tailwinds lifting Lam Research.

AMAT’s exposure to both memory and logic chip manufacturing makes it the most diversified semiconductor equipment play — and on a day when both segments surged, the breadth of its recovery reflects that diversification.

🚀 #7 — Chipotle Mexican Grill (CMG) | +13.0% | Fruity Refreshers and Honey Chipotle Chicken Save the Quarter

Chipotle rose 13.0% after raising full-year guidance following a stronger-than-expected Q3 2026. The driver? New menu items — specifically trendy limited-time offerings and a revamped loyalty programme.

Bloomberg noted that both Chipotle and Starbucks raised guidance “after stronger-than-expected quarters, with sales bolstered by trendy new menu items and revamped loyalty programs.” In a week dominated by AI capex debates and memory chip geopolitics, Chipotle’s burritos outperformed every management narrative in terms of clarity: customers ordered more, paid more per visit, and returned more often.

Why This Is More Than a Beat: Chipotle has used comparable sales acceleration as proof that its loyalty app — now with more than 40 million members — drives repeat visit frequency measurably. Management’s decision to raise guidance tells investors that H2 2026 is expected to match or accelerate Q3’s momentum.

🚀 #8 — Intel (INTC) | +12.7% | Turnaround Validation in the Chip Rebound

Intel rose 12.7% — benefiting from the broader chip sector rebound without any specific Intel-negative catalysts for the day. The chip sector recovery that began with Microsoft’s results and was amplified by Samsung’s memory supply warning lifted Intel on broad sentiment.

Intel’s 18A foundry node remains the most closely watched technical milestone in its multi-year turnaround. Any positive commentary from semiconductor customers about early production yields on 18A would be the specific catalyst that takes Intel from “sector sympathy” gains to “fundamental re-rating” gains.

🚀 #9 — Starbucks (SBUX) | Raised Guidance | CEO Niccol’s Turnaround Gets Its First Win

Starbucks raised its guidance after a stronger-than-expected Q3 FY2026, validating CEO Brian Niccol’s “Back to Starbucks” operational restructuring in the most direct way possible: comparable store sales turned positive.

The Three Numbers That Moved the Stock:

1. US comparable store sales: Turned positive after consecutive quarters of decline — the single most-watched turnaround metric
2. China comparable store sales: Showed improvement versus the chronic weakness in prior quarters
3. Full-year guidance raise: Management’s willingness to raise means confidence in the improvement is operational, not transient

Bloomberg described the underlying driver succinctly: consumers’ reluctance to spend was “no match for fruity refreshers and chipotle honey chicken burritos” — a line that captures the new menu strategy’s effectiveness in a single sentence.

🚀 #10 — Coursera (COUR) | Earnings Move | AI-Powered Education at a Micro-Cap Valuation

Coursera was among the notable movers after reporting earnings Thursday, with the online learning platform’s results highlighting an interesting intersection with the day’s dominant theme.

Key Data:

Microsoft’s AI education partnership with Coursera — which enables employees to earn verified credentials through the platform — has driven a meaningful uptick in enterprise subscription revenue. With Microsoft’s Azure 43% growth and Copilot enterprise adoption both accelerating, the enterprise learning spend that funds Coursera subscriptions is directly correlated.

The volume of 9.58 million shares (2.7x average) on earnings day confirms institutional and retail interest alike. The stock is trading well below its 52-week high of $13.56 — creating a valuation gap that a sustained earnings recovery could begin to close.

Also Gaining: The Rivian and Caterpillar Stories

Rivian Automotive (RIVN) rose nearly 2% after the electric vehicle maker reduced its 2026 spending plans and narrowed its previously forecasted losses — a classic “show us you’re being disciplined” response to cost-cutting announcements in a rate-sensitive market.

Caterpillar (CAT) gained 3.26% — the third-best performer in the Dow on Thursday — validating the infrastructure and industrial equipment demand story that has been one of the quieter outperformers of H1 2026.
