Executive Summary
AI’s Memory Shock: Micron (MU) delivered a blowout quarter and reinforced the strength of AI-driven memory demand, but the same surge in memory prices pressured Apple (AAPL), Microsoft (MSFT), Amazon (AMZN), and other mega-cap technology names.
Crude Cracks, Rotation Rips: Progress around U.S.-Iran negotiations and improving traffic through the Strait of Hormuz helped push crude oil lower, supporting airlines, homebuilders, industrials, and other rate- and energy-sensitive areas of the market.
Data Boxes the Fed: First-quarter GDP was revised higher to 2.1%, May income and spending both rose 0.7%, and core capital goods orders rebounded 1.6%, keeping the soft-landing narrative alive but complicating the inflation and interest-rate outlook.
AI’s Memory Shock
The artificial intelligence trade remained the market’s dominant story this week, but the tone changed noticeably. Instead of a simple “AI winners go up” environment, investors were forced to sort through a more complicated question: who benefits from AI scarcity, and who pays for it? The pressure began early in the week as mega-cap technology stocks weakened. Alphabet (GOOGL) fell sharply after John Jumper, a senior Google DeepMind researcher and co-creator of AlphaFold, left for Anthropic. That added to concerns that the AI talent war is intensifying just as hyperscalers are already spending aggressively on data centers, chips, and infrastructure.
The bigger shock came from semiconductors. On Tuesday, the Philadelphia Semiconductor Index fell 7.9%, with weakness spilling over from South Korea after steep losses in Samsung Electronics (SSNLF) and SK Hynix (HXSCL). SK Hynix had mentioned it was slowing High-Bandwidth Memory production to focus on DRAM which caused prediction markets to price chips lower. U.S. memory-related names were hit hard, including Micron and Sandisk, while equipment and analog names such as Lam Research (LRCX) and onsemi (ON) also sold off. The selloff did not look like a collapse in AI demand. It looked more like investors questioning whether expectations had become too crowded after a huge run in chip stocks.
Micron then complicated the story in the opposite direction. The company reported a major beat-and-raise quarter, with adjusted earnings per share of $25.11 versus expectations near $20.86. Guidance for the August quarter was even stronger, with expected EPS of $30 to $32 versus estimates closer to $25.72. Management pointed to tight memory supply, strong AI-related demand, and strategic supply agreements that improve revenue visibility. Micron’s stock surged more than 15% on Thursday, and the semiconductor index rebounded sharply.
Rising memory prices are great for memory producers, but they are a cost problem for the companies buying those components. Apple dropped more than 6% after raising prices on certain MacBook and iPad models, with the MacBook Neo’s starting price reportedly moving to $699 from $599. Microsoft also faced pressure after price increases tied to higher memory and storage costs. Amazon and Alphabet remained weak as investors questioned whether the hyperscalers’ AI capital spending will translate into attractive returns quickly enough.
By Friday, the AI trade was again under pressure after reports that OpenAI may delay its IPO until 2027 and that the Trump administration asked OpenAI to limit the initial release of its next model over security concerns. SpaceX also remained volatile after its massive IPO and reports of a new Starlink mobile push.
Investment implication: AI demand remains powerful, but investors are distinguishing between companies with pricing power from scarcity and companies exposed to rising input costs, capital intensity, and valuation risk – a 2026 story for sure.
Crude Cracks, Rotation Rips
While technology dominated the headlines, one of the most important market supports came from oil. Earlier this month, Middle East tensions had pushed crude sharply higher, with WTI trading near the upper $80s and Brent around $90 at one point. This week, reports of progress in U.S.-Iran negotiations, sanctions waivers, and improving tanker movement through the Strait of Hormuz helped ease supply fears. WTI crude fell back below $70 intraday, while Brent settled near its lowest levels since before the latest phase of the Iran conflict.
That decline mattered because oil had become a swing factor for inflation, consumer confidence, airline margins, and interest-rate expectations. As crude retreated, the market started rewarding areas that had been under pressure from higher fuel costs and higher yields. Airlines were among the clearest beneficiaries. United Airlines (UAL) rose more than 7% on Wednesday as crude fell, while travel names such as Booking Holdings (BKNG) and Expedia (EXPE) also moved higher. Homebuilders rallied as well, with PulteGroup (PHM), Lennar (LEN), and the iShares U.S. Home Construction ETF (ITB) gaining ground as Treasury yields eased.
Industrials were another standout. Caterpillar (CAT) moved to all-time highs, and the broader industrial sector led the market on Thursday with a gain above 2%. The strength was not limited to machinery. Infrastructure and construction-related names also remained in focus after CRH (CRH) announced an $8.5 billion deal to acquire Arcosa (ACA), while Chevron (CVX) and Microsoft signed a 20-year agreement to power a West Texas data center project using natural gas generation, including equipment from GE Vernova (GEV) and Caterpillar’s Solar Turbines.
The rotation showed up clearly in market internals. On several days this week, the market-cap-weighted S&P 500 struggled because of weakness in mega-cap technology, while the equal-weighted S&P 500, the Dow, small caps, mid-caps, health care, utilities, staples, real estate, and industrials performed better. That does not mean the market was immune to volatility. It means investors were not simply exiting equities. They were rotating within equities.
Health care also contributed to the broadening. AbbVie (ABBV) agreed to acquire Apogee Therapeutics (APGE) in a cash deal valued around $10.9 billion, adding to the sense that large-cap companies are using strong balance sheets to buy growth. Bio-Techne (TECH) also surged after agreeing to be acquired by Merck KGaA (MKGAY) for $73 per share in cash.
Investment implication: lower oil prices and falling yields helped broaden leadership beyond mega-cap technology, making market participation more balanced even as index-level volatility remained elevated.
Data Boxes the Fed
The week’s economic data was not weak enough to give investors a clean interest-rate relief story. First-quarter GDP was revised up to a 2.1% annualized pace from the prior 1.6% estimate. The improvement was driven largely by a downward revision to imports, which mechanically raises GDP because imports subtract from the calculation. Still, the headline revision helped reinforce the idea that the economy entered the second quarter with more momentum than previously thought.
The consumer also looked firmer in May. Personal income rose 0.7%, disposable personal income rose 0.7%, and personal consumption expenditures rose 0.7%. Importantly, real PCE rose 0.3%, showing that spending growth was not purely the result of higher prices. That matters for second-quarter GDP estimates because consumer spending remains the largest part of the economy. At the same time, the inflation numbers were not benign. The PCE price index rose 0.4% in May, while core PCE rose 0.3%, keeping pressure on the Federal Reserve to remain cautious.
Business investment was another bright spot. Durable goods orders fell 4.5% in May, but that headline number was distorted by transportation. Excluding transportation, durable goods orders rose 1.3%, and nondefense capital goods orders excluding aircraft rose 1.6%. That core capital goods measure is closely watched as a proxy for business equipment spending, and its rebound points to continued investment in machinery, technology infrastructure, and AI-related capacity.
Banks also received a tailwind after the Federal Reserve’s annual stress tests. Major banks announced dividend increases and buyback plans, including JPMorgan (JPM) raising its quarterly dividend to $1.65 from $1.50 and authorizing a new $50 billion repurchase program. Goldman Sachs (GS) raised its quarterly dividend to $5.00 from $4.50. Combined with stronger deal activity, this helped keep financials relevant in a market otherwise dominated by AI and macro headlines.
Investment implication: the challenge is that stronger growth, resilient spending, firm inflation, and improving capital investment do not give the Fed a simple reason to pivot dovishly.
Bottom Line
This week was less about a broad market breakdown and more about a leadership test. AI remains the central growth engine, but the trade is no longer moving in one direction. Memory producers benefited from scarcity, while large technology platforms faced higher costs, valuation scrutiny, talent losses, and regulatory uncertainty. At the same time, falling oil prices and easing yields helped capital rotate into industrials, homebuilders, airlines, health care, banks, and other parts of the market that had been overshadowed by mega-cap technology.
The message from the week is that the market is becoming more selective. Strong economic data, resilient consumers, firm business investment, and bank capital returns all argue against a recessionary backdrop. But sticky inflation, elevated AI valuations, and rising input costs argue against complacency. For investors, the most important development may be that market leadership is broadening, but not because the risks have disappeared. It is broadening because investors are starting to separate durable earnings power from crowded enthusiasm.
