Week in Review: AI Capex Overshadows Growth as Oil Rips on Hormuz Risk and Yields

Week in Review

The week began on a constructive note. Volatility had eased to a 17-handle and Tuesday's tape rotated back toward growth and semiconductors, with QQQ and XLK leading as risk appetite appeared to broaden beyond the narrow leadership of prior weeks — reinforced by domestic AI supply-chain headlines including new US chip manufacturing capacity coming online to supply Nvidia. That optimism did not survive contact with earnings season. As Wednesday and Thursday's mega-cap prints landed, Alphabet and Tesla both suffered sharp post-earnings selloffs that together erased hundreds of billions in market value, crystallizing a market-wide "AI capex overshadows growth" narrative: investors began actively discounting hyperscalers and AI-adjacent names whose spending is outrunning near-term earnings delivery, regardless of the strength of the underlying AI trend.

Crucially, the repricing was selective rather than a wholesale AI unwind. Google Cloud's disclosure of roughly 50% growth in customer spend confirmed that enterprise AI compute demand is real and accelerating, not narrative — which kept capital flowing into the suppliers of that compute even as the buyers were punished. Intel posted its fastest revenue growth in close to fifteen years riding the AI buildout, and semiconductor and custom-silicon leadership held up against a broad tape that otherwise weakened, with Nvidia and Broadcom both outperforming through the second half of the week. The bifurcation between rewarded compute suppliers and repriced capex buyers became the week's defining structural signal.

Layered on top of the earnings-driven rotation was a fresh and material geopolitical and rates shock. A live Hormuz-related tanker scare and escalating rhetoric pushed Brent crude briefly above $100 a barrel by Thursday, reigniting inflation concerns and sending the 10-year Treasury yield to its highest level since January 2025 near 4.70%. Higher real rates disproportionately pressured long-duration tech multiples, compounding the pain in the highest-multiple capex spenders, while financials — benefiting from higher net interest income and elevated trading volumes — continued to outperform (JPM's 60-day gain approached +9.6% into Friday). Oil and yields both eased somewhat into Friday's close on reports that Pakistan was exploring a path to restart US-Iran talks, but the retreat only partially unwound the week's move, and VIX firmed to roughly 18.7 by Friday after dipping into the 16-handle mid-week.

For the week as a whole, the Nasdaq Composite fell over 2%, the S&P 500 declined roughly 0.6%, and the Dow Jones Industrial Average slipped about 0.4% — a mixed scoreboard that understates the internal dispersion. Energy was the standout sector, gaining roughly 3.8% on the oil spike, while broad technology and growth names lagged. Financials and healthcare again outperformed broad tech on a 60-day basis, extending a leadership pattern that has now held for several weeks. The net regime signal is a market that is no longer rewarding the AI trade indiscriminately: it is paying for validated compute demand and cyclical earnings power, and discounting unvalidated capex — with a geopolitical energy shock now sitting squarely on top of that re-rating rather than in the background.

Next Week Outlook

The coming week is dense with scheduled catalysts that will test both halves of the current bifurcation. The FOMC meets Tuesday and Wednesday, with its rate decision due Wednesday, July 29 at 2:00 p.m. ET followed by Chair Warsh's press conference; fed funds futures are pricing roughly a one-third probability of a hike this meeting against a low-60s hold, with September hike odds running near 80% — an unusually live near-term hike probability that reflects the oil-driven inflation scare rather than a settled consensus. Any language that leans into that scare, or conversely downplays it, will move the rate-sensitive positioning that has favored financials over long-duration growth. Thursday brings US Q2 GDP, ADP employment, and pending home sales; Friday brings the June PCE inflation print, Chicago PMI, and personal income/spending; Saturday's ISM Manufacturing PMI closes out the week. A hawkish hold layered on a still-hot PCE print would extend the yield-driven pressure on the highest-multiple names.

The week's most consequential earnings cluster lands squarely inside the current market leadership debate. Microsoft and Meta both report Wednesday, July 29 after the close — Meta's print is a direct read-through for the "AI capex overshadows growth" thesis one week after Alphabet's capex-driven repricing, with its AI-advertising monetization and Llama/data-center spend guidance determining whether it is grouped with the punished capex buyers or spared as an ad-revenue compounder. Apple and Amazon follow Thursday, July 30; Amazon's AWS growth and forward capex commentary matter for the broader narrative and its read-through to compute demand across the sector. A cluster of four mega-cap prints in two days, arriving in the same week as the Fed decision, raises the odds of a sharp single-session re-rating in either direction for AI-adjacent names.

The Hormuz-driven energy and rates shock remains the wildcard layered on top of the earnings and Fed calendar. The Pakistan-mediated peace-talk overture that helped ease oil and yields into Friday's close is a genuine de-escalation path, but the tanker-strike-and-threat cadence seen since April means the risk premium can reprice quickly in either direction on a single headline. Readers should watch oil (a sustained break back above $100 versus a durable retreat toward pre-shock levels) and the 10-year yield as the fastest-moving signals of which regime — de-escalation-and-relief or renewed supply-shock-and-hawkish-hold — is taking hold, since either one will do more to move rate-sensitive equity leadership next week than the scheduled data alone.
