The Market Takes the Optimistic Read
Stocks rallied broadly, with the Nasdaq up 2.13%, after President Trump said he had called off planned strikes on Iran and that Hormuz talks would begin Monday — a claim Iran's foreign ministry disputed even as WTI crude fell 5.44% and the 10-year Treasury yield eased 7 bp off last week's highest level since January 2025. A stronger-than-expected ISM Manufacturing PMI (55.6 versus a 54.0 consensus) added a second tailwind, and memory and AI-chip stocks recovered from an early slide tied to new Chinese AI-model competition to close broadly higher.

What Moved It
- WTI crude fell 5.44% to $80.06 after President Trump said he had called off a "massive" planned strike on Iran and that U.S.-Iran talks would begin Monday to reopen the Strait of Hormuz; Iran's foreign ministry disputed that any bilateral negotiations were underway, saying only Oman-mediated technical talks on the strait's shipping routes were in their "final stages." The 10-year Treasury yield fell 7 bp to 4.68%, its first meaningful retreat from last week's push to its highest level since January 2025, as the same oil move eased near-term inflation pressure.
- The ISM Manufacturing PMI rose to 55.6 in July, comfortably above the 54.0 consensus and up from June's 53.3, the clearest signal yet that the sector's summer slump has turned; the print helped anchor a broad-based rally that left the Nasdaq (+2.13%) ahead of the S&P (+1.48%) and Dow (+1.32%).
- Memory and AI-chip names opened sharply lower — the Philadelphia Semiconductor Index fell more than 2% at the open — after Alibaba unveiled a new flagship AI model, Qwen3.8-Max, and a research note flagged Chinese developer DeepSeek's latest model as more than 100 times cheaper to run than Anthropic's Claude Fable 5, reviving worries about China's AI cost advantage. The group pared its losses through the session as the broader rally took hold: Micron closed up 0.79% and SanDisk gained 6.03% after both opened lower.
Notable Movers
Extended a multi-session rally in AI-data-center optics names — Applied Optoelectronics and Lumentum also rose last week — as investors price in sustained hyperscaler infrastructure demand ahead of the company's Aug. 12 earnings report.
Opened lower on the morning's China-AI-competition scare but reversed to close higher, as investors continued to price persistent NAND and DRAM scarcity — forecasters see memory prices rising as much as 25% sequentially this quarter — ahead of the company's Aug. 5 earnings.
Wolfe Research cut the stock to Peer Perform from Outperform on competitive pressure from VantageScore, compounding last week's narrow fiscal third-quarter revenue miss ($674.2 million versus a $676.4 million estimate) despite an EPS beat.
Tracked crude's slide as WTI fell 5.44% on today's reduced near-term war-risk pricing; the smaller equity move than the commodity's drop suggests some of the war premium was already priced out of E&P shares before today.
The Jade Standard Lens
Sunday's Lens flagged an unresolved Hormuz outcome as a discount-rate variable in its own right, distinct from the earnings story running through the rest of this market — and today's tape is the first real data point on how the market resolves that variable when the underlying facts are still genuinely disputed. Trump said talks begin Monday and a deal is close; Iran's foreign ministry said the opposite, confirming only a narrower Oman-mediated conversation about shipping logistics. The market took Trump's framing anyway: WTI fell 5.44%, the 10-year eased 7 bp off last week's high, and equities rallied broadly. That asymmetry is worth naming on its own terms — the tape re-prices quickly toward the optimistic read on a war premium, and on the evidence of the past two weeks, re-prices just as quickly back the other way when the pessimistic read returns. The discount-rate logic behind that asymmetry cuts both ways for anyone holding duration into a week with no confirmed deal yet.
A second, unrelated thread tested the spenders-versus-takers framework from a new angle: not whether AI capex converts to revenue, but whether the moat behind that capex is as durable as the market has been pricing. Alibaba's new flagship model and a research note on a Chinese rival's cost advantage over Western frontier models hit memory and AI-chip names hard at the open — the semiconductor index fell more than 2% — before the session's broader tailwinds, the ISM beat and the oil-driven risk-on move, fully absorbed it; Micron and SanDisk both finished green. A credible cheaper-competitor story moved the tape for part of a session before the macro backdrop overwhelmed it, a different outcome from Apple's scarcity story last Friday, which held for the full session because nothing offset it. Whether that is durable evidence the market has already priced in Chinese AI competition, or just an unfavorable day for a real risk to get its full hearing, is a live question worth carrying into AMD's Wednesday report.
On Watch
- Whether the Trump-described Iran talks and Hormuz framework materialize this week, given Tehran's same-day denial that bilateral negotiations are underway — a sharper version of the conditional-pause risk flagged Sunday.
- AMD's Wednesday report, now also a test of whether today's Chinese AI-competition scare was a one-session non-event or the start of a real repricing of chip-sector moats.
- Friday's jobs report against today's 7-bp yield pullback — whether cooling oil-driven inflation expectations and the labor data end up pointing the same direction for the Fed, or diverge.
- Palantir reports after today's close, the week's first earnings read on AI and government demand.
