US stocks hit records at open as Hormuz deal hopes lift sentiment
US stocks rose to record highs as hopes for a US-Iran deal to reopen the Strait of Hormuz lowered oil prices. S&P 500 gained 0.5% to an intraday record, Nasdaq 0.9%, and Dow up 1.4%. Treasury Secretary Scott Bessent said talks with Iran could yield an agreement Tuesday or Wednesday. Palantir, Caterpillar, Micron, and Marvell shares jumped on earnings.
How this was made

The 30-second read
Why it matters
The immediate tradable driver is the combination of lower oil prices on de-escalation hopes and same-day earnings/guidance catalysts for select names. The article also flags geopolitical controversy around Palantir, which can affect sentiment beyond the financials.
Market read
This is a market-move and catalyst mix: macro de-escalation hopes lower oil, while earnings/guidance raises drive outsized single-name moves (notably PLTR and CAT).
What to watch
For PLTR specifically, the article notes criticism tied to support for Israel’s Gaza war, which could drive post-earnings headline volatility even if fundamentals beat.
Background
US stocks reached record highs as optimism about possible US-Iran talks to reopen the Strait of Hormuz pushed oil lower, while several companies reported strong results or raised guidance.
Ticker impact
Palantir shares jumped more than 20% after reporting strong Q2 results and raising full-year forecasts.
Likely continued volatility and follow-through in the next session(s) given the magnitude of the forecast raise, with headline risk from the Gaza-support criticism.
The text attributes the >20% move directly to Q2 strength and full-year forecast increases, which typically sustains momentum, while the mention of criticism introduces uncertainty around sentiment and potential incremental scrutiny.
Caterpillar climbed about 10% after beating quarterly expectations and raising its revenue growth guidance.
Bias toward further upside or consolidation with elevated volume as traders digest the raised revenue growth outlook.
The article explicitly links the ~10% gain to both an earnings beat and an updated revenue growth guidance, a combination that is usually actionable for positioning.
Micron Technology gained 4% as the broader rally cited strong corporate earnings alongside the Hormuz-deal optimism.
Limited single-name edge from this article alone; any follow-through would likely track broader risk-on sentiment.
Micron is mentioned with a price move, but the text provides no Micron-specific new fact such as results, guidance, or a discrete catalyst.
Marvell Technology advanced 11% during the session as the article attributes the rally to strong corporate earnings and sentiment.
Potential continuation only if the market keeps rewarding semis broadly; this article alone is insufficient for a Marvell-specific trade thesis.
MRVL’s +11% is stated, but no Marvell earnings/guidance details are included, so the catalyst is not independently established in the text.
Market effects
Oil-price downside from Hormuz-deal hopes can ease input-cost and inflation fears, supporting cyclicals and semis.
US-focused risk sentiment; record highs suggest broad appetite for equities.
Potential US-Iran de-escalation narrative can influence global energy pricing and risk premia.
Counterpoint
The Hormuz-deal optimism may be speculative; if talks fail, oil could rebound and pressure the same risk-on complex that rallied on earnings.
