Stock Indices Rally on Strong Tech Earnings and US-Iran Peace Hopes
US stock indices rose to record highs as investors weighed strong Q2 tech earnings expectations. Bloomberg Intelligence projects Q2 earnings up about 23% for S&P 500, with 86% of 322 reporters beating estimates. Markets priced a 59% chance of a 25 bp Fed hike and 85% for an ECB hike. SOX and AI chip stocks led; oil fell and energy stocks lagged.
How this was made
The 30-second read
Why it matters
Traders can use the named earnings/guidance beats and misses to trade single-name momentum, while the macro section (oil down, yields down, FOMC/ECB probabilities) informs broader risk and duration positioning.
Market read
This is a market wrap with multiple same-day, company-specific earnings and guidance catalysts plus analyst downgrades, set against a macro backdrop of lower oil and shifting central-bank expectations.
What to watch
The article highlights rate-hike probabilities and geopolitical Strait of Hormuz risk, which can quickly reverse risk appetite even if tech earnings are strong.
Background
The piece frames a US equity rally around strong Q2 earnings expectations, AI spending read-through, and a macro backdrop of falling oil and rate-hike probabilities.
Ticker impact
ARM is cited as up more than +12% on the day, tied to the article’s broader AI-infrastructure earnings optimism.
Likely supports continued relative strength while the market stays focused on AI infrastructure earnings.
The article provides a same-day price move for ARM but does not disclose a new ARM earnings/guidance datapoint beyond the rally context.
Marvel Technology (MRVL) is listed as up more than +10% as chipmakers and AI-infrastructure stocks rally.
May remain bid intraday and in the near term if the AI-earnings narrative persists.
The text gives a same-day performance figure but no MRVL-specific fundamental update.
Sandisk (SNDK) is reported up more than +8% alongside the semis-led rally.
Supports a momentum bias while semis remain the market’s leading factor.
The article includes SNDK’s price action but no new SNDK earnings or guidance details in the body.
Intel (INTC) is cited as up more than +8% during the AI-infrastructure and chipmaker rally.
Could track the broader semis tape rather than idiosyncratic catalysts.
Only a same-day price move is provided; no INTC-specific earnings/guidance numbers are included in the body.
Advanced Micro Devices (AMD) is reported up more than +7% and also appears in the earnings list for 8/4/2026.
Near-term performance likely remains correlated with AI/semis sentiment.
The body gives AMD’s intraday move and mentions AMD in an earnings calendar, but does not disclose AMD’s actual earnings/guidance figures here.
Micron Technology (MU) is listed as up more than +6% as AI-infrastructure stocks rally.
May continue to outperform if the market sustains AI infrastructure earnings expectations.
The article provides MU’s price action but no MU-specific fundamental update.
KLA Corp (KLAC) is reported up more than +5% in the semis-led rally.
Likely to remain supported while the market stays focused on AI infrastructure earnings growth.

Market effects
AI infrastructure and semis are the primary upside engine, while energy and service providers are pressured as WTI falls.
European and Asian indices are higher, reinforcing a global risk-on tone alongside US tech earnings optimism.
Lower oil supports disinflation expectations, which can reinforce equity duration and rate-sensitive tech multiples.
Counterpoint
The rally may be more about macro positioning (rates and oil) and broad AI sentiment than about durable, company-specific earnings quality across the tape.
