AI Rally Climbs as Oil Volatility Rattles Markets
U.S. markets saw divergent forces last week as ongoing enthusiasm for artificial intelligence lifted tech indexes while rising oil prices and renewed U.S.-Iran tensions injected volatility. Semiconductor stocks swung sharply after mixed company results and geopolitical headlines, with Apple expanding a multiyear chip partnership with Broadcom and SK Hynix debuting strongly in the U.S. Meta moved to monetize its AI investments — announcing plans for a cloud business, launching the Muse Image and Muse Spark 1.1 models and indicating it will charge developers — and Reuters reported Meta plans to manufacture a custom AI chip co‑designed with Broadcom and built by TSMC. Crude oil spiked after an attack near the Strait of Hormuz and subsequent U.S. strikes on Iranian targets, boosting energy names and pressure on companies sensitive to fuel costs and inflation expectations.
Meta and Microsoft Lead Tech Stocks Higher
Last week, tech stocks led by Meta and Microsoft surged despite soaring Treasury yields and Fed rate hike expectations. The Nasdaq rose 2%, S&P 500 gained 1%, while Dow edged up 0.3%. Meta's Connect conference unveiled plans to monetize its AI agent Muse via subscriptions and transaction fees, partnering with Walmart, Best Buy, Gap, and Shopify. Microsoft received analyst upgrades on accelerating Azure growth (43% YoY) and Copilot surpassing 30 million paid seats. These developments signal growing investor confidence in AI investments, though bond yields and inflation remain concerns.
Tech Stocks Rally After U.S. Ceasefire; Meta Debuts Muse Spark
U.S. and Iran agreed to a conditional two-week ceasefire that includes a temporary reopening of the Strait of Hormuz, triggering a global relief rally in technology shares. Earlier coverage noted broad gains for major U.S. tech names (Meta, Amazon, Alphabet, Nvidia) and the debut of Meta’s Muse Spark AI model; this CNBC piece highlights Asian semiconductor and equipment makers leading the surge. Taiwan Semiconductor Manufacturing Company, SMIC, Tokyo Electron, Advantest, Renesas, Fujikura, SK Hynix and Samsung all posted double-digit or high single-digit gains. Samsung also forecasted an eightfold jump in Q1 profit driven by AI demand for high-bandwidth memory (HBM). The article stresses lingering supply-chain risks — notably strained helium supplies after attacks on Qatari helium facilities (Qatar produces roughly 30% of global helium) — and notes oil prices fell on the ceasefire news, easing potential margin pressures for chipmakers.
