Wall Street navigated a tumultuous week, with the dual forces of artificial intelligence enthusiasm and resurgent oil prices dictating market movements. The Dow Jones Industrial Average briefly touched an all-time high above 53,000, only to be pulled back by renewed U.S.-Iran tensions. Despite this volatility, the tech-heavy Nasdaq Composite and the S&P 500 both closed higher for the week, marking their fourth positive week out of the past five.
**The Semiconductor Rollercoaster: AI’s Double-Edged Sword**
Semiconductor stocks, the undisputed darlings of the market’s first half, continued to be a focal point of investor attention, exhibiting sharp swings. The week began with a surge, as the VanEck Semiconductor ETF climbed approximately 2% on Monday, fueled by renewed buying in some of the sector’s top performers. However, this optimism was short-lived. Tuesday saw a significant downturn following disappointing results from Samsung and reports of China’s DeepSeek developing its own AI chips. This news triggered a sell-off, with Micron shares falling 4.7% and the VanEck Semiconductor ETF shedding nearly 4%.
A stabilization occurred on Wednesday, bolstered by Apple’s announcement of an expanded, multi-year partnership with Broadcom, a deal projected to exceed $30 billion. This agreement will see Broadcom produce over 15 billion U.S.-manufactured chips, including a $1.5 billion expansion of its manufacturing facility in Fort Collins, Colorado. Broadcom’s shares responded positively, gaining nearly 5%. This was the second significant announcement between the tech giants this week, following Broadcom’s earlier filing detailing its agreement to supply Apple with custom ASIC (application-specific integrated circuit) silicon products. This collaboration is widely understood to involve the development of specialized AI server chips for Apple’s data centers, mirroring Broadcom’s existing co-design relationship with Google on its Tensor Processing Units (TPUs).
Amidst this sector-wide volatility, a strategic decision was made to exit the remaining position in Arm Holdings, locking in a substantial gain of approximately 69%. While the long-term AI buildout remains robust, the recent increased choppiness in the sector prompted a move to secure profits and reduce portfolio overlap with the burgeoning CPU renaissance, a theme now addressed by recent investments in Intel. Arm Holdings will continue to be monitored for potential re-entry at more attractive valuations.
The semiconductor rally reignited on Thursday, with the VanEck Semiconductor ETF advancing 2.5%, driven by substantial gains in Micron and SanDisk. However, Friday’s trading saw muted activity as investors shifted their focus to the highly anticipated U.S. market debut of SK Hynix. Concerns had been voiced that this new offering could draw capital away from existing chip stocks. The South Korean memory giant, which has experienced a remarkable year driven by soaring demand for AI-related memory, opened significantly above its offering price. Notably, Nvidia closed the week at its highest point in nearly a month, demonstrating resilience with a 4% gain on Friday.
**Meta Platforms: Monetizing the AI Revolution**
Meta Platforms spent the week actively addressing the critical question of how its substantial AI investments would translate into tangible returns. By the week’s end, the market responded with strong approval. The social media behemoth signaled its intent to launch a cloud computing business, offering its excess computing power to external clients. This strategic move positions Meta to compete directly with established players like Amazon Web Services, Microsoft Azure, and Google Cloud, as well as emerging niche providers.
Further demonstrating its monetization strategy, Meta launched Muse Image on Tuesday, an AI image-generation model designed to attract creators and advertisers. This technology will be integrated into Meta’s Advantage Plus advertising platform, streamlining ad creative development and automating marketing tasks. On Thursday, the company unveiled Muse Spark 1.1, an advanced model for coding and agentic AI tasks, which will be offered to developers for a fee – a notable shift from its previous emphasis on open-source releases. This move places Meta in direct competition with offerings from OpenAI and Anthropic.
Meta is aggressively scaling its infrastructure to support these ambitions. Reports indicate plans to commence manufacturing its custom AI chip in September, aiming to double its computing capacity next year. This internally developed chip, co-designed with Broadcom and manufactured by TSMC, could significantly reduce Meta’s reliance on Nvidia and AMD while potentially lowering its substantial computing costs.
The week culminated with Meta’s stock surging 6% on Friday, partly spurred by CEO Mark Zuckerberg’s comments in a Bloomberg interview. Zuckerberg suggested that the high demand for external compute rentals could, in some cases, make them more attractive than solely allocating resources for internal use. Meta’s stock, which opened lower on Monday, experienced a week of consistent gains, finishing up an impressive 15% and emerging as the week’s top performer.
**Oil’s Shadow: Geopolitical Tensions Resurface**
Renewed U.S.-Iran tensions cast a shadow over the market rally, highlighting the delicate geopolitical landscape. Crude oil prices surged on Tuesday after an attack on a Qatari liquefied natural gas tanker near the Strait of Hormuz reignited concerns about potential disruptions to critical energy shipping routes. These concerns intensified on Wednesday following U.S. military strikes on Iranian military targets.
The surge in crude prices, with WTI climbing back towards $76 a barrel, benefited energy stocks such as ConocoPhillips, Chevron, and Marathon Petroleum. Conversely, companies exposed to higher fuel costs faced pressure. Honeywell Aerospace, a holding, experienced its worst week, as investors worried that elevated oil prices and renewed conflict in the Middle East could curtail air travel demand, impacting aftermarket services and maintenance revenue.
The spike in crude oil also rekindled inflation concerns, pushing the 10-year Treasury yield to its highest level since May. While recent declines in oil prices had led the market to temper expectations for multiple Federal Reserve rate cuts, a sustained rebound in crude and subsequent inflation could bring those possibilities back into focus. The rise in bond yields adversely affected Home Depot, a holding positioned to benefit from a housing market recovery, as higher borrowing costs continue to dampen home improvement spending. DuPont also faced headwinds, with investors assessing the impact of higher energy prices on its input costs and regional business, particularly its water unit’s exposure to the Middle East.
By Friday, some of the pressure eased as oil prices pulled back following indications of renewed dialogue between the U.S. and Iran.
