Chip Rout and Middle East Tensions Offset Earnings Optimism as US Stocks Diverge
TREE NEWS reports: US equities closed mixed on Monday as investors weighed upbeat corporate earnings expectations against escalating geopolitical risks in the Middle East. The S&P 500 slipped 0.06%, the Nasdaq fell 0.44%, while the Dow Jones Industrial Average defied the broader trend with a 0.38% gain. Trading volumes were exceptionally thin, with total US exchange volume at 12.67 billion shares, well below the 20-day average of 17.62 billion. The bond market was closed for Columbus Day, leaving investors without fixed-income cues.
Memory Chip Stocks Tumble on Chinese Competition Fears
The technology sector was the worst performer, with the Philadelphia Semiconductor Index dropping 2.7% to a three-week low. The selloff was concentrated in memory chips after ChangXin Memory Technologies (CXMT) President Cao Kanyu announced a key breakthrough in next-generation 4F² DRAM cell architecture. The company plans to launch server memory products based on this design by the end of 2026, targeting high-margin DRAM used in AI servers.
Micron fell below the $1,000 mark intraday before closing down about 4%. SanDisk dropped nearly 6%, while SK Hynix ADRs and Super Micro Computer each fell more than 4%. Seagate lost over 3%, Quantum plunged more than 9%, and Corning also declined sharply. Smaller chipmaker Cerebras tumbled over 10% to a record low since its 2026 listing.
Not all tech names suffered. Meta Platforms rose more than 3% after unveiling its highly anticipated new AI model, lifting the communication services sector. Microsoft gained 1.1%, with its market capitalization surpassing $4 trillion for the first time in a year following its announcement of a large-scale deployment of self-developed AI chips. However, the broader AI basket significantly underperformed non-AI S&P 500 constituents, with cloud services and optical networking stocks leading declines.
Dollar Hits Cycle High, Pressuring Gold and Crypto
The US dollar rose to its highest level since May 2025, tightening financial conditions and weighing on risk appetite. EUR/USD fell 0.4% to 1.1154, GBP/USD dropped 0.2% to 1.3205, and USD/JPY climbed to 158.64. Spot gold declined 0.6% to $4,168.35 per ounce. Bitcoin retreated from over $84,000 to around $82,897, erasing weekend gains, while Ethereum fell 0.6% to $2,521.65.
Cleveland Fed President Beth Hammack’s hawkish remarks slightly increased expectations for a December rate hike, further pressuring rate-sensitive technology growth stocks.
Oil Rises on Middle East Escalation, but Gains Muted
Oil prices rose about 1.5% to $93.23 per barrel, a two-week high, driven by a series of Middle East tensions over the weekend. Houthi forces attacked Saudi Arabia’s King Khalid International Airport on Saturday, killing at least 12 people and injuring over 300, with a second strike on Sunday causing additional casualties. President Trump indicated Washington is considering joining Saudi strikes against the Houthis. Meanwhile, three oil tankers were attacked near the Strait of Hormuz and Gulf of Oman, with at least 17 tanker attacks reported since September 28.
Despite these events, the price increase was less than some market participants expected. Analysts suggest the market views the Riyadh airport attack as part of a “conventional conflict” between Saudi Arabia and Yemen rather than a sign of further escalation with Iran. Trump also announced relaxed sanctions on Russian diesel exports and declared an “energy ceasefire” between Russia and Ukraine effective immediately. However, Ukrainian President Zelensky said he was unaware of the statement, and Russia refused to confirm any agreement. Diesel prices rebounded on Monday, erasing Friday’s losses.
Notably, WTI cash roll premiums have returned to extreme levels, indicating significant tightness in the physical crude market. Brent spot prices are back above $130, near highs seen during the Iran war period.
Key Takeaways for Investors
- Earnings season takes center stage: With major bank earnings due this week, trading volumes and volatility are expected to pick up. The S&P 500 has gone 52 consecutive sessions without a daily drop exceeding 1%, matching a record set in July 2024. A break of this streak could signal a shift in market sentiment.
- Rate risk remains a threat: As Rebecca Patterson, former Chief Investment Strategist at Bridgewater Associates and now a senior fellow at the Council on Foreign Relations, noted, rising rates have not yet been seen as a force overpowering growth and earnings narratives. However, if rates continue to climb due to persistent central bank tightening, the risk of rates dominating and suppressing equity sentiment will increase.
- Geopolitical premium is building: While oil’s muted response suggests some market complacency, the physical market tightness and repeated tanker attacks could lead to sharper price spikes if the situation deteriorates.
- Dollar strength is a headwind: A stronger dollar tightens global financial conditions, pressuring commodities, emerging markets, and dollar-denominated assets like gold and Bitcoin.
