Asian Tech Stocks Plunge as Apple Outlook and AI Fears Hit Regional Markets

Key points

• South Korea's Kospi index fell 4% to 5,626.08, with SK Hynix dropping 5.7% and Samsung Electronics declining 4%.
• Apple shares fell 1.8% after the company forecast lower gross margins and slower services growth, citing rising memory-chip costs.
• The Reserve Bank of Australia raised its benchmark rate by 25 basis points to 4.85%, the highest level since 2008, marking the fifth hike this year.
• Brent crude oil prices initially plunged 7.6% on Monday due to U.S.-Iran diplomatic hopes but rebounded 1% to $105.85 per barrel on Tuesday.
• China's Shanghai Composite index retreated 1.4% to 3,588.50, near its lowest level in over a year, despite recent market-supporting measures.

Background

This volatility follows a period of significant tech sector instability. In late October, Asian markets lagged U.S. rebounds as investors questioned the sustainability of AI infrastructure spending. Recent reports from Alphabet and other Big Tech firms have highlighted potential drag on core businesses due to heavy AI capital expenditure, fueling bubble concerns that have persisted for months.

How outlets are covering it

AP News emphasizes the broad regional weakness, noting that while the S&P 500 fell 0.5%, nearly 70% of its constituent stocks rose, highlighting a divergence between large-cap tech and the broader market. Yahoo Finance highlights the geopolitical angle, noting that oil price swings were driven by shifting expectations regarding U.S.-Iran relations and the upcoming U.S. midterm elections, which could alter the political landscape. Investing.com focuses on the corporate and regulatory drivers, specifically citing Apple's margin outlook and the Reserve Bank of Australia's split decision to hike rates. Seeking Alpha provides a structural view, noting China's shift in monetary policy anchors and mixed economic indicators, such as a manufacturing PMI above 52.0 but a non-manufacturing PMI in contraction.

Why it matters

The current market turbulence reflects deepening anxieties about the profitability of massive AI investments and the durability of the U.S. economic expansion. With oil prices swinging wildly due to Middle East tensions and central banks like the RBA tightening policy to fight inflation, global investors face a complex environment where geopolitical risks and corporate earnings are colliding. The upcoming U.S. midterm elections add another layer of uncertainty, potentially shifting the balance of power in Congress and affecting President Trump's policy agenda.

What to watch

Investors will closely watch corporate earnings from Apple, Advanced Micro Devices, and Palantir this week to gauge the health of the tech sector. The outcome of the U.S. midterm elections will be critical, as a potential Democratic takeover of the House could lead to a 'lame duck' period for President Trump, characterized by legislative gridlock and increased scrutiny. Additionally, the market will monitor oil prices for signs of stability following the reported U.S. strike on Iran's Qeshm Island and the ongoing diplomatic exchanges between Washington and Tehran.
