Chip Stock Selloff Deepens Globally as AI Valuation Fears Spread, Dragging Down Zhongji Innolight's Hong Kong Debut

Asian markets slid Wednesday as investors grew anxious about AI valuations and competition, ahead of critical Big Tech earnings and a Fed decision.

Asian and U.S. stocks have experienced a sharp, broad-based selloff centered on chip and AI-related equities, with declines deepening across multiple sessions. Reuters described the initial move as a 'brutal selloff' driven by mounting doubts about artificial intelligence valuations, rising competitive pressures, and concerns over the scale of AI-related capital spending. Chip stocks have been hit particularly hard. South Korean chipmakers were among the earliest and most severely affected, but the selloff has since extended to Wall Street, according to WSWS reporting. The BBC and Financial Times both confirm that chip stocks continued to slide in the U.S. and Asia as AI jitters intensified, with the FT characterizing the AI sell-off as deepening. The weakness has also weighed on new market entrants. Chinese optical transceiver maker Zhongji Innolight — an AI supply chain company — saw its shares fall on its Hong Kong Stock Exchange debut, despite having completed the city's biggest IPO of the year at $6.8 billion. The stumbling debut underscores how waning investor confidence in AI-related stocks is extending beyond established names to newly listed firms. The turbulence unfolded ahead of earnings reports from major technology companies and a U.S. Federal Reserve interest rate policy decision — two events capable of either stabilizing or further unsettling AI-heavy portfolios. Oil prices also rose during the same period, adding a separate layer of macroeconomic uncertainty. The episode reflects a broader investor recalibration after heavy capital flows into AI-related stocks over the past year. Questions about whether massive infrastructure spending by tech giants will translate into proportionate returns have grown louder, and the geographic spread of the selloff — from Seoul to Hong Kong to New York — underscores how globally exposed markets have become to shifts in AI sentiment.

Why it matters

Chip and AI-linked stocks have been among the biggest drivers of global market gains in 2024, so a sustained selloff in this segment could ripple broadly across equity portfolios worldwide. The upcoming Big Tech earnings and Fed decision will serve as a near-term test of whether the correction deepens or stabilizes.

What's next

Investors are watching closely for earnings reports from major tech firms and the Federal Reserve's policy decision, both of which could determine whether the selloff continues or reverses.

Key facts

• Asian stocks fell on Wednesday, July 29, extending a multi-session decline
• The selloff was driven by anxiety over AI valuations, rising competition, and AI capital spending levels
• Chip stocks were among the hardest-hit sectors in both U.S. and Asian markets
• Oil prices rose during the same session, adding broader macro pressure
• Major U.S. tech company earnings reports were imminent at the time of the selloff
• A U.S. Federal Reserve interest rate policy decision was also expected imminently

Bias & framing notes

Both sources agree on the core facts — a chip and AI-driven stock selloff across Asia and the U.S. Reuters (via Biztoc) provided the most detail, including the oil price move and the Fed decision context. The BBC headline was available but no body text was accessible, so specific figures, index levels, or percentage declines could not be confirmed from a second source, limiting corroboration of granular details.
