Asian chip stocks surge on AI demand while South Korea's red-hot market cools sharply, exposing concentration risk and valuation concerns.
South Korean memory chip maker SK Hynix raised $26.5 billion in a landmark US listing, pricing shares at $149 and signaling confidence in AI-driven semiconductor demand. The offering is the year's largest equity raise globally and reflects booming appetite for the chips that power data centers and AI servers. Chip stocks across Asia rallied in anticipation, with the move underscoring how profitable memory-chip makers have become (CNBC, Investing.com).
The Kospi, Asia's best-performing stock index just months ago, plunged into bear market territory—down 20% from its June 19 peak—as investors abruptly soured on AI stocks and realized how dangerously concentrated the index had become (CNBC). Samsung and SK Hynix alone made up more than half the index's weight, meaning when chip sentiment shifted, the entire market got dragged down. What was once a strength—outsized AI exposure—became a liability overnight.
KB Financial Group's Peter Kim argues that modern stock markets increasingly whipsaw on news flows and fads rather than fundamentals, driven by retail fund flows, leveraged ETFs, and AI-focused algorithms. The Kospi's volatility index has surged over 200% since the start of the year, highlighting how trading has become divorced from actual business performance. Experts note this is part of a broader structural shift in how finance behaves in the era of passive investing and algorithmic trading.
