AI and Chip Investment Shock Valuation: Major S&P 500 Decline

The S&P 500 Index closed down -0.51%, the Dow Jones -0.20%, and the Nasdaq 100 -1.62%, as concerns over whether massive artificial intelligence investments will justify current lofty valuations rattled markets. A sharp -31% drop in Micron shares, alongside significant losses in Samsung Electronics and SK Hynix that drove South Korea's Kospi Index down -6%, heightened sector-wide risk aversion.

AI Investment Shock Valuation

- The Nasdaq 100 hit a 1-week low, falling -1.49%. - Alphabet shares dropped over -4% following reports of delays in delivering its most advanced AI model. - Cloud infrastructure and mining stocks slumped as gold, silver, and copper prices declined.

Corporate Earnings and Sector Rotation

- JB Hunt Transport Services rallied after reporting stronger-than-expected Q2 revenue. - Abbott Laboratories surged over +10% after raising its full-year adjusted EPS forecast. - While software and non-tech sectors saw investor rotation, overall market structure weakened.

Macro Data and Policy Implications

- Weekly initial unemployment claims unexpectedly fell to a 10-week low of 208,000. - The 10-year Treasury yield rose +2bp to 4.57%. - The Philadelphia Fed business outlook survey hit a 4.5-year high of 41.4.

Ege Kaan: The unchecked growth of AI investments is at odds with the Federal Reserve's aggressive inflation fight. Investors should view the current pullbacks in tech stocks like Samsung and SK Hynix as a critical risk indicator for global supply chains, while reassessing valuations amid hawkish monetary signals.
