Wall Street Turned Upside Down by AI Frenzy, Only Energy Thrived

On the 17th local time, New York stock markets all closed lower as profit-taking intensified among AI-beneficiary stocks. The S&P 500 fell 1.0%, the Dow Jones lost 0.8%, and the tech-heavy Nasdaq dropped 1.4%. This marked the first weekly decline in three weeks, reflecting growing fatigue in the AI rally.

The markets were weighed down by semiconductors and mega-cap tech stocks. The Philadelphia Semiconductor Index slid more than 20% from its June peak, entering bear-market territory, while major AI-linked large caps such as Meta and Alphabet each fell over 2%. Investors, concerned that the AI capital expenditure cycle may have peaked, are beginning to reexamine growth-stock valuations.

Fundamental indicators, however, supported the market. The June Consumer Price Index (CPI) fell 0.4% month-over-month, and the year-over-year rate slowed to 3.5%, pointing to faster-than-expected disinflation. Although the Fed Chair emphasized a “no tolerance” stance on high inflation, Wall Street widely interprets that the likelihood of further rate hikes at the July FOMC meeting has significantly diminished.

Real-economy data painted a mixed picture. June retail sales rose just 0.2% month-over-month, but core spending—excluding gasoline and autos—increased by 0.5%, indicating healthy quality of consumption. Consumer sentiment recovered to a five-month high, yet housing starts and permits declined slightly, and industrial production grew by only 0.1%, suggesting a modest slowdown in expansion.

On the corporate front, the Q2 earnings season got off to a strong start. Of the 49 S&P 500 companies that have reported, 90% beat market estimates, prompting the annual earnings growth outlook to be revised up from 19.2% to 26.0%. However, Netflix plunged over 7% on disappointing guidance, and Intuitive Surgical fell more than 10% amid growth concerns, as certain growth stocks underwent “expectation adjustments,” boosting index volatility.

A key global variable was the intensification of the conflict in Iran. Brent crude jumped around 4% and WTI soared to near $82 per barrel, each rising roughly 4%. As a result, the energy sector was the only gainer within the S&P 500, and Treasury yields dipped slightly, partially offsetting a broader risk-off sentiment. Investors faced a day of divergent paths: gauging whether the AI and semiconductor correction is merely a short-term pullback or the start of a broader revaluation, while reassessing energy and defensive sector exposure alongside messages from the Fed’s July meeting.
