AI Rally Reignited on Wall Street: Hidden Variables Amid Economic Uncertainty

The New York stock market closed higher on June 30 (local time), powered by a rebound in technology shares. The Dow Jones Industrial Average rose 0.26% to 52,317.81, the S&P 500 gained 0.78% to 7,498.79, and the Nasdaq jumped 1.52% to 26,213.72, capping a strong finish to both the quarter and the first half of the year.

Once again, AI-related technology names led the advance. NVIDIA climbed more than 2%, while semiconductor-equipment makers like KLA and Apple rallied between 2% and 8%, driving gains in the S&P 500 and the Nasdaq. The CBOE Volatility Index (VIX) fell over 6% into the mid‐16 range, signaling a renewed appetite for risk assets.

Macro data delivered mixed signals. June’s Conference Board Consumer Confidence Index slipped to 91.2—below the 94.8 consensus and its lowest level in nine months—stoking fears of an economic slowdown in the second half. At the same time, the Job Openings and Labor Turnover Survey (JOLTS) and services‐sector indicators pointed to still‐solid demand for labor and services.

U.S. Treasury yields rose amid growing expectations of an extended period of high interest rates from the Federal Reserve. The 10-year yield climbed to about 4.46%, boosted by comments from the president of the Federal Reserve Bank of Cleveland, who warned that additional rate hikes could not be ruled out if inflation does not subside.

On the corporate front, though the earnings season is yet to ramp up fully, beneficiaries of AI investment as well as industrial and materials stocks all posted gains, reaffirming a market focus on names with visible earnings momentum. After the close, Nike reported fiscal Q4 results that beat profit forecasts but showed declining revenue and offered a conservative outlook, sending its shares lower in after‐hours trading.

On the global stage, crude oil prices held in the low‐$70-per‐barrel range. Expectations of easing tensions in the Middle East and possible U.S.–Iran talks in Doha, along with concerns over rising supply, kept downward pressure on oil—weighting energy names but alleviating inflationary and future‐rate concerns. Gold edged lower amid a firm dollar.

In sum, today’s session pitted economic uncertainty against AI and large‐cap tech momentum—and the latter prevailed. For Korean investors, a selective approach focused on leading technology and industrial stocks that can sustain earnings and growth narratives appears more effective than fixating on short-term index levels, given cooling consumer sentiment and the Fed’s hawkish stance.
