US stocks surged on Thursday as investors welcomed signs of easing geopolitical tensions in the Middle East, a sharp rebound in semiconductor stocks, and optimism surrounding the largest IPO in US history. The rally marked the strongest single-day advance for the major indexes since April, driven by improved risk appetite and relief over potential diplomatic progress.
Market Indices Performance
The major indices posted significant gains, with technology and semiconductor stocks leading the recovery. The Philadelphia Semiconductor Index surged nearly 8%, recording its strongest one-day gain in more than a year.
| Index | Gain (Points) | Gain (%) | Close Value |
|---|---|---|---|
| S&P 500 | 127.31 | 1.8% | 7,394.30 |
| Dow Jones Industrial Average | 929.97 | 1.9% | 50,848.75 |
| Nasdaq Composite | 640.16 | 2.5% | 25,809.66 |
Geopolitical and Economic Drivers
Investor sentiment improved after President Trump announced that planned military strikes against Iran had been canceled amid reports of progress toward a potential diplomatic agreement. Hope that the Strait of Hormuz could eventually reopen to normal shipping traffic helped drive oil prices lower and eased concerns about additional inflationary pressure from energy markets.
However, economic data released Thursday showed Producer Price Index (PPI) inflation rose more than expected in May. The report signaled that price pressures remain elevated despite recent signs of moderation elsewhere in the economy, tempering expectations for near-term Federal Reserve rate cuts.
Sector Moves and IPO Activity
Technology and semiconductor stocks led the market higher following several days of heavy selling, as investors returned to AI and chip-related names. Among notable movers, Oracle fell more than 8% despite reporting strong earnings, as investors reacted negatively to plans for significantly higher capital expenditures and additional fundraising for AI infrastructure. Adobe also traded lower ahead of its earnings release.
Markets also monitored developments surrounding SpaceX's highly anticipated IPO, which was priced at $135 per share and valued the company at approximately $1.77 trillion. The offering generated significant attention across financial markets and helped support broader risk appetite throughout the session.
Will the diplomatic progress with Iran be sustained enough to prevent a resurgence in oil prices?
How will the unexpected rise in PPI influence the Federal Reserve's interest rate decision timeline?
Can the semiconductor sector maintain its momentum after the recent sharp rebound?
