QtrendsWall Street indexes hold mixed as Alphabet slides, with the S&P 500 extending its winning streak to nine days amid thin breadth raising red flags. Trump signed an executive order requiring vetting of top AI models before launch, drawing mixed reactions from critics who call it scaled-back and almost meaningless. AI investment fever continues globally—Broadcom shines from Alphabet's AI spending, Asian firms chase AI despite scant returns, and AI is beginning to overwhelm court systems with surging pro se filings.
U.S. stocks were mixed Tuesday, with the S&P 500 climbing for a ninth straight session even as Alphabet shares slid. The Dow Jones Industrial Average pushed higher while the Nasdaq pulled back from session highs. Market breadth remains a concern despite the streak, with analysts warning that narrow leadership could signal fragility beneath the surface.
Optical and semiconductor stocks posted outsized gains Tuesday, led by Coherent, Lumentum, and Broadcom. Alphabet's aggressive AI infrastructure spending is providing a tailwind for Broadcom, which supplies custom AI chips. Marvell Technology and Hewlett Packard Enterprise also moved sharply as investors rotated into AI-related hardware plays.
Former President Donald Trump signed an executive order Tuesday that requires developers of advanced AI models to submit them for national security vetting before public release. The order is viewed as scaled-back compared to earlier drafts, with critics arguing it lacks enforcement teeth and may be largely symbolic. Supporters say it establishes a baseline for AI oversight without stifling innovation.
AI remains the dominant theme across global equity markets, with investors piling into the sector despite questions about return on investment. Asian-Pacific firms are chasing AI capabilities largely out of fear of missing out, according to a new survey. Meituan is betting $1 billion on AI and robotics as it posts a quarterly loss, underscoring how deeply the AI arms race is reshaping corporate strategy worldwide.
The rapid, often confusing rollout of AI tools is frustrating workers and baffling staff at many organizations, the BBC reports. In the legal system, AI is flooding courts with pro se lawsuits, overwhelming judges and clerks who now face a surge of AI-generated filings.
