Stock Market Update

[BRIEFING.COM] The major averages are little changed from previous levels at midday.

NVIDIA (NVDA 230.12, +5.05, +2.24%) remains a notable outperformer despite broader semiconductor weakness after increasing its share repurchase authorization by $150 billion to $235 billion and launching its Open Agent Safety Platform. The announcements underscore NVDA's substantial cash generation from the AI infrastructure buildout while extending its full-stack strategy into AI safety as increasingly capable autonomous agents create new challenges around containment and deployment.

In other mega-cap news, SpaceX (SPCX 147.28, -1.40, -0.94%) is trading lower despite Starship reaching orbit for the first time and deploying 26 next-generation Starlink V3 satellites, suggesting a sell-the-news response after expectations rose ahead of the landmark Flight 14 mission. The flight was not flawless: one Starship engine shut down early, briefly creating doubt about orbital insertion, and mission managers shortened the planned 10-hour, six-orbit flight to roughly three hours, leaving reentry and splashdown as important remaining tests. The stock's decline indicates that investors are balancing today's major technical achievement against the unfinished work required to prove reliable reentry, rapid reusability, high launch cadence, and readiness for NASA lunar missions.

The Vanguard Mega Cap Growth ETF is down 0.8%.
