US Stocks Rise as CoreWeave Shares Surge and Nvidia Stabilizes

US stocks experienced a positive turn on Wednesday, with the S&P 500 and Nasdaq both rising more than 1%. This rally was largely driven by a significant rebound in CoreWeave shares, which surged nearly 25%, marking their largest daily increase in over three months. The company reassured investors by projecting profitability in the first half of 2028 on an adjusted basis, citing strong demand and customer commitments that could support its expansion efforts.

Investor sentiment also improved for other AI infrastructure stocks, with Nebius Group and Applied Digital seeing notable gains. Nvidia's stock stabilized following a sharp decline in market capitalization over the previous sessions, amid concerns regarding CEO Jensen Huang's connections to a businesswoman alleged to be a Chinese spy.

Market volatility has been a recent trend, influenced by worries about increased regulation in the AI sector following Democratic victories in the midterm elections, as well as concerns surrounding Nvidia's leadership. Thomas Martin, a senior portfolio manager, noted that investors are reacting to daily fluctuations in sentiment regarding AI.

The Dow Jones Industrial Average rose by 254.60 points, closing at 52,486.49. The S&P 500 gained 98.45 points to finish at 7,619.38, while the Nasdaq Composite increased by 400.31 points, closing at 25,466.19. The Philadelphia Semiconductor Index also saw a significant rise, closing at its highest level since early November.

Investors are closely monitoring inflation data, which has led to expectations of a potential interest rate hike by the Federal Reserve next month. Recent comments from Fed officials suggest a more aggressive approach to rate increases may be considered as inflationary pressures persist. The US bond market was closed on Wednesday for Veterans Day, and trading volume on US exchanges was lower than the recent average.
