Nasdaq leads Wall Street gains as SpaceX, Super Micro boost AI sentiment

On Wednesday, October 21, the tech-focused Nasdaq propelled Wall Street to higher closes as the earnings of SpaceX and Super Micro Computer bolstered investor confidence in artificial intelligence-related stocks, while communication services stocks dragged on the gains. SpaceX shares surged by 7.8% following the company's first profitable quarter, with CEO Elon Musk suggesting a potential merger with Tesla.

Super Micro Computer's shares jumped 9.6%, after the AI server manufacturer exceeded Wall Street estimates for quarterly revenue and profit margins, signaling sustained AI demand. The favorable reports reassured investors concerned about the profitability and sustainability of massive AI investments. The tech sector had experienced a selloff the previous week due to concerns over AI-linked stocks, with CoreWeave being a key contributor.

Angelo Kourkafas, a senior global strategist at Edward Jones, noted that while the reports did not fully address investors' questions about AI returns, they provided a positive start. Marc Dizard, chief investment officer at Huntington Bank, emphasized that the technology market reaction reaffirmed the ongoing strength of the artificial intelligence trade.

Meta's shares rose 3% after it released its quarterly results, followed by a 1.6% increase in Tesla shares. The Dow Jones Industrial Average climbed 360.21 points, or 0.69%, to 52,856.09, while the S&P 500 gained 44.60 points, or 0.58%, to 7,757.17, and the Nasdaq Composite surged 278.04 points, or 1.05%, to 26,702.86. However, the gains were tempered by a 1.3% decline in communication services stocks, primarily due to telecom operators such as AT&T, which fell 6.5% despite meeting revenue and profit expectations.
