Here are 5 key events that drove the stock market last week (www.cnbc.com)

Last week, U.S. stock markets experienced volatility driven by developments in the artificial intelligence (AI) sector, culminating in gains for the S&P 500 and Nasdaq. The S&P 500 edged up by 0.1%, and the Nasdaq rose by 0.5%, as investors responded to significant movements, particularly in companies like Nvidia and Oracle. Nvidia's stock benefited from the U.S. government’s potential approval for shipments of its H200 chips to China, while Oracle’s shares rallied after TikTok agreed to a joint venture involving its U.S. operations, helping to mitigate concerns over funding for AI projects. This week highlighted the intertwined nature of AI advancements and market performance, underscoring the significance of chip manufacturers in driving tech stock valuations. Nvidia’s share price is now trading at a relatively lower multiple compared to its historical averages, indicating potential growth. Such developments are critical for the AI/ML community, not just for the immediate financial implications but also for reflecting the increasing reliance on AI technologies in mainstream business operations, shaping future investment and innovation strategies.
