Plenty of AI stocks trade down from their recent peaks, and the Nasdaq Composite, the tech-heavy index, hit an intraday peak on July 11. The index is down 5.5% from that peak after a recent recovery. Similarly, the VanEck Semiconductor ETF, which is led by the chip stocks that are key in the AI rally, is down 18% from its peak on the same day.

That massive gain was largely driven by the rapid expansion of the artificial intelligence (AI) market, which drove many companies to ramp up their purchases of the company's data center graphics processing units (GPUs) to process complex machine learning and AI applications.
