William Blair and Oppenheimer Downgrade Nvidia to Neutral Ratings

Wall Street firms William Blair and Oppenheimer have both stepped back from bullish stances on Nvidia Corporation, cutting their ratings on the artificial intelligence chipmaker to neutral equivalents. Analyst Sebastien Naji of William Blair downgraded Nvidia from Outperform to Market Perform amid heightened sector expectations, valuation concerns, and scrutiny over hyperscaler capital expenditure sustainability. This followed an earlier downgrade by Oppenheimer analyst Rick Schafer, who reduced Nvidia from Outperform to Perform, pointing to high sector expectations, supply chain conditions, and mega-cap semiconductor valuations.
