Is Nvidia Stock a Buy?

Nvidia continues to deliver exceptional business results with 85% revenue growth and accelerating data center demand driven by agentic AI. However, the stock has stalled near all-time highs despite strong fundamentals. While the valuation appears reasonable at 31x P/E for a company growing this fast, investors should be cautious due to China revenue risks, potential competition from major cloud provider customers building their own chips, and AMD's advancing AI accelerators.
