Nvidia Hits a New All-Time High. Is the AI Stock a Buy?

Nvidia reached a new all-time high of $243.37 per share, driven by positive macro conditions and strong AI sector momentum. Trading at a P/E ratio of 30, the stock appears undervalued compared to peers like AMD (166 P/E) and Intel (103 P/E), with Wall Street expecting 67% revenue growth to $687 billion in fiscal 2028. While the law of large numbers may eventually constrain growth and competition from AMD, Intel, and custom chips from Amazon and Google pose risks, analysts view Nvidia as well-positioned to capitalize on AI growth and recommend it as a strong buy.

Here's Why SpaceX's AI Infrastructure in Space "Moonshot" Won't Uproot Neocloud Companies
