As Nvidia (NVDA) grows, so does A.I. infrastructure and the power grid, says Greg Dukes. He picks the Mag 7 giant as a company poised to grow for years to come but urges investors to look at other companies he expects to accelerate alongside Nvidia. Greg makes the case for Alphabet (GOOGL), Nextera Energy (NEE), and Caterpillar (CAT) as stocks to watch.
