“Sell Nvidia before earnings” (Ad)

Eric Fry just went live with one of his most controversial calls yet: “Sell Nvidia.” While Wall Street has been chasing the AI giant, Eric says its biggest customers are now its biggest competitors — and that could spell trouble ahead. Instead, he’s urging investors to consider a little-known hardware company that’s already starting to take off. In fact, while Nvidia has slipped over the past 30 days, this “off-the-radar” stock is up 18% — and Eric believes the run is just beginning.tc pixel
