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.See Eric’s full analysis and get all 7 free trade ideas here5/1/2024 BNP Paribas Financial Markets46,549$36K0.0%-19.8%0.031% 5/1/2024 Mirae Asset Global Investments Co.

Then an MIT team cracked the code… dropping the cost from $63,000 to just 90 cents per gram. Now, one US-based factory is gearing up to supply the AI, aerospace, and EV industries with the one material they can’t continue to grow without. Only one company controls it, and its stock is still flying under Main Street’s radar.See why the race for supply has already started.5/15/2023 Atom Investors LP90,388$512K0.3%-5.4%0.071% 5/12/2023 Profund Advisors LLC44,859$254K0.0%N/A0.035% 5/11/2023 PFG Investments LLC20,500$116K0.0%N/A0.016% 5/11/2023 FMR LLC18,911,458$107.23M0.0%+1.2%14.794% 5/11/2023 Knott David M Jr315,000$1.79M0.7%+57.4%0.246% 5/11/2023 E Fund Management Co.
