Marc Chaikin, founder of Chaikin Analytics, is sharing a strategy he calls 'Sell This, Buy That' - a way to move out of overpriced AI stocks before the tech trade breaks down and into lesser-known names with real potential to challenge the Mag 7. One pick he calls 'an upgrade to Tesla stock' is a little-known company that just inked a partnership with Nvidia, positioning it ahead of Tesla in the autonomous vehicle race.tc pixel

A few little-known companies control the entire supply chain - meaning anyone who wants access must go through them. Their stocks are available to buy right now.tc pixel
