The retirement stock I'd buy before Nvidia today (Ad) In 2014, Marc Chaikin pointed readers toward Nvidia. Now the 60-year Wall Street veteran and creator of the Chaikin Money Flow indicator has a new top retirement pick. The company holds three fast-growing businesses -- including an autonomous vehicle unit and a streaming service with 10x Netflix's reach -- any of which could be spun off in the next 12 to 24 months. It also pays a dividend, a rarity among high-growth AI names. Chaikin lays out the full case in a new free presentation, no email or credit card required.
