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.tc pixel

Why major institutions are piling into this digital asset now (Ad)

BlackRock, JPMorgan, Goldman Sachs, and Fidelity are reportedly accumulating a scarce blockchain asset - one that gets burned with every transaction on what analysts are calling America's new financial grid. The Nasdaq has received SEC approval to move stocks onto blockchain rails, and BlackRock CEO Larry Fink dedicated his entire 2026 annual letter to this infrastructure shift. Blockchain analyst Andy Howard is calling this asset 'Digital Oil' - and says institutional buyers are already positioned.tc pixel
