Trump’s New Currency Reset (Ad)

Trump is launching a new $250 bill - but that may be a distraction. Behind the scenes, Executive Order 14241 is orchestrating what analyst Porter Stansberry calls a total U.S. money reset, bypassing conventional legal channels under the guise of national security. The last time America reset its currency - under Nixon in the 1970s - it created an average of 1,300 new millionaires a day for over 50 years. Stansberry has identified three asset categories connected to Trump's initiative that could surge, plus his single top investment move.tc pixel

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
