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.

Do this before December or regret it (Ad) Porter Stansberry believes President Trump will use the December G20 Summit in Miami to unveil a radical monetary reset tied to executive order 14241 - one he says could draw a sharp dividing line between prepared investors and those left behind. The last time America reset its money - under Nixon in the 1970s - it produced an average of 1,300 new millionaires per day for over 50 years. Stansberry's new documentary names a core group of assets he believes are positioned to surge as Trump's new dollar rolls out. Watch Porter Stansberry's full briefing and get his three steps to prepare before December. Watch Porter Stansberry's full briefing and get his three steps to prepare before December.
