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.

The cat is out the bag (Ad) Almost 80,000 tech jobs vanished in the first three months of 2026. Meta cut 14,000 roles, Microsoft offered separation packages to 8,500 workers, and Oracle is reportedly eliminating up to 30,000 positions. Goldman Sachs estimates 12,400 Americans are being financially displaced every single day. Analyst Porter Stansberry says the real driver runs deeper than AI - and two Nobel Prize winners have issued the same warning. He calls it the Final Displacement, and he's releasing a full investigation with specific companies to buy and sell before the next wave hits.
