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.tc pixel

Did you see the WSJ on 8-9? (Ad)

On August 9, the Wall Street Journal profiled a unique AI strategy used by three companies. Whitney Tilson of Stansberry Research says one of them has returned more than Apple, Amazon, and the S&P 500 index combined in recent years. One well-known Wall Street money manager reportedly has roughly half his entire fund in this stock. Tilson's free write-up names the company and ticker, with no subscription required.tc pixel
