Trump Takes Emergency Action - Plus Elon Musk's New Venture (Ad)

Elon Musk has quietly launched a new venture - one that has nothing to do with rockets, EVs, or Neuralink.

A few little-known companies control the entire supply chain - meaning anyone who wants access must go through them. Their stocks are available to buy right now.tc pixel

The end may be near for these iconic stocks (Ad)

Marc Chaikin, founder of Chaikin Analytics, says two forces - AI disruption and fracturing global trade - are triggering a historic wealth transfer already underway in 2026. Household names like Intuit (-57%), Boston Scientific (-49%), and Tractor Supply (-40%) are cratering, while lesser-known companies like Sandisk (+573%) and Rackspace (+444%) surge. Chaikin has identified specific stocks he believes investors should sell before they fall further - and the names may surprise you. He's also pinpointing a company tapped as Nvidia's self-driving partner and a potential AI megadeal that could split into three high-growth stocks.
