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.
