From the man who predicted 2008 crash… (Ad)

Porter Stansberry, founder of one of the largest financial research firms in the world, says he's breaking the biggest story of his 26-year career - an economic shift not seen since 1776. From the government taking stakes in Intel, Lithium Americas, and MP Materials, to sweeping political changes reshaping the economy, Stansberry argues a rare 'New 1776 Moment' is already underway. One Nobel Prize winner calls it a dividing line for all of society. His presentation covers the stocks to buy, the stocks to sell, and three money moves to position yourself on the right side of this shift.tc pixel
