Gabe McNerney argues the traditional 60/40 portfolio is breaking down as stocks and bonds move together in a changing macro environment. He makes the case for commodities as a key source of diversification, citing rising industrial demand, structural supply constraints, and a softer U.S. dollar. McNerney highlights gold and industrial metals as core exposures, pointing to the Harbor Commodity All-Weather Strategy ETF as a way to navigate inflation and shifting global trade dynamics.
