In the Fidelity Insight of the week, Business Insider executive editor Sara Silverstein speaks to Ford O'Neil, a fixed-income fund manager at Fidelity. He says that as the Fed prepares to unwind its massive balance sheet, there will be pressure on both interest rates and mortgage spreads. In terms of the stocks versus bonds debate, he notes that the equity market is embracing President Trump's pro-business agenda, while bonds are more mixed. O'Neil then says that low rates in Europe and Asia are driving overseas demand for US rates. Lastly, he says that corporate credit spreads are priced to perfection, and predicts that they'll be wider in a year.
