Matt Freund, Co-Chief Investment Officer at Calamos Investments, says that productivity, GDP growth and earnings are "what matters," and that the headline risks that are driving consumer sentiment are "distractions" from a market backdrop that is solid. He says inflation remains the big risk, but notes that the investor sentiment is creating opportunities, particularly in closed-end funds, and especially in senior loans and high-yield bonds, where discounts have widened this year.
