Matthew Liebman, founding partner and chief executive officer of Amplius Wealth Advisors in Blue Bell, Pennsylvania, said he’s starting to add high-quality bonds to clients’ portfolios. “The yields are as attractive as they’ve been in 20 years, give or take,” Liebman said. Investors who pair high-quality stocks with high-quality bonds can do really well. But he added, “Don’t buy anything just for the yield. You need a better reason than that.”
