Maury Fertig, chief investment officer at Relative Value Partners, discusses the factors he considers when picking closed-end funds to add to client portfolios, and how those criteria have been impacted by headlines about rising rates and inflation, along with the stock market's heightened volatility and January losses. Fertig says that current conditions have changed some of his focus, moving him away from floating-rate funds -- which were trading at a significant discount a year ago, but which are close to net asset value now -- while convincing him to 'nibble' on some credit and mortgage funds that have fallen off in recent months, becoming more-attractive bargains as a result.
