Rob Shaker, portfolio manager at Shaker Financial, says that the current market has been hard on closed-end funds because closed-end instruments suffer any time there is fear-based selling. He warns against trading any time CNBC carries a graphic saying 'Markets in turmoil.' Yet, he adds, troubling times also make closed-end funds compelling values, so long-term investors want to be prepared to step in once they are comfortable that the market has stabilized, and he talks about whether that time is now, when the market has rebounded for a few days.
