Wrote a note about how @BillAckman would be better served in an ETF over a CEF, which will likely be plagued by premiums/discounts (like the one in Europe) which investors in US have shown they don't like. In the end it's personal choice but ETFs solve a lot of problems and reach widest poss audience a la Tom Lee, Dan Ives, Rick Rieder who all launched ETFs past two years and found instant and ongoing success. Proof ETF mkt hungry for Ackman's strategy is the launch of ACKY which is 13F holdings.(Eric Balchunas)
