John Cole Scott, chief investment officer at Closed-End Fund Advisors and the founder and executive chairman of the Active Investment Company Alliance, revisits data used by his father George Cole Scott in writing "Investing in Closed-End Funds: Finding Value and Building Wealth," the seminal book on closed-end fund investing that was written 30 years ago. He examines changes in the industry -- moves away from single-country funds, dramatic growth amongst new funds and more -- and gives his take on what will be important for closed-end fund investors in the coming decade.
