. . . Do you believe active investment strategy could work-i.e., can you get a higher rate of return from an actively managed fund over long periods of time? Provide your reasoning. Why do you think actively managed funds are considered less cost- efficient? Is it justifiable? If passive investment strategies are better, why do hedge funds exist and why do many thrive? Can technology (i.e., robo investing) make active investing more attractive? If so, how?
