Doesn't the issue come down to who is programming the robo-advisor? The markets are ever-shifting with prices being set by marginal supply and marginal demand. Who is buying and selling is just as important as what is being bought and sold. As prices are bid up or down, the rules of the game change. As central banks alter monetary policy, the rules of the game change. As new companies or new management or new products or new industries emerge and compete with old line companies the rules of the game change. And on and on. Change is the one thing that is constant in investing. So, who is programming the robo-advisor? And is that person better than your advisor? It seems to me to be an important and often overlooked question.
