A friend of mine invested in two roboadvisors (wealthfront and betterment) at end of April and since then they have done nothing, not a single trade. Not a single trade. In the mean while, markets have scaled new heights. Ten year rate dropped to 1.37%!. Brexit happened. The FED unlike happened. There were huge gyrations in the unemployment rate. Vanguard systematic fund VMNVX did much better. I have worked in trading all my work life and I know how hard it is, how humbling it is, and how meaningful it is. I hate it when people sell crap as smart. As Dean Kansky in Serendipity said "They should make pills for this."
