Sounds good in principle but how well does advice like this scale? Similar problem to Waze - side streets are great when you're the only one taking them, but once everyone does your advantage is gone. It's hard to expect a large population of amateur investors with no edge to outperform the market. In the general case, what's the marginal return on time and effort spent actively managing your money vs dumping it in a vanguard 50 and learning a different hobby?
