Earlier quoted context omitted.
But why go with wealthfront when you can buy a target date fund from vanguard? It gets you most of what you really need?
If you just buy and hold a target date fund, you miss out on loss harvesting. A free loan on taxes owed can be turned into free money.
And fwiw, tax loss harvesting sounds complicated, but it really isn't that hard to do. If I notice stocks have gone down a lot recently, I'll hop into Vanguard, and swap anything that is underwater with another similar, but not identical fund. I have one for international and one for US stocks. Took me a few hours to get a system down, and now it's a few minutes to do the harvest once every few years.
