How much better has wealth front done vs SPY, fee adjusted? Imho all robo advisers are a waste of money. If they were actually effective they’d use their own services themselves as opposed to sell them to retail. The latest crop of businesses really are marketing value adds. See: https://longbets.org/362/ Other people have done similar bets and they all lose on a risk adjusted, fee adjusted basis.
These investing middlemen have all been obviated by automation. No one is beating the 0.03% to 0.15% expense ratios for index ETFs/Target Date Retirement Funds from Vanguard/Schwab/Fidelity.
I personally have many friends who are very happy with betterment and wealthfront which is good. When I ask them about their returns in the past couple years they say that the stocks have done amazingly.
When I tell them SPY would’ve given them higher returns and lower fees they’re skeptical, and lo and behold when I actually show them they’re shocked.
I feel these companies survive on sheer inertia
