I use Wealthfront. Performance vs SPY is comparable, but it can depend on your risk preferences. I like it because it abstracts away the underlying securities & I don’t have to worry about it. I also like their feature that lets you borrow against your portfolio at a fairly low rate (less than 4% for me), which is a painless way to tap into credit if you need to for pick a reason. I think it’s a great option for anyone looking to keep investing as simple as possible.
