Furthermore if robo advisers really could make more money on a risk adjusted basis it would literally make them more money to use their own service than to sell it.
If there’s a single ETF that will do what Wealthfront and others are doing, I’d switch away in a heartbeat if the fees were lower.
But if you go from $50k to $500k with them you will be paying ten times as much (depending on the fee structure, of course). At some point, it may not be worth it.
Vanguard has more active management products, actually. Besides their Windsor fund, S&P 500 is an actively managed index.
An index ETF sure, but it might be worth paying for tax optimization over that.
If I’m wrong feel free to walk me through a 10 year period where any robo advised fund of your choosing has better return, risk and fee adjusted.
