Some caveats with this approach:
1) Note that wealthfront charges a 0.25% annual fee for their service plus 0.02%. If you just bought all the stocks yourself from a discount broker like Vanguard, it would be $2 per trade for balances over $500k. Even if you bought or sold every single stock each year (which I don't recommend), your trade fees would be lower than wealthfront.
2) If you wanted to do this, I would actually recommend a buy and hold strategy, with only occasional rebalancing just to save the fees. This can be your alpha. You aren't paying the 0.05% for Vanguard's fund, but you are paying occasional (or even no fees) for trading. If you have over $1M, Vanguard gives you free trades each year.
3) Note that the equalweight strategy has done well for about the same period of time that wealthfront's analysis is using (weird that they would use those favorable numbers). If you look back at the prior decade, equalweighting lagged the cap weighted approach. Other than the possible tax loss harvesting, you can get essentially the same performance as the EQW with the Vanguard Mid Cap Index Fund.

Once the stocks have appreciated, even a significant hit to their price is unlikely to result in a large enough drop to fall below what you paid for it. And if you plan to have a small income in retirement (like many here do), the longterm benefit of loss harvesting will be substantially limited. Note that wealthfront uses a very high earning couple in California as their example for tax loss harvesting purposes (weird that they would use the most favorable scenario to their analysis).
I think the benefits of doing this are questionable, and the downside is seriously complicated taxes and a lot of tracking error from the cap weighted index. I would consider doing it myself (buying the stock myself and not wealthfront doing it) when I had the money, but I'd have to really believe in the strategy. Not sure I do at this point.
