I would really like to see some transparency on these portfolios. It is really hard to find performance data on these funds. Has anyone benchmarked these on their own?
They tend to pick an asset allocation and stick to it (plus some automated whizz-bang stuff like rebalancing or tax-loss harvesting). Once picked, the asset allocation is a bunch of index funds. In general index funds are very good at tracking their benchmark indices.
So it's mostly a question of, do they do a good job of picking asset allocation from the start?
