The Vanguard Lifestrategy funds can really simplify investing, if you like the asset allocation. For me, the advantages are:
- They rebalance it.
- There is no need for us to touch it at all.
- I have less temptation to mess around with it.
But the expense ratio is a bit high. Vanguard sets it as the weighted average of the underlying funds using investor class funds, not admiral. For the 80/20 growth fund VASGX that comes to 0.14%. The weighted average of the components using ETFs is 0.06%. $800/year saving on $1M. Not a lot, but if we're trying to optimize...
I wondered how the expense ratio affected performance. Here's what I got from Porfoliovisualizer:
July 2013 - March 2019 CAGR (July 2013 when BNDX data available)
VASGX
8.44%
Component ETFs (VTI, VXUS, BND, BNDX)
Rebalance Annually 8.39%
Rebalance Quarterly 8.37%
Rebalance Monthly 8.36%
Different start times will give different results, depending on if the constant rebalancing helps or not, but it looks like the extra expense of Lifestrategy might not hurt much, if at all.
