Life Cycle Asset Allocation
Friday, August 31st, 2007Life cycle asset allocation mutual funds are increasingly popular among those seeking single fund, buy it and forget it investment solutions.
Right now the retirement target date funds are essentially the domain of mutual funds, but it is just a matter of time before they are also the domain of ETFs.
We have a number of substantial misgivings about the approach based primarily on the complete absence of investor specific information other than retirement date.
For example, what a 50 year old retiree should do is probably different than what a 65 year old retiree should do. What a wealthy retiree and a struggling retiree should do is completely different. What a retiree with a pension income should do is not the same as what a retiree without a pension income should do. How one retiree can cope emotionally with volatility is not the same as how another can cope.
Our concerns notwithstanding, we think it is useful to be aware of the allocation models used by leading mutual fund companies in their retirement target date funds. Assuming that those funds represent conventional, “cookie cutter” thinking, it is good to know how your portfolio allocation compares to a ”one size fits all” approach to portfolio design driven soley by age or retirment date.
We reviewed the recommendations and actual fund allocations at T.Rowe Price, Vanguard and Fideltiy to produce the following composite average allocations by target retirement date (and implied current investor age based on an age 65 retirement).
The three organizations are reasonably tightly clustered, but T.Rowe Price is the more aggressive. Vanguard is the more conservative. Fidelity is in between.
One notable observation is that the domestic stock to foreign stock allocation in all of the portfolios is quite different than the actual world market capitalization. The current U.S. stock markets are about 45% of world market capitalization, with the non-U.S. markets representing about 55% of world market capitalization — roughly a 1:1 ratio of U.S. to non-U.S. equities.
The average target date fund allocation within equities is between 3:1 and 4:1, U.S. to non-U.S. equities.
If you seek strong foreign exposures, you would not rely on the allocations used by the target date funds. If you seek only mild foreign equity exposure, target date fund allocations may or may not be appropriate starting points for thinking about your asset allocation.
If you want to absolutely minimize the complexity of your portfolio without squeezing yourself into a ”one-size-fits-all” fund solution, while at the same time maximizing diversification; and if you are happy with only a three asset class approach, you could develop your own reasonably suitable allocation using:
- VTI (to track DJ Wilshire 5000) for domestic stocks
- VEU (to track FTSE World ex US) for non-domestic stocks
- BND or AGG (to track Lehman Aggregate) for domestic bonds
- your money market fund of choice
Of course, you may might rather have additional classes in your portfolio, such as real assets and commodities and foreign bonds, for example. And you might prefer to be more granular in some of the classes — one example being foreign developed country stocks and foreign emerging country stocks for your non-domestic equities.
In any event, there is more than age and retirement date to consider in portfolio design and asset allocation. We certainly design portfolios with more investor needs and circumstances in mind, as other thoughtful investment advisors would also do.
