Let's assume for the sake of discussion that you are planning for 30 years, that each fund would be of roughly equal size and would withdraw 3-4%/year, you would own the following:

Target Retirement 2015
-- 55/45 Stocks/Bonds
Target Retirement 2025
-- 71/29 Stocks/Bonds
Target Retirement 2035
-- 86/14 Stocks/Bonds
Investing 1/3 of the portfolio in each, you are holding 71/29 Stocks/Bonds.
- Code: Select all
Portfolio $100k $100k $100k $300k
Stocks 55 71 86 71
Bonds 45 29 14 29
- Unless one piece (or more) is invested for a different purpose and timeframe, there is absolutely NO benefit in splitting 3 ways.
- I may understand, for instance, 2/3 invested in TR 20XX based on Ability and Need for risk to withdraw for retirement; and 1/3 invested in TR 20XX for kids, charity, whatever.
- Otherwise, for your own retirement, I say hold TR 2025 and call it a day!
The years chosen were arbitrary could have easily been 10, 15, 20. The point here is that you have greater control over withdrawals with one of the upsides being a longer timeframe for stocks to grow. This is a basic 3 bucket approach
How would your proposal be better than buying the underlying ETFs in the preferred proportions and then simply mentally accounting for each of the ETFs as three separate 'accounts'
Example your total position in BND is 300K but the mental accounting model [you can make a spreadsheet to visualize this while you're at it] views the BND allocation as:
BND 1 - 100K
BND 2 - 100K
BND 3 - 100K
Based on the mental accounting model you have control of what you withdraw from. You have more control of your AA via your withdraw methods and you can implement your own rebalance & TLH sceme if you want to.
I'm by no means advocating this or any other form of mental accounting but if someone is determined to do it how would this not be an improvement?
Also - I don't think you have as much control withdrawing from your proposal because you only choose which proportions of the underlying each withdrawn dollar represent. You can't pull just from bonds or just from TSM, etc.
I must be missing something....
