I'm not getting something, and I hope you folks can straighten me out.
The Holy Trinity of Bogle-ism seems to be Asset Allocation, Rebalancing, and Asset Location. I've read the wiki on Asset Location, and understand the advantage of stuffing tax inefficient investments into an IRA.
What I don't get is this: If you have a tax-advantaged account stuffed with only tax inefficient investments(let's say it's VBMFX), and a taxable account full of only tax efficient investments(call it VTSMX), ..... how can you re-balance? Doesn't that get messy? Is it even possible?
I've read threads here where some folks admit they have TSM in a Roth IRA, then they get blasted by the group (well, mildly chided, anyway) for having Total Stock Market in a tax-advantaged account. My take-away from these types of threads (and maybe this is my mistake), is that some of the true Bogleheads have nothing but FI investments in their IRA's.
As an example: Taxable account A is all TSM, and 70% of a portfoilio. IRA account B is all Total Bond Market, and 30% of a portfolio. If stocks fall 20% and bonds go up 5%, you now have a 64/36 AA. How do you rebalance that?
I don't get it. What am I missing?
