Re: Rule of Thumb
The rule of thumb that I use is to put the investments that generate the greatest annual tax liability into the tax deferred accounts.
That means you want to shelter income that's not 15% income first and foremost. Generally, this includes most bond income including TIPs, income from CDs, the bulk of REIT distributions, income from commodity funds, and some foreign dividends.
After that (if you still can allocate more in your tax deferred accounts), you could start layering in funds that throw off large distributions like actively managed stock funds and most value funds. Keep in mind that although you get to defer the income, when you do make withdrawals from these accounts (except ROTH), you'll generally pay tax at your ordinary income tax rate instead of the reduced 15% rate.
So for me the split looks like this:
Total Bond Market, TIPS, REITs, Pimco commodity (PCRIX), Gold ETF, Value index fund (left over from when dividends were taxed at ord. income rate).
Growth index, emerging market idx, pac rim index, european idx, tax-emempt bonds, some CDs for liquiidity.
That's basically how I did and it seems to be making sense. .Maybe others can chime in with something I've missed or mischaracterized....
