Re: I think Roths should be in stocks
unclemick,
The conventional IRAs are in Tweedy, Browne Global Value (TBGVX) since that's the least tax-efficient of our funds. When we convert we'll have Tweedy roll shares from the conventional IRA accounts to Roths. Same shares, same company, different account numbers, much better tax treatment.
When spouse quits part-time work, we'll drop down into the 10% tax bracket for about 10 years where our only income will be my pension & our investment income. When her pension kicks in, we'll be back in a higher tax bracket. So we're taking advantage of that decade's lower bracket to "prepay" now to avoid a much more taxing situation later. Who knows what taxes will look like in the future, but I'd be very surprised if they're lower!
I treat my govt pension (and eventually, spouse's pension) as the income from an equivalent portfolio of T-bills. (Perhaps that could be TIPS since the pension has a COLA, but my point is that it's all bonds.) So our retirement portfolio is 100% equities (BRK.B, TBGVX, plus iShares S&P600/Barra Small-cap Growth ETF IJT, and the Dow Jones dividend ETF DVY). We also keep two years' expenses in cash.
We'll be paying the IRA conversion tax out of taxable investments, so the new Roths will start at the same balance as the old conventional IRAs. A poster at Ed Slott's irahelp.com board pointed out: "There is a huge benefit to Roth conversions that is largely understated and not usually addressed directly. If the client converts and pays the tax from 'other funds', as a practical matter the client has just contributed a 'fresh' amount (the tax payment) directly to a Roth. This is an otherwise impossible thing to do!"
That's the "going in" strategy. And you're right, the conversion will compound for a very long time since Roths don't need a "taking out" strategy. Our grandparents all lived well into their 90s so spouse and I are expecting to hit triple digits. I don't know what future returns will bring, but if we're going to be compounding for 50+ years then we'll keep our IRAs in value stocks.
