Q: What should go in a Roth vs. a Traditional IRA?

In 30 seconds: Put the most aggressive, fastest-growing assets (QLD, QQQ) in the tax-free Roth IRA, and the conservative ones (BOXX, QQQI, cash) in the Traditional IRA or a taxable account. That way the most tax-advantaged room goes to the assets that grow the most. The pairing trick: one dollar of QLD in Roth against one dollar of BOXX (cash) in the Traditional account keeps overall Beta at 1.0 — account location decides “which asset enjoys the tax break,” without changing overall risk.¹

Situational variants (how people actually ask it)

• “My Roth IRA holds BOXX and QQQI — is that paired right?”
• “I’m doing a Roth conversion of $200k — which asset should I move in, and what do I buy after?”
• “Should a high-dividend fund like QQQI go in the Roth or the Traditional account?”

Principle: aggressive into Roth, conservative in Traditional/taxable

Growth in a Roth is tax-free for life, so stuff the “will grow the most” assets in there to let the biggest gains come out untaxed; the Traditional IRA is taxed on withdrawal, so it suits conservative, low-growth positions.¹

• Roth: QLD (2× QQQ), QQQ — most aggressive. “You’d rather hold all BOXX in the Traditional account and all QLD in the Roth.”
• Traditional IRA / taxable: BOXX, QQQI, cash — conservative, cash-flow-producing, or safety-cushion positions.
• Neither QQQI nor BOXX should go in the Roth; the most conservative thing in a Roth should still be QQQ.

Use “pairing” to keep overall Beta

Don’t look at each account’s allocation in isolation — look at the whole. Pair the two sides: one dollar of QLD (Beta 2.0) in Roth against one dollar of BOXX (Beta 0) in the Traditional account → combined Beta 1.0, the risk of one dollar of QQQ, but with all the growth in the tax-free Roth.¹

Look at how much is in the Roth first to size the QLD:¹

• E.g. Roth has $200k → all QLD; Traditional holds a matching $200k of BOXX; put any remainder in QQQ.
• If the Roth is far larger than the Traditional (e.g. Roth $3M, Traditional $1M) → the Roth might become $1M QLD + $1M QQQ + $1M cash, with the Traditional’s $1M all cash. Unless the Roth is larger than the Traditional, the Roth shouldn’t hold cash.
• If your Roth is still small: it should be all QLD.

Note: James’s own bespoke setup is — the brokerage account holds almost no cash, fully invested, generating cash flow via stock pledge; the cash sits in the Traditional and Roth accounts. That’s his personal approach, not a general rule.¹
