Multi-account management + asset location.

Most retail traders have one trading account and stop there. Real wealth accumulates across multiple accounts — taxable brokerage, traditional IRA, Roth IRA, 401(k), HSA, and possibly an SEP IRA or solo 401(k) for self-employed income. The framework treats each as a separate sleeve allocation but with one critical addition: asset location. The same Sports Cars name belongs in different accounts depending on its tax treatment. Same dollar amount, same conviction — different account choice can swing after-tax returns by 1-3% annually. This is the most boring lesson in the curriculum and probably has the largest dollar impact for traders with multi-account setups.

The asset-location framework

Tax-efficient assets go in taxable accounts (broad index ETFs, low-turnover holdings, qualified dividends). Tax-inefficient assets go in tax-advantaged accounts (REITs paying ordinary dividends, high-turnover trading, short-term holdings, taxable bonds). Roth accounts get the highest-expected-return assets because future growth is tax-free. This three-bucket logic optimizes after-tax compounding.

Account typeTax treatmentBest assets
Taxable brokerageRealized gains taxable; qualified dividends 15-20%Index ETFs, long-hold positions, qualified-dividend payers
Traditional IRA / 401(k)Tax-deferred; ordinary income at withdrawalREITs, taxable bonds, high-turnover trading, short-term holdings
Roth IRA / Roth 401(k)Tax-free at withdrawalHighest-expected-return assets — Sports Cars, growth names, options
HSA (if available)Triple tax-advantaged (deductible + grows tax-free + tax-free for medical)Treat as Roth-equivalent if not used for current medical expenses

What this means for the Sports Cars sleeve

From Lesson 13: Sports Cars hold high-conviction concentrated growth names (NVDA, GOOGL, AVGO, etc.) at 12-18% per name. These are the highest-expected-return positions in the portfolio. Asset-location logic says: put them in Roth accounts first. A 15% NVDA position in Roth captures all the upside tax-free. The same position in taxable owes tax on gains and on dividends. Same trade, materially different after-tax outcome.

Constraint: Roth space is limited (annual contribution caps). The trader fills Roth with Sports Cars first, then traditional IRA, then taxable as overflow. Anchors and HCF (Lesson 13) — lower-return positions — go in taxable where the tax drag is smaller in absolute terms.

$40K Roth → fill with Sports Cars (highest growth, tax-free at withdrawal). $120K Traditional → high-turnover + REITs (tax-deferred handles ordinary-income drag). $80K Taxable → indexes + Anchors (qualified dividends + minimal turnover). Estimated savings vs. uniform allocation: ~1.4% / yr after-tax. Compounds materially over 20+ year horizons.
Rebalance the slider mix — the recommended placement adapts. Constraint: Roth fills first with Sports Cars, then Traditional with high-turnover, then Taxable absorbs the rest. The framework's Premium portfolio-switcher implements this logic.

The framework's Premium portfolio-switcher

The Premium-tier feature lets the user switch between portfolios (one per account). The dashboard surfaces:

The 13 risk pillars compose across accounts, not per-account. A 12% NVDA in Roth + 6% NVDA in taxable = 18% effective NVDA — at the per-name cap. The framework reads aggregate exposure even though the positions sit in different brokerage accounts.

What doesn't change

Asset location is about where a position lives, not whether to take it. Every position still passes the 13-pillar gate, the broker pre-flight chain, the sector cap, the drawdown gate, etc. The asset-location decision happens after the trade is approved — it's a placement question, not a quality question. A trade that fails the audit doesn't become tradeable because Roth space is available.

Wash sales — taxable account specific

The IRS wash-sale rule disallows a loss if you re-buy a "substantially identical" security within 30 days. Only applies in taxable accounts; tax-advantaged accounts ignore wash-sale (gains/losses there don't matter for current taxes anyway). Operational implication: trim a losing position in taxable, can't re-enter for 30 days without losing the loss harvest. The framework flags this in the Trade Journal — hasWash field on the position card; the basis-display shifts to "adjusted basis" once a wash event is detected.

The real lesson

One account is the simple case. Multiple accounts compound across 20-30 years and the asset-location decision swings after-tax returns 1-3% annually. Highest-expected-return assets go in Roth; tax-inefficient income goes in Traditional; everything else goes in Taxable. The 13 risk pillars compose across accounts, not per-account. The framework's Premium portfolio-switcher implements this; the trader's job is to fill Roth first with Sports Cars, then Traditional, then Taxable. Boring discipline, large dollar impact.
