Chapter Summaries

Chapter 1: Planning for the Unknowable — Managing Risk in an Uncertain World

Ben and Bill open with a philosophical question from listener Richard: if you can’t see what’s coming, how do you build a financial plan? Ben references a 2001 DoD memo by Lynn Wells that walked through the major unpredictable events of each decade of the 20th century, concluding that the future will always look different than we expect — written just months before 9/11. The current decade has delivered COVID, supply chain shocks, 9% inflation, the fastest market crash and recovery in history, and AI. The answer: you cannot predict, but you can prepare. Build a portfolio durable enough to handle a wide range of outcomes — inflation, deflation, bull markets, bear markets — without needing to predict which comes first. Howard Marks’s axiom: “You cannot predict but you can prepare.” The key distinction is between the possible (nuclear war, market to zero) and the probable. You build a plan for the probable, not every tail scenario.

Chapter 2: Mega Backdoor Roth Question — Is It Worth Paying Tax Now to Shift Assets?

Rachel (early 40s) and her husband have $1M pre-tax, $1M Roth, $500K taxable brokerage. Her employer now allows after-tax contributions and in-plan Roth conversions (mega backdoor Roth). To maximize contributions, they’d go cash-flow negative, drawing $1,000/month from the taxable account, triggering 15% capital gains on the ~35% appreciated assets. Her husband prefers to limit contributions and preserve the taxable account. Ben and Bill both side with the husband. The trade-off: for the low cost of 15% capital gains now, you get 50+ years of tax-free compounding — mathematically compelling. But the complexity and the cash-flow hit make this a close call. The most important thing is to have a plan at all. Their existing tax diversification (40% pre-tax / 40% Roth / 20% taxable) is already excellent, which reduces the urgency of the conversion.

Chapter 3: BOXX ETF — A Tax-Efficient Alternative to Money Market Funds

Curtis asks about the Alpha Architect BOXX ETF (ticker: BOXX) as a money market alternative. BOXX uses a “box spread” options strategy (simultaneous long call / short put positions that offset) to replicate a T-bill-like return without paying dividends. Instead of receiving ordinary income distributions (taxed at your marginal rate, as with BIL or money market funds), the fund’s NAV ticks up daily and you pay capital gains when you sell — and under IRS 1256 contract rules, that gain is treated as 60% long-term / 40% short-term regardless of how long you held. Additional benefit: you can defer the gain until you actually sell. For high earners, the tax equivalent yield advantage over T-bill funds can be significant. Caveats: relatively new fund (launched early 2023); unsettled tax math (consult CPA on whether gains must be marked-to-market annually or can be deferred); and unlike direct Treasury interest, the income may not be exempt from state taxes.

Chapter 4: 529 Account for Career Reboot at Age 48 — Useful But Not a Divorce Shield

Carrie is a single mom facing divorce, planning to go back to school at 48 to re-enter the workforce after a career as a magazine writer/editor. She asks whether a 529 can shield assets from divorce proceedings and provide a tax-advantaged way to fund her education. Answer on the divorce angle: unfortunately not reliably — any asset you control is generally subject to court proceedings (not legal advice; consult an attorney). However, the 529 is still a strong tool for her situation: many states offer a state income tax deduction on contributions (e.g., New York allows $10K/year). If she builds it up over 2-4 years, the assets grow tax-free and withdrawals for qualified education expenses are tax-free. Even a conservative investment inside the 529 (e.g., bond fund) generates tax-sheltered returns. Bill and Ben are both enthusiastic about the career reboot itself: adults going back to school take it far more seriously than 18-year-olds, and psychology in particular is highlighted as underrated and broadly applicable.

Chapter 5: Alternative Assets — Is 40% Illiquid Too Much?

Jeremiah (mid-40s, 10 years from retirement) has ~40% of investable assets in private equity, venture capital, private real estate, private credit, and other alternatives — a mix of semi-liquid and fully illiquid. Bill and Ben both flag this as very high. The endowment/pension comparison doesn’t hold for individual investors: endowments have infinite time horizons, no tax reporting headaches, and no personal liquidity needs. For an individual approaching retirement, the downsides compound: (1) K-1 tax reporting is complex, often arrives after the April deadline, and can produce surprise short-term capital gains; (2) fees are high and typically consume any alpha; (3) illiquid positions can’t be exited on your schedule; (4) you learn the most about a fund when you try to get out of it — not going in. Bill’s recommendation: get to 10% or less. Ben’s two-rule framework: (1) fund managers charge premiums that usually absorb whatever alpha they generate; (2) if you’re seeking an illiquidity premium, you can access smaller/microcap public equities with similar risk characteristics at much lower cost and complexity. For Jeremiah: have a direct conversation with your advisor about the liquidity runway as retirement approaches.

Most important take away

The core investment principle of this episode is “you cannot predict but you can prepare” — the future is irreducibly uncertain, so the answer is not to forecast more accurately but to build a portfolio and financial plan durable enough to survive a wide range of outcomes without needing to know which one comes first. The second most actionable takeaway for most listeners is the BOXX ETF discussion: for cash or short-duration positions in taxable accounts, replacing T-bill funds with a box-spread ETF like BOXX can meaningfully improve after-tax returns at high income levels by converting ordinary income into deferred, partially long-term capital gains — a low-complexity structural improvement worth understanding.

Summary

Investments and Products Mentioned:

• BOXX ETF (Alpha Architect) — Box spread options strategy replicating T-bill returns with capital gains tax treatment instead of ordinary income dividends. 60/40 long-term/short-term capital gains under IRS 1256 rules. Potential state tax exemption loss vs. direct Treasuries. Discussed favorably for taxable accounts; especially useful for high earners.
• BIL ETF (State Street 1-3 Month T-Bill) — Used as the benchmark comparison for BOXX. Ordinary income distributions monthly/quarterly. Referenced as the conventional alternative.
• Private Equity, Venture Capital, Private Real Estate, Private Credit — Jeremiah’s 40% allocation. K-1 reporting, high fees, illiquidity, tax complexity all flagged as significant downsides for individual investors. Both hosts recommend reducing to 10% or less.
• Mega Backdoor Roth — After-tax 401(k) contributions + in-plan Roth conversion. Mathematically compelling for Rachel’s situation (50+ years tax-free compounding for 15% capital gains cost today) but adds complexity and cash-flow strain. Both hosts lean toward keeping it simpler.
• 529 College Savings Account — Useful for Carrie’s career reboot: state tax deduction on contributions + tax-free growth + tax-free qualified withdrawals. Recommended despite not being a divorce shield.
• Public.com — Show sponsor; generates custom AI-built thematic indexes as investable products.

Actionable Insights:

1. Build for durability, not prediction. You can’t know when inflation, deflation, recessions, or bull markets will arrive. Build a portfolio that survives each without requiring the correct forecast. Howard Marks: “You cannot predict but you can prepare.”

2. Consider BOXX ETF for taxable cash/short-duration positions. If you hold T-bill funds or money markets in a taxable account and are in a high tax bracket, BOXX (or similar box-spread ETFs) converts ordinary income into deferred, partially long-term capital gains. Consult a CPA for K-1/1256 specifics and verify state tax treatment.

3. Mega backdoor Roth is most valuable when you don’t have to sell appreciated taxable assets to fund it. If doing so creates cash-flow pressure and capital gains drag, the complexity may not be worth it — especially if your tax diversification is already solid.

4. Trim alternative assets to 10% or less if you’re approaching retirement. The endowment model doesn’t translate to personal finance: individuals have tax obligations, liquidity needs, and finite time horizons that make 30-40% illiquid allocations genuinely risky. K-1 reporting complexity and fee drag further erode the case.

5. 529s work for adult career reboots too. State income tax deduction on contributions + tax-free growth is a real benefit even if the account is only open for 2-4 years. Not a divorce protection tool, but a legitimate tax-advantaged vehicle for re-education.

6. Simple beats complex as a default. Multiple answers in this episode converge on the same principle: a mediocre plan you execute beats a sophisticated plan you don’t fully understand. If complexity requires a lot of explanation to justify, that’s a flag.
