Episode 281: Lifecycle Asset Allocation, and Retiring Successfully with Justin King

Episode Summary

Executive Summary: In episode 281 of the Rational Reminder Podcast, hosts Benjamin Felix and Cameron Passmore challenge traditional lifecycle asset allocation advice, presenting evidence from Scott Cederberg's new paper that suggests an all-equity portfolio (50% domestic, 50% international stocks) may outperform balanced or age-based strategies across accumulation, consumption, and bequest objectives. The episode also features Mark discussing insurance ownership in corporations, a book review with Justin King on retirement planning, and a look back at Dr. Anna Lemke's insights on dopamine.

Main Topics: Lifecycle Asset Allocation Critique (Priority: 5/5): Benjamin Felix presents Scott Cederberg's paper challenging the conventional wisdom of shifting to bonds with age, arguing that an all-stock portfolio (50% domestic, 50% international) dominates target-date funds and balanced portfolios on wealth, consumption, and bequest metrics, even in left-tail outcomes. Insurance Ownership in Corporations (Priority: 4/5): Mark explains the tax and strategic considerations for holding life, disability, and critical illness insurance personally versus inside a corporation, emphasizing the trade-offs between pre-tax premium payments and tax treatment of benefits. Retirement Planning with Justin King (Priority: 4/5): Justin King discusses his book 'The Retirement Cafe Handbook,' focusing on nine accelerators for a successful retirement, including redefining retirement, purpose, health, and planning for longevity, with an emphasis on thriving rather than just drifting. Dopamine and Financial Decisions (Priority: 3/5): A look back at episode 177 with Dr. Anna Lemke, exploring how dopamine drives addictive behaviors and impacts long-term financial decision-making, suggesting that investing in stocks may feel more like gambling in a dopamine-rich world. Behavioral Constraints in Investing (Priority: 3/5): Benjamin Felix highlights the behavior gap—investors' tendency to make poor timing decisions—which can erode returns by 1.5-2% annually, especially in volatile assets, and the role of financial advisors in mitigating this.

Key Arguments: Traditional lifecycle advice to shift to bonds with age is based on flawed assumptions about volatility as risk; for long-term investors, volatility is less important than the probability of meeting consumption goals. Empirical evidence from a 2,500-year dataset shows that a 50% domestic, 50% international stock portfolio outperforms target-date funds and balanced portfolios on mean, median, and 10th percentile outcomes for wealth, consumption, and bequest. Adding even 5-10% bonds to an all-stock portfolio reduces performance on all metrics considered, challenging the diversification benefit of bonds for long-term investors. Government pensions (e.g., CPP) act as a risk-free asset, reducing the need for bonds in a market portfolio, as they provide inflation-indexed annuities. For insurance in corporations: life insurance is best owned corporately for tax efficiency, disability insurance is best owned personally to keep benefits tax-free, and critical illness insurance depends on whether the payout is needed personally or by the business. Retirement success requires more than financial planning; it involves purpose, health, social connections, and planning for longevity, as outlined in Justin King's nine accelerators.

Data Points: Required savings rate for equivalent retirement utility: 7.2% - Switching from a target-date fund to a 50/50 domestic/international stock portfolio reduces the required savings rate from 10% to 7.2% for the same retirement utility. Required savings rate for cash allocation: 50% - Investing 100% in cash requires saving 50% of income to achieve the same retirement utility as a target-date fund with 10% savings. Behavior gap in equities: 1.5-2% - Investors lose approximately 1.5-2% annually due to poor timing decisions, with the gap increasing for more volatile assets. CPP contribution rate (2024): 11.9% - In Canada, 11.9% of the first $68,500 in salary goes to CPP contributions, designed to replace 25% of pensionable earnings (increasing to 33% by 2064). Optimal domestic stock weight for non-US investors: 35% - Reducing domestic stock weight from 50% to 35% in the all-stock portfolio produced small performance improvements, but further reductions hurt outcomes.

Pivotal Quotes: "The all-stock portfolios also dominate the other asset allocation strategies on the bequest amount on average, and again, in the left tail. So, right through the life cycle, accumulation, consumption, bequest. An all-stock portfolio dominates a portfolio with some bonds in it." — Benjamin Felix: Summarizing the key finding from Scott Cederberg's paper that all-equity portfolios outperform those with bonds across all lifecycle stages. "If you were writing yourself into that wonderful movie of an amazing retirement, what would that hero do?" — Justin King: Encouraging listeners to proactively design their retirement with purpose and optimism, rather than drifting into it. "The all stock portfolios have much bigger drawdowns than bigger drawdowns. I don't know if much probably isn't fair, but the average drawdown in the stock portfolio is larger than it is in the balanced or the target date or the other alternatives. That's a real consideration because people do struggle with volatility and they do struggle with drawdown." — Benjamin Felix: Acknowledging the behavioral challenge of all-equity portfolios despite their superior long-term outcomes.

Implications: Listeners should reconsider traditional glide-path asset allocation, as all-equity portfolios may offer better long-term outcomes despite higher volatility. Behavioral discipline and advisor trust are critical to avoid costly timing errors. Insurance ownership decisions should be tailored to tax and liquidity needs. Retirement planning must integrate purpose, health, and longevity considerations beyond finances.
