Episode 343 - How to Choose an Asset Allocation

Episode Summary

Executive Summary: The episode centers on how to choose an asset allocation by balancing behavioral loss tolerance, ability to take risk, and need to take risk, while emphasizing that risk is not just downside volatility. The hosts also address community controversy over return stacking, explain the PWL-OneDigital acquisition, and share a personal health update from Ben that reframes the importance of health over money.

Main Topics: Choosing an asset allocation via risk profiling (Priority: 5/5): The hosts frame portfolio choice as the interaction of behavioral loss tolerance, ability to take risk, and need to take risk, using John Grable’s framework to explain how investors should determine appropriate equity exposure. Behavioral loss tolerance and risk composure (Priority: 5/5): A large portion of the discussion focuses on how investors actually behave during market stress, why questionnaire-based risk tolerance is imperfect, and why many people overestimate how much volatility they can handle. Risk-taking ability and financial capacity (Priority: 4/5): They explain that liquidity needs, time horizon, income stability, human capital, insurance, and existing assets determine whether an investor can afford to take risk without jeopardizing lifestyle or goals. Need to take risk vs. desire to take risk (Priority: 4/5): The hosts argue that investors should generally take only as much risk as needed to achieve goals, because taking extra uncompensated risk adds stress without adding utility unless the goal truly requires it. Risk beyond short-term volatility (Priority: 4/5): The episode challenges the industry habit of defining risk only as volatility, noting that long-horizon investors face different dynamics, including mean reversion in stocks and inflation risk in nominal bonds. AMA controversy and optimization trade-offs (Priority: 3/5): The after-show addresses listener criticism that the hosts were dismissive of optimization and return stacking, clarifying that they were skeptical of trade-offs and not ignoring obvious expected-return opportunities. OneDigital acquisition and personal health update (Priority: 5/5): The hosts discuss reactions to PWL’s acquisition by OneDigital, explaining the strategic rationale, continuity of the podcast and culture, and Ben’s surgery for a potentially cancerous testicle, which underscored the importance of health.

Key Arguments: Behavioral loss tolerance is often the binding constraint on asset allocation because a portfolio that is theoretically optimal is useless if an investor cannot stick with it during crashes. Ability to take risk depends on practical factors like time horizon, liquidity needs, income stability, insurance, and human capital—not just net worth. Need to take risk should be minimized: if goals can be met with lower expected-return assets, taking more risk often only adds volatility and stress. Risk questionnaires measure relative risk tolerance, but the score must still be mapped by an advisor to a portfolio; a high score does not automatically mean 100% equities. People routinely overestimate their risk tolerance, especially men, younger respondents, and those with graduate education; actual market behavior often differs from survey answers. Stocks may be safer than bonds for long-horizon, inflation-adjusted goals because of mean reversion/serial dependence in stock returns and inflation vulnerability in nominal bonds. Investors who want more return should prefer compensated risks like higher equity allocation, factor tilts, or leverage over uncompensated risks like concentrated stock bets or sector bets. The hosts were not rejecting return stacking out of apathy; they argued that the expected benefit likely did not justify added complexity, tracking error, cost, or behavioral risk for their clients. PWL’s acquisition by OneDigital was presented as a strategic partnership to improve technology, scale, succession, and revenue stability—not a cut-cost or culture-change move. Ben’s health scare reinforced the theme that financial planning should support life and well-being, not distract from them.

Data Points: Podcast episode number: 343 - The episode is introduced as episode 343 of the Rational Reminder Podcast.

Recommended equity range for high risk tolerance at PWL: 70% to 100% stocks - The hosts say their risk profiler maps high psychometric risk tolerance to portfolios in this range, adjusted by other constraints. Low-ability-to-take-risk example: Less than 5 years; 5%+ annual withdrawals; no other assets/income - Grable’s framework is cited to illustrate a low capacity to take risk. High-ability-to-take-risk example: 10+ year horizon; no liquidity needs; other assets/income available - Grable’s framework is cited to illustrate a high capacity to take risk. CFA Institute study equity allocation: 20% at 1-year horizon; 50% at 20-year horizon - A 2024 CFA Institute paper is referenced to show that longer horizons justify higher equity allocations in their model. Comment thread size: 119 comments - The AMA controversy and discussion around return stacking is noted as having generated 119 comments. OneDigital customer/organizational scale detail: 52 software developers - Used to illustrate OneDigital’s investment in technology and client-experience capabilities. Review count milestone: 666 to 667 reviews - A listener joked about the podcast sitting at 666 reviews after the acquisition news, and the team noted it had moved to 667.

Pivotal Quotes: "You should take as much risk as you need to, but no more." — Mark McGrath: Used to summarize the philosophy of balancing goal achievement against unnecessary portfolio volatility. "If you’re really stressed out about your portfolio after a market decline, you’ve learned something really valuable about yourself." — Ben Felix quoting Ken French: A point about changing portfolio risk after actually experiencing drawdowns, rather than after markets recover. "We’re not going to become a private equity mouthpiece." — Ben Felix: A direct reassurance to listeners concerned that the OneDigital acquisition would compromise the podcast or firm’s investment views.

Implications: Listeners should focus on portfolios they can actually hold, not just portfolios that look optimal on paper. The episode also signals continuity at PWL under OneDigital, while reminding investors that health, behavior, and goals matter more than theoretical optimization.
