A client with $25 million asks two questions over coffee: "What should I own?" and "How will I know if it's working?" The first answer flows from goals, constraints, and tax lots. The second flows from disciplined reporting against benchmarks the client actually cares about.
A private client portfolio is built from the goals down, not the efficient frontier up. The wealth manager identifies three to five distinct goals, each with its own time horizon, required dollar amount, and tolerance for shortfall.
Each bucket carries a probability threshold. A liquidity bucket is sized so the client has high confidence (often 99%+) that the cash is there when needed. A growth bucket can tolerate 25% or more drawdown because the time horizon repairs it.
Human Capital and Financial Capital. A 45-year-old surgeon with $3 million in financial assets and 20 more earning years has a human capital value (present value of future after-tax earnings) often exceeding $10 million.
Common mistakes
- Benchmarking a goals-based portfolio to a market index. A 60/40 portfolio benchmarked to the S&P 500 will appear to lose in every equity bull market. The correct benchmark is a custom blend of the IPS asset-class weights. Trap: declaring a successful program a failure based on the wrong yardstick.
- Putting MLPs inside an IRA without checking UBTI. REITs are generally fine in IRAs because their dividends are not UBTI. MLPs are not. MLP UBTI above $1,000 inside an IRA triggers trust-rate tax (up to 37%) on the IRA itself. Trap: defaulting all high-yield assets to tax-deferred without screening for UBTI.
- Treating the 4% rule as a guarantee. It is a 95% historical success rate for 30 years in US backtests with a 60/40 portfolio. Longer horizons, lower starting yields, and higher equity valuations cut that rate. Trap: applying 4% to a 40-year horizon at age 55.
Bottom line
- Build allocations from goals-based buckets (liquidity, lifestyle, growth, aspirational) sized by required dollars and time horizon, not one mean-variance frontier.
- Total wealth equals human capital plus financial capital. Bond-like human capital warrants more equity; equity-like human capital warrants less.
- Asset location is the highest-leverage tax move: ordinary-income to tax-deferred, tax-efficient equity to taxable, adding 20 to 75 bps per year at no risk cost.
- The four pillars of taxable-account tax management are tax-loss harvesting, specific-lot identification, charitable gifting of appreciated securities, and step-up at death.
Exam shortcut
Asset-location quick check: ordinary-income and high-turnover assets to tax-deferred; municipals and direct-indexed equity to taxable; highest-growth assets to Roth; never MLPs in an IRA. Roth-conversion window: the years between full retirement and the later of Social Security election or RMD start are the cheapest conversion bracket. If the question shows a low-income gap year, expect Roth conversion to be the right answer.
