100% allocation to U.S. equities from account opening until the child reaches age 18. Zero allocation to U.S. bonds, Treasuries, corporate debt, or any fixed-income instrument. Zero allocation to non‑U.S. equities, including developed, emerging, or frontier markets. No age‑based glide path or risk‑reduction mechanism as the beneficiary approaches adulthood.
Historical return context
From 1926 to the present, U.S. stocks have averaged approximately 5.5 percentage points per year more than U.S. bonds. Over rolling 10‑year periods since 1926, a 100% U.S. stock portfolio returned about 10.7% annually; a 60/40 U.S. stock / long‑term Treasury portfolio returned about 9.1% annually. The absolute difference between the two averaged 1.6 percentage points per year. Pre‑1926 U.S. data, as well as data from other major global markets, show extended periods – including some 50‑year spans – in which stocks and bonds delivered similar long‑term returns or bonds outperformed stocks. The post‑1926 period is historically exceptional, not a universal constant across time or geography.
Risk‑related trade‑offs
U.S. equities have experienced drawdowns exceeding 40% in multiple decades. With no bond allocation, the account absorbs full market declines without a buffer. A severe downturn occurring when the child is 16 or 17 would not allow a shift to safer assets before funds are withdrawn or used, locking in losses if the market has not recovered. Excluding international stocks eliminates exposure to non‑U.S. growth, non‑dollar earnings, and markets with different valuation cycles, tying performance entirely to a single country’s regulatory, fiscal, and monetary environment. Standard portfolio theory identifies that combining assets with less‑than‑perfect correlation reduces overall portfolio variance without necessarily reducing mean return – a benefit the mandate explicitly prevents.
Horizon considerations
The 18‑year fixed term is long enough historically to recover from most U.S. bear markets, but recovery periods have varied (e.g., 1929–1945, 1966–1982, 2000–2013 for the Nasdaq). There is no provision to adjust allocation based on the child’s intended use of funds – whether for higher education, home purchase, business startup, or retirement – each of which could have different time horizons and risk tolerances.
Structural implications
The policy substitutes an individual family’s asset‑allocation decision with a single statutory rule. It assumes that the long‑term expected return advantage of U.S. equities outweighs the costs of higher volatility and lack of diversification for all beneficiaries, regardless of their specific circumstances. It treats all 18‑year periods as interchangeable, despite historical evidence that long‑run equity performance varies significantly by starting valuation, interest rate environment, and global economic conditions.
Observations from comparative historical data
International stocks outperformed U.S. stocks in the 1970s, 1980s, and 2000s by measurable margins. U.S. bonds outperformed U.S. stocks in several decades, including the 1930s, 1940s, and 2000–2010. The U.S. has been the strongest‑performing major market in recent decades, but extended periods of leadership have reversed in the past across other leading economies (e.g., UK in the 19th century, Japan in the 1980s).
Financial planning perspective
From a risk‑adjusted standpoint, eliminating bonds removes a known volatility reducer. Eliminating international stocks removes a known source of non‑correlated returns. The 1.6‑percentage‑point historical premium of 100% stocks over 60/40 is a realized outcome, not a guaranteed future yield. Whether that premium compensates for the additional drawdown risk and single‑country exposure depends entirely on which future historical period the next 18 years resemble – a matter that historical data does not resolve.
