About

A Swensen-inspired, low-cost mix of US and international stocks, real estate, short-term Treasuries, and short-term TIPS for broad diversification, inflation protection, and a steadier ride than an all-stock portfolio.
NutHow it works
It splits your money into 5 broad index funds and holds them long term—no market timing. Targets: 30% VTI (whole US stock market), 20% VXUS (stocks outside the US), 20% VNQ (US real estate/REITs), 15% VGSH (short‑term US Treasuries), 15% VTIP (short‑term inflation‑protected Treasuries). Built to balance growth, safety, and inflation defense. Rebalancing isn’t automated here; many rebalance if a slice drifts ~5% from target.
CheckmarkValue prop
Out-of-sample, this strategy offers steadier growth with far lower risk than the S&P 500: max drawdown 8.9% vs 13.7%, Calmar ~2.0, Sharpe ~1.56, beta ~0.56. Diversified, inflation-aware exposure with low turnover.

FAQ

A Composer symphony is an automated trading strategy that executes trades based on parameters of your choice. Some symphonies are similar to holding one ETF in normal conditions and rotating to a different ETF when market conditions shift, for example a 5% drop in the S&P 500, while others use complex rules with dozens of triggers. However, complex doesn’t always mean better. A simple, well-structured symphony can be just as effective as an intricate one. Learn more about how symphonies work here.
