About

A simple, passive, one-fund portfolio: 100% VOO (Vanguard S&P 500). It owns the 500 largest U.S. companies. Rebalanced once a year. Low cost and diversified across big U.S. stocks, but fully exposed to stock market ups and downs.
NutHow it works
It holds one fund: Vanguard S&P 500 ETF (VOO). That fund owns the 500 biggest U.S. companies. The portfolio stays 100% in VOO at all times—no timing or signals. Once a year, it’s reset to 100% VOO to reinvest dividends and correct small drifts.
CheckmarkValue prop
Out-of-sample, this 100% VOO strategy beats the S&P on risk-adjusted terms: Sharpe ~1.905 vs ~1.880, similar max drawdowns (~5%), and a small annualized edge (23.45% vs 23.29%). Simple, low-cost, single-ETF exposure.

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.
