About

Always 100% in SPY (tracks the S&P 500). No market timing or signals—just pure U.S. large‑cap stock exposure, rebalanced daily to stay fully invested. Simple, passive, and rides the market’s ups and downs.
NutHow it works
It keeps 100% of your money in SPY, an ETF that tracks the S&P 500 (about 500 large U.S. companies). No timing, signals, or cash buffer. It “rebalances” daily, which simply means it stays fully invested in SPY at all times. No leverage.
CheckmarkValue prop
Out-of-sample reliability: ~14.83% annual return, Sharpe ~0.803, max drawdown ~19%, Calmar ~0.79—nearly identical risk/return to SPY. Simple: 100% SPY, no timing, transparent core 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.
