About

Mostly stays 100% in SPY. It briefly switches to long‑term Treasuries (TLT) only after SPY has had ~9 straight up days with virtually no dip. Daily check, all‑or‑nothing allocation.
NutHow it works
Every day it looks at SPY’s biggest drop from any recent high over the last 9 trading days (its “max drawdown”). If that drop is essentially zero—meaning SPY rose for ~9 days without a dip—it moves 100% into TLT (long‑term U.S. Treasuries). Otherwise it holds 100% SPY. It rechecks daily.
CheckmarkValue prop
Out-of-sample, this strategy offers strong risk-adjusted performance (Sharpe ~1.30; Calmar ~1.13) with SPY-like drawdowns. A simple daily, rules-based rotation into Treasuries provides steadier risk-adjusted results versus SPY alone.

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.
