About

A monthly, equal-weight trend strategy: hold SPY, QQQ, and IWM only if their last ~30 trading days averaged a gain; otherwise park each sleeve in Treasuries (BIL or IEF) to reduce losses during downtrends.
NutHow it works
Each month, split money into three equal parts. For each part, check if the last ~30 trading days for SPY, QQQ, or IWM have, on average, gained. If yes, own that stock ETF. If not, switch that part to safety: BIL (T‑bills) for SPY/IWM, IEF (7–10y Treasuries) for QQQ. Repeat monthly.
CheckmarkValue prop
Out-of-sample edge: ~32% annualized return vs ~29% for the S&P, higher Sharpe (~2.44 vs ~1.41), notably lower drawdown (6.82% vs 13.73%), and strong Calmar (~4.69). A monthly trend-following mix that preserves upside and cuts losses.

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.
