About

A daily market-timing rule: if gold miners show stronger 1‑week momentum than copper miners, buy SPY; otherwise sit in T‑bills (BIL). Uses a 5‑day RSI signal from GDX vs COPX. Creator notes it doesn’t work well.
NutHow it works
Each day, compare 5‑day “strength scores” (RSI) for two miner ETFs: GDX (gold miners) vs COPX (copper miners). If GDX’s score is higher, invest 100% in SPY (U.S. large‑cap stocks). Otherwise, hold BIL (short‑term T‑bills; cash‑like). Rebalance daily.
CheckmarkValue prop
Out-of-sample: beta ~0.76, annualized return 8.83%, Sharpe 0.63, max drawdown ~18.4%. While below SPY's 15.8% return, it offers lower beta and defined risk control—a defensive, diversification tool vs the S&P 500.

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.
