About

A daily, 15‑sleeve blend that only buys 3× S&P 500 (UPRO) when the S&P 500 is calm and its recent strength score (RSI) is lower than Treasuries (SHY); otherwise it stays in SHY. Equal‑weighted sleeves diversify timeframes and volatility cutoffs.
NutHow it works
What it holds: UPRO (a fund aiming for 3× the S&P 500’s daily move) or SHY (short‑term US Treasuries). SPY is the non‑levered S&P 500 tracker it measures. Each day, 15 mini‑rules run. For each: if SPY’s recent daily swings (14–42 days) are below 1%, 1.5% or 2%, compare momentum using RSI (a score of recent up vs down days; higher = stronger). If SPY’s RSI is lower than SHY’s, buy UPRO; otherwise hold SHY. If volatility isn’t low, hold SHY. All 15 sleeves are equal‑weighted, so you can end up partly in each.
CheckmarkValue prop
Out-of-sample: ~49% vs ~22% annualized, Sharpe ~1.60 vs ~1.38, Calmar ~1.33. 15 sleeves lever UPRO only in calm regimes, otherwise SHY—higher upside with controlled risk (drawdowns possible).

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.
