About

A daily, rules‑based switcher that rotates among leveraged S&P/Nasdaq funds, Berkshire, big blue‑chip stocks, oil, cash, and volatility ETFs, using short‑term trend, oversold bounces, and stock‑vs‑bond strength to decide.
NutHow it works
Rebalances daily. If SPY is short‑term weak (price < 5‑day avg), split across the 2 strongest S&P/Nasdaq funds (incl. 3x) plus Berkshire. Else: if Berkshire is weak (RSI<50) go to oil. If the 3x Nasdaq fund (TQQQ) just crashed (>12%/6d), buy VIX funds on big rebound days; otherwise try a bounce with big blue‑chips (OEF), or use Berkshire or oil/cash. In calmer times, own OEF when trend is up; if not, compare stock vs bond strength to choose OEF or oil/cash. MA=avg recent prices; RSI(0–100)=recent up vs down; drawdown=worst drop; cum return=% change. Key: SPY=S&P500; QQQ=Nasdaq‑100; BRK/B=Berkshire; SPXL/TQQQ=3x; OEF=top 100; USO/OILK=oil; VIXY/VIXM=vol; BIL=T‑Bills.
CheckmarkValue prop
Out-of-sample edge: Sharpe 1.82 vs 1.25; annualized return 69.66% vs 16.44%; Calmar 4.65. Drawdowns larger (~15% vs ~9%), but risk-adjusted gains are far stronger via adaptive, diversified rotations.

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.
