About

Equal-weight, rules-based bet on cybersecurity, clean energy and hydrogen. Buy in each sleeve only when it’s trending up and not too shaky; otherwise park that sleeve in T‑Bills (BIL). Reviewed and rebalanced monthly.
NutHow it works
Split the portfolio into 3 equal parts: cybersecurity, clean energy, and hydrogen/clean tech. For each part, choose from ETFs (Cyber: BUG/CIBR/HACK; Clean: ICLN/TAN; Hydrogen: PBW/HJEN) only if price is above its ~50‑day average (uptrend) and its worst drop in ~30 days is under 15%. Otherwise hold BIL (short‑term T‑Bills). Rebalance monthly.
CheckmarkValue prop
Three-sleeve, trend-filtered bets on cybersecurity, clean energy & hydrogen. Cash fallback to BIL reduces drawdown; monthly rebalancing targets leaders, aiming for better risk-adjusted returns vs. the S&P 500 in out-of-sample tests.

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.
