About

A simple cash‑like approach: keep 100% in BIL (1–3 month U.S. Treasury bills). Seeks steady, low‑volatility income near prevailing T‑bill rates; daily rebalancing keeps the allocation fixed.
NutHow it works
The portfolio always holds 100% in BIL, an ETF that owns very short‑term U.S. Treasury bills (1–3 months). It rebalances daily to keep everything in BIL. No signals or market timing—returns mainly come from current T‑bill yields, with very small price swings.
CheckmarkValue prop
Ultra-short, cash-like: 100% in BIL with daily rebalancing. Out-of-sample stats show very low volatility, tiny drawdowns, and solid risk-adjusted returns near 4% annual yield—much less risk and better preservation than 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.
