About

A cash‑like strategy: always 100% in BIL (1–3 month U.S. Treasury bills). Seeks safety and current short‑term interest income with very low volatility; rebalanced daily. Not designed for growth or beating stocks.
NutHow it works
This puts 100% of your money in BIL, an ETF that holds very short‑term U.S. Treasury bills (1–3 months). These are loans to the U.S. government and are considered very safe. Rebalancing daily just keeps everything in BIL. You earn the going short‑term interest rate (minus fees). Expect very small price moves; it won’t capture stock market growth, and your income will drop if interest rates fall.
CheckmarkValue prop
Out-of-sample, this BIL cash-like strategy delivers superior risk-adjusted performance vs the S&P 500: minimal drawdowns, extremely high Sharpe/Calmar, and steady short-term yield—great for capital preservation with income.

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.
