About

Daily switches between SPY and cash‑like T‑bills: buy SPY when it’s briefly weak or clearly strong; hold BIL when prices are in a middling zone between short‑term and long‑term trend signals.
NutHow it works
Each day it compares SPY (a fund that tracks the 500 biggest U.S. stocks) to two simple averages of past closing prices: 6 trading days and ~1 year (259 days). If price is below the 6‑day average or above the 1‑year average, it buys SPY. Otherwise it holds BIL, a fund of very short‑term U.S. Treasury bills. Rebalanced daily.
CheckmarkValue prop
Smart balance: participate in SPY upswings, switch to cash in middling markets. Out-of-sample: beta ~0.91, drawdown ~18.8%, return ~15.9%, Sharpe ~0.91. SPY-like upside with a smoother, lower-risk ride.

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.
