About

Holds SPY in uptrends. When the market weakens, it buys tech (XLK) only after a sharp dip signaled by QQQ’s 10‑day RSI < 30; otherwise it parks in consumer‑staples (XLP). Checked daily; backtested since 1999.
NutHow it works
Each day: 1) If SPY (S&P 500 fund) is above its 200‑day average, hold SPY. 2) If it’s below, check QQQ (Nasdaq‑100) RSI over 10 days. RSI is a 0–100 gauge of how fast price fell/rose; under 30 = a sharp drop. If QQQ’s RSI < 30, buy XLK (tech sector). Otherwise hold XLP (consumer‑staples) as a steadier, cash‑like spot. Starts 1999.
CheckmarkValue prop
Out-of-sample, this strategy beats the S&P 500 on a risk-adjusted basis: ~26.5% annualized return vs ~22.5%, ~11% max drawdown vs ~19%, and higher Sharpe/Calmar. Trend-following tech-dip rotation lowers risk while boosting upside.

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.
