About

A daily switch that shorts the S&P 500 when it looks overheated or weak, parks in T‑bills when signals are mixed or bonds are stronger, and only buys tech (XLK) when big‑tech looks washed out (QQQ RSI is very low).
NutHow it works
Daily holds one fund: SH (inverse S&P 500), SHV (T‑bills), or XLK (tech). RSI = a 0–100 “heat” score; low = washed out, high = overheated. EMA/SMA = fast vs slow average; fast below slow = weak. Rules: If QQQ (big‑tech) RSI10<31, buy XLK. Else if SPY RSI10>85 or SPY 10‑day EMA<SMA, hold SH. If bonds (BND RSI20) beat SH RSI60, go to SHV. Otherwise SHV. Why: SH shorts the market, SHV is safe parking, XLK rides rare tech rebounds.
CheckmarkValue prop
Three-position, daily-rebalanced strategy: SH, SHV, or XLK when tech oversold. OOS drawdown ~8.46% vs SPY ~18.76%, Calmar ~0.98—better downside protection and solid risk-adjusted upside vs 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.
