About

A rules-based switch between leveraged Nasdaq exposure (QLD) and cash-like T‑bills (BIL): invest when the trend is up, during short rallies, or on deep dips; step aside when markets are overheated or in downtrends.
NutHow it works
Daily check: If QQQ or SPY is extremely hot (RSI > 80), move to BIL, a cash‑like 1–3 month T‑bill fund. Else if SPY (the S&P 500 fund) is above its 200‑day average, hold QLD, a 2x daily Nasdaq‑100 fund. If SPY is below, still hold QLD during short rallies (above 25‑day avg) or deep dips (QQQ RSI < 30). Otherwise stay in BIL. RSI is a simple hot/cold gauge.
CheckmarkValue prop
Out-of-sample edge: ~66.7% annual return vs SPY ~26.7%, with strong risk-adjusted upside (Calmar ~4.25). Nasdaq leverage in up markets; cash in overheated/weak regimes for disciplined risk management.

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.
