A rules‑based, medium‑aggressive mix: 50% growth that leans into tech when conditions are calm and turns defensive when rough; 25% flexible bond sleeve; 25% preservation via trend across Treasuries, gold, commodities, dollar, and cash.

It splits the portfolio into three sleeves: Growth 50%, Yield 25%, Preservation 25%. Growth: If the S&P 500 is calm, own broad stocks (SPY) or a turbo tech fund (QLD) when long Treasuries (TLT) are strong. If markets are jumpy, only buy QLD after a big dip; otherwise use a defensive mix (short Treasuries SHY, SPY, gold GLD, staples XLP, defensive long/short BTAL). Yield: Mix bond funds and lean into the steadier ones; buy TLT only when it’s calm, otherwise rotate among cash‑like T‑bills (SHV), the US dollar (UUP), gold (GLD), and high yield (HYG). Keep a core in 3–7y Treasuries (IEI). Preservation: Trend‑follow the strongest assets (stocks SPY, Treasuries TLT, gold GLD, commodities DBC, US dollar UUP, cash SHV) and keep extra gold. RSI = a quick “hot/cold” meter (low = washed out). Volatility = how bumpy prices have been. Momentum = recent winners.

Out-of-sample edge: Sharpe ~1.87 vs ~1.44; annualized return ~24.63% vs ~23.02%; max drawdown ~9.44% vs ~18.76%; Calmar ~2.61. A 3-sleeve rules-based strategy that grows in calm markets and hedges during turmoil, with lower risk than SPY.
