About
Own SPY when the long-term trend is strong. If it softens, buy tech on deep dips or move to Treasuries. In bear markets, park mostly in T‑bills/Treasuries/Staples and use a small tactical sleeve to hedge or ride short tech/semiconductor rebounds.
1) If the S&P 500 (SPY) is in a clear uptrend (above key averages), own SPY. 2) If the trend weakens, only buy tech (XLK) on sharp dips in the Nasdaq (QQQ); otherwise hide in 3–7y Treasuries (IEI). 3) If SPY breaks down, hold mostly T‑bills (SHV), Treasuries (IEI) and Staples (XLP), plus a small tactical sleeve that can hedge (PSQ/QID) or play quick rebounds in QQQ/semis (SMH/QLD/USD).
Out-of-sample, this strategy outperforms SPY with smaller drawdowns: Sharpe 1.76 vs 1.45; 28.7% vs 23.2%; max drawdown 10.2% vs 18.8%; Calmar 2.82. It stays in SPY in uptrends and rotates to Treasuries/staples when risk rises, for smoother growth.
