About
A monthly, equal-sleeve trend strategy in SPY (S&P 500), QQQ (big tech), and IWM (small caps). Each sleeve holds its ETF when the last ~30 trading days are net positive; otherwise it shifts to cash-like T‑Bills (BIL) or Treasuries (IEF) for protection.
Each month, your money is split into 3 equal parts (sleeves).
- Sleeve 1: If the S&P 500 (SPY) had a net-positive last ~30 trading days, hold SPY; otherwise hold T‑Bills (BIL).
- Sleeve 2: If big tech (QQQ) is up over ~30 days, hold QQQ; otherwise hold 7–10 yr US Treasuries (IEF).
- Sleeve 3: If small caps (IWM) are up, hold IWM; otherwise hold BIL.
Goal: ride uptrends, hide in safer assets when trends turn down.
Risk-managed trend overlay across 3 US sleeves: participate in uptrends, protect in pullbacks. Out-of-sample Sharpe 1.60 vs SPY 1.37; max drawdown 6.8% vs 13.7%; beta 0.41; Calmar 3.04; ~20.7% OOS return (SPY ~24.5%).
