About
Monthly, pick the 3 best performers from a global mix (US/international stocks, real estate, commodities, gold, Treasuries, T‑bills) based on ~7‑month returns, split equally. Rotates into risk-on or defensive assets as market leaders change.
Each month it looks back ~7 months (about 150 trading days), ranks 9 broad ETFs by total return, buys the top 3, and splits money equally (≈33% each).
ETFs: SPY (US large stocks), IWM (US small), EFA (developed intl), EEM (emerging), VNQ (US real estate), DBC (commodities), GLD (gold), TLT (long‑term US Treasuries), BIL (T‑bills/cash‑like).
It shifts between growth assets and safe havens as trends change.
Global momentum: monthly top-3 ETF picks across 9 assets aim to beat the S&P with higher risk-adjusted returns and smaller drawdowns. OOS: ~46%/yr vs ~29%; Sharpe ~3.22 vs ~1.41; max drawdown ~6.25% vs ~13.73%.
