A rules‑based “inflation alarm” portfolio: if long‑term rates are surging, it shifts into commodities, gold, energy, healthcare, and short long‑bonds (plus a big tilt to the most active asset). Otherwise, it stays in QQQ (big US tech).

Each day it asks: are long‑term Treasury prices plunging? It checks if TBT (a fund that rises when long bonds fall) is up ≥10% over ~3 months. If yes: 50% in DBC (commodities), GLD (gold), TBF (short long Treasuries), XLE (energy), XLV (healthcare), and 50% in whichever of those (or QQQ: big US tech) moved most in 2 weeks. If no: 100% QQQ. Rebalances daily.

Out-of-sample edge: ~20.5% annualized return with strong risk-adjusted metrics, enabled by inflation hedges (commodities, gold, energy, healthcare, short Treasuries) and a tech tilt in calm markets. Slightly higher drawdowns vs. the S&P, but bigger upside.
