A daily risk-on/risk-off switch: ride leveraged tech (TQQQ) in calm uptrends, flip to long Treasuries (TMF) or short‑term Treasuries (SHY) in stress, park in T‑bills (BIL) when bonds lag, and briefly hedge with UVXY when tech looks overheated.

Checked daily; the portfolio holds one fund at a time. - If tech (TQQQ) is extremely hot, briefly hedge with UVXY. - Else if stocks just fell hard, hide in short‑term Treasuries (SHY). - Else if core bonds (BND) beat cash‑like bonds (GSY): buy TQQQ if stock damage is mild; otherwise buy long Treasuries (TMF). - If bonds aren’t strong, sit in T‑bills (BIL).

Dynamic, rules-based rotation between leveraged tech and Treasuries with a UVXY hedge. It adds diversification and a clear risk-control framework to complement the S&P 500, offering a measured out-of-sample risk-adjusted profile (Sharpe ~0.33).
