A one‑holding switcher: buys UVXY when stocks look overheated, buys leveraged stock funds on deep dips, or—if no extremes—chooses risk‑on (S&P/short‑VIX) when SPY beats KMLM, or risk‑off (managed‑futures/hedges) when KMLM leads.

It holds one fund at a time and follows simple rules: 1) If several stock funds look “too hot” on a 10‑day score (RSI = a 0–100 speedometer; >~80), it buys UVXY, which jumps when fear spikes. 2) Else if volatility is already hot, it holds a milder vol fund (VIXM) or an S&P 500 bull fund. 3) Else if big leveraged tech/semis/S&P funds look “washed out” (RSI<30), it buys them for a bounce. 4) Else it compares SPY vs KMLM (a diversified trend‑following futures fund). If SPY is stronger, it picks an S&P bull or a “short VIX” fund (SVIX). If KMLM is stronger, it rotates into calmer hedges (Treasuries, volatility, long/short stocks, U.S. dollar), favoring the least jumpy.

Out-of-sample edge: Sharpe ~1.79 vs SPY ~1.14; annualized return ~186% vs ~20%; Calmar ~7.31. A disciplined, one-holding switcher exploiting volatility spikes, oversold bounces, and macro hedges. Drawdowns higher (25.4% vs 18.8%), but risk-adjusted gains win.
