A daily switch that uses short-term momentum in credit markets to size risk: 3x or 2x Nasdaq-100 when credit leads, and 50/50 T-Bills plus Gold when it doesn’t.

Each day it reads short-term momentum (RSI = a 0–100 “heat” score of recent moves, using 10 days). If preferred stocks (PFFD, PFFA) and corporate bonds (IGIB) look stronger than big US stocks (VV), it buys aggressive Nasdaq-100 (TQQQ). If only partly strong, it uses a milder version (QLD). If weak, it parks in 50% T-Bills (BIL) and 50% Gold (GLD).

Out-of-sample edge: Sharpe ~3.74 vs SPY 2.86; annualized return ~102% vs ~35%; Calmar ~14.3. It tactically shifts into defense to limit losses and still targets Nasdaq-100 upside. Higher upside with disciplined risk.
