Switches playbooks: in rough markets it buys sharp dips with 3x stock ETFs or sits in a safety basket; in calm bull markets it runs a higher‑growth mix of UPRO/TQQQ + TMF, otherwise returns to the same safety basket.

Step 1: Is the S&P 500’s worst drop in the last year over 10%? If yes, it’s “bear.” If no, it’s “bull.” Bear: Split in two. For Nasdaq and S&P slices, buy 3x ETFs after a ~5% weekly drop (TQQQ=Nasdaq‑100, UPRO=S&P 500), unless today already jumped >5%; otherwise use a safety basket (UUP=US dollar, GLD=gold, XLP=consumer‑staples). Bull: If calm/trending, go risk‑on: ~55% UPRO/TQQQ (balanced by volatility) + ~45% TMF (3x long Treasuries). If not calm, use the safety basket. Weights refresh about monthly.

Dynamic regime-switching strategy that shifts between bear-dip buys and bull-growth exposure to diversify a core SPY holding. OOS: ~12.6% vs SPY ~22.8%, with higher drawdowns (~34.7% vs ~18.8%). A complementary, adaptive risk path.
