Tactical switch between 3x long or 3x short biotech using simple “heat” checks across stocks vs Treasuries, with an extra filter when the S&P 500 runs hot. Keeps a cash buffer and typically trades no more than every ~2 weeks.

What it does: flips between 3x long biotech (LABU) or 3x short biotech (LABD). Uses RSI, a short‑term “hot/cold” score of recent price moves. 1) Checks if the S&P 500 (SPY) looks very hot. If yes, it also checks long‑term Treasuries (TMF). 2) Compares momentum in small‑caps (IWM) vs Treasuries (IEF). If stocks are stronger it usually goes long; if bonds are stronger it usually goes short. When SPY is very hot, the TMF check can flip this test. About 70–80% is invested (rest in cash). Trades switch no more than ~every 15 days. Uses 3x ETFs (very high risk). Tickers: LABU/LABD=3x biotech up/down; IWM=small‑caps; IEF=7–10y Treasuries; TMF=3x 20+y Treasuries; SPY=S&P 500.

Out-of-sample edge: ~39.7% annualized returns vs SPY ~19%, with positive alpha. Allocates ~72% to 3x biotech bets and ~28% cash. Higher upside from timing signals, but expect wider drawdowns than SPY in stressed markets.
