Rules-based swing trading around SOXL (3x semiconductor ETF). Uses a long-term trend filter and a short-term “speedometer” (RSI) to buy deep dips, fade extreme spikes, or rotate into SOXS, bonds, cash (SHV), and sometimes UVXY during stress.

Trades SOXL (3x bull semis). Uses trend + RSI(10) “speedometer” (0–100: low=oversold, high=hot). Uptrend: usually hold SOXL; buy deep dips (RSI<29). After huge spike (>8.5%) often flip to SOXS; after sharp drop (<‑2%) or very hot (RSI>80), go defensive. Downtrend: still buy extreme dips (RSI<30); if plunge (<‑6%), add UVXY. Defensive: if price sits between 20–90‑day avgs, pick the strongest of SOXS (3x bear), TLT/BND (bonds); else park in SHV (T‑Bills). Daily rebalancing; high risk.

Out-of-sample: ~33.4% annualized return vs ~18.5% for S&P, Sharpe ~1.41 vs ~0.93, max drawdown ~9.8% vs ~18.8%, Calmar ~3.40. Higher upside with disciplined trend/RSI rotation in semiconductors and hedges.
