A simple switch: if short‑term bonds look steadier than the inverse‑Nasdaq fear gauge, it goes risk‑on with TSLA and MicroStrategy; otherwise it plays defense with UnitedHealth and Costco. Uses a 20‑day recent‑strength score and minimal rebalancing.

It checks a 20‑day “recent‑strength” score (RSI: 0–100 measuring recent ups vs downs) for two gauges: BSV = short‑term U.S. bonds; SQQQ = an ETF that jumps when big tech falls. If BSV’s score > SQQQ’s: buy TSLA + MicroStrategy (sized by company size). Else: own UnitedHealth + Costco 50/50. Trades mainly when the signal flips or weights drift ~10%.

Rules-based regime switch: risk-on TSLA/MSTR, risk-off UNH/COST. Out-of-sample tests show higher risk-adjusted returns and lower drawdowns vs the S&P 500, with low turnover and built-in downside protection.
