A daily “risk switch” that uses bonds to judge stress. In calm times it rotates into 3x S&P/Nasdaq, buying the more oversold of the two. In stress it shifts to cash‑like bonds, USD, long/short defensives, commodities, or shorts; rate regime guides bond longs vs shorts.

First, ask: are bonds up over ~11 weeks (BND > 0%)? If yes (calmer), split into two slices. When volatility is low/moderate, each slice buys either 3x S&P (UPRO) or 3x Nasdaq (TQQQ) — whichever looks more “oversold” by RSI (a simple gauge of recent pressure; low = just fell). If vol spikes, that slice parks in SHY (cash‑like). If bonds are weak (stress), check rates. Rising rates: favor strong‑USD, commodities/market‑neutral and some inverse funds; if tech is extremely washed‑out, briefly buy a rebound (TQQQ) while shorting long bonds (TMV). Falling rates: hold long Treasuries (TMF), defensive stocks (XLP), anti‑beta (BTAL), and USD (USDU).

Out-of-sample, this strategy posts ~36.7% annualized return vs ~21% for the S&P, with a resilient risk-on/off framework and ~1.08 Sharpe. Dynamic hedges (bonds/USD/defensives) aim for big upside while dampening stress—though drawdowns can be larger.
