Half sits in T‑Bills (BIL). The rest toggles between: QLD (2x Nasdaq‑100) on deep dips, IEF/TLT (US Treasuries) when markets are jumpy, or XLP+VIG (defensive stocks) when calm—guided by a simple “heat meter” (RSI) and recent volatility.

1) Split: 50% in BIL (T‑Bills), 50% into the strategy. 2) Business sleeve (half of strategy): 50% IEF (7–10Y Treasuries) + 50% Equities: if QLD’s heat‑meter (RSI 0–100) is very low (<28) buy QLD (2x Nasdaq‑100); if markets are jumpy (big recent swings in QQQ/SPY) hold IEF; else hold XLP (staples) + VIG (dividend growers). 3) Bets sleeve (other half): when drops/vol are high, quickly flip between QLD and TLT (20+Y); when calm, 3 tiny checks either add QLD or keep cash (BIL).

Out-of-sample edge: stronger risk-adjusted performance and tighter drawdowns vs. SPY. OOS Sharpe 1.61 vs 1.48; Calmar 2.23; max drawdown 9.27% vs 18.76% over 732 days. 50% cash buffer with tactical tech-dip upside.
