Dip when QQQ falls: heavy tilt to 3x Nasdaq ETF (TQQQ) with a bond hedge. Not in a dip: lean toward bonds (BSV) plus a Nasdaq-100 ETF (QQQM) for safer exposure.

- The strategy watches recent QQQ performance. If QQQ has dipped (measured by a four-period cumulative return being below a threshold, e.g., down about 4%), it shifts into a Nasdaq-focused levered bet by buying TQQQ heavily (and a smaller bond hedge). - If QQQ is not in a dip (or is emerging from a dip), the strategy adopts a defensive mix: around 60% in BSV (short-term U.S. government bonds) and 40% in QQQM (a Nasdaq-100 ETF without leverage). - The mix aims to exploit rebounds after dips (with amplified exposure when risk is perceived as favorable) while limiting drawdowns through bonds when markets aren’t in a dip. Leverage means faster gains and losses; bonds help dampen swings. Fees and daily-reset effects of leveraged ETFs apply, so true performance depends on the path of markets, not just end points.

Out-of-sample: Sharpe ~2.08 vs SPY 1.73; Calmar ~6.13; max drawdown ~3.17% vs SPY ~5.07%; annualized return ~19.43% vs SPY 20.20%. Strong risk-adjusted upside with a bond hedge and dip-driven leverage that limits drawdowns.
