80% core in QQQ with cash/Stable Money, 20% decision to use TQQQ only if QQQ’s long-run health is decent and market risk signals permit; otherwise shift 20% to SHY/VCSH. No regular rebalancing; use an 8% drift tolerance. Leveraged exposure used sparingly and only under predefined risk checks.

- Allocation setup: 80% of the portfolio is aimed at QQQ (Nasdaq-100 tech-heavy exposure) and a stable-money sleeve; 20% is reserved for a conditional decision. The 80/20 split is established with a short smoothing window (about 5 days) to avoid sudden swings. - Leveraged option: If market signals permit, the strategy allocates 20% of capital to TQQQ (3x levered QQQ) when the long-run health of QQQ looks solid and market risk is not overly stressed. This is not a constant lever; it is conditional and used only under favorable signals. - Signal 1 (long-term health): Check QQQ’s cumulative return over the last 1000 days. If it is better than -5%, the levered sleeve can be considered for the 20% allocation to TQQQ. If this condition is not met, the 20% sleeve shifts into bonds (SHY and VCSH). - Signal 2 (risk gate): A risk gate uses SPY drawdown signals. If the short-term (20-day) max drawdown of SPY is less severe than its longer-term (180-day) max drawdown, the levered/bond decision process proceeds; otherwise, the system leans toward the bond hedge and away from leveraging. - Bond hedge fallback: If the levered pathway is not triggered, the 20% sleeve is allocated to short-term bonds (SHY and VCSH) for risk reduction. - Rebalancing rule: The model does not rebalance on a fixed schedule. Instead, it uses a corridor width of about 0.08 (8%) to allow drift; only when weights drift beyond that corridor would a rebalancing action be triggered. Rebalancing corridor width = 0.08 means a small tolerance band around target weights to avoid frequent trading. - Assets used: QQQ (core), TQQQ (levered Nasdaq-100), SPY (risk benchmark), SHY (short-term Treasuries), VCSH (short-term corporate bonds). - Time horizon and risk: This is a tactical, not buy-and-hold strategy. It is designed for relatively short periods (levered exposure is inherently riskier) and may underperform in flat or down markets, especially when leverage is in use. - Practical note: The strategy is inspired by an article describing a leverage-focused approach that emphasizes risk controls and a cautious tilt toward leveraged Nasdaq exposure. It should be used with awareness of leverage risk and potential for sharp drawdowns during market stress.

Out-of-sample edge: 30.5% annualized return with solid risk control (Calmar ~0.96, Sharpe ~1.08). 80/20 core QQQ with conditional 3x leverage and bond hedge; low turnover. Higher upside versus the S&P 500 with built-in risk checks.
