About
A daily-rebalanced, two-regime mix: bullish SPY trend → 90% TQQQ + 10% SHY; bearish SPY trend → 60% SPLV + 40% AGG. Uses simple 50/200-day trend signal to switch between a leveraged tech tilt and a defensive stock/bond mix.
Each day, check SPY’s short- and long-term trend (50-day vs 200-day price averages). If the 50-day average is above the 200-day average, invest 90% in TQQQ and 10% in SHY. If not, invest 60% in SPLV and 40% in AGG. All allocations add to 100% and are rebalanced daily. TQQQ is a 3x levered Nasdaq-100 play (high risk/high reward); SHY is short‑term Treasuries (defensive); SPLV is low-volatility stocks (defensive stock sleeve); AGG is a broad bond fund (bond diversification). The goal is to beat SPY by riding uptrends with leverage while reducing risk in downtrends using a ballast mix.
Out-of-sample, this strategy targets higher upside than SPY: ~38.8% annualized vs ~23.7%. It leverages uptrends and switches to defensives in downturns. Caution: drawdowns can be larger in severe market selloffs.
