Best Momentum Strategies for Strong Stocks: All-Weather & Bear Market Resilience
Comprehensive analysis of momentum-based strategies for fundamentally strong stocks, identifying 'Quality Rating Momentum' as the all-weather winner and 'Quality Mean Reversion' as the top performer during bear markets, based on 32 backtests across diverse market regimes (2020-2024).
User: Create the best momentum-based strategy for fundamentally strong stocks
Aurora: Great goal! Combining momentum with fundamental quality is a time-tested approach that aims to capture the best of both worlds: riding winners while filtering out low-quality stocks that might be rising on speculation alone. To design the most effective experiment for you, I need to clarify a few things: 1. **What is your primary objective?** Are you looking to maximize absolute total return, achieve the highest risk-adjusted return (Sortino Ratio), or balance both while minimizing drawdowns? 2. **What's your preferred universe?** Should we focus on: - Large caps only (S&P 500)? - A broader universe (all US stocks with fundamental filters)? - A specific sector (e.g., technology)? 3. **How do you define "fundamentally strong"?** Some options include: - Positive net income and free cash flow - Low debt ratios (Debt/Assets < 0.5) - High StockReport rating (our 0-5 quality score) - Strong revenue/earnings growth (positive CAGR) - A combination of these? Once I understand your preferences, I can propose competing hypotheses testing different momentum signals (RSI, price rate of change, Bollinger Bands, moving average crossovers) combined with various quality filters to find what truly…
User: maximize risk-adjusted returns and great gains during a bear market. try different things and see what works
Aurora: This is an excellent and ambitious goal. You want a momentum strategy for fundamentally strong stocks that maximizes risk-adjusted returns AND performs well during bear markets—a challenging but achievable combination. I will design a comprehensive experiment to discover what truly works. ### The Core Question Can we construct a momentum-based strategy for fundamentally strong stocks that delivers superior risk-adjusted returns (Sortino Ratio) while also providing downside protection during bear markets? ### Competing Hypotheses 1. **Hypothesis A (Pure Quality Momentum):** The best approach is to filter for fundamentally strong stocks (positive earnings, low debt, high quality scores) and then select the top performers by momentum. Quality filters alone provide sufficient downside protection. 2. **Hypothesis B (Defensive Momentum Rotation):** Superior bear market performance comes from dynamically rotating between aggressive momentum stocks during bull markets and defensive, high-quality dividend payers during bear markets (using a trend filter like SPY > 200 SMA). 3. **Hypothesis C (Mean Reversion on Quality):** During bear markets, buying oversold (low RSI) fundamentally strong…
User: Create 8 portfolios to test momentum and fundamental quality: 1. 'Benchmark - SPY': Buy and hold SPY. 2. 'Hypothesis A - Quality Momentum': DynamicRebalance (ALL_US_STOCKS) monthly. Pipeline: Filter IsIndexMember(SP500), Filter TrailingSum(Fundamental(netIncome), 4) > 0, Filter Divide(Plus(Fundamental(longTermDebt), Fundamental(shortTermDebt)), Fundamental(totalAssets)) < 0.5, SelectTop 15 by PriceRateOfChange(30 days). Weight: Equal. 3. 'Hypothesis A - Quality Rating': DynamicRebalance (ALL_US_STOCKS) monthly. Pipeline: Filter IsIndexMember(SP500), Filter StockReport() > 3, SelectTop 15 by PriceRateOfChange(30 days). Weight: Equal. 4. 'Hypothesis B - Regime Adaptive': Two strategies. Strategy 1 (Bull): If Price(SPY) > SMA(SPY, 200), DynamicRebalance (ALL_US_STOCKS) to top 15 SP500 momentum stocks, maxAllocationPercent: 100. Strategy 2 (Bear): If Price(SPY) <= SMA(SPY, 200), DynamicRebalance (ALL_US_STOCKS) to top 15 SP500 dividend payers with StockReport > 3, maxAllocationPercent: 60. 5. 'Hypothesis C - Quality Mean Reversion': DynamicRebalance (ALL_US_STOCKS) monthly. Pipeline: Filter IsIndexMember(SP500), Filter TrailingSum(Fundamental(netIncome), 4) > 0, Filter StockReport() >…

User: Analyze the backtest results for the 32 backtests executed across 8 portfolios and 4 time periods (2020, 2022, 2023, and 2024). Please provide a comprehensive summary and comparison of performance metrics for each portfolio: 'Benchmark - SPY', 'Hypothesis A - Quality Momentum', 'Hypothesis A - Quality Rating', 'Hypothesis B - Regime Adaptive', 'Hypothesis C - Quality Mean Reversion', 'Hypothesis D - Vol-Weighted Momentum', 'Hypothesis E - Multi-Signal', and 'Hypothesis E - Golden Cross'. Focus on Total Return, Maximum Drawdown, Sharpe Ratio, and Sortino Ratio, with particular emphasis on identifying which strategies delivered the best risk-adjusted returns and capital protection during the 2022 bear market.
