How to Properly Analyze Multiple Trading Strategies
Master the statistical methods for comparing trading strategies and building robust portfolios with scientific precision. Learn from academic research on Modern Portfolio Theory and risk-adjusted performance metrics.
Why Multi-Strategy Analysis
Most traders make the same costly mistake: they analyze strategies one at a time, missing the bigger picture. But professional fund managers think differently—they analyze multiple strategies together to build portfolios that are more profitable and less risky than any individual strategy.
The science behind this approach comes from Nobel Prize winner Harry Markowitz's Modern Portfolio Theory and decades of academic research. Studies show that properly constructed multi-strategy portfolios can improve risk-adjusted returns by 30-50% compared to single-strategy approaches.
Your Multi-Strategy Analysis Action Plan
Professional portfolio construction isn't just about picking good strategies—it's about combining them scientifically to create something better than the sum of its parts. Here's your step-by-step implementation guide:
Collect and Compare
Gather all your strategy backtests and compare them using risk-adjusted metrics, not just returns.
Stress Test Individual Strategies
Run Monte Carlo simulations on each strategy via the Strategy Analysis modal—you may get some surprises that change which strategies make the cut.
Build Your Portfolio
Select your validated strategies in the Portfolio tool and choose a weighting method (Equal, Account Size, or Risk-Adjusted) to see combined metrics.
Validate Out-of-Sample
Test your portfolio on data not used in construction to verify real-world viability before committing capital.
Monitor and Rebalance
Regularly review performance and adjust weights as market conditions change.
Statistical Performance Comparison
The Foundation: Before building portfolios, you need to properly compare individual strategies. This isn't just about looking at returns—it's about understanding which differences are statistically meaningful.
• Net Profit: Total gains/losses from strategy
• Profit Factor: Gross profit divided by gross loss
• Win Rate: Percentage of profitable trades
• Total Trades: Sample size for statistical validity
• Max Drawdown: Worst peak-to-trough loss
• Net Profit / Drawdown: Recovery potential ratio
• Risk of Ruin: Probability of hitting ruin threshold
• Recovery Duration: Trades to return to equity peaks
Never compare strategies based on total returns alone. A strategy with 20% returns and 40% drawdown is far riskier than one with 15% returns and 10% drawdown. Always use risk-adjusted metrics.
Portfolio Construction & Risk Reduction
Running a single strategy exposes you to concentrated risk. When that strategy hits a losing streak, your entire account suffers. Combining multiple strategies into a portfolio spreads risk and creates more consistent returns—even when individual strategies underperform.
• Account Size: Weight by each strategy's capital
• Equal Weight: Divide allocation evenly
• Risk-Adjusted: Weight inversely to drawdown
• Lower Drawdowns: Portfolio vs worst individual strategy
• Smoother Equity: Losses offset by other strategies
• More Opportunities: Combined trade count increases
• Reduced Variance: Less account volatility
• Multiple Symbols: Diversify across markets
• Multiple Timeframes: Capture different moves
• Capital Efficiency: Shared margin requirements
• Trading Consistency: Always active in markets
Optimal Portfolio Weight Allocation
Once you've selected your strategies, how much capital should you allocate to each? Equal weighting is simple but rarely optimal. Different weighting methods create different risk-return profiles for your portfolio.
• Method: Weight by each strategy's initial capital
• Formula: Strategy capital ÷ total capital
• Best for: Matching portfolio to actual account allocations
• Method: Divide allocation evenly across strategies
• Formula: 1 ÷ number of strategies
• Best for: Simple, unbiased allocation without assumptions
• Method: Weight inversely to max drawdown
• Logic: Lower drawdown = higher allocation
• Best for: Prioritizing capital preservation and risk control
What Happens After Analysis
BacktestBase helps you compare strategies, build portfolios, and stress test with Monte Carlo simulations. But the final validation happens in live markets—and that part is up to you. Here's what to do next and what to watch for.
• Paper trade your portfolio in real-time conditions
• Track execution vs backtest assumptions (slippage, fills)
• Compare results to stress test median (50th percentile)
• Duration: At least 30-50 trades before going live
• Start small: Use reduced position sizes initially
• Scale gradually: Increase size as confidence builds
• Monitor drawdowns: Stay within stress test projections
• Re-test periodically: Market conditions change over time
• Below 5th percentile: Stop trading and re-evaluate
• Check execution: Are costs higher than assumed?
• Regime change: Has market behavior shifted?
• Possible overfit: Strategy may have been curve-fitted
When to Rebalance Your Portfolio
Your initial BacktestBase analysis gives you optimal weights—but markets change. Over time, some strategies will outperform (growing beyond their target allocation) while others underperform. Knowing when to rebalance is part of ongoing portfolio management.
• Schedule: Monthly, quarterly, or annually
• Action: Reset weights to original targets
• Re-analyze: Upload fresh backtests to BacktestBase
• Best for: Systematic, emotion-free discipline
• Trigger: When weights drift 5-10% from target
• Example: 30% target → rebalance at 35% or 25%
• Benefit: Responds to actual performance changes
• Best for: Active risk management
• Watch: Strategies falling below 5th percentile
• Signal: Correlation changes between strategies
• Action: Re-run stress tests with updated data
• Best for: Catching regime changes early
