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:

1

Collect and Compare

Gather all your strategy backtests and compare them using risk-adjusted metrics, not just returns.

2

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.

3

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.

4

Validate Out-of-Sample

Test your portfolio on data not used in construction to verify real-world viability before committing capital.

5

Monitor and Rebalance

Regularly review performance and adjust weights as market conditions change.

03

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.

Performance Metrics

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

Risk & Recovery Metrics

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

Common Comparison Mistake

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.

04

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.

Portfolio Weighting Methods

Account Size: Weight by each strategy's capital
Equal Weight: Divide allocation evenly
Risk-Adjusted: Weight inversely to drawdown

Risk Reduction Benefits

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

Market Coverage & Efficiency

Multiple Symbols: Diversify across markets
Multiple Timeframes: Capture different moves
Capital Efficiency: Shared margin requirements
Trading Consistency: Always active in markets

05

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.

Account Size Weighting

Method: Weight by each strategy's initial capital
Formula: Strategy capital ÷ total capital
Best for: Matching portfolio to actual account allocations

Equal Weight

Method: Divide allocation evenly across strategies
Formula: 1 ÷ number of strategies
Best for: Simple, unbiased allocation without assumptions

Risk-Adjusted Weighting

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.

Forward Test First

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

If Results Match Expectations

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

If Results Diverge Significantly

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

07

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.

Time-Based Rebalancing

Schedule: Monthly, quarterly, or annually
Action: Reset weights to original targets
Re-analyze: Upload fresh backtests to BacktestBase
Best for: Systematic, emotion-free discipline

Threshold-Based Rebalancing

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

Performance-Based Review

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
