# Analyzing Multi Asset Strategies

## When To Use

- Evaluating a multi-asset fund's strategic and tactical allocation framework
- Assessing regime-detection models and their impact on portfolio positioning
- Comparing dynamic allocation approaches (risk parity, momentum overlay, macro-factor timing)
- Reviewing rebalancing triggers, drift tolerances, and transition cost management
- Analyzing how a strategy performed across distinct market regimes (expansion, contraction, crisis, recovery)

## Inputs To Gather

- **Strategy documentation**: Investment policy statement, allocation guidelines, regime-classification methodology, and any TAA (tactical asset allocation) overlay rules
- **Portfolio holdings**: Current and historical asset-class weights (equities, fixed income, commodities, alternatives, cash), including sub-asset-class granularity where available
- **Return and risk data**: Time series of portfolio and benchmark returns, volatility, drawdowns, and risk-factor exposures (minimum 5 years; 10+ preferred for regime analysis)
- **Regime definitions**: The model's regime-identification method (e.g., HMM, threshold-based macro indicators, yield-curve signals) and historical regime labels with date ranges
- **Benchmark and peer group**: Composite benchmark composition and peer-fund universe for relative comparison
- **Cost and implementation data**: Transaction costs, management fees, bid-ask spreads, and any constraints (liquidity buckets, leverage limits, derivative usage rules)

## Workflow

1. **Map the allocation framework**
   - Document the strategic asset allocation (SAA) targets and permissible ranges per asset class
   - Identify the TAA overlay: what signals drive deviations from SAA, how large deviations can be, and how frequently the model updates
   - Classify the approach (discretionary macro, systematic quantitative, hybrid) and note governance structure for allocation decisions

2. **Evaluate the regime model**
   - Review regime-identification methodology: input variables, lookback windows, transition probabilities or threshold triggers
   - Test regime labels against known market events (e.g., 2008 GFC, 2020 COVID, 2022 rate-hiking cycle) — confirm the model identifies regime shifts with acceptable lag
   - Assess false-positive rate: how often the model signals a regime change that reverses within one rebalancing period
   - [VERIFY] Whether the regime model uses in-sample or out-of-sample calibration and the date of last recalibration

3. **Analyze allocation dynamics**
   - Chart asset-class weights over time against regime labels to visualize responsiveness
   - Calculate average allocation shift magnitude per regime transition and compare to permissible TAA bands
   - Measure turnover generated by regime-driven rebalancing and estimate implementation drag (transaction costs + market impact)
   - Identify periods where allocation changes lagged regime shifts by more than one rebalancing cycle

4. **Decompose performance by regime**
   - Segment total returns into regime buckets; compute annualized return, volatility, Sharpe ratio, and max drawdown per regime
   - Run return attribution: how much of excess return vs. benchmark came from SAA, TAA timing, and security/instrument selection
   - Compare regime-conditional performance to a static SAA portfolio to quantify the value-add of dynamic allocation
   - Flag any regime where the strategy underperformed a static mix by more than 100 bps annualized

5. **Stress-test and scenario analysis**
   - Apply historical stress scenarios (rate shocks, credit spread widening, equity drawdowns >20%) and measure portfolio response
   - Simulate delayed regime detection (add 1–3 month lag) to gauge sensitivity to signal timing
   - Test correlation breakdown scenarios where diversification assumptions fail (e.g., equity-bond correlation turning positive)

6. **Assess risk controls and constraints**
   - Verify that portfolio stayed within stated allocation bands, leverage limits, and liquidity requirements throughout the analysis period
   - Review drawdown management rules: are there hard stop-loss triggers, volatility-targeting overlays, or tail-risk hedges?
   - [VERIFY] Compliance with any regulatory constraints on asset-class eligibility or concentration limits applicable to the fund type

## Output

Produce an **Analysis Report** containing:

- **Executive summary**: One-paragraph verdict on whether the multi-asset strategy's regime-based allocation adds measurable value over a static benchmark
- **Allocation framework overview**: SAA targets, TAA bands, regime model type, and governance process
- **Regime model assessment**: Accuracy of regime identification, lag characteristics, false-signal rate, and recalibration frequency
- **Performance attribution table**: Returns, risk metrics, and attribution (SAA vs. TAA vs. selection) segmented by regime
- **Dynamic allocation scorecard**: Turnover efficiency, implementation cost drag, and net value-add of tactical shifts
- **Risk and stress-test results**: Drawdown analysis, scenario outcomes, and correlation-breakdown sensitivity
- **Findings and recommendations**: Specific, actionable observations (e.g., "TAA bands could widen in recovery regimes where the model shows consistent positive alpha" or "Regime detection lag during the 2020 crisis cost approximately 180 bps")

## Quality Checks

- Confirm return data is net-of-fees or clearly labeled gross; do not mix the two in comparisons
- Validate that regime labels align with recognized market chronology — flag any proprietary regime classification that contradicts consensus dating
- Ensure attribution components sum to total excess return within rounding tolerance
- Verify that Sharpe ratios and drawdown figures use consistent annualization and compounding conventions
- Check that turnover and cost estimates reflect actual implementation (not theoretical frictionless rebalancing)
- Mark any data gaps, survivorship bias concerns, or backfill issues with [VERIFY]
- Do not present backtested regime-model results as equivalent to live performance without explicit disclaimer
