Sample portfolio review

Equal capital. Different risk.

Synthetic mechanics example
50% fictional equity sleeve / 50% fictional bond sleeve initially.

Generated prices · 3 February 2025 · no live market data

One-session volatility: 0.43%
Portfolio principal eigenspaces: 1.41

Historical moment window 2024-01-03–2025-02-03; effective sample 272.0. Daily simple-return units. Model-implied covariance at saved closing weights. Principal eigenspaces are statistical directions, not causal economic factors or independent bets.

Empirical investment benefit: unavailable. These are calculated fixture outputs, not economic evidence.

One portfolio, one useful question

Does 50/50 capital mean 50/50 risk?

In this generated example, the equity sleeve has the larger variance allocation. The bond sleeve has a negative loading on the fictional common return component; residual risk still matters.

What deserves review

Inspect the signed exposures, drifting closing weights and reconciled risk table. Compare conditional estimates only where the sample supports them.

What changed? No previous comparable run is available. No allocation change is prescribed.

Three deliberate steps

From holdings to a review you can explain.

Commit the portfolio

Enter holdings and capital weights. Confirm dates, coverage, sources and the return policy.

Build the evidence

Inspect variable meaning, units and available history before an explicit Build. Review measured exposures, risk and conditional structure with their uncertainty.

Review and export

Compare saved, compatible runs and frame specific questions. Export a brief and evidence bundle; session history is not durable storage.

Methods & supported scope

Evidence with its limits attached.

Current scope: long-only USD portfolios with complete, supported adjusted-return history and explicit cash treatment. Buy-and-hold or scheduled rebalancing; no automatic replacement of missing holdings.

Signed regression exposures, reconciled covariance risk and probability-weighted historical structure support review. Model settings, training cutoffs and data provenance stay visible.

A regime is a model estimate

Historical associations and principal components are not causal explanations or forward stress forecasts.
Membership probability is not forecast calibration. Readiness is not investment validation.
Validation can report no demonstrated improvement or insufficient evidence.
Current-holdings history is not your account performance record. Unsupported data makes the affected analysis unavailable.
