Weekly Regime Outlook

Model-conditional probabilities that each asset is in a given market regime 21 trading days from now — from a preregistered, out-of-sample-validated covariate model, refreshed weekly. Data through 2026-08-21, generated 2026-08-24.

These are probabilities of membership in operationally defined regime classes (trailing 21-day volatility/drift quantile labels) — not a forecast of returns or market direction, and not investment advice. The number in parentheses is the unconditional baseline: what you would assign knowing nothing about current conditions. Where the model and the baseline differ is exactly what current observable state adds.

Cross-category market map

One compressed view across 18 category proxies — US large-cap, the nine SPDR sectors, international equity, bonds & credit, commodities, Bitcoin — on the same operational regime classes and the same 21-day horizon. No direction is forecast: each row carries regime-membership and stress probabilities only, and each (asset, horizon) cell ships exactly the model tier that passed a preregistered out-of-sample rule (covariate / persistence / unconditional).

• = stress probability materially above the row’s own unconditional baseline (≥ max(15%, 1.5×)). US sector rows largely re-express one common equity factor — the map is fewer independent signals than rows. Full per-category detail (probability vectors, baselines, conditional forward-return quantiles as historical description, equity-factor commonality, per-cell DM p-values) is in /outlook.json under market_map, daily-refreshed via the market_regime_map MCP tool. Descriptive, not advisory; no ranking is implied.

How to read this

The four classes are operational labels computed from each asset’s own history — BULL (positive trailing drift, calm volatility), SIDEWAYS (the residual class — no strong drift/vol signature), BEAR (negative trailing drift, elevated volatility), CRISIS (volatility above its expanding 90th percentile). Thresholds are expanding-window quantiles, so a label never uses information from after its own date.

Validation: Out-of-sample 2013-2025, expanding-window yearly refits: covariate logit beat the persistence-Markov baseline (DM p<0.05) on SPY/QQQ/TLT at h=5 and h=21; GLD h=21 direction-only. Persistence baseline beat the unconditional distribution in 8/8 cells. Annual Fourier seasonality terms were tested and FALSIFIED out-of-sample (0/8 cells improved; significantly worse on GLD and SPY h=21) — excluded from this model.

Model tier: covariate_logit_v1, refit on the full available history (6,176 training pairs) — the preregistered expanding-window protocol, applied at load time. Probabilities are shrunk toward the unconditional distribution; stress-class estimates carry the widest uncertainty and tend to be slightly conservative.

Data & archive

This snapshot as JSON: /outlook.json — dated snapshots accumulate at /outlook/archive/ (e.g. 2026-W35.json), so a citation of “the 2026-W35 outlook” stays checkable after the page moves on. Every payload carries data_through and per-asset data_staleness_days — verify freshness yourself.

Methodological limitations

  • Probabilities are model-conditional statements about membership in operationally defined regime classes (trailing 21-day volatility/drift quantile labels) — not predictions of returns or market direction, and not a claim about future market behavior.
  • Validated out-of-sample under a preregistered protocol (expanding-window, 2013-2025): the covariate model beat the persistence baseline at p<0.05 on SPY/QQQ/TLT; on GLD at h=21 the improvement was directional but not significant. Only horizons of 5 and 21 trading days and the four listed assets are validated — other inputs are rejected rather than extrapolated.
  • The model mildly underpredicts the two stress classes (e.g. realized CRISIS share 5.6% vs predicted 4.4%, SPY h=21 test window); treat stress probabilities as slightly conservative.
  • BEAR/CRISIS days are rare (~10% of history each); conditional estimates for stress regimes carry the widest uncertainty. Probabilities are shrunk toward the unconditional distribution.
  • Annual seasonality terms were tested and falsified out-of-sample; calendar patterns are deliberately not part of this model.
  • The underlying price history is refreshed daily with end-of-day bars (no intraday feed): the outlook is computed at the end of the stored series (see data_through / data_staleness_days), which typically lags the present by one trading day.
  • Descriptive, not advisory. No suitability, timing, or ranking claim is made or implied.
