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 2026-07-14, generated 2026-07-15.
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.

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 (6,148 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.

This snapshot as JSON: /outlook.json — dated snapshots accumulate at /outlook/archive/ (e.g. 2026-W29.json), so a citation of “the 2026-W29 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.
