32 of 79 historical Amber months. Same monthly sample for every horizon: Jan 2000–Sep 2022. This is not a calibrated probability for today’s daily inputs.

A forward peak-to-trough price decline—not necessarily a 10% fall from today’s price. No crash-date prediction.

Pillar colors use this layer’s 50 / 65 cutoffs; individual inputs are risk percentiles. Real yields, claims, permits and other slow releases retain their latest available observations. Missing historical pillars are reweighted using available weights.

An advance warning must occur within 12 months strictly before the first 10% breach. It need not precede the market peak.

Fewer alerts—not a universal improvement

In the daily cross-check, the new score was Red 26.8% of the time versus 57.3% for the original cycle score—a reduction of 30.5 percentage points. Both warned before 5 of 5 observed events. Five events are too few to establish reliable future accuracy.

In the long monthly test, the new model catches 1953 but loses the old model’s advance-Red warning for 1987. Its Red misses are 1987, late 2018 and 2020; Amber still warned before all three. Keep the independent 20% layer in view.

One drawdown episode runs until the old peak is recovered. Local corrections inside an unrecovered bear market are not separate episodes. This is not an exhaustive 70-year daily correction inventory.

Definitions, not an improved hit-rate claim

  1. Ongoing drawdown: breach through recovery; classified first.
  2. Advance: the 12 months before a new breach; first Red is independent, later Reds repeat it.
  3. Boundary: 13–18 months before breach.
  4. Unlinked: remaining Red months.

Removing post-breach or boundary observations changes the question. The raw forward-frequency result remains visible above.

How often did a correction follow?

Adjacent months overlap. These are historical month frequencies, not independent event probabilities.

Red4926.5%57.1%71.4%71.4%

Green is not “safe”: even low-stress environments can experience a 10% correction. Scores are not percentages, and crossing a cutoff does not create an instant jump in real-world probability.

Plain-English guide

Use the two layers together.

01

Start with the severity

10% means a correction; 20% means a larger bear-market drawdown. A 10% event can eventually deepen into a 20% event.

02

Look for confirmation

Expand the Market and Credit pillars. Rising risk in both is more informative than expensive valuations alone.

03

Check the tradeoff

Read missed events and time on alert before trusting the catch rate. Amber is a research prompt, not an automatic hedge order.

Why these weights? Selection, sources and limitations

A small, development-only comparison

Three plausible weight sets and four Red cutoffs were compared using 1951–1998. Candidates had to warn before at least 80% of the 11 development breaches; the one with the fewest Red months was selected. Watch is fixed 15 points below Red. The selected parameters were then held unchanged for the later comparisons.

The 10% score is a weighted mean: 0.15 × Valuation + 0.20 × Macro + 0.25 × Credit + 0.40 × Market. Unlike the 20% formula, it has no top-two-pillar blend or confirmation bonus.

  • Monthly history is based on monthly-average prices through Sep 2023, not a complete daily 70-year correction inventory.
  • The monthly reference frequencies are not a calibrated probability for today's daily score: historical and daily pillar inputs differ.
  • Daily diagnostics use actual observed FRED closing dates and the saved daily pillar scores. No daily probability calibration is claimed.
  • An event runs until recovery of the prior peak. Corrections within an ongoing bear market are not counted separately.
  • An advance warning precedes the first 10% breach within 12 months; it may occur after prices have started falling. Breach-date Red is not an advance warning.
  • Revised data and approximate publication lags are not point-in-time vintages. Earlier research examined later historical events.
  • Weights and Red threshold were selected using 1951–1998 only; 1999 is excluded from the later evaluation. The overall study is retrospective, not untouched.
