AI confidence
Mixed evidenceThe tests show no consistent, material advantage over the no-change baseline.
Model: State-space model, 167M (foundation model)
- Accuracy vs naive
- -1%Matches the no-change baseline over 6 tests (6 tests, 3 won)
- Direction
- 50%No clear edge over a coin flip (36 of 72 calls right in 6 tests)
- Turning points
- 10 of 27Anticipated some turns (27 turns in 6 tests, 0 without a turn)
- Error vs baseline
- 1% higherError ratio 1.01; 1.00 is a tie.
- Tests won
- 3 / 6Complete recent tests excluded from model selection; ties count as no win.
- Test period
- 2020-11-01 to 2026-10-0112 observations ahead per test.
- 80% band coverage
- 80%Observed outcomes inside the band across all stored test windows.
- Band coverage uses all stored test windows, including model-selection windows when present; it does not determine the confidence label.

How this assessment is made
AI confidence describes historical evidence for this forecast, not a probability of being correct. Each backtest fits on data available before its test window. The baseline carries the last value forward. Supported evidence requires at least six complete, non-overlapping tests, an error ratio below 0.90 (rounded to two decimals), and wins in a majority of tests. Ratios from 0.90 to below 1.10 are on par; 1.10 or above is weak evidence. Inconsistent wins produce mixed evidence. For a selected model, only the recent tests excluded from model selection determine this label. These are historical simulations using the available data, not a live trading track record; revisions and foundation-model pretraining can limit how closely they reproduce a past decision. Past performance can change.
Model comparison
5 of 5 models evaluatedModels are selected on older tests and evaluated on separate recent tests. All four classes completed their backtests.
Models tested
State-space model, 167M scored lowest on the 6 older tests (0.98) and was chosen. The 6 recent tests played no part in the choice and give its grade (1.01). The search for a model that beats the naive forecast on both sets of tests goes on. Scores are MASE: a model's errors divided by the naive forecast's, so 1 is a tie.
4 model classes completed the tests: Foundation model, Machine learning, Statistical, Neural network.
