AI confidence

Limited evidence

At least 6 complete tests are required; 3 are available.

Model: Agentic Investor TSFM (foundation model)

Accuracy vs naive: n/aToo few tests (3 tests, 6 needed) (3 tests, 1 won)
Direction: n/aToo few tests (3 tests, 6 needed) (14 of 35 calls right in 3 tests)
Turning points: n/aToo few tests (3 tests, 6 needed) (11 turns in 3 tests, 0 without a turn)

Error vs baseline: 7% higherError ratio 1.07; 1.00 is a tie.
Tests won: 1 / 3Complete rolling backtests; ties count as no win.
Test period: 2023-10-01 to 2026-09-0112 observations ahead per test.
80% band coverage: 56%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.
The 80% band held too few outcomes; interpret its width with care.

This is an evaluation of the serving model; it does not establish a winner across four model classes.

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.
