AI confidence

Mixed evidence

The tests show no consistent, material advantage over the no-change baseline.

Model: Agentic Investor TSFM (foundation model)

Accuracy vs naive: +1%Matches the no-change baseline over 8 tests (8 tests, 1 won)
Direction: n/aToo few tests (6 direction calls, 8 needed) (4 of 6 calls right in 3 tests)
Turning points: n/aToo few tests (0 turns, 8 needed) (0 turns in 8 tests, 3 without a turn)

Error vs baseline: 1% lowerError ratio 0.99; 1.00 is a tie.
Tests won: 1 / 8Complete rolling backtests; ties count as no win.
Test period: 2003-12-01 to 2026-12-013 observations ahead per test.
80% band coverage: 83%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.

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.
