Forecast
The masterbrain trajectory — 7 dated checkpoints. Short rungs (2w, 1m) show the typical range as the primary claim; point calls run from 2 months out. Every claim still gets graded.

flat-then-break
ThesisBG trades well below composite fair value ($220) with a strong earnings track record, but negative sentiment and quality concerns cap upside. Expect a slow grind higher toward the deterministic baseline as value gravity outweighs sleepy narrative, with early weeks flat before mean reversion asserts.
Invalidated ifA break below $110 on margin guidance cut, or failure to reclaim $125 by November, invalidates the recovery thesis.

Why ranges on the short rungs?
A 102-prediction trial (2026-07-21) showed 2-week point calls carry no information here —
three prompt formulations all lost to simply predicting zero — while the stock's own
volatility scale (σ×√t) described those windows well. So the short rungs claim what's
actually knowable: the typical travel, with earnings timing flagged where the variance
will come from. The internal point calls keep being generated and graded to map where
real skill begins. Full evidence: stocks/predictions/V0.5-DESIGN.md §8.
Deterministic control (v0.3 value line) targets
$146.04
(+23.0%)
— both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it.
