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.

ride-then-fade
ThesisMA is trading well above every valuation anchor but has strong quality, positive sentiment from a Q2 beat, and a neutral tape with no upcoming catalyst to break the uptrend. Momentum likely carries the stock modestly higher near-term before value gravity and mean reversion begin to bleed the multiple over months 4-6.
Invalidated ifA break below $540 on rising volume, or a sudden regime shift to risk-off, would falsify the ride-then-fade path.

Drift toward deterministic baseline as narrative cools
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
$556.31
(-3.6%)
— both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it.
