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.

ThesisBKNG is riding a Q2 beat and risk-on tape with strong quality and repeated earnings beats, but the current price near $207 is dramatically disconnected from any fundamental anchor - the deterministic model's $1,851 endpoint and $3,500+ fair value suggest either a data artifact or an extreme mispricing. Absent an obvious catalyst to close that gap in 6 months, I expect continued modest upward drift powered by momentum and sentiment, not a violent revaluation.
Invalidated ifA break below $185 or a risk-off regime shift would falsify the drift-higher path; conversely a sudden move above $260 would signal the value gap is closing faster than expected.

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
$1,851.99
(+794.6%)
— both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it.
