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. Predicted Sep 18, 2026 1:03 pm
Bear ADI trends lower to $342.00 (-7.5% from $369.91) by Mar 2027. ride-then-fade
ThesisADI trades far above every fundamental anchor with the AI-infrastructure narrative and strong momentum still dominant, so the near-term drifts higher on flows before value gravity and stretched multiples pull it back toward the deterministic baseline over the six-month horizon.
Invalidated ifA decisive break above $400 on sustained volume, or a break below $330 in the first month, would invalidate the ride-then-fade 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 $342.84 (-7.3%) — both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it. Brain: claude-opus-4-7.

Not Yet Modeled

What this v0.6.0 forecast deliberately ignores — the work ahead, in plain sight.
  • Scenario probabilities — one path, no bull/bear split (base_prob = 1.0).
  • Intraday / sub-2-week behaviour — the first claim is at 14 days by design (EOD product).
  • Position sizing / portfolio context — the path is a price claim only.
