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 Aug 2, 2026 12:40 am
Bear ARM trends lower to $205.00 (-14.5% from $239.69) by Feb 2027. ride-then-fade
ThesisARM is a high-beta AI-royalty narrative stock up 121% in six months with strong sentiment and earnings momentum but deeply stretched valuation (attractive only below $165). Near-term momentum likely persists or drifts higher, but gravity and the eventual next earnings print create risk of a fade into year-end as multiples get scrutinized.
Invalidated ifA break below $200 on volume, or a broad AI-sentiment reset, would invalidate the near-term ride; sustained close above $280 would invalidate the fade.

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 $0.00 (+0.0%) — 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.
