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 Jul 20, 2026 3:46 am
Bear AME trends lower to $222.00 (-6.3% from $237.00) by Jan 2027. ride-then-fade
ThesisAME is a high-quality compounder trading well above fair value but supported by upgrades and steady-compounder narrative. Expect modest near-term drift with mild fade toward value gravity over 6 months, but no crash absent a catalyst.
Invalidated ifA break below $210 on heavy volume or a guide-down at earnings would invalidate the shallow-fade path; sustained move above $250 would invalidate the 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 $221.17 (-6.7%) — 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 v0.4.0 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.
