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 23, 2026 1:15 pm
Bear GFI trends lower to $41.00 (-14.2% from $47.81) by Feb 2027. ride-then-fade
ThesisGFI is trading well above every fair-value anchor ($47.81 vs $10-14 composite), but gold's crisis-hedge narrative and central-bank buying momentum are dominant near-term drivers in a risk-on regime. Expect continued upward drift over the next 4-8 weeks as sentiment runs hot, then gradual mean reversion as the story cools and value gravity reasserts, though nowhere near fair value within 6 months.
Invalidated ifA break below $42 in the first month, or gold breaking down sharply, would invalidate the momentum leg; conversely a sustained close above $58 suggests the momentum phase runs much longer.

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 $40.98 (-14.3%) — 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.
