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 23, 2026 3:35 am
Bear HLN trends lower to $9.35 (-5.1% from $9.85) by Jan 2027. ride-then-fade
ThesisHLN trades slightly above composite fair value with modest quality but weak value net; a defensive low-beta name in a neutral tape should drift gently toward the $9.29 deserved-value anchor, with the July 30 earnings print as the near-term swing factor.
Invalidated ifAn earnings beat with raised guidance pushing shares above $10.50, or a miss cracking $9.00, would invalidate the slow-drift 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 $9.74 (-1.1%) — 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.
