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 19, 2026 11:46 am
Bear KMX trends lower to $47.50 (-20.2% from $59.51) by Feb 2027. ride-then-fade
ThesisKMX rides risk-on momentum and 'last platform standing' narrative near-term as peer weakness lifts sentiment, but rich valuation vs $27-39 fair value range and quality/forensic red flags reassert gravity by winter, especially once a Q3 print lands inside the window.
Invalidated ifA clean earnings beat with used-vehicle unit growth reaccelerating above 5% YoY, or KMX breaking above $65 on volume, 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 $48.71 (-18.1%) — 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.
