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 12, 2026 1:00 am
Neutral GWW trends range-bound to $1,245.00 (-4.4% from $1,301.94) by Feb 2027. ride-then-fade
ThesisGWW is a durable quality compounder trading well above fair value, but risk-on tape, guide-up momentum, and low beta keep near-term drift positive before valuation gravity slowly reasserts. Expect a modest ride-then-fade, not a crash - the stock rarely gaps down absent a catalyst.
Invalidated ifA break above 1360 on volume with sustained risk-on, or a break below 1240 signaling narrative crack, would falsify the gentle 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 $1,178.59 (-9.5%) — 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.
