ride-then-fade
ThesisJBL is trading at more than 2x composite fair value on AI-infrastructure momentum in a risk-on tape. Near-term the narrative and beat streak likely carry it higher, but with a high-beta 2.07 and no catalyst locked in, value gravity should reassert into winter as AI enthusiasm digests, taking the stock modestly lower toward the deterministic baseline.
Invalidated ifA decisive break above $340 on strong volume, or an AI-infra order announcement, would invalidate the fade; conversely a break below $270 accelerates it.

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 $277.85 (-11.0%) — both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it. Brain: claude-opus-4-7.

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.
