ride-then-fade
ThesisSTX is riding an AI-storage narrative to a 100%+ six-month run with beta 2.8 and no fundamental anchor supporting these levels (value lens -84, attractive below $300). Momentum and risk-on regime keep near-term upside plausible, but the extreme dislocation and fragile narrative argue for a fade over months as the story cools.
Invalidated ifA sustained break above $900 on strong volume, or conversely a break below $700 that fails to recover within two weeks, would falsify the gradual-fade path.

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 $0.00 (+0.0%) — both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it. Brain: claude-opus-4-7.

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.
