ride-then-fade
ThesisMRVL is up 178% in six months on an AI-infrastructure narrative with strong momentum, risk-on regime, and euphoric sentiment (+68). Value lens is deeply negative (-69) and quality is weak, but with no fair-value anchor and no imminent earnings catalyst, momentum likely persists near-term before gravity and beta-driven volatility clip gains later in the window.
Invalidated ifRegime flip to risk-off, break below $170 (value trigger), or an AI-capex demand scare would falsify the sustained-momentum leg.

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.

Traditional FCF-based DCF produces misleading results — company reinvests aggressively

EPV is meaningless — the entire value proposition is future growth/optionality

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.
