dip-then-recover
ThesisNear-term sentiment is negative with CEO warnings on trading/costs and a risk-off tape, so GS likely drifts lower first before value gravity toward the ~$1,018 composite fair value reasserts over months. High beta (1.90) amplifies both legs, and the earnings beat streak plus quality support a recovery back toward baseline by spring.
Invalidated ifA break below $820 on heavy volume, or GS pushing above $990 in the first month, would falsify the dip-then-recover shape.

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 $989.49 (+5.1%) — both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it. Brain: claude-opus-4-7.

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.
