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 25, 2026 1:14 pm
Bear ALC trends lower to $66.20 (-9.6% from $73.23) by Feb 2027. decay
ThesisALC trades well above composite fair value ($51-57) with a negative sentiment lens as a marquee holder exits on cataract demand concerns. Low beta and no near-term catalyst mean gradual drift lower toward the anchored-PE zone, not a crash. Value gravity dominates over months while low volatility caps the pace.
Invalidated ifA bullish cataract-volume data point or upgrade cycle lifting ALC back above $76 would invalidate the drift-lower thesis.

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 $70.22 (-4.1%) — both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it. Brain: claude-opus-4-7.

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.
