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 24, 2026 1:07 pm
Bear ALAB trends lower to $240.00 (-13.2% from $276.66) by Feb 2027. ride-then-fade
ThesisALAB is a high-beta AI-plumbing momentum name with no valuation anchor and extreme richness on value lens (attractive only below $150). Near-term risk-on tape and narrative keep it bid or push it modestly higher, but 3m vol of 6.8% daily and beta 5 mean any regime wobble triggers sharp mean-reversion; over 6 months gravity pulls back toward the 200-250 zone as the AI-plumbing trade cools.
Invalidated ifA close above 340 on sustained volume, or a break below 230 that fails to recover within two weeks, invalidates the fade thesis; a regime flip to risk_off would accelerate downside.

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.
