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 4, 2026 1:17 am
Bear SNDK trends lower to $885.00 (-31.3% from $1,288.03) by Feb 2027. ride-then-fade
ThesisSNDK has ripped 123% over six months on the AI-memory/HBF narrative but just took a 47% July drawdown, revealing extreme fragility at beta ~5. With value lens flashing deeply negative (attractive only below $850) and no earnings catalyst to defend the price, I expect a bounce-fade pattern: brief risk-on rally, then multi-month mean reversion toward the $850-950 zone as narrative crowding unwinds.
Invalidated ifA sustained close above $1450 on strong HBF order news, or a regime flip to risk-off accelerating the decline below $700 early, would break this 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.
