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 Jul 31, 2026 2:09 am
Bear MPWR trends lower to $1,210.00 (-8.1% from $1,316.18) by Jan 2027. ride-then-fade
ThesisPost-blowout Q2 beat-and-raise refuels the AI-power narrative, driving a near-term push higher, but rich valuation (attractive only sub-$950) and a 3.37 beta into any risk-off tape create gravity over months. Expect a ride-then-fade shape with modest net drift lower by January.
Invalidated ifBreak above $1,450 on sustained volume, or breakdown below $1,150 within a month, would invalidate the drift 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.
