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 2:07 am
Neutral ANET trends range-bound to $163.00 (-4.7% from $171.02) by Jan 2027. ride-then-fade
ThesisAI infrastructure narrative and quality moat keep ANET bid despite rich valuation; momentum likely persists near-term but rich multiples and eventual AI capex digestion cap upside, producing a mild drift-then-fade path rather than a sharp mean-reversion.
Invalidated ifBreak below $155 on volume, or a hyperscaler capex cut announcement, would invalidate the sustained-premium 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 $148.28 (-13.3%) — 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.
