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 28, 2026 1:00 pm
Bear CPNG trends lower to $14.90 (-9.5% from $16.47) by Feb 2027. decay
ThesisCPNG trades well above composite fair value (~$7) with negative sentiment and quality drag, but no imminent catalyst forces revaluation in a risk-on tape. Expect gradual mean-reversion toward the deterministic $14.96 endpoint as the fallen-angel narrative slowly weighs, with mild early stickiness from momentum.
Invalidated ifA surprise profitability beat or strategic catalyst pushing CPNG above $18.50, or regime flip to risk-off driving below $13.50 quickly.

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.
