Quantum finance: can quantum mechanics forecast stocks?

Status: core — live in production. "Quantum finance" is a real search topic, and Quantustik genuinely runs one: a forecasting engine that models S&P 500 price paths with the Schrödinger equation and Feynman path integrals, layered with an ML regime classifier.

Is it actually calibrated?

3-month: 91.0% CI90 coverage
6-month: 93.3% CI90 coverage
1-year: 90.8% CI90 coverage

All three horizons fall within the well-calibrated [85%, 95%] range against the 90% target, though per-ticker coverage still varies widely — structural-break names like AVGO/BRK-B are poorly covered at the 1-year horizon. These are coverage figures, not a directional hit-rate, and not a claim that the model makes money. Full figures: calibration page.
