How HobbyAlpha Reaches a Verdict

Learn how HobbyAlpha combines sold-card evidence, six market signals, player context, confidence, and benchmark-relative grading.

Evidence, signals, and player context

HobbyAlpha starts with recent sold-card activity, price ranges, liquidity, and trend direction. Demand, momentum, liquidity, supply pressure, volatility, and narrative heat are scored alongside career stage, role, performance, injury context, and relevant news.

Confidence describes the quality and agreement of available evidence, not certainty. When exact comps are thin, estimates are labeled and confidence is reduced. Verdict outcomes are evaluated relative to a relevant market benchmark.
