How these reports work
Return is ((end price - start price) / start price) × 100. Grades are separate cohorts and never mixed. Cards with invalid, stale or missing start or end prices are excluded; prices are not carried forward. Group rankings use the median of equal-weight card returns. Opening a report reads only stored data and makes no provider request.
