Methodology
Cap-weighted from confidence-scored fair values, rebalanced monthly with continuous divisor accounting.
Read the full methodologyParent set
Undone SealSet total cap$2.23MCap-weighted, with each constituent dampened by the sales evidence behind its fair value so noisy inputs move the index less. Weekly rebalances with continuous-divisor accounting, so population growth and membership changes never move the level: only price action does. A constituent needs a fair value and a non-zero graded population; sales evidence adjusts its weight rather than gating its inclusion. Per-grade series isolate one tier, composites span PSA 7-10. All values are USD-denominated, base 100 at inception.
