Robust Methodology
Liquidity-screened and weighted by rolling market activity, with quarterly rebalancing and outlier filtering applied to ensure index integrity.
Focused Coverage
The 100 most representative PSA 10 cards by investable market activity, spanning both EN and JP releases.
Settled Data Only
Powered entirely by verified, settled transaction data from major platforms — eliminating dealer estimates and unaudited listings.
Methodology
Each day the index equals the sum of (constituent weight × rolling 30-day interquartile mean PSA 10 price in USD) divided by the rebalance divisor, scaled so the base date equals 100. The divisor chains across quarterly rebalances so index history stays continuous.
The top 100 One Piece cards by trailing 90-day pooled sales volume (Alt.xyz + SNKRDUNK) form the basket. Weights are proportional to volume with the same five-sale minimum and 90-day seasoning rule for new releases. Rebalancing occurs quarterly.
The index tracks PSA 10 GEM MINT copies only, spanning English and Japanese printings. Raw and lower-grade sales are excluded from selection and pricing.
